1 Overview

The GPA package collects data using an OPC (OLE for Process Control) server anduses this data throughout its calculations, and upon completion of the calculations,broadcasts the calculated values as well as the qualities through the OPC server. Theuse of the OPC server allows the GPA package to connect to OPC compatible datahighways. The GPA package allows the user to choose algorithms organized by groupsto calculate the power plant’s performance.

The Global Performance Advisor (GPA) Package consists of two software packages:1. The GPADCS software is the main software that includes a standard group of

calculations. 2. The PCalcs software is an overlay that adds dozens of Algorithm Modules that

contain custom calculations allowing a thorough evaluation of each system.

The GPA uses Westinghouse Process Control Inc. software (PCalcs) to calculate powerplant performance. GPA integrates advanced digital and analog control functionality,data management, and networking into a complete process automation solution. TheGPA will allow you to accomplish your most challenging control applications whileenjoying the benefits of highly integrated control and monitoring, faster applicationdevelopment, and the enterprise-wide connectivity of Windows NT.

In order to implement this package, you will need an understanding of Westinghousemodules. This document will describe the Westinghouse algorithm modules and how todevelop a project.

1.1 Software Installation and Backup

1.1.1 Installation

The computer should be at least a 900 MHz and have at least 256 MB of RAM to ensurethe program runs smoothly. Complete the following steps to install all software:

1. Place the SmartProcess GPA CD in the CD-ROM drive and install the GPA softwareaccording to the manufacturer's instructions.

2. Run the install software (executable file) provided by Westinghouse, again using the "C"Drive. The following information will be installed. There are seven DLLs that may beshipped with every system, depending on the applications that are copied to the\winnt\system32 directory:

� BLR.DLL� CALCCOMMON.DLL� COMBTURB.DLL� PCALCS.DLL� STMINTERFACE.DLL� STMTABLE.DLL� USERALGSSHAREDRES.DLL

Upon entering the GPA software package, the EVENT.LOG can be checked to verify theversion levels of software. All of the above DLLs should be at the same major versionlevel with the exception of STMINTERFACE.DLL. This DLL is not dependent upon anyof the other DLLs.

A second version of the USERAGLSSHAREDRES.DLL exists for testing and is namedUSERALGSSHAREDRES_FAKE.DLL. If the FAKE DLL is used, all OPC-input valueswill be read in from the initial value field and not the highway. This fake DLL should onlybe used for off-line testing and will be replaced when testing with the highway. TheEVENT LOG will also display the mode for testing which is the FAKE mode.

The PCalcs software CD must be inserted and the PCalcs software loaded.

3. Open the Event Log inside WizDCS and verify that the Major Version Information for allof the DLLs is 3.0 or later except for STMINTERFACE, which will be Version 1.2.

1.1.2 Backing Up the Data Files

During development of the project, the following files need to be backed up on a periodicbasis to prevent data loss:

� Project_name.xref (under %WIZFACTORYSOFTHOME%)� Workspace_name.feqp� Workspace_name.fwsp


05/02 (Rev 2) 3 SP-0030


� Project_name.cprj� All .ffbd documents� All .fdsp files (display sheets)

The .feqp and .fwsp files can be found under the directory where the Workspace wascreated. The .cprj and .ffbd files can be found under the directory where the project wascreated.

GPA Software Installation Checklist� Are all applicable DLLs and cross-reference files copied onto the system?� Is the appropriate USERALGSSHAREDRES.DLL on the system – FAKE or

OPC?� Check the EVENT LOG to ensure that version numbers of DLLs are correct.

Verify that the correct USERALGSSHAREDRES.DLL is on the system.� Are all the appropriate files backed up on a periodic basis?

1.2 Porting a Project to Another Machine

Porting a GPA project requires copying only the eMation WizDCS (Factorysoft) specificfiles, not the supporting DLLs (such as pcalcs.dll, stmtable.dll, useralgssharedres.dll,stminterface.dll and calccommon.dll).

These files consist of:3. The WizDCS Workspace files which house all project(s) (.feqp .fwsp) and the

project-specific files in the Project(s) Directory:

� .cprj (project file)� ffbd (function block diagrams)� .fdsp (display documents)� .csv (registry support files)

Note

Each project within a Workspace has its own directory, soWorkspaces with multiple projects have multiple directories.

4. The .const and .fx files are saved from within algorithms. Recommendation: storefiles in sub-directories within a project directory or, at least on the same disk partition.

5. The .xref files are in %FACTORYSOFTHOME% (typically c:\WizFactory\WizDCS).These files contain all the Tag Group definitions that define the tag configurations forALL algorithms in the project.

Note

Each project within a Workspace has its own .xref file,therefore Workspaces with multiple projects will have multiple.xref files.


05/02 (Rev 2) 4 SP-0030


6. To simplify the zip file to be built:

� Add the .fwsp and .feqp files. � Cursively zip ALL FILES in the project(s) directories. � Add all the project .xref files from %FACTORYSOFTHOME%.

1.3 Program Introduction

Please read Chapter 5 in the WizDCS for Windows "User's Guide". The subjects ofWorkspaces, Projects, Documents, plus Application Preferences and Properties are animportant background for learning how to use this product.

The following definitions may help in understanding the layering WizDCS uses in thebuilding of Projects.

Workspace - Pulls together one or more results provided by a project or set of projectsto form a more complicated result for use in a process.

Project - A set (or sets) of algorithms put together to input information, process it, andoutput useful information.

Functional Block Diagram (FBD) - Comprised of an algorithm or multiple algorithms tocomplete one function.

Algorithm - An Individual building block used to input perform calculations, and outputassigned tags that can be used in other.

Caution

In the unlikely event that two individual Workspaces have to becreated, only one Workspace can be used on a session ofWizDCS. Once a workspace is running in WizDCS, and asecond one is to be called up, the program must be shut downand restarted in order to ensure error free operation.

1.4 Setting Properties and Application Preferences

Follow the instructions in Chapter 5 of the WizDCS "User's Guide" to perform thefollowing:

� Setting the Preferences and/or Properties for various aspects of the program andprojects can be accomplished by following the instructions in Chapter 5 of theWizdcs "User's Guide".

� Setting the different levels of security.


05/02 (Rev 2) 5 SP-0030


2 Startup

This section will briefly describe creating a new project. The following items arediscussed:

� Create a new Workspace � Create one or more New Project (s)� Separating Projects� Create one or more Functional Block Diagram (s)

Note

It would be helpful to work through WizDCS's tutorial tounderstand how to build a project. The Westinghouse overlayworks somewhat differently, but most of the concepts are thesame. Select the Help menu, choose Help Topics, double-clickon the Tutorial booklet, then double-click on WizDCS Tutorialoverview to access the tutorial.

Double-click on the icon to start the GPA program.

Note

Sometimes, when invoking the program, it will seem todisappear. Take the cursor to the bottom of the screen wherethe GPA program bar can be seen. Right-click the bar, andselect "maximize" to pull up the program.


05/02 (Rev 2) 6 SP-0030


2.1 Creating a New Workspace

First, you need to create the new Workspace. This should be a one-time process thatsets up all the projects for the complete facility. 1. On the File menu, select New.2. In the New dialog box, click the Workspace tab. "Control Workspace" is selected

automatically.3. Type the name of the project in the Name text box.

4. Select Navigate and find the Location (or make a new location) where theproject will be kept, then select OK. This places the Workspace with all itscomponents and files in the selected folder.

Notice that other directories were developed when the Workspace was created:

Equipment List - Shows a list of the projects and their running order.

Event Log - A chronological list of events, which can be used for troubleshooting.

Gallery - Not used.


05/02 (Rev 2) 7 SP-0030


2.2 Creating New Project(s)

Next, you need to create a New Project for the current Workspace.

Note

It is important not to name any project the same name as theWorkspace, as the PGA program may confuse the two.

1. Right-click the Workspace name ("Workspace Paul's Power Plant" in this example)in the Workspace Window and select New Project. The New dialog box appearswith "Control Project" selected automatically.

2. Type the desired project name in the Name text box (usually the unit or facilityname). Leave the selection of Add to Current Workspace as is. The Locationoption will, by default, be the same as the Workspace and can be changed if desired.

3. Select OK, this places the new project and its components in the folder.


05/02 (Rev 2) 8 SP-0030


Note

For ease of viewing, set the Zoom factor under the Viewmenu to 75%. For multiple projects, other New Projects andNew Documents can be created. Don't forget to saveperiodically!

We suggest that all of the information for one physical facility (building or unit) be placedin the same "Project". If the plant has more than one unit, each one operatingindependently, a project file should be set up for each. Use Steps 1-3 above to developeach Project.

When working with more than one Project, a separate "dummy" New Project must becreated. This Project does not need any New Documents but will always have to beStarted First, so make sure to give it a name that will allow it to be started first. This"dummy" project is needed to start all the OPC data points. If one project is stopped, theother project’s points will still be collected and broadcast since the "dummy" projectwhich started all the OPC points will still be running.

Simply work through Steps 1-3, and making sure to name the "Dummy" project a namethat will ensure that it is started first (such as "Aaadummy"). Once the "Dummy" projectis created, right-click on the "Project name", then select Set Active Project to ensurethat the program always comes back to this Dummy Project while running. The name willbecome bold, identifying it as the Active Project.

There are also other projects that can be added other than "Control Projects" which willbe discussed later.

Notice that other files were developed when each "Project" was made:

Security - Shows the levels of security set up.

Tags - A listing of all the Tags used in the Project, useful in troubleshooting.


05/02 (Rev 2) 9 SP-0030


2.3 Separating Projects

The decision of when and how to separate GPA projects is driven by factors such asneeding the ability to start/stop projects independently or having multiple highwaysrequiring separate OPC servers.

The are two ways to configure multiple GPA projects to run on the same machine:1. Build a SINGLE workspace (.fwsp file) which contains MULTIPLE projects (.cprj file)

(See "Single Workspace Containing Multiple Projects" below).2. Build MULTIPLE workspaces, each containing a SINGLE project (See below).

Use the following guidelines to choosing which method to use.

2.3.1 Single Workspace Containing Multiple Projects

This configuration is recommended only for cases where the total number of highwaytags for ALL projects number in the low 100's. (This information was obtained from testsperformed on a PC with 333 MHz, 128 MB RAM. These results may vary for PC's withdifferent configurations, you may want to make your own tests).

There are GPA performance issues when the total number of highway tags exceeds the300-350 tag range for workspaces containing multiple projects. The 300-350 range wasobtained from tests performed on a PC with 333 MHz, 128 MB RAM.

To calculate the number of Highway Tags:

# of Highway Tags = # Analog Input + # Digital Input + # Digital Out + (2 X # Analog Out)

(Each analog output tag has an associated quality tag that contains an OPC Item)

2.3.2 Multiple Workspaces Containing a Single Project

This is the most commonly used configuration. With single workspace/projectcombinations, there are currently no known limits (as of PCalcs 3.1) for the total numberof highway tags that will affect performance.

The one requirement when automatically starting multiple workspaces upon reboot isthat the subsequent workspaces must wait (Sleep) until the previous workspaces havestarted and are gathering samples. This is true even if each project has a different OPCServer on different machines. This requirement is VERY important when differentprojects are accessing the SAME OPC server. This interval between startups ofworkspaces must be determined empirically (by observation).

A batch (.com or .bat) file can be built to control this operation. A NEW executable,GPASleep.exe is included in the 3.1 PCalcs release to help facilitate the startup control.


05/02 (Rev 2) 10 SP-0030


Procedure for Executing Multiple Workspaces1. Start up each project, by itself, in debug mode and determine how long it takes to

begin gathering samples. Add some extra time (30 seconds or so) to be sure thenext project won't start too soon.

2. Build a batch file that launches each workspace, and waits for the previousworkspace to start.

3. Add the batch file to the startup folder for reboot.

Here is a sample batch File which starts up 2 workspaces on the same machine:

REMREM Batch File for Starting GPA for Units 1 & 2, with a 60 second Delay in-betweenREMREM **************************************************************************REM Launch Unit #1REM **************************************************************************start c:\gpadcs\bin\gpadcs -r d:\pcalcs\UNIT1.fwspREMREM **************************************************************************REM Sleep 60 seconds, wait for Unit #1 to start gathering samplesREM **************************************************************************GPASleep 60REMREM **************************************************************************REM Launch Unit # 2REM **************************************************************************start d:\gpadcs\bin\gpadcs -r d:\pcalcs\UNIT2.fwsp

Please note that GPASleep has one parameter, which is the # of SECONDS to sleep.Not milliseconds!


05/02 (Rev 2) 11 SP-0030


2.4 Creating a Function Block Diagram (FBD)

Now you need to create one or more FBD documents that contain the control strategyfor each Project. Each Functional Block Diagram will represent a function consisting ofinputs, main projects, or output algorithms. Any number of optional equipment functionalblock diagrams can also be added. See Appendix F - Common Functional BlockDiagrams for examples of some of the different types. 1. Right-click the "Project name" in the Workspace window.2. Select New Document, the New dialog box appears.3. In the Document page (shown by default), under Type, select "Function Block

Diagram".4. In the Name text box, type the "FBD Name" to be used.

5. Leave other parameters at their default values and click OK.

GPA creates a Function Block Diagram folder, adds the new control document to it,and opens it in the document window. When the FBD document is open, thealgorithm window appears and GPA automatically shows the menu commands andtool bars needed for the FBD document.

Note

At the bottom of the algorithm window are tabs that call upsets of algorithms. Included is a special set of algorithmscalled "Calculation Blocks" developed by Westinghouse anddesignated by the prefix "W". The algorithms in these tabscontain specific functions for use with the SmartProcesssystem. There are many Calculation Blocks, and they areorganized into several types. Scroll through the list and look atthe different types. There is a complete list and descriptions ofthese Calculation Blocks (which will be referred to as"Algorithms") in Appendix B - Algorithms (Calculation Blocks).

3 Designing a Functional Block Diagram Document

3.1 Adding Algorithms

Algorithms can be added to format a FBD document (sometimes referred to as a sheet)once an FBD is set up. Typically, each set of FBD documents contain:

� An Input document with :

� At least one Input Algorithm (Analog and/or Digital) from the W Input tab(Section 3.1.2).

� An Ordering Algorithm from the W Input tab (Section 3.1.3).

� A Main document with at least the Chkload Algorithm from the W Main tab(Section 3.1.4), along with any calculation algorithms needed for the project.

� Any amount of documents with "equipment" Algorithms from the available "W"tab groups (Section 3.1.4).

� An Output document with at least one Algorithm from the W Output tab (Section3.1.6).

Note

Several pieces of equipment can be placed on one FBDdocument. But it is suggested, for simplicity and for easytroubleshooting, that an FBD document be made for eachpiece of equipment.

3.1.1 Empty Project Algorithm

The "Emptyproject" algorithm is to be used ONLY in workspaces that contain MULTIPLEprojects. The purpose of this algorithm is to synchronize the startup of all projects,waiting for the "dummy" project (which initializes OPC Highway Item Handles) to startbefore allowing all other projects to start. Workspaces with SINGLE projects do notneed this algorithm, since they self-contain their own startup.

When a workspace with multiple projects is created, a "dummy" project needs to beadded which is made the "Active Project" and is configured to be the first project to start(see Section 2.2 Creating New Project(s)). This "dummy" project's only function is toinitialize OPC handles for ALL tags in ALL projects, thus allowing users to start/stop allthe other projects independently without losing their OPC handles. The "dummy" projectshould always be running.

Note

Even though the "dummy" project starts first, the other projectswant to start immediately afterwards in asynchronized fashion.This can cause problems on the first calculation (average)


05/02 (Rev 2) 14 SP-0030


pass. Since a "zero" value is read for all samples in the realprojects until all the OPC handles have been initialized. Thatresults in false average values in the first pass andsubsequently to false "bad first qualities encountered" in theproject, since the samples have the bogus "zero" values areaveraged in. This Emptyproject algorithm is designed toprevent this from happening.

Configuration:

The "Emptyproject" algorithm has no inputs or outputs to configure, but you must stillpress the "Create/Update Tags in Entire .. Project" to create some behind-the-scenesrequired system control tags.

The Procedure for Creating a "dummy" Project1. Add a "dummy" (empty) project. Make sure it is alpha-numerically named so that it

appears at the top of the project list within the workspace.2. Make sure the "dummy" project is the PRIMARY PROJECT. Do this by expanding

the "Equipment List" workspace tree item, left-clicking on the "Local Machine" treeitem to see the pop-up menu, and then selecting "Properties...".

3. Add an FBD to the "dummy" project.4. Drop two algorithms on the FBD: "Emptyproject" and an "Fbdorder". The "dummy"

project will require ordering.5. Double-Click on the "Emptyproject" Algorythm, press the "Create/Update Tags in

Entire ... Project" button, and create the four required base system operation tags.The configuration of the OPC Server for this project does not matter. You can usethe default name or just delete it.

Note

If you forget to create these system operation tags, a run-timeerror will be in the Event Log asking you to create them.

3.1.2 Input Algorithm(s)

See Input Functional Block Diagram in Appendix F- Common Functional Block Diagramsfor more information.

4. In the algorithms window, scroll over (using the scroll arrows next to the tabs at thebottom of the algorithm window) and choose an "Input" algorithm (Analog or Digital) fromthe W Input tab.

5. Move the mouse pointer into the "Input" document window area. Notice that the mousepointer appears with a rectangular outline.

6. Click once, near the left side of the window, to place the algorithm block.

3.1.7 Copy/Cut/Pasting Algorithms

If a tag set is assigned to an algorithm that has not been configured, or only inputs areconfigured, the tag set is considered unassigned and free to be used anywhere else inthe project. Once an algorithm using this tag set creates an output, the tag set officiallygets assigned to that algorithm.

Note

A Configured Tag Set is a tag set that is in use (assigned to analgorithm) AND creates at least one output.


05/02 (Rev 2) 18 SP-0030


Copy/Paste Within the Same Project

When copying an algorithm within the same project, some of the algorithm properties areretained and some are changed. The Tag Set Name and Project Name are retained.The FBD Name automatically gets changed to the name of the FBD where the algorithmis pasted (dropped).

When a copied algorithm is pasted, all configured outputs are unconfigured. This is dueto the GPADCS rule that outputs can only be created in one algorithm. All inputconfigurations remain as they were before the copy.

When Analoginavg and Digitalin algorithms are copied, their inputs are unconfigured,too. The GPADCS also has a rule that OPC items can only be assigned to a single,unique tag in the project.

Copy/Paste to a Different Project

When copying an algorithm to a different project, only the Tag Set Name gets retained.The Project Name and FBD name automatically are changed to the names in the newproject. All configured output tags are checked to see if some other algorithm in theproject creates them. If so, then the outputs are unconfigured, otherwise the outputconfiguration remains unchanged. Input configurations remain as they were before thecopy.

When copying an algorithm to a different project, the "configured tag set" may not bedefined within that new project. Use the "Get Tag Sets" option on the "Tags" tab folder tocopy the tag set definition from the previous projects cross-reference (.xref) file to thenew projects .xref file. This provides a quick and convenient method of re-usingpreviously defined tag sets and saves a lot of editing.

Cut/Paste Within the Same Project

The "cut" operation is the same as the "delete" operation on algorithms. This means thatall outputs that were created by that algorithm are DELETED from the project. When thepaste is performed, the output tags must be re-created.

When cutting/pasting an algorithm within the same project, some of the algorithmproperties are retained and some are changed. The Tag Set Name and Project Nameare retained. The FBD Name automatically is changed to the name of the FBD wherethe algorithm is pasted (dropped).

Note

Unlike copying an algorithm, a "cut" will not change theconfiguration of the algorithm since any outputs it created willbe deleted.


05/02 (Rev 2) 19 SP-0030


Cut/Paste to a Different Project

When cutting/pasting an algorithm to a different project, only the Tag Set Name isretained. The Project Name and FBD name automatically are changed to the names inthe new project. All configured output tags are checked to see if some other algorithm inthe project creates them, if so, then the outputs get unconfigured, otherwise the outputconfiguration remains unchanged. Input configurations remain as they were before thecut.

When cutting/pasting an algorithm to a different project, the "configured tag set" may notbe defined within that new project. Use the "Get Tag Sets" option on the "Tags" tabfolder to copy the tag set definition from the previous projects cross-reference (.xref) fileto the new projects .xref file. This provides a quick and convenient method of re-usingpreviously defined tag sets and saves a lot of editing.

3.1.8 Inserting FBDs into Projects

Algorithms on FBDs being inserted into a project act the same as if they were"cut/pasted" into the project. The Tag Set Name is retained. The Project Name and FBDname are automatically changed to the names in the new project. All configured outputstags are checked to see if some other algorithm in the project creates them. If so, thenthe outputs become unconfigured, otherwise the output configuration remainsunchanged. Input configurations remain as they were before the insert.

When inserting FBDs into a project, the "configured tag set" for algorithms on the FBDmay not be defined within that new project. Use the "Get Tag Sets" option on the "Tags"tab folder to copy the tag set definition from the previous projects cross-reference (.xref)file to the new projects .xref file. This provides a quick and convenient method of re-using previously defined tag sets and saves a lot of editing.

Recommended Steps to Insert an FBD Into a Project:1. Create a new project with its new directory structure.2. Copy any FBDs (.ffbd files) you wish to insert into the new project's directory

structure.

Note

If you insert the FBDs from another project's directory insteadof copying them, the FBDs get updated for BOTH projectswhen changes are made. This also corrupts the FBD/ProjectNames of algorithms on the FBD for both projects.

The next step only applies for Workspaces with Multiple Projects. SingleWorkspace/Project configurations can ignore this step.3. Make sure the Project the FBDs are going to be inserted into is the "Active Project"

BEFORE inserting them. Failure to do this may lead to the project names assignedto algorithms on the FBD being set to the name of the project which IS currently theactive project.


05/02 (Rev 2) 20 SP-0030


3.1.9 Adding Tag Sets to a Project from External Cross-Reference(.xref) Files.

When algorithms are inserted from one project to another, frequently, the tag setsassigned to those algorithms are not defined in the new project's cross-reference (.xref)file.

The "Get Tag Sets..." (see "Tags Tab" in Chapter 4) feature (invoked by pressing abutton) on the "Tags" tab page on ANY algorithm, provides a quick method for copyingalready defined (template) tag sets from the cross-reference (.xref) file of an existingproject into a new project.

This feature will review the current project for "configured" tag sets and see if they existin the current project's cross-reference file. If they do not, they get added to the "MissingConfigured Tag Sets" list on the main dialog box. A list of all .xref files found in%FACTORYSOFTHOME% is also provided. Simply select a .xref file from that list andpress the "Load Matches" button. All tag set "matches" found in that .xref file are loadedinto a third list. A tag set "match" is found when a tag set's name is found in the external.xref file that exactly matches that of a missing tag set AND the base algorithm type isthe same. Press the "OK" or "Add Selected Sets" buttons to copy selected tag sets fromthe external .xref file into the current project's .xref file

3.1.10 Setting Algorithm Order, Document Order, and FBDProperties

1. After adding the required algorithms in a document, the algorithms must be ordered byselecting Objects, then Set Execution Order, then clicking on the algorithms to set thecorrect order. It is very important that the blocks on a document are ordered, since theblocks will execute in this order.

2. After creating all of the documents in a project, the order of the documents must be set.Go to the Input documents and double-click on the fbdorder algorithm block. Choosethe Design Info tab, and then set the order in which the documents should be run.


05/02 (Rev 2) 21 SP-0030


Setting the FBD Properties

3. Each document (functional block diagram) also needs to have the document propertiesmodified. All FBDs except for the one containing analoginavg and digitalin need to havethe advanced properties change detection rate set to 10000. The FDB containing theanaloginavg and digitalin needs to have the advanced properties change detection rateset to 1000. Right-click on the FDB name and select Properties, then Advanced.Modify the change detection rate field to the correct value. This is EXTREMELYIMPORTANT since the execution time for the project may grow or exceed the scan time.

Functional Block Diagram Checklist� Modify change detection rate for every functional block diagram.� Order algorithms on every functional block diagram.� Make sure the functional block diagrams are ordered using the FBD Order

Algorithm Design tab.

Algorithm Checklist� Check the Tag Mapping list to make sure no tags are left uncreated.� Check the Tag group list to make sure no empty tag groups exist.

4 Run/Debug Mode

In order to start the run/debug mode, go to the project pull-down and select Start fromthe menu. After a short time the bar in the bottom right section will turn green and state"Debug".

The typical "debug" or "(Rum Mode)" dialog box (shown below) is available during GPA"debug" or "run" mode and appears when a user "double-clicks" on an algorithm andselects the "Debug" tag page.

Debug is not available until the project is initialized. A project is initialized when thefollowing text appears in the GPA Event Log: "System READY. Active (Primary) ProjectStarting"

During the Run/Debug mode, most algorithms typically show the information similar tothe screens below (the two exceptions are the Fdborder and Pntvalidate, which will bediscussed later in this section):

4.1 Fdborder

The Fbdorder Algorithm Design Screen now provides useful project-runtime information.This information is available in configuration mode for the LAST execution, AND isavailable in run/debug mode for the current execution. You must execute a project atleast one time after upgrading to 3.1 to see this information.

Note

To get the run-time information during the actual run-time, it isnecessary to press the "Select" button located on the buttonbar on the right side of the frame on the GPA Main Window(the very top button) and get into "config" mode. This button


05/02 (Rev 2) 23 SP-0030


toggles display information from run/debug mode to "config"mode for each and every project within a workspace.

This updated design screen provides:1. The last execution order of ALL algorithms in the project. The columns break down

into Algorithm Name, Overall Project Execution Order, Order within the FBD and thename of the FBD the algorithm resides on. This can be a useful tool for locating aparticular algorithm within all FBDs in an entire project.

2. The place where the first bad quality (from an output) was encountered during thelast/current project execution. The information includes the Tag Name, AlgorithmName, FBD Name and the Calculation Cycle. This is a useful tool for debugging,especially when the first bad quality is found on calculation cycle #1.

3. The last algorithm to execute. This information is helpful when a project hangs oraborts. This will point out the last algorithm to successfully execute, which indicatesthat the next algorithm in the order had the problem. You can then use theinformation included in Item #1 to see what was the problem algorithm.

This screen provides a search box to help you quickly locate an algorithm in theexecution order list.

4.2 Pntvalidate

The following two screen shots show the "debug" and "(Rum Mode)" dialog boxes for thePntvalidate algorithm.


05/02 (Rev 2) 24 SP-0030


5 Setting Algorithm Properties

The Algorithm Properties dialog box contains multiple tabs used to define eachalgorithm. The dialog box for Algorithm Properties will look similar to the one below,although only the Analoginavg algorithm contains the extra Analog Input Averagingsection. Some algorithm blocks contain an extra Design Info tab (described later).

Note

Make sure to save any changes made to the algorithmproperties (using the Save All function in the Files directory).

Tab/Function/Dialog Description

A Tag Names, Units and ValuesThe GPA tag name beginning letter corresponds to the tag’s units. The following tablesummarizes the beginning letters along with the units given to each of these categories.The first unit listed indicates the default units associated with a point. If the units for apoint are different than the default, these units can be selected from the pull down unitlist.

The program will not allow the same tag to be used as an input and output in the samealgorithm.

Every tag’s value is converted upon input to a module. A tag’s value is converted withina unit type to the default units. For example, all points starting with a "w" will beconverted to KLB/HR before the code is executed. All output values are also convertedfrom the default units to the specified units. For example, if power is to be output in HP,the power value inside the code will be in MW and converted to be output in HP.

No explicit conversions need to be performed within a tag group. For example, if a p typepoint or pressure point is input in INHGV, no conversion needs to be done to this point.The value in INHGV will automatically be converted to PSIG. Conversions between unittypes still need to be performed. For example, to go from a "wv" flow to a "w" flow, aconversion needs to take place to go from GPM to KLB/HR. This particular conversion isperformed in the algorithm MASSFLOWLIQUID.

F Common Functional Block DiagramsInput Functional Block Diagram

The GPA package collects data through the input functional block diagram. Thisfunctional block diagram should contain the input algorithms (analog and digital) as wellas the FBD ordering algorithm.

After creating the INPUT DOCUMENT, tab over to the W INPUT algorithm tab. Thisgroup contains the Analoginavg, Digitalin and FBDorder algorithms. The Analoginavgalgorithm inputs OPC server analog values and outputs local GPA averaged analogvalues. The Digitalin algorithm inputs OPC server digital values and outputs local GPAdigital values. The FBDorder algorithm orders the functional block diagrams.

The Analoginavg algorithm CONFIGURATION tab allows the averaged period as well asthe type of average and percentages of samples to be changed. The name can also bechanged to accommodate multiple Analoginavg algorithms. This algorithm along with theDigitalin algorithm(s) should be the first algorithms configured as no other algorithms canbe created until the algorithm’s input points exist.

The TAGS tab allows the points to be created/configured/listed. To create tags, choosecreate/configure tags. The next screen will allow the user to define a new set, list thecurrent sets already defined, choose default units and the OPC server name and node.On the define tag screen, select a point, check the configure box and fill in the pointinformation. After completing the information, select Update List. Continue configuring allthe analog inputs needed. Notice that nothing needs to be done with the output points asthese points are automatically updated from the input list. After configuring all the analoginputs, select the Save or Save as button. If more analog inputs are needed thancontained in the Analoginavg algorithm, a second Analoginavg algorithm can be droppedand configured.

The Digitalin algorithm CONFIGURATION tab does not contain any average information.Only the analoginavg algorithms contain this information. The name and descriptionfields can be modified on this screen.

The Digitalin algorithm TAGS tab allows the points to be created/configured/listed. Afterchoosing the create/configure tags, select the default units as well as the OPC servername and node. On the define tags screen, select a point, check the configure box andfill in the point information. After completing the information, select Update List. Continueconfiguring all the digital inputs needed. Notice that nothing needs to be done with theoutput points as these points are automatically updated from the input list. Afterconfiguring all the digital inputs, select the Save or Save As button. If more digital inputsare needed than contained in the Digitalin algorithm, a second Digitalin algorithm can bedropped and configured.

The FBDorder algorithm only needs the Design Info configured. After adding a functionalblock diagram, the FBDorder algorithm Design Info tab needs to be updated. Note thatthis algorithm must be put on the very first document.


05/02 (Rev 2) 234 SP-0030


INPUT DOCUMENT CHECKLIST� Analoginavg and Digitalin algorithms must be configured first before subsequent

algorithms.� Fbdorder algorithm must be put on the first functional block diagram to order the

functional block diagrams.

Main Functional Block DiagramThe main functional block diagram contains calculations concerning the entire plant,such as checking the load, atmospheric pressure, boiler steam enthalpy and flow, mainsteam enthalpy and flow, rated main steam pressure, rated main steam temperature,first stage pressure, reference main steam flow and the deviation between main steamcorrected flow and reference main steam flow. Any other calculations, such asaverages, pertaining to the entire plant should also be done on this FBD.

The check load algorithm (Chkload) checks the load and will set the flag for the GPApackage to run if the load is above the user-specified load.

The atmospheric pressure algorithm (Patmos) calculates the atmospheric pressureaccording to the barometric pressure.

The boiler steam enthalpy and flow algorithm (Hwblrstm) calculates the boiler steam flowand enthalpy. The flow is calculated according to any flows added and subtracted fromthe boiler steam flow. These flows are selected from the design screen. The enthalpy iscalculated from a steam table call using the temperature and pressure.

The main steam enthalpy and flow algorithm (Hwmnstm) calculates the main steam flowand enthalpy. The flow is calculated according to any flows added and subtracted fromthe main steam flow. These flows are selected from the design screen. The enthalpy iscalculated from a steam table call using the temperature and pressure.

The rated main steam temperature and pressure are calculated as a curve fit and thecurve fit algorithms can be found in the W Curves algorithm section.

The first stage pressure algorithm (P1stg) calculates a correction factor, absolute firststage pressure, rated absolute pressure and corrected first stage pressure.

The reference main steam flow is calculated from a curve fit and the curve fit algorithmscan be found in the W Curves algorithm section.

The main steam corrected flow and deviation algorithm (Wmncor) calculates the mainsteam corrected flow and the deviation from the reference main steam flow.

MAIN INPUT ALGORITHM CHECKLIST� Chkload algorithm must be used first after the analoginavg and digital algorithms.

This algorithm sets the digital flag zdocalc, which allows all other algorithmstoExecute.

"Equipment" Functional Block Diagrams

FEEDHEATER FUNCTIONAL BLOCK DIAGRAM

The feedheater functional block diagram document contains the feedheater algorithm, aswell as any curve fits needed for the design terminal temperature differences and designdrain cooler approaches. The feedheater algorithms are hpfedhtr, lpfedhtr, deaerator, ttdand drnclr. These will be described below.

The hp feedheater algorithm (Hpfedhtr) calculates a heat and materials balance arounda shell and tube type heatExchanger. extraction and drain flows are calculated. Turbineextraction flow and enthalpy are also calculated. This module does not account fordrains pumped forward. The design information needed for this algorithm is as follows:

Feedheater numberIn-service logic – digital signal or feedheater temperature riseOut-of-service logic – cascading drain flow to condenser or anotherfeedheaterExtraction temperature and pressure measurement locationsLeakage existence and the locationAuxiliary leakage split from extraction flow existence

The lp feedheater algorithm (Lpfedhtr) calculates a heat and materials balance around alow pressure shell and tube type heatExchanger. The extraction and drain flows arecalculated for the feedheater. The turbine extraction flow and enthalpy are alsocalculated. This module does not account for drains pumped forward. The designinformation needed for this algorithm is as follows:

Feedheater numberIn-service logic – digital signal or feedheater temperature riseOut-of-service logic – cascading drain flow to condenser or anotherfeedheater and SSR overflow diverted existenceExtraction temperature and pressure measurement locationsLeakage existence and the locationAuxiliary leakage split from extraction flow existence

The deaerator algorithm (Deaerator) calculates the condensate inlet flow, outlet flow,inlet enthalpy and outlet enthalpy for a direct contact heatExchanger. The extractionsteam flow and enthalpy are also calculated. The design information needed for thisalgorithm is as follows:

Reheat and superheat spray flows existence and locationsExtraction temperature and pressure measurement locationsLeakage existence and the location


05/02 (Rev 2) 236 SP-0030


Auxiliary leakage split from extraction flow existence

The drain cooler approach algorithm (drnclr) calculates drain cooler approach anddeviation. The design drain cooler approach for a particular feedheater has to becalculated by a curve fit algorithm before the drain cooler approach algorithm for thisfeedheater is placed on the document.

The terminal temperature difference algorithm (ttd) calculates the terminal temperaturedifference and deviation. The design terminal temperature difference for a particularfeedheater has to be calculated by a curve fit algorithm before the terminal temperaturedifference algorithm for this feedheater is placed on the document.

CONDENSER FUNCTIONAL BLOCK DIAGRAM

The condenser functional block diagram contains the algorithms for condenserperformance. These include the condenser design, condenser average temperature,condenser specific heat, condenser temperature correction factor, and condenseralgorithms.

The condenser design algorithm (Cnddesign) reads in the condenser design information.The design information along with the length, outer diameter, bwg, condenser materialcorrection factor and thickness are all assigned to output points. The inner diameter isalso calculated for the compartment(s).

The condenser average temperature algorithm (cndavgtemp) calculates the condenseraverage inlet and outlet temperature as well as the average circulating watertemperature.

The condenser specific heat algorithm (Cndspecheat) calculates the specific heat of thecondenser circulating water temperature.

The condenser temperature correction factor is calculated as a curve fit. The curve fitalgorithms can be found in the W Curves section of the algorithms.

The condenser algorithm (Condsr) determines the method for out-of-servicecompartments. After checking for out-of-service compartments, the specific heat,specific volume and specific gravity of circulating water are calculated. Next, thecondenser duty, the condenser circulating water flow, the actual and design heattransfer, the cleanliness factor,Expected back pressure with clean tubes and thebackpressure deviation are calculated. The calculations are done in accordance withASME Power Test Code PTC 12.2 (1983) and HeatExchange Institute Standards forSteam Surface Condensers, Ninth edition.

STEAM TURBINE FUNCTIONAL BLOCK DIAGRAM

The steam turbine functional block diagram document contains the generator-relatedalgorithm and the turbine stage efficiency algorithms.

The generator algorithm (Gennet) calculates the generator mva, the generator powerfactor, the auxiliary power, the ratio of auxiliary power to gross power, the total shaft


05/02 (Rev 2) 237 SP-0030


power and generator efficiency. Variable generator losses need to be calculated beforethis algorithm by a curve fit.

Next, any flows and leakages associated with the high-pressure stage need to becalculated by using W Curves algorithms and W Math algorithms. After these arecalculated, the high-pressure design efficiency needs to calculate by a curve fitalgorithm. Finally, the turbine algorithm should be used for the hp stage. The turbinealgorithm (turbin) calculates the turbine inlet enthalpy, the turbine outlet flow, the turbineoutlet enthalpy, the isentropic enthalpy and the turbine efficiency.

The calculations for the intermediate pressure stage are done the same as the high-pressure stage. Flows and leakages associated with the intermediate pressure stage arecalculated and then the turbine algorithm should be used for the intermediate stage.

The low pressure stage efficiency is calculated by summing the total heat and dividingby the total flow. The mixer algorithm can be used to calculate the total heat. Next, thedesign low pressure efficiency is calculated by a curve fit and the low pressure efficiencydeviation is calculated using a subtraction algorithm.

Lastly, the stage(s) used energy and the condenser vapor enthalpy are calculated.

BOILER FUNCTIONAL BLOCK DIAGRAM

The boiler functional block diagram contains the fuels, modified air heater temperature,boiler, corrected boiler efficiency and air heater algorithms. The design boiler efficiency,designExcess air and design air heater air inlet temperature also needs to be calculatedon this document.

The fuels algorithm (Fuels) is under the W Fuel tab and performs a fuel analysis on thetotal fuel(s) used. This algorithm requires design information.

The modified air heater temperature algorithm (modahtemp) calculates the air heaterleakage and modified outlet temperature for the air heater(s).

The boiler algorithm (Boiler) calculates the boiler efficiency by the heat loss method.Before this module is used, the design boiler efficiency, designExcess air and design airheater air inlet temperature need to be calculated by a curve fit.

The corrected boiler efficiency (Corblrloss) calculates the corrected boiler efficiency anddeviation.

The air heater algorithm (Airhtr) monitors the performance of the air heater. It computesthe x-ratio, the air side efficiency and the gas side efficiency.

FAN FUNCTIONAL BLOCK DIAGRAM

The fan functional block diagram contains the fan design, the density correction, designdischarge pressure, design horsepower, design fan motor efficiency (if available) and thefan algorithm. The fan airflow isExpected to be in volumetric units. If the airflow is not involumetric units, the Volflowgas algorithm under the W Misc tab can be used to change

MATH ALGORITHMS

There are two sets of math algorithms. A GPA set (Math) and a Westinghouse set (WMath). All the Westinghouse math algorithm results can be modified by a gain and bias.The result is multiplied by a gain and then increased by the bias. The total gain iscomprised of an analog input gain value and a constant gain value. The total bias valueis comprised of an analog input point bias value and a constant gain value. The defaultvalue for the constant gain value is 1 and the constant bias value is 0 so if the user doesnot need to gain or bias the results, the constants do not need to be modified and theanalog input gain and analog input bias points do not need to be configured. TheWestinghouse math algorithms consist of the following:
