Business Objective

► Plant Optimization► Reduce Downtime► Effective Alarm Localization► Nuisance Alarm Identification► High Availability► Cost effective Solution

Operational Objectives

► Root Cause Analysis► Alarm History ► Local Alarm Indication► Fast and Reliable Event Capture► Redundancy of I/O Processors

Agenda

Selection of Solution

► Local SI for Local Support► Wonderware SCADA selected for► Ease of configuration ► Minimal effort to integrate Date and Time

Stamp at source event streams through OPC server

Sequence of Events Recording System

System Implementation

► 960 Relay Contact Inputs COS monitoring► 960 Alarm Statuses Annunciated► Input discrimination to 200μseconds► Minimum Pulse Width 500μseconds► Time Stamping Accuracy 200μseconds

Disadvantages of Poll Response

Disadvantages of a poll/response network · Poll/Response uses %100 of available bandwidth.· The data "Transport" is the "Application". You can't break them apart.· One protocol for all field equipment limits deployment of new technology & impedes migration to new topologies.· It is not a "managed" network.· One-to-One data relationship between the Host and field equipment Master Slave

Benefits / Goals Achieved

► Root Cause Analysis ► Alarm History ► Local Alarm Indication ► Fast and Reliable Event Capture ► Redundancy of I/O Processors

Realised Benefits

► 90% improvement in Root cause analysis► 25% improvement in Generating Availability► 40 to 50% time saving in Maintenance► Huge Saving on Hard Wired Annunciation► Project Implementation Short► End User Empowerment on system usage,

migration and on going improvement► Rapid Deployment of next Generator

system

Agenda

Lessons Learned

► Learn to Speak Greek ! Real Greek

► Partnering with local Wonderware SI’s essential► Preconfigured Wonderware for Front end

Hardware from Factory simplifies field work

Agenda

Conclusions

► Wonderware was a good choice for seamless integration of Date and Time stamped events into an HMI for management of Alarm and Events.

► Wonderware Presence worldwide presented this opportunity for us from a South African and UK Base.

Project summary

► “The system works well and enables incidents to be tracked very efficiently”. Ilias Kalaitzis ,Project Engineer, Control Systems

Project Summary

► Project Delivered in 2008 on time during Shut Down of Generator Unit Period 16 Weeks Entirety

► Second Unit simple Copy and Paste for SOE Configuration. Completed Dec 2008

► We are expecting orders for the balance of

2 Generator Sets
