Overview Changes

Hardware Diagram Software DIFF

No modifications No modifications Note: This version is not released for applications with IEC 61850 systems! Version -610-714 may be used as an alternative.

Bug fixing: In versions -606 to -610 inrush signaling from all three measuring systems was suppressed when harmonic blocking in measuring system 1 was triggered. This was not accompanied by tripping. Nevertheless there was the possibility of an overreaction (tripping) when an inrush condition was not recognized by one measuring system with the operating mode set to "Not phase-selective" and in an other measuring system the second harmonic component reached a value of approximately between 70% and 130% of the fundamental.

FT_DA

Bug fixing: The fault data for F T _ D A : F a u l t c u r r . I Y , b p . u . (026 088) were mistakenly calculated on the basis of current IY,a. No modifications No modifications This version is not released.

Bug fixing: The sequence of M A I N : G e n e r a l s t a r t i n g (036 000) and D I F F : T r i p s i g n a l (041 075) have been changed such that starting always comes first. No modifications No modifications Bug fixing: The cause for a break in the client-server communications link after approximately 49 days for about 20 minutes has been removed. GOOSE and GSSE were not affected by this break in the client-server communications link. As an ordering option for the 40TE and 84TE model versions there is now a variant available with a detachable HMI. The detachable HMI is always supplied with a case width of 40TE. The detachable HMI provides the following new features: 6 freely configurable function keys as well as 6 freely configurable LED indicators (H18 to H23) each situated next to a function key. The freely configurable LED indicators (H4 to H16 and H18 to H23) are provided as multi-color LEDs. Note: When the local control panel is ordered together with a detachable HMI for version -306, it is delivered with function keys and multi-colored LED indicators fitted. Otherwise the earlier local control panel is delivered without having function keys and multi-colored LED indicators fitted. With version -307 and irrelevant of the ordering option, the local control panel is delivered with function keys and multi-colored LED indicators fitted.

Version Software LOC

Changes Because of the ordering option "detachable HMI" this additional Device Identification parameter is now available: L O C : L o c a l H M I exists (221 099). Respective binary signal inputs (if previously unavailable) are assigned to all default reset functions. These binary input functions are now available in the configuration list for the two newly implemented group resetting functions as well as the extended functional assignment for the CLEAR key ('C'): MAIN: MAIN: LOC: Fct.assign. reset 1 Fct.assign. reset 2 Assignment reset key (005 248) (005 249) (005 251)

LOC MAIN

Two menu jump lists may now be configured. These menu jump lists make it possible to select individual menu points (i.e. set values, counters, triggering functions, event logs) in a freely definable sequence. LOC: Fct. menu jmp list 1 LOC: Fct. menu jmp list 2 IEC (030 238) (030 239)

Implementation of active monitoring of the communications data links to logged-on clients with the parameter I E C : T C P k e e p - a l i v e t i m e r ( 1 0 4 0 6 2 ) . This active monitoring now replaces previous passive monitoring using parameter IEC: Inactivity timer (104 050). Implementation of an automatic switchover to daylight saving time, activated by parameter I E C : S w i t c h . d a y l . s a v . t i m e (104 219). Switchover times for the automatic switch to daylight saving time are governed by the following settings: IEC: IEC: IEC: IEC: IEC: IEC: IEC: IEC: Dayl.sav.time start Dayl.sav.time st. d Dayl.sav.time st. m Dayl.sav.t.st.0:00 + Dayl.sav.time end Dayl.sav.time end d Dayl.sav.time end m Dayl.sav.t.end 0:00+ (104 220) (104 221) (104 222) (104 223) (104 225) (104 226) (104 227) (104 228)

A second SNTP server may now be applied for time synchronization. Should no answer be transmitted by the first SNTP server the next request is automatically transferred to the second SNTP server (backup function). IEC: SNTP server 1 IP IEC: SNTP server 2 IP (104 202) (104 210)

Instead of setting a router address and target network, so as to establish a communication link to a client situated exterior to the local network, now only the setting of the gateway address is required via I E C : G a t e w a y a d d r e s s (104 011). Now 'unbuffered reports' are available for all logical nodes.


U-7


Version LED

Changes The new detachable HMI provides the following extended display functionalities: The operating mode for the LED indicators has been extended by the operating mode LED flashing. Two differing signals may now be assigned to the freely configurable LED indicators (H 4 to H 16 and H 18 to H 23) to emit either red or green light. If both assigned signals are active the resulting LED color will be 'amber' (yellow). Configuration, operating mode and physical state of the permanently configured LED indicators H1 and H17 are now displayed via configuration parameters and physical state signals. F_KEY CBF_1 ... CBF_3 The new detachable HMI provides 6 freely configurable function keys operated either as a key or switch with or without password protection. Implementation of the new circuit breaker failure protection function including a current reset criterion. Depending on the number of ends on the protected object there are up to 4 function groups available. No modifications No modifications Bug fixing: Reset functions configured to the CLEAR key ('C') are now carried out correctly. A system restart could previously occur when the detachable HMI was disconnected. Bug fixing: The fault data for differential current and restraining current issued by the ground differential protection functions REF_2 and REF_3 are now also calculated correctly when the operating mode is set to "Low imped. / IP,max" (previously they had twice the value). When the differential protection is triggered these functions are now blocked as long as at least one of the following conditions is met: D I F F : M e a s . s y s t e m 1 t r i g g . (041 124) D I F F : M e a s . s y s t e m 2 t r i g g . (041 125) D I F F : M e a s . s y s t e m 3 t r i g g . (041 126) Timer stages 't1 3p' and 't2' of functions CBF_2CBF_4 are now processed regardless of the setting at CBF_1. The ICD files have been modified. urcbMX has been added to the logical nodes PhsPDIF1, Rf1PDIF1, Rf2PDIF1 and Rf3PDIF2. Implementation of the communication protocol IEC 61850 in these versions is KEMA certified.

Changes No modifications No modifications The data model of the measured operating values for differential current and restraining current in the functions DIFF and REF_n is now implemented according to the data attributes for the standard WYE, ACT and ACD classes. Note: With this implementation, the "phase" measured values from the DIFF protection functions correspond to the measured values of the three measuring systems: "phSA" = Measuring system 1 "phSB" = Measuring system 2 "phSC" = Measuring system 3 Accordingly the measured values from the REF_n protection functions are modeled as "neut". ICD and PICS-MICS-ADL files have been upgraded accordingly.

P631/P632/P633/P634 Changes in software version -610 to -620

2 2.1 Function keys on the front panel user interface (HMI)

Operation Configuration of the Measured Value Panels (Function Group LOC)

The new detachable HMI (as of version -611) provides 6 freely configurable function keys. Either a single function, one of the two group resetting functions or one of the two menu jump lists may be assigned to each of these function keys with the setting parameter F _ K e y : F c t . a s s i g n m . F x (Fx: F1 to F6). As an example the operation of function key F1 is shown in figure U-2 Function key F1 is only enabled after the associated password, as defined at F _ K E Y : P a s s w o r d f u n c t . k e y 1 , has been entered. After the password has been entered the function key will remain active for the time period set at F _ K E Y : R e t u r n t i m e f c t . k e y s . Thereafter, the function key is disabled until the password is entered again. The same is valid for function keys F2 to F6. Further information on the function keys and their application can be found in section 'Configurable Function Keys (Function Group F_KEY)' and section 'Resetting Mechanisms' as well as in section 4.2 'Configurable Function Keys F1 to Fx (general)' and section 4.3 'Configurable Function Keys F1 to Fx particularly as control keys'. Note: Each of the 6 keys has an LED indicator situated next to it which is freely configurable, such as the other 12 LED indicators, but independent of the configuration of the function keys (i.e. the function assignment is for red and green light emission). Selection of the control point (P632, P633) As of version -620 the function keys available on the units P632 and P633 can also be configured as control keys (e.g. Local/Remote, Device Selection, Device OPEN, Device CLOSE). See figure U-1 and section 'Configurable Function Keys F1 to Fx particularly as control keys (P632, P633 only)'. Therefore new settings have been added to function group HMI. Switchgear units can be controlled from a remote location or locally. Switching between local and remote control is achieved using either an appropriately configured function key or an external key switch. The position of this switch is checked via an appropriately configured input (configuration at M A I N : I n p . a s g . L / R k e y s w . ) For further information on the application of a function key to switch the control point from 'Local' to 'Remote' refer to sections 'Configurable Function Keys (Function Group F_KEY)' and 'Configurable Function Keys F1 to Fx particularly as control keys'. The setting at L O C : F c t . a s s i g n . L / R k e y determines whether the control point is switched (using either the L/R key or the key switch) from 'Local' to 'Remote' control (LR) or from 'Local+Remote' to 'Local' control (R&LL) and back again. If only remote control is enabled then there will be a local access blocking. If only local control is enabled then there will be a remote access blocking.

Only one control command is executed at a time, i.e. further control requests issued by other clients during the execution of such a command are rejected. To have clients control switchgear units (external devices) the following operating modes can be set at I E C : D E V c o n t r o l model: Control service mode Direct control with enhanced security SBO (Select before operate) with enhanced security When set to the operating mode Select before operate the switchgear unit is selected by the client before the control command is issued. Because of this selection the switchgear unit is reserved for the client. Control requests issued by other clients are rejected. If, after a selection no control command is issued by the client, the P63x resets this selection after 2 minutes have elapsed. The switchgear units contact positions signalled to the clients are made with the Report Control Blocks of the switchgear units.

2.3

Configurable Function Keys (Function Group F_KEY)

The P63x includes six additional function keys that are freely configurable. Function keys F1 to Fx will only be enabled after the password has been entered at F_Key: Password funct. keyx. As an example the operation of function key F1 is shown in figure U-2. After the password has been entered the function key will remain active for the time period set at F _ K E Y : R e t u r n t i m e f c t . k e y s . Thereafter, the function key is disabled until the password is entered again. The same is valid for function keys F2 to F6. Exception: If a function key is configured as a control key a password request is only issued when the command "Local/Remote switching" has been assigned to this function key. Configuration of function keys with a single function Each function key may be configured with a single function by selecting a logic state signal at F _ K E Y : F c t . a s s i g n m . F x (Fx: F1 to F6), but with the exception: L O C : T r i g . m e n u j m p x E X T (x: 1 or 2). This function is triggered by pressing the respective function key on the P63x. Configuration of the function keys with a group resetting function Respective binary signal inputs (if previously unavailable) are assigned to all default reset functions. Instead of a single function each function key may have one of the two group resetting functions assigned at F _ K E Y : F c t . a s s i g n m . F x (Fx: F1 to F6) by selecting the listing at M A I N : G r o u p r e s e t x E X T (x: 1 or 2). By pressing the assigned function key all (up to 10) reset actions selected at M A I N : F c t . a s s i g n . r e s e t x (x: 1 or 2) are triggered. Configuration of function keys with menu jump lists Instead of a single function each function key may have one of the two menu jump lists assigned at F _ K E Y : F c t . a s s i g n m . F x (Fx: F1 to F6) by selecting the listing at L O C : T r i g . m e n u j m p x E X T (x: 1 or 2). The functions of the selected menu jump list are triggered in sequence by repeated pressing of the assigned function key. Both menu jump lists are assembled at L O C : F c t . m e n u j m p l i s t x (x: 1 or 2). Up to 16 functions such as setting parameters, event counters and/or event logs may be selected. Note: LED indicators including the six positioned directly next to the function keys are configured independently and in this respect there is no relationship to the respective function key configuration.

U-16



Configuration of function keys as control keys (P632, P633 only) Each function key may be configured as a control key by selecting one of the listings at F _ K E Y : F c t . a s s i g n m . F x (Fx: F1 to F6). MAIN: Local/Remote key MAIN: Device selection key MAIN: Device OPEN key MAIN: Device CLOSE key

These control functions may only be used sensibly if all four of the above commands have been configured thus engaging four of the available six function keys. Operating mode of the function keys For each function key the operating mode may be selected at F _ K E Y : O p e r a t i n g m o d e F x (Fx: F1 to F6). Here it is possible to select whether the function key operates as a key or as a switch. In the operating mode 'Key' the selected function is active while the function key is pressed. In the operating mode 'Switch' the selected function is switched on or off every time the function key is pressed. The state of the function keys can be displayed. Exception: For function keys configured as control keys the operating mode is irrelevant and it is therefore ignored. Handling keys If backlighting for the LC display is switched off it will automatically light up when a function key or the "READ" key is pressed. The assigned function will only be triggered when the respective key is pressed a second time. This is also valid for the other keys.

2.4 Filter function

Configuration and Operating Mode of the Binary Inputs (Function Group INP)

An additional filter function may be enabled in order to suppress transient interference peaks at the logic signal inputs (operating modes 'Active "High", Filt.' or 'Active "Low", Filt.'). With this function enabled a status change at the binary logic input is only signalled when the input signal remains at a steady signal level during a set number of sampling steps (sampling step size = period / 20). The number of sampling steps is set at parameter I N P : F i l t e r .

Main Functions of the P63x (Function Group MAIN) Acquisition of Binary Signals for Control - (P632, P633 only)

In the acquisition of signals for control purposes, the functions real time acquisition (time tagging), debouncing and chatter suppression are included as standard. Each of these signals can be assigned to one of three groups and for each of these groups the debouncing time and chatter suppression can be set. Matching of these two parameters achieves the suppression of multiple spurious pickups.

U-21


Debouncing The first pulse edge of a signal starts a timer stage running for the duration of the set debouncing time. Each pulse edge during the debouncing time re-triggers the timer stage. If the signal is stable until the set debouncing time elapses, a telegram containing the time tag of the first pulse edge is generated. As an alternative the time tag may be generated after debouncing by setting parameter M A I N : T i m e t a g to the value 'After debounce time'. After the set debouncing time has elapsed, the state of the signal is checked. If it is the same as prior to the occurrence of the first pulse edge, no telegram is generated. Time-tagged entries of the first pulse edge are only generated after debounce time has elapsed. If these entries are saved without delay (setting of M A I N : T i m e t a g to the value '1stEdge,OpMem unsort') they are not necessarily saved in chronological order in the operating data memory. If above parameter has been set to the value '1stEdge,OpMem sorted' then all entries are always saved in chronological order in the operating data memory.

2.6.2

Selection of the Bay Type - (P632, P633 only)

The P63x is designed to control up to three switchgear units. The Bay type defines the layout of a bay with its switchgear units. The P63x offers a selection from pre-defined bay types. Should the required bay type be missing from the standard selection then the user can contact the manufacturer of the P63x to request the definition of a customized bay type to download into the P63x. By applying the bay editor from the PC Access Software MiCOM S1 the user can also define new bay types. The number of this additional bay type will then be displayed at MAIN: Customized bay type. Once the user has selected a bay type, the P63x can automatically configure the binary inputs and output relays with function assignments for the control of switchgear units. The assignment of inputs and outputs for an automatic configuration is shown in the List of Bay Types in the Appendix.

Function Blocks - (P632, P633 only)

By including function blocks in the bay interlock conditions, switching operations can be prevented independent of the switching status at the time, for example, by an external signal "CB drive not ready" or by the trip command from an external protection device. Binary input signals conditioned by debouncing and chatter suppression or output signals from the programmable logic function can be assigned to the function blocks 1 and 2 by setting a '1 out of n' parameter. The input signal from the function blocks starts a timer stage and after it has elapsed, the signal M A I N : F c t . b l o c k . x a c t i v e is issued.

2.6.4

Coupling between Control and Protection for the CB Signals (P632, P633 only)

Bay type selection defines the external device (DEV01 or DEV02 or ...) that represents the circuit breaker. Coupling between control and protection for the "Closed" position signal is made by the setting at M A I N : S i g . a s g . C B x c l o s e d (x = 1 to 4). In the same way coupling between control and protection for the "Open" position signal is made by the setting at M A I N : S i g . a s g . C B x o p e n (x = 1 to 4). As a result, the CB status signal needs to be assigned to a binary signal input only if this coupling is implemented. Note: With all unit versions, P631 to P634, these signal assignments are visible for four circuit breakers, but can only be used with P632 and P633 according to the number of supported CBs.

Multiple Signals - (P632, P633 only)

The multiple signals 1 and 2 are formed by the programmable logic function using OR operators. The programmable logic output to be interpreted as multiple signaling is defined by the configuration of the binary signal input assignment with the corresponding multiple signaling. Both an updated and a stored signal are generated. The stored signal is reset by the following actions: General reset Latching reset The LED indicators have been reset. A command received through the communication interface. If the multiple signaling is still present at the time of a reset, the stored signal will follow the updated signal.

Enable for Switch Commands Issued by the Control Functions (P632, P633 only)

Before a switching unit within the bay is closed or opened by the control functions of the P63x, the P63x first checks whether the switch command may be executed. A switch command will be executed if the optional control enable has been issued and the interlock conditions are met. The interlock conditions are defined in the interlocking logic for each switching unit within the bay that is subject to control actions and for each control direction (Open/Close). Different conditions are defined for the bay interlock equations to operate with or without station interlock. The check of bay or station interlock equations can be cancelled for all electrically controllable switchgear units within a bay. If the station interlock is active, it may be cancelled selectively for each switching unit and each control direction (see section Control and Monitoring of Switchgear Units'). If Local has been selected as the control point, the bay and station interlocks may be cancelled through an appropriately configured binary signal input.

Resetting Actions

Stored data such as event logs, measured fault data etc, can be cleared in several ways. The following resetting actions (as of version -611) are available: Automatic resetting of the event signals provided by LED indicators (given that the LED operating mode has been set accordingly) and of the display of measured event data on the front panel LCD whenever a new event occurs. In this case only the displays on the front panel LCD are cleared but not the internal memories such as the fault memory. Resetting of LED indicators and measured event data displayed on the front panel LCD by pressing the "CLEAR" key C located on the front panel user interface (HMI). By selecting the required function at L O C : F c t . r e s e t k e y further memories may be assigned which will then also be cleared when the "CLEAR" key is pressed. Selective resetting of a particular memory type (e.g. only the fault memory) via setting parameters. (For this example: Navigate to menu point F T _ R C : R e s e t r e c o r d . U S E R and set to 'Execute', see also the exact step-for-step description in section 'Reset'.) Selective resetting of a particular memory type (e.g. only the fault memory) through appropriately configured binary signal inputs. (For this example: Assign parameter F T _ R C : R e s e t r e c o r d . E X T to the relevant binary signal input e.g. I N P : F c t . a s s i g n m . U 1 2 0 1 .) Group resetting by setting parameters, by navigating to menu point M A I N : G r o u p r e s e t x U S E R and setting it to 'Execute'. For this the relevant memories (i.e. those to be reset) must be assigned to parameter M A I N : F c t . a s s i g n . r e s e t x . Group resetting through appropriately configured binary signal inputs. (That is assign parameter M A I N : G r o u p r e s e t . x E X T to the relevant binary signal input, e.g. I N P : F c t . a s s i g n m . U 1 2 0 1 after memories to be reset have been assigned to parameter M A I N : F c t . a s s i g n . r e s e t x .) General resetting by setting parameters (menu point M A I N : G e n e r a l r e s e t U S E R ). All memories, counters, events etc. are reset without any special configuration options. General resetting through appropriately configured binary signal inputs. (M A I N : G e n e r a l r e s e t E X T is assigned to the relevant binary signal input.) All memories, counters, events etc. are reset without any special configuration options. Should several resetting actions have been configured for one particular memory then they all have equal priority. In the event of a cold restart, namely simultaneous failure of both internal battery and substation auxiliary supply, all stored signals and values will be lost.

U-34



Further resetting possibilities are basically not distinct resetting actions but make access especially easy to one of the resetting actions described above i.e. by configuring them to a function key. Function keys may be configured such that resetting of a specific memory is assigned. Technically this is similar to resetting through an appropriately configured binary signal input. When a function key is pressed a signal to a binary signal input is simulated. (See section 'Configurable Function Keys'.) Similar to this, but one step less direct, is the possibility to assign one of the two menu jump lists (L O C : T r i g . m e n u j m p x E X T ) to a function key and to include the relevant menu point for a resetting action (e.g. O U T P : R e s e t l a t c h . U S E R ) in the definition (L O C : F c t . F c t . m e n u j m p l i s t x ) of the selected menu jump list. The same may be achieved with the "READ" key by assigning it a menu point for a resetting action through L O C : F c t . r e a d k e y .

Circuit Breaker Failure Protection (Function Groups CBF_1 to CBF_4)

As of version P63x -611 the new version of the circuit breaker failure protection function, identical with all Px3x protection devices, has been implemented. Depending on the design version this function group is repeatedly available so that a dedicated function may be applied to each end on the protected object. P631: P632: P633: P634: CBF_1 and CBF_2 CBF_1 and CBF_2 CBF_1 to CBF_3 CBF_1 to CBF_4

The following specifications apply to assigning these 4 functions to the physical measured current values and the internal logical signals. Assigning ends The currents to be monitored by the respective CBF function may be selected using setting parameters:Address Description 022.156 CBF_1 022.157 CBF_2 022.158 CBF_3 022.162 CBF_4 Select. meas. input Select. meas. input Select. meas. input Select. meas. input Range of Values End a End b End c End d Current summation Units

Assigning CBs

Each CBF_x function is permanently assigned to the respective circuit breakers CBx. This concerns monitoring of the CB contact positions in conjunction with the MAIN function of the protection unit. There are no specifications concerning the assignment of circuit breakers to ends on the protected object.

Assigning the trip command

Which of the trip commands is to be used as a start criterion for the respective CBF function may be selected by setting parameter:Address Description 022.202 CBF_1 022.216 CBF_2 022.230 CBF_3 022.244 CBF_4 Fct.assign. starting Fct.assign. starting Fct.assign. starting Fct.assign. starting Range of Values MAIN MAIN MAIN MAIN Gen. Gen. Gen. Gen. trip trip trip trip signal signal signal signal 1 2 3 4 Units

The functional range made available by the circuit breaker failure protection function CBF_1 is documented in the following description. Function groups CBF_2 to CBF_4 provide the same functional range.

P63X/EN AD/Ak6 // AFSV.12.10110 DE /// P631-306/307/308-611/620 // P632-306/307/308-611/620 // P633-306/307/308-611/620 // P634-306/307/308-611/620

U-37


However, after release of the device software version -611 the following dependencies between functions have been identified: The following limitation in setting timer stages (bug fixed as of version -620) is present in software versions -611 and -611-71x: In function groups CBF_2 to CBF_4 the parameter "Delay/fault beh. CB" (addresses 022 227, 022 240 and 022 254) cannot be set to 'Blocked'. It is not possible to completely switch off this sub-function. This does not cause a problem regarding protection functionality as, firstly, the same effect is achieved by setting a timer stage with a delay time of 100 s and, secondly, the signal "Fault behind CB" may be ignored by not using it. Only with version -611 the following links exist for timer stages 't1 3p' and 't2' (bug fixed as of version -611-716): Timer stages C B F _ 2 : t 1 3 p ; C B F _ 3 : t 1 3 p ; C B F _ 4 : t 1 3 p are processed as 'blocked' if C B F _ 1 : t 1 3 p is set to 'Blocked'. Timer stages C B F _ 2 : t 2 ; C B F _ 3 : t 2 ; C B F _ 4 : t 2 are processed as 'blocked' if C B F _ 1 : t 2 is set to 'Blocked' . If these timer stages in CBF_1 are not set to 'Blocked' the timer stages in CBF_2 to CBF_4 will be processed as set. If 'Blocked' has been selected for this setting then a delay time of 655.35 s will become effective. Note: In the default setting, these timer stages are not set to 'Blocked' so that the above links will have no effect. However, should a timer stage in CBF_1 be set to 'Blocked' and should this function later be disabled and de-configured, then the setting 'Blocked' will remain effective as described above.

U-38



Disabling or enabling the CBF function

The activation of the function is enabled at C B F : G e n e r a l e n a b l e U S E R . If this enabling function has been activated, CBF can be disabled or enabled via setting parameters or through appropriately configured binary signal inputs. The front panel HMI and the binary signal inputs have equal priority in this regard. If only the function C B F _ 1 : E n a b l e E X T is assigned to a binary signal input, then CBF will be enabled by a positive edge of the input signal and disabled by a negative edge. If only the parameter C B F _ 1 : D i s a b l e E X T has been assigned to a binary signal input, then a signal at this input will have no effect.

Detecting a CB tripping

A break in current flow is the preferred criterion to detect a successful CB tripping. Protection functions that have triggering criteria not directly dependent on current flow (e.g. V), may additionally be provided with status signals from CB auxiliary contacts for evaluation.

Current flow monitoring

This function is used to detect a break in current flow safely, immediately and pole selectively. The CBF function continuously compares sampled current values from the selected end with the set threshold value C B F : I < . As long as current flow criteria are met the phase-selective signals C B F _ 1 : C u r r e n t f l o w A , C B F _ 1 : C u r r e n t f l o w B , C B F _ 1 : C u r r e n t f l o w C and the multiple signal C B F _ 1 : C u r r e n t f l o w P h x will be continuously issued.

Evaluation of CB status signals

Trip signals included in the general trip command which use status signals provided by the CB auxiliary contacts in addition to current flow monitoring, can be selected with the parameter C B F _ 1 : F c t . a s s i g n m . C B A u x . Applying CB status signals depends on the type of auxiliary contacts available. The P63x can check the following CB status signals for plausibility and evaluate them: The 'Open' signal from the circuit breaker, M A I N : C B o p e n 3 p E X T The 'Closed' signal from the circuit breaker, M A I N : C B x c l o s e d 3 p E X T Note: Each circuit breaker CBx is permanently assigned to the respective CBF_x functions. P631+P632: x = 1, 2; P633: x = 1, 2, 3; P634: x = 1, 2, 3, 4. The evaluation of the CB status signals is blocked, if the configuration of the respective binary signal inputs or the signal levels are not plausible. This will result in the P63x issuing the signal C B F : C B p o s . i m p l a u s i b l e . Evaluation of current criteria is not affected by this blocking. If only one of the two possible CB status signals has been configured, then this configured signal will always be considered plausible by the P63x. As an alternative the status signals from the external device (as of version -620) may be used by the P632 and P633. (See section 2.6.4 'Coupling between control and protection for the CB signals'.) Assigning necessary for this is carried out with the parameters M A I N : S i g . a s g . C B x o p e n or M A I N : S i g . a s g . C B x c l o s e d . Status signals from external devices are processed similar to CB status signals M A I N : C B x o p e n 3 p E X T and M A I N : C B x c l o s e d 3 p E X T . (P632: x = 1, 2; P633: x = 1, 2, 3.)

Startup criteria

The startup of the circuit breaker failure protection function will occur when the CB is recognized as closed during a start criterion. The following startup criteria are evaluated: Internal startup criterion: Generating the specific general trip signal, which has been selected by setting parameter C B F _ 1 : F c t . a s s i g n . s t a r t i n g , is considered a startup criterion. In addition it may be selected, by setting the parameter C B F _ 1 : S t a r t w i t h m a n . t r i p , that a manual trip signal will also be used as a startup criterion. External startup criterion: Triggering by a protection device operating in parallel (C B F _ 1 : S t a r t 3 p E X T ) may be used as a startup criterion. To be on the safe side an additional two pole triggering may be implemented by applying the signal C B F _ 1 : S t a r t e n a b l e E X T . In any case, current flow monitoring is the preferred (primary) monitoring criterion. The CB auxiliary contacts are only evaluated when no current flow is registered and the respective trip signal, included in the general trip command, has been selected from the protection function in parameter C B F _ 1 : F c t . a s s i g n m . C B A u x for the evaluation of the CB auxiliary contacts. Note: With the implementation of software version -611 the startup criterion could disappear when the assigned general trip signal or the external startup criterion dropped out. This happened independently of current flow criteria and CB status signal criteria. The startup criterion has been modified as of software version -620. After a CBF startup has occurred the status of the general trip signal or the external startup signal are now no longer considered. Therefore CBF will drop out only when the current criterion (current flow is below I< in all three phases) is met or when the CB status is identified as open.

Timers and tripping logic

Associated timer stages are started when a startup criterion is met. The signal C B F _ 1 : T r i p s i g n a l t 1 will be issued if the startup criterion is still present when the time delay, set at timer stage C B F _ 1 : t 1 3 p , has elapsed. The output command from this timer stage is intended for a second CB trip coil. The signal C B F _ 1 : T r i p s i g n a l t 2 will be issued if the startup criterion is still present when the time delay, set at timer stage C B F _ 1 : t 2 , has elapsed. The output command from this timer stage is intended for a backup circuit breaker or protection system. These trip signals will be issued as long as the startup criteria are met. Should a loss of gas pressure occur in the explosion chambers of installed type SF6 circuit breakers then all surrounding circuit breakers must be immediately tripped without waiting for a reaction from the damaged switch. In case of an external CB_ 1 fault the elapsing of timer stage t2 may be interrupted by a signal to the binary signal input appropriately configured at C B F _ 1 : C B f a u l t y E X T .

Fault behind CB protection

A fault behind a CB (downstream) is a fault that may occur between a circuit breaker already open and a CT, which is fed from the remote end. Fault behind CB protection recognizes such faults through the current criterion, if the circuit breaker does not provide a signal from its auxiliary contacts that it is closed after the time delay set at C B F _ 1 : D e l a y / f a u l t b e h . C B has elapsed. When such a fault behind CB is recognized the signal C B F _ 1 : F a u l t b e h i n d C B is issued. In such a case the far end circuit breaker may be triggered by an InterMiCOM teleprotection interface. This may also prevent an unwanted triggering of the circuit breaker failure function.

CB synchronization supervision

CB synchronization supervision recognizes states where not all circuit breaker contacts are open or closed. This function uses both current flow monitoring and evaluation of CB status signals to detect CB synchronization. In order to bridge CB operate times the time delay C B F _ 1 : D e l a y / C B s y n c . s u p e r v can be used. When this time delay has elapsed the signal C B F _ 1 : T r i p S i g C B s y n c . s u p e r is issued. Poles that are recognized as being 'open' will still be signaled.

Configurable Function Keys F1 to Fx (general)

If they have not been configured as control keys, function keys F1 to Fx are enabled only after the password for function keys has been entered. Exception: If a function key has been configured at M A I N : L o c a l / R e m o t e k e y the function will only switch from 'Remote' to 'Local' control after the password has been entered, but switching from 'Local' to 'Remote' control will occur without checking the password (see also section 4.3). It is assumed for the remainder of this section that the function key F1 is enabled only after the password (as assigned at F _ K E Y : P a s s w o r d f u n c t . k e y 1 ) has been entered. After the password has been entered the function key will remain active for the time period set at F _ K E Y : R e t u r n t i m e f c t . k e y s . Thereafter, the function key is disabled until the password is entered again. For this example it is further assumed that the password for the function keys is the factory-set password. If the user has changed the password (see the chapter entitled "Changing the Password"), the following description will apply accordingly.

Configurable Function Keys F1 to Fx, particularly as Control Keys (P632, P633 only)

Function keys as control keys, as of version -620 As described in section "Configurable Function Keys (Function Group F_KEY)" in Chapter 3 function keys F1 to Fx may be configured as control keys at F _ K E Y : F c t . a s s i g n m . F x (Fx: F1 to F6). In this case different rules apply to checking the password (see the previous section) and the configuration to 'Key/Switch' is ignored. In case the control functionality is desired then each of the following four control commands, should be assigned to a function key. The particular selection of the four function keys out of the available six, however, does not matter. MAIN: Local/Remote key The 'Local/Remote' control command is effective only in the bay panel except where a binary signal input has been configured for this function. Depending on the functionality set at H M I : F c t . A s s i g n . L / R k e y , the 'Local/Remote' command toggles either between 'Remote' and 'Local' control, or between 'Local/Remote' and 'Local' control. (The parameter H M I : F c t . a s s i g n . L / R k e y may be set either to R L or to R & L L and will then define which of the two switching modes is active.) If the 'Local/Remote' command is configured such that it will switch from 'Remote' control to 'Local' control, then this can only occur if the password has first been entered at H M I : P a s s w o r d L / R . Switching from 'Local' to 'Remote' control will occur without checking the password. (See also section "Configuring the Measured Value Panels and Selection of the Control Point (Function Group HMI)".) MAIN: Device selection key This selection command is effective only in the bay panel and only if 'Local' control is activated. If local control has been selected, pressing the selection key selects the switchgear unit to be controlled. This selected external device is marked on the text display with the flashing symbol ">" in front of the external devices designation text. MAIN: Device OPEN key The 'OPEN' command is effective in the bay panel only. Pressing the key assigned to this function controls the selected switchgear unit taking into account the interlock equation to assume the 'open' status. MAIN: Device CLOSE key The CLOSE command is effective in the bay panel only.
