17 1MRK UEN Section 2 Overview 2.3 Signals Bay / Station Protection à function overlapping signals Signal designations The BP/ SP function overlapping (general) signals correspond to the signal numbers nomenclature of the station protection system (for details see Technical Manual REB500) Example: 19205_Block BP (5 digit signal number) Outputs generated by BP and used as SP inputs (default signals) Table 5 BU_ BP outputs to SP inputs (default signals) Signal 11120_BP External TRIP 11125_BP External TRIP BB zone 13210_BP Block BFP 13610_BP Trip transfer 13761_BP Start BFP L1L2L3_5 Description This is the tripping signal generated by bay protection of REB500. It trips faults on a line with the aid of the REB500 tripping contact. Tripping thus takes account of the busbar configuration at the time. The signal is activated by the bay protection directly and does not therefore appear as binary input signal. This is a tripping signal generated by the bay protection of REB500 which is used to trip the entire bus zone to which the fbay is connected. The tripping command is applied to all the bay units of the bus zone and sections of busbars interconnected by an isolator (intertripping). This signal is directly activated by the bay protection and doesn t therefore appear as a binary input signal. The operation of the breaker failure protection of the corresponding feeder is blocked. When the blocking signal is cancelled and providing a starting signal is present and current is flowing, the timers start again at t = 0. Reserved for the special application trip transfer. This signal is directly activated by the bay protection unit and does not therefore appear as a binary input signal. This signal is functionally identical to signal "13760_Start BFP L1L2L3_5", but it is directly activated by the bay protection and does not therefore appear as a binary input signal _BP Start BFP Lp Breaker failure protection with phase-selective starting (p = 1, 2 or 3). The breaker failure protection timer starts when this signal is activated by BP functions and the BFP measures a current in the corresponding phase. This signal is directly activated by the bay protection and does not therefore appear as a binary input signal _BP Start BFP L1L2L3 Breaker failure protection with three-phase starting. The breaker failure protection timer starts when this signal is activated and the BFP measures a current in any phase. This signal is directly activated by the bay protection and does not therefore appear as a binary input signal. Application Manual 9

18 Section 2 Overview 1MRK UEN Signal 13790_BP External start BFP 13797_BP Start BFP L _BP Global Start DR Description Breaker failure protection with three-phase starting. The breaker failure protection timer starts when this signal is activated regardless of the current measurement. This signal is directly activated by the bay protection and does not therefore appear as a binary input signal. Breaker failure protection with L0 - starting. The breaker failure protection timer starts when this signal is activated by BP functions and the BFP measures a current in the neutral system. This signal is directly activated by the bay protection and does not therefore appear as a binary input signal. Starts those disturbance recorders in the bay units that are configured. The signal Central start DR in the bay units must be configured. This signal is directly activated by the BP unit and does not therefore appear as a binary input signal General inputs to BP Table 6 BU_ Inputs to BP Signal 19205_Block BP 19600_Activation BP ParSet_ _Activation BP ParSet_ _Activation BP ParSet_ _Activation BP ParSet_4 Description The BP output signals of the respective bay unit are blocked.

Assigning protection functions to parameter sets Every instance of a protection function can be assigned to a particular parameter set. The REB500 runs the protection functions in the currently selected parameter set. The active parameter set is changed by setting the appropriate binary input on the bay unit. Figure 5 Parameter set assignment To assign the instance of a protection function to a parameter set, simply check the corresponding box using the left mouse button. Using the context menu To open the context menu for a particular protection function, first select the function by clicking the left mouse button on its symbol and then clicking the right mouse button. Figure 6 Table 38 Menu item Copy Content menu Content menu dialogues Description Creates a copy of the protection function according to the following rules: A copy cannot be in the same parameter set as the original. The input signals of a copy are the same as those of the original and cannot be changed. Only defined parameters of a copy can be configured. All other parameters are taken from the original.

30 Section 3 Configuring bay protection using HMI500 1MRK UEN Menu item Delete Description The instance of the specific protection function is deleted together with all the settings that the user has made up to that point. If the function being deleted has connections to other protection functions, an error message appears instructing you to first delete the connections. Properties Thus an instance can only be deleted after all its interconnections have been deleted. This opens a dialog with all the function s settings. Double clicking on the function s symbol opens the same dialog. Status indicator On the left of each instance number and function symbol there is a status indicator which signals the validity of the parameters entered. Figure 7 Status indication of BP Function Green indicates that the configuration is correct and valid while red indicates that the setting procedure has not been completed. This generally means in the case of a single-phase function that an analog channel has not yet been assigned to it.

32 Section 3 Configuring bay protection using HMI500 1MRK UEN In the dialogs for setting protection functions, a binary input is described in plain text and has a button for configuration. Figure 10 Setting binary input signal e.g. OCDT Blocking input The following signals can be assigned to the binary inputs of each BP function: BP internal outputs from an another BP function (see ) General inputs to BP (see ) Signal status Always FALSE or Always TRUE BP external (see ) Binary input signals (from optocoupler inputs) Predefined outputs of a station protection function 24 Application Manual

33 1MRK UEN Section 3 Configuring bay protection using HMI Assignment of BP internal input signals Click the left mouse button on the status button of the desired signal to open the dialog Select Binary Input for configuring the status of the particular binary input signal. The dialog has two tabs, the first of which ( TRUE / FALSE ) provides facility for setting the input status to Always True, OR Always False. This is a permanent assignment, without the involvement of an output signal of another function. Figure 11 Configuring binary inputs (TRUE / FALSE) The second tab Output from Function enables the output of an existing instance of a protection function to be connected to the particular signal input. The Output from Function tab lists all the protection function instances set for the particular bay unit together with the unique number of the instance. Upon selecting a protection function in the list on the left by clicking the left mouse button on it, its binary output signals appear on the right of the dialog. Application Manual 25

35 1MRK UEN Section 3 Configuring bay protection using HMI500 Default The Default tab lists station protection default outputs (see Figure 13). Any binary input of a BP function can be linked to these to enable the exchange of signals between station protection and the bay protection sections (e.g. signal 21105_External TRIP). Figure 13 Configuring binary inputs ( Default à Output from SP function) Location of input signals from SP function within the BP function diagram see Figure 1, Label No. 15. General Purpose The General Purpose tab provides facility for defining up to 20 user signals. To this end, select a signal number with the left mouse button. A text field appears in which the user can write a signal name (see Figure 14). The signal name entered must conform to REB500 signal conventions (see Section ). The Section provides a list of all signals available for General Purpose inputs. Application Manual 27

37 1MRK UEN Section 3 Configuring bay protection using HMI Configuring binary output signals Each REB500 bay protection function has a defined number of binary output signals. These are described for each of the protection functions in Section In the dialogs for setting protection functions, a binary output signal is described in plain text and has a field, which lists the input signals assigned to the respective output. Figure 15 BP output signal assignment The list shows the input signals assigned to the respective output. For each signal in the list, the instance number and an abbreviation of the function are given. Table 42 BP output signal assignment Example Description 09 Instance of BP function OR Symbol representing the BP function of the instance Binary Inp 2 Binary input 2 of OR function Output signals are assigned when configuring either the binary output function (see Section ) or bay protection input signal function (see Section ) Exception: Binary output function The binary output function has to be included in all sets of parameters and that is why the function is automatically selected for all of them and the setting cannot be changed by the user. Figure 16 Parameter set assignment of BP outputs (fixed allocation) Application Manual 29

38 Section 3 Configuring bay protection using HMI500 1MRK UEN The configuration of the binary output function is basically the same as for the other protection functions. Open the configuration dialog by double clicking with the left mouse button on the symbol or via the context menu. The signals of the binary output function are divided into two groups for Default and General purpose outputs. Default The default groups are signals which are exchanged between bay and station protection functions (e.g. distance protection trip for starting the breaker failure protection). The station protection input signals (see Table 5) are all predefined and can t be changed. Choice of the bay protection output signals ( General Purpose, see Figure 18), on the other hand, is unrestricted. Figure 17 BP output (Default) The signals assigned under the default group do not reduce the number of BP output channels (total of 120). Location of BP default output signals within the BP function diagram see Figure 1, Label No Application Manual

39 1MRK UEN Section 3 Configuring bay protection using HMI500 General Purpose The General Purpose tab provides facility for defining up to 120 output signals. Figure 18 BP output (General purpose) Location of BP general purpose output signals within the BP function diagram see Figure 1, Label No. 12. Edit (used for both Default and General purpose signals Click on the respective Edit button to assign a Default or General purpose signal. This opens the dialog Select binary input. The remaining procedure is the same as described for binary input signals (see Section ). Only bay protection output signals that are configured to a BP Output Channel can be assigned to an output relay of the bay unit by selecting the menu Configuration/ Binary module/ Outputs. Section provides a list of available bay protection output signals. Location of Binary module output signals within the BP function diagram see Figure 1, Label No. 13. Application Manual 31

40 Section 3 Configuring bay protection using HMI500 1MRK UEN Recording a binary signal as an event Only bay protection binary signals can be configured to be recorded as events that are also configured via menu Configuration/ Binary module (output signals do not necessarily have to be assigned to output relays) Disturbance recording of a binary signal Binary output signals generated by bay protection functions can be configured for disturbance recording, providing they are configured in the General purpose dialog for the binary output function (see Figure 18). Binary input signals of the bay protection functions can be configured for disturbance recording, providing they are configured in the General purpose dialog for the binary input function (see Figure 14) and also as a binary input via the HMI500 menu Configuration/Binary module/inputs menu. 3.5 Protection function settings The appropriate dialog for setting a protection function is opened by double clicking the left mouse button on the respective symbol or via the context menu. Figure 19 Protection function settings The settings in the dialog for each protection function are described in detail in Section Application Manual
