2.8 Disconnector control
Default configuration REC 561
The time for cyclic sending of data between control terminals is set to 20 s
for the event functon blocks. The interval time, in corresponding com-
mand function blocks for receiving of data, is set a little bit longer — 21 s
in this configuration — to supervise the communication.
The reservation function within the own bay is configured in the
BAY_RE worksheet. The solution follows the principle of reservation in
Apparatus Control (1MRK 580 150-XEN).
The BAY_CON worksheet contains the bay-oriented, control functions
including blocking and interlocking functions. To create the abnormal sta-
tus signal, connect all corresponding signals together via an OR gate.
Here, the VOLT_OP and VOLT_CL input signals are set to FALSE and
TRUE, which means that the line voltage is not considered in the inter-
locking function. You can use the logic in this configuration to consider
the voltage value by connecting the limit-supervision block for the ano-
logue inputs and the fuse failure supervision. These functions are options
and are not included in this default configuration.
The configuration of circuit breaker control is made according to the
Q0_CON worksheet. It is configured for use with external synchro-check,
which means use of SWICONB. To use the optional internal synchro-
check function, some modifications must be made according to Apparatus
Control (1MRK 580 150-XEN), which also describes the connections to
other options, for example, autoreclosing. Trip signals from optional pro-
tection functions are connected via the tripping logic. All breaker specific
indications, events and commands between the terminal and the station
MMI and/or the remote gateway are configured in this worksheet.
In the Event function block for transferring of signals to the station MMI,
the suppression times for displaying and event handling of the breaker
position are set to one second to avoid presentation of middle position.
There is one worksheet for each disconnector. The designations of the
worksheets are Q1_CON, Q2_CON and Q9_CON. The configuration is
made in the same way as for the breaker—without the possibilities to con-
nect synchro-check, autoreclosing, and trip signals.
In the Event function block for transferring of signals to the station MMI,
the suppression time for displaying the disconnector position is set to zero
to display the middle position. The suppression time for the event han-
dling of the disconnector position is set to 10 seconds—to avoid events
during the normal run of the disconnector.
