ABB REQ650 User Manual

10.4.4.1 Switch controller (SCSWI)
The parameter CtlModel specifies the type of control model according to IEC 61850.
For normal control of circuit breakers, disconnectors and earthing switches the control
model is set to SBO Enh (Select-Before-Operate) with enhanced security.
When the operation shall be performed in one step, the model direct control with
normal security is used.
At control with enhanced security there is an additional supervision of the status value
by the control object, which means that each command sequence must be terminated
by a termination command.
The parameter PosDependent gives permission to operate depending on the position
indication, that is, at Always permitted it is always permitted to operate independent
of the value of the position. At Not perm at 00/11 it is not permitted to operate if the
position is in bad or intermediate state.
tSelect is the maximum time between the select and the execute command signal, that
is, the time the operator has to perform the command execution after the selection of
the object to operate. When the time has expired, the selected output signal is set to
false and a cause-code is given over IEC 61850.
tSynchrocheck is the allowed time for the synchrocheck function to fulfill the close
conditions. When the time has expired, the control function is reset.
The timer tSynchronizing supervises that the signal synchronizing in progress is
obtained in SCSWI after start of the synchronizing function. The start signal for the
synchronizing is obtained if the synchrocheck conditions are not fulfilled. When the
time has expired, the control function is reset. If no synchronizing function is
included, the time is set to 0, which means no start of the synchronizing function.
tExecutionFB is the maximum time between the execute command signal and the
command termination. When the time has expired, the control function is reset.
10.4.4.2 Bay control (QCBAY)
If the parameter AllPSTOValid is set to No priority, all originators from local and
remote are accepted without any priority.
