15.2.3.1 Bay control (QCBAY)
If the parameter AllPSTOValid is set to No priority, all originators from local and
remote are accepted without any priority.
If the parameter RemoteIncStation is set to Yes, commands from IEC 61850-8-1
clients at both station and remote level are accepted, when the QCBAY function is in
Remote. If set to No, the command LocSta controls which operator place is accepted
when QCBAY is in Remote. If LocSta is true, only commands from station level are
accepted, otherwise only commands from remote level are accepted.
The parameter RemoteIncStation has only effect on the IEC
61850-8-1 communication. Further, when using IEC 61850 edition 1
communication, the parameter should be set to Yes, since the
command LocSta is not defined in IEC 61850-8-1 edition 1.
15.2.3.2 Switch controller (SCSWI)
The parameter CtlModel specifies the type of control model according to IEC 61850.
The default for 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, and no monitoring of the result of
the command is desired, 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 allowed 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.
The time parameter tResResponse is the allowed time from reservation request to the
feedback reservation granted from all bays involved in the reservation function. When
the time has expired, the control function is reset, and a cause-code is given.
tSynchrocheck is the allowed time for the synchrocheck function to fulfill the close
conditions. When the time has expired, the function tries to start the synchronizing
function. If tSynchrocheck is set to 0, no synchrocheck is done, before starting the
synchronizing function.
