Control
10.2.4.1 Switch controller (SCSWI)
The parameter
control of circuit breakers, disconnectors and grounding switches the control model is set to
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
that is, at
position. At
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 synchronism check function to fulfill the close
conditions. When the time has expired, the control function is reset.
The timer
SCSWI after start of the synchronizing function. The start signal for the synchronizing is obtained
if the synchronism check 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.
10.2.4.2 Switch (SXCBR/SXSWI)
tStartMove is the supervision time for the apparatus to start moving after a command execution.
When the time has expired, the switch function is reset.
During the
state. When the time has expired, the switch function is reset. The indication of the mid-position
at SCSWI is suppressed during this time period when the position changes from open to close or
vice-versa.
If the parameter
correct end position is reached. If the parameter is set to
remains active until the timer
tOpenPulse is the output pulse length for an open command. The default length is set to 200 ms
for a circuit breaker (SXCBR) and 200 ms for a disconnector or grounding switch (SXSWI).
tClosePulse is the output pulse length for a close command. The default length is set to 200 ms for
a circuit breaker (SXCBR) and 200 ms for a disconnector or grounding switch (SXSWI).
SuppressMidPos when Enabled will suppress the mid-position during the time tIntermediate .
