Figure 47: Receiving line voltage for synchrocheck functionality using SMV
If only one phase (UL1) is connected between SMVRCV and
ULTVTR2, then VT connection parameter of the ULTVTR2 function
block needs to be set to “UL1” in the Parameter Setting tool in
PCM600 before writing the configuration to the IED.
ALARM and WARNING outputs are active during the configuration
writing. If VT connection type is set incorrectly, ULTVTR ALARM
and WARNING outputs are always active. In case of unsupported
configuration, SMV error is indicated.
The
WARNING output of TxTR should be connected in the SMV applications to
perform the necessary actions in case the SMV angle information is out of the
accuracy range. Depending on the protection function operation principle, inaccurate
angle information is also seen in the related protection function operation inaccuracy.
Additionally, the ALARM output of TxTR should be connected to ensure fail-safe
operation in all circumstances. The WARNING output is always internally active
whenever the ALARM output is active.
WARNING and ALARM information is internally propagated for the measurement
functions. Thus, measurement functions are able to update the measured value quality
information accordingly without any additional connections.
