6.9 Testing control functions
During periods of frequent counter state/value changes, if the
auxiliary power to the IED is interrupted, it is possible that this
information will be lost.
6.9.1 Synchrocheck, energizing check, and synchronizing
SESRSYN
This section contains instructions on how to test the synchrocheck, energizing check,
and synchronizing function SESRSYN for single, double and 1½ breaker
arrangements.
This section contains instructions on how to test the synchrocheck and energizing
check for single CB with or without the synchronizing function.
Prepare the IED for verification of settings as outlined in 5.1 "Preparing the IED to
verify settings" .
Values of the logical signals for SESRSYN are available on the local HMI under Main
menu/Tests/Function status/Control/SESRSYN(25,SYNC)/SESRSYN:X . The
Signal Monitoring in PCM600 shows the same signals that are available on the local
HMI.
At commissioning and periodical checks, the functions shall be tested with the used
settings. To test a specific function, it might be necessary to change some setting
parameters, for example:
• AutoEnerg = Off / DLLB / DBLL / Both
• ManEnerg = Off
• Operation = Off / On
• Activation of the voltage selection function if applicable
The tests explained in the test procedures below describe the settings, which can be
used as references during testing before the final settings are specified. After testing,
restore the equipment to the normal or desired settings.
A secondary injection test set with the possibility to alter the phase angle and
amplitude of the voltage is needed. The test set must also be able to generate different
frequencies on different outputs.
The description below applies for a system with a nominal frequency
of 50 Hz but can be directly applicable to 60 Hz. SESRSYN can be set
to use different phases, phase to earth or phase to phase. Use the set
voltages instead of what is indicated below.
