6.5.9 Accidental energizing protection for synchronous generator
AEGGAPC
Prepare the IED for verification of settings as outlined in 5.1 "Preparing the IED to
verify settings" .
Values of the logical signals for AEGGAPC are available on the local HMI under
Main menu/Tests/Function status/Current/AEGGAPC(50AE,U<&I>)/
AEGGAPC:1
. The Signal Monitoring in PCM600 shows the same signals that are
available on the local HMI.
6.5.9.1 Verifying the settings
1. Connect the test set for three-phase current injection and for three phase voltage
injection to the appropriate IED terminals.
2. Inject zero voltage to the IED.
3. Increase the injected symmetric three phase current slowly and note the operated
value (start value).
4. Decrease the current slowly and note the reset value.
5. Connect a trip output contact to a timer.
6. Set the injected current to 200% of the operate level, switch on the current and
check the time delay.
7. Check that all trip and start contacts operate according to the configuration
(signal matrises).
8. Finally check that start and trip information is stored in the event menu.
9. Inject rated symmetric three phase voltage to the IED.
10. Set the injected current to 200% of the operate level, switch on the current. The
function shall not start and trip.
11. Inject 95% of the set ArmU< value symmetric three-phase voltage to the IED.
12. Set the injected current to 200% of the operate level, switch on the current. The
function shall start and trip.
6.5.10 Negative-sequence time overcurrent protection for machines
NS2PTOC
Prepare the IED for verification of settings as outlined in 5.1 "Preparing the IED to
verify settings" .
Values of the logical signals for NS2PTOC are available on the local HMI under Main
menu/Tests/Function status/Current/NS2PTOC(46I2,2I2>)/NS2PTOC:1 . The
Signal Monitoring in PCM600 shows the same signals that are available on the local
HMI.
