Completing The Test; Pole Discrepancy Protection Ccrpld (52Pd); Verifying The Settings - ABB Relion 650 Series Commissioning Manual

Section 7
Testing functionality
7.4.4.8

Completing the test

Continue to test another function or end the testing by setting the parameter
Disabled under Main menu/Tests/IED test mode/TESTMODE:1. If another function is tested, then
set the parameter
CCRBRF(50BF)/CCRBRF:X for the function, or for each individual function in a chain, to be tested
next. Remember to set the parameter
tested.
7.4.5

Pole discrepancy protection CCRPLD (52PD)

Prepare the IED for verification of settings as outlined in section
settings.
Values of the logical signals for CCRPLD (52PD) are available on the local HMI under Main menu/
Tests/Function status/Current/CCRPLD(52PD)/CCRPLD:X. The Signal Monitoring in PCM600
shows the same signals that are available on the local HMI.
7.4.5.1

Verifying the settings

1. When CCRPLD (52PD) is set for external, set setting
Settings/IED Settings/Current/CCRPLD/CCRPLD:1 to activate the logic that detects pole
discordance when external pole discordance signaling is used (input EXTPDIND) in the
application configuration.
2. Activate the input EXTPDIND on CCRPLD (52PD) function block, and measure the operating
time of CCRPLD (52PD).
3. Compare the measured time with the set value
4. Reset the EXTPDIND input.
5. When CCRPLD (52PD) is set for unsymmetrical current detection with CB monitoring, set
setting
Enable .
Use the TRIP signal from the configured binary output to stop the timer.
6. Repeat point 4 and 5 using OPENCMD instead of CLOSECMD. Set all three currents to 110%
of
NO TRIP signal should appear due to symmetrical condition.
7.4.5.2 Completing the test
Continue to test another function or end the testing by setting the parameter
Disabled under Main menu/Tests/IED test mode/TESTMODE:1. If another function is tested, then
set the parameter
CCRPLD(52PD)/CCRPLD:X for the function, or for each individual function in a chain, to be tested
next. Remember to set the parameter
tested.
