Values of the logical signals for GOPPDOP are available on the local HMI under
Main menu/Tests/Function status/Current/GOPPDOP(32,P>)/GOPPDOP:X.
The Signal Monitoring in PCM600 shows the same signals that are available on the
local HMI.

Verifying the settings

The overpower protection shall be set to values according to the real set values to be
used. The test is made by means of injection of voltage and current where the
amplitude of both current and voltage and the phase angle between the voltage and
current can be controlled. During the test the analog outputs of active and reactive
power shall be monitored.
1. Connect the test set for injection of voltage and current corresponding to the
mode to be used in the application. If a three phase test set is available this could
be used for all the modes. If a single phase current/voltage test set is available the
test set should be connected to a selected input for one phase current and voltage.
Use the formulas stated in
set mode Mode can be found under Main menu/Settings/IED Settings/
Current/GOPPDOP(32,P>)/GOPPDOP:1/General.
2. Adjust the injected current and voltage to the set rated values in % of IBase and
UBase (converted to secondary current and voltage). The angle between the
injected current and voltage shall be set equal to the set direction Angle1, angle
for stage 1 (equal to 0° for low forward power protection and equal to 180° for
reverse power protection). Check that the monitored active power is equal to
100% of rated power and that the reactive power is equal to 0% of rated power.
3. Change the angle between the injected current and voltage to Angle1 + 90°.
Check that the monitored active power is equal to 0% of rated power and that the
reactive power is equal to 100% of rated power.
4. Change the angle between the injected current and voltage back to Angle1 value.
Increase the current slowly from 0 until the START1 signal, start of stage 1, is
activated. Check the injected power and compare it to the set value Power1,
power setting for stage 1 in % of Sbase.
5. Increase the current to 100% of IBase and switch the current off.
6. Switch the current on and measure the time for activation of TRIP1, trip of stage
1.
7. If a second stage is used, repeat steps

Completing the test

Continue to test another function or end the testing by setting the parameter TestMode
to Off under Main menu/Tests/IED test mode/TESTMODE:1. If another function
is tested, then set the parameter Blocked to No under Main menu/Tests/Function test
modes/Current/GOPPDOP(32,P>)/GOPPDOP:X for the function, or for each
individual function in a chain, to be tested next. Remember to set the parameter
Blocked to Yes, for each individual function that has been tested.

2 to 6 for the second stage.
