11.5.12 Directional overpower protection GOPPDOP (32)
Prepare the IED for verification of settings as outlined in section
section "Preparing for test"
11.5.12.1 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.
2. Adjust the injected current and voltage to the set rated values in % of
(converted to secondary current and voltage). The angle between the injected current and
voltage shall be set equal to the set direction
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
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
current slowly from 0 until the PICKUP1 signal, pickup of stage 1, is activated. Check the
injected power and compare it to the set value
Sbase .
