11.4.11 Pole slip protection PSPPPAM (78)
Prepare the IED for verification of settings as outlined in section
"Preparing for test"
11.4.11.1 Verifying the settings
It is assumed that setting of the pole slip protection function PSPPPAM (78) is done according to
impedances as seen in figure
The test is done by means of injection of three-phase current and three-phase voltage from a
modern test device. This test device shall be able to give voltage and current with the possibility to
change voltage and current amplitude and the angle between the injected voltage and current. The
parameter setting shall be according to the real application chosen values.
Procedure
1. Feed the IED with current and voltage corresponding to a normal operation point
Injected voltage V equal to base voltage (
base current (
2. With maintained amplitude of the injected voltage the current amplitude and angle is
changed to a value ZC/2.
This is done with a speed so that the final impedance is reached after 1 second. As the
injected voltage is higher than 0.92
3. With reduced amplitude of the injected voltage to 0.8
is changed to a value ZC/2.
This is done with a speed so that the final impedance is reached after 1 second. As the
injected voltage is lower than 0.92
4. With reduced amplitude of the injected voltage to 0.8
is changed via ZC/2 to a value corresponding to half
current and voltage.
This is done with a speed so that the final impedance is reached after 1 second. As the
injected voltage is lower than 0.92
to this the signal ZONE1 should be activated.
5. Set
Now the signals TRIP1 and TRIP should be activated.
6. With reduced amplitude of the injected voltage to 0.8
is changed via ZC + (ZA – ZC)/2 to a value corresponding to half
injected current and voltage.
This is done with a speed so that the final impedance is reached after 1s. As the injected
voltage is lower than 0.92
the signal ZONE2 should be activated.
7. Set
Now the signals TRIP2 and TRIP should be activated.
