11.4.9 Power swing detection ZMRPSB (68)
Prepare the IED for verification of settings outlined in Section
settings".
Values of the logical signals for ZMRPSB are available on the local HMI under Main menu/Test/
Function status/Impedance protection/PowerSwingDetection(68,Zpsb)/ZMRPSB(68;Zpsb):1
The Signal Monitoring tool in PCM600 shows same signals that are available on the local HMI.
11.4.9.1 Verifying the signal and settings
Measure the operating characteristics during constant current conditions. Keep the measured
current as close as possible to the rated value of the IED or lower. Ensure that it is higher than the
set minimum operating current.
Ensure that the maximum continuous current to the IED does not exceed four times of its rated
value, if the measurement of the operating characteristics runs under constant voltage conditions.
The test is mainly divided into two parts, one aim is to verify that the settings are in accordance
with the selectivity plan and another aim is to verify the operation of ZMRPSB.
Before starting this testing process, all impedance measuring zones shall be set and in operation.
Ensure that the inner zone of ZMRPSB must cover all impedance measuring zones that are set for
operation.
Test of the interactions or combinations that are not configured are not considered in this
instruction.
Always set
Testing the operating characteristics
Preconditions
The following output signals shall be configured to binary output available:
impedance within outer impedance boundary and
impedance boundary.
1. Set
to values that are in accordance with the selectivity plan and the corresponding operating
characteristic is as shown in Figure 37.
2. Set
3. The test points that are to be considered for the measurement accuracy of set resistive and
reactive reaches for outer and inner boundaries are shown in Figure 37, Table
