Testing the voltage difference
Set the voltage difference to 0.15 p.u. on the local HMI, and the test should check that
operation is achieved when the voltage difference VDiffSC is lower than 0.15 p.u.
The settings used in the test shall be final settings. The test shall be adapted to site setting
values instead of values in the example below.
Test with no voltage difference between the inputs.
Test with a voltage difference higher than the set VDiffSC.
1. Apply voltages V-Line (for example) = 80% GblBaseSelLine and V-Bus = 80%
GblBaseSelBus
2. Check that the AUTOSYOK and MANSYOK outputs are activated.
3. The test can be repeated with different voltage values to verify that the function
operates within the set VDiffSC. Check with both V-Line and V-Bus respectively
lower than the other.
4. Increase the V-Bus to 110% GblBaseSelBus, and the V-Line = 90% GblBaseSelLine
and also the opposite condition.
5. Check that the two outputs for manual and auto synchronism are not activated.
Testing the phase angle difference
The phase angle differences PhaseDiffM and PhaseDiffA respectively are set to their final
settings and the test should verify that operation is achieved when the phase angle
difference is lower than this value both leading and lagging.
Test with no voltage difference.
1. Apply voltages V-Line (for example) = 100% GblBaseSelLine and V-Bus = 100%
GblBaseSelBus, with a phase difference equal to 0 degrees and a frequency
difference lower than FreqDiffA and FreqDiffM.
2. Check that the AUTOSYOK and MANSYOK outputs are activated.
The test can be repeated with other phase difference values to verify that the function
operates for values lower than the set ones, PhaseDiffM and PhaseDiffA. By
changing the phase angle on the voltage connected to V-Bus, between ± degrees,
the user can check that the two outputs are activated for a phase difference lower than
the set value. It should not operate for other values. See figure
16.
