Testing the frequency difference
M2377-232 v9
The frequency difference test should verify that operation is achieved when the
FreqDiffA and FreqDiffM frequency difference is lower than the set value for
manual and auto synchronizing check, FreqDiffA and FreqDiffM respectively and
that operation is blocked when the frequency difference is greater.
Test with frequency difference = 0 mHz
Test with a frequency difference outside the set limits for manual and auto
synchronizing check respectively.
1. Apply voltages U-Line equal to 100% GblBaseSelLine and U-Bus equal to
100% GblBaseSelBus , with a frequency difference equal to 0 mHz and a
phase difference lower than the set value.
2. Check that the AUTOSYOK and MANSYOK outputs are activated.
3. Apply voltage to the U-Line equal to 100% GblBaseSelLine with a frequency
equal to 50 Hz and voltage U-Bus equal to 100% GblBaseSelBus , with a
frequency outside the set limit.
4. Check that the two outputs are not activated. The test can be repeated with
different frequency values to verify that the function operates for values lower
than the set ones. If a modern test set is used, the frequency can be changed
continuously.
Testing the reference voltage
M2377-249 v5
1. Use the same basic test connection as in figure 12 .
The voltage difference between the voltage connected to U-Bus and U-Line
should be 0%, so that the AUTOSYOK and MANSYOK outputs are activated
first.
2. Change the U-Line voltage connection to U-Line2 without changing the
setting on the local HMI. Check that the two outputs are not activated.
9.5.1.3 Testing the energizing check
M2377-262 v6
During the test of the energizing check function for a single bay arrangement, these
voltage inputs are used:
U-Line UL1, UL2 or UL3 line1 voltage inputs on the IED
U-Bus Bus voltage input on the IED
General
M2377-271 v6
When testing the energizing check function for the applicable bus, arrangement
shall be done for the energizing check functions. The voltage is selected by
activation of different inputs in the voltage selection logic.
Live voltage level is fixed to 80% UBase and dead voltage level to fixed 40%
UBase .
