NOTE!
1. The settings [25.U_Comp] and [25.phi_Comp] are used to compensate the synchro-check voltage, and make the compensated synchro-check voltage is equal to the corresponding protection voltage in normal operation situation.
The settings [25.U_Comp] and [25.phi_Comp] can be set according to following formula.
⎩ ⎨
In general application, the setting [25.U_Comp] is set as “1.000”, and the setting [25.phi_Comp] is set as “0°”.
For example, the synchro-check voltage and the protection are gotten from different sides of a power transformer respectively.
z Synchro-check VT: 400kV Primary, 110V Secondary z Protection VT: 200kV Primary, 100V Secondary z Power transformer: 400kV / 200kV, vector group Yd11
The synchro-check VT supplies 110V secondary rated voltage while the protection VT supplies 100V secondary rated voltage. Therefore, this difference must be balanced:
[25.U_Comp] = 100V / 110V = 0.91
The transformer vector group is defined from the high voltage side to the low voltage side. In this example, the synchro-check voltage is one of the voltages of the high voltage side, i.e. the compensation angle setting is 30° (according to the vector group):
[25.phi_Comp] = 30°
2. The setting [25.Opt_Usyn] is used to select the synchro-check voltage source of the synchronism check element, and this relay can use the corresponding protection voltage for the synchronism check element.
