Good evening,
We have a power plant with six diesel-fuel generators. The AVRs are UNITROL 1000 from ABB. The grid has an excess of reactive power produced by the underground cables. The AVRs are in voltage regulation mode. During the night the load is quite small and the voltage goes up. The AVRs reduce the generation of reactive power and sometimes start taking it in.
I'm worried to have the reactive power being supplied by the grid.
If there is a fault on the grid that makes the voltage decay significantly, are the AVRs capable to change immediately from taking in to generating reactive power?
What about the ancillary services of the power plant? Will the motors and transformers, supplied by the grid reactive power, stop working because of a voltage collapse?
I need your help to know if I should be concerned of a power plant taking in reactive power from the grid.
Best regards.
