Abstract
Generators 12a are for a distributed generation system. A control system 32a receives information about network faults 14a. In normal conditions, the control system 32a controls the field current in the field coils of the generator 12a, to maintain generator output voltage at the rated value. At the onset of fault conditions, the control system 32a changes the manner in which field current is controlled, in order to reduce the fault current put onto the network.
