Claim 14:
15. The system of claim 14, further comprising filtering and analyzing the reactive power command signal issued by the farm-level controller, wherein filtering the reactive power command signal issued by the farm-level controller further comprises filtering the reactive power command signal issued by the farm-level controller via a plurality of wash-out filters and a lag filter, and wherein analyzing the reactive power command signal issued by the farm-level controller further comprises:
determining a magnitude of the filtered reactive power command signal;
amplifying the magnitude of the filtered reactive power command signal; and
comparing the amplified magnitude of the reactive power command signal to a magnitude threshold,
wherein, when the amplified magnitude of the filtered reactive power command signal exceeds the magnitude threshold, starting a counter for counting a number of times the amplified magnitude crosses zero within a certain time period.
