One of the most important methods in the field of anti islanding protection of wind turbine is rate of change of frequency (ROCOF). When a self-excitation induction generator is islanded, voltage and frequency will vary and in most cases, exceed from legal range that can be detected by voltage relays, frequency relays and ROCOF relays. In this paper ROCOF relay performance in case of induction generator is studied. However there are some condition called non detection zone that cause voltage… CONTINUE READING
