Abstract :
Investigations show that reactive power mismatch affects frequency relays performances. Vector surge relays (VSRs) being frequency based relays are widely used for islanding detection in power systems. Considering similarities between frequency relays´(FRs´) and VSRs´ performances, it is suggested that FRs can detect islanding conditions as well as VSRs, however no evidence is presented for comparing FR and VSR performances in case of reactive power mismatch. This paper presents a comparison of FR and VSR islanding detection protection performances considering reactive power mismatch. The results confirm the validity of replacing VSRs with FRs.
