Abstract

This paper provides an analysis of the performance of the under/over frequency and under/over voltage relays for islanding detection of squirrel-cage induction generators. This analysis is based on the nondetection zones, which are determined by extensive dynamic simulations using PSCAD/EMTDC. The presented nondetection zones are constructed considering different reactive power compensation and different detection times. Analysis on the nondetection zones is developed, and the influence of the required detection time and of the reactive power compensation on the nondetection zone is highlighted.
