Synchrophasor based islanding detection method

Unintentional islanding is one of the most disturbing issues of distributed generation. It has serious consequences for electricity and it poses a threat to life and health of the personnel. This paper makes a comparison between two islanding detection methods. The first method is the well known over/under voltage and over/under frequency passive method. The second method is a synchrophasor based method. The simulations proved that the two studied methods have a good performance for parallel RLC.
