Abstract
Islanding is a special type of open circuit fault where the distributed resource continues to feed local loads during loss of mains situation. This paper develops a technique to detect islanding in a six bus power system. The input to the technique is dependent on synchrophasor measurement. The decision made in the technique is based on IEC62116 standards and predefined threshold and of current phasors. Synchrophasor based islanding detection can be considered as communication based islanding detection where measurements from both islanded region and grid connected region are utilized for islanding detection. PMU based islanding detection is highly recommended to predetermine cascading line outage and to check voltage profile of islanded region.
