Islanding is a condition where a distributed generator continues to power a region, even though electrical grid power is no longer present. Islanding can be dangerous to utility workers, and to equipment. In order to minimise risk, it is important to decrease the time in which an island is detected. One method for achieving this is to measure rate of change of frequency ROCOF, and to look for exceptional deviations.
