Abstract

An exemplary system and method for detecting an islanding condition are provided. The system includes a converter system for converting input power from a power source and providing output power and a converter controller for regulating active and reactive power components of the output power. The converter controller includes an anti-islanding protection module for performing the steps of generating an anti- islanding disturbance signal and a disturbance compensation signal based on at least one measured electrical value of the output value; separately applying the anti- islanding disturbance signal and the disturbance compensation signal to adjust either or both of the active and reactive power components to drive the at least one measured electrical value outside of a nominal range upon the occurrence of an islanding condition; and detecting the islanding condition.
