Abstract

A distributed generation unit for connection to an electric power distribution grid also energised by utility company generation, comprising an anti-islanding system arranged to detect outage of utility generation from the grid by reference to a harmonic or harmonics generated by the distributed generation unit, and to disconnect the distributed generation unit from the grid in the event of a utility outage.
