Islanding in a gird connected inverter of wind power generation system may give a bad effect on equipments or yield safety hazards on grid so it should be detected rapidly and exactly. Passive methods are simple to detect islanding by monitoring parameters of system but it has non detection zone (NDZ). Active methods are more effective to detect islanding by injecting small disturbance into output of utility interactive inverter. This paper proposes a novel hybrid anti-islanding detection method, which combines the conventional passive over/under voltage and over/under frequency (OUV-OUF) method with a new active harmonic injection method. In the proposed scheme, the active methods can be used effectively to overcome the problem caused by the NDZ. When NDZ does not exist, the passive methods can detect the islanding rapidly. The effectiveness of the proposed scheme is proved through comparative simulation results.
