The invention provides an island recognition method of distribution network, which is mainly suitable for the active distribution network adopting the main network with small grounding resistance and using the earth-free distributed power resource. Then the island detection is processed through testing the zero-sequence voltage changes of the grid entry points, also named PPC points, of the distributed power resource. The island recognition method of distribution network has the advantages that the blind zone becomes smaller and the position with the single-phase-to-ground fault can be determined quickly by the island recognition method of distribution network, according to the zero-sequence voltage changes of the PPC points, whether the voltage amplitude of the PPC points is in the preset range or not.
