摘要：Distributed generators (DG) present in the electrical power system may continue to supply the local area even in the case when the main grid gets disconnected, this is called islanding. Such islanded operation may result into serious safety hazards to the personnel and the equipment as the power lines which are presumed to be disconnected are still energized by nearby distributed generators. The issue is still more critical when large number of DGs are interfaced through power electronic converters having short overload operating capability. Hence, it is indispensable to identify such islanding condition and to prevent DGs from energizing the lines. This paper presents the over view of different islanding detection techniques for DG. Comparison of these techniques is also provided in the paper.
