摘　　要：反孤岛效应检测(Anti-islanding)是分布式发电系统并网时必须具备的功能。文章分析了孤岛检测的基本原理。同时总结了孤岛检测的各种方法,其中包括远程监控和本地检测,而本地检测的方法又可分为主动检测和被动检测。最后分析了各种方案的特点及适用场合。Anti-islanding is safety critical issue in DG system including grid-connected AC inverters. In this paper,the basic theory of AI is analyzed, and recent developments in AI techniques is review. The techniques may be classified as remote and local. Local techniques may further be classified as passive and active. Further more, the characteristic of every kind of AI schemes is also be given.
