摘　　要：通过对孤岛效应和检测盲区的分析,以分布式发电系统中基于逆变器侧的各种检测方法为主,按照其检测思路,从被动检测和主动检测两个方面进行分类归纳。对各种检测方法的检测原理、优缺点以及一些检测方法的改进方案进行综合评述,根据具体的功率的匹配程度和电能质量等要求,来选择将适合的检测方法相结合,充分发挥各自检测方法的优点,才能达到最优的检测目的。而微网由并网向孤岛的过渡以及微网孤岛运行的利用也将是未来的研究重点。Through analzying the islanding and non-detection zone and focusing on various islanding detection methods based on the inverter-side in distributed power generation systems,these islanding detection techniques can broadly be divided into passive detection and active detection.The detertion theory,advantages and disadvantages and the improved schemes of several detection methods are evaluated comprenhensively.According to the degree of the power match and the requirement of the power quality,the appropriate combination of detection methods can be selected.In this way,the best detection result can be achieved by exploiting the advantage of each method.The future research will focus on the transition from interconnected to islanding and application of islanding operation in microgrid.
