摘　　要：从孤岛效应产生的危害出发,分析了孤岛发生的可能性与危险性,概述了国内外的孤岛检测指标。在对孤岛效应原理进行数学分析的基础上,对孤岛检测的方法进行了分类和对比,使得用户可根据实际工程需求自主选择主动检测或被动检测的孤岛检测方法。通过Simulink对光伏孤岛系统进行仿真,证明孤岛效应检测的原理和必要性,为孤岛效应检测方法的改进提供了理论基础。The possibilities and dangers of islands occurred were analyzed from the harm of islanding. The principle islanding was carded out in mathematical analysis. The islanding detection indexes were summarized both at home and abroad. In order to make users choose active or passive detection in the actual engineering applications, the islanding detection methods were classified and contrast. According to simulation of PV islanding system with Simulink, the principle and necessity of islanding detection were proved and a theoretical basis in improving the method of islanding detection was provided.
