摘　　要：针对分布式发电系统逆变器侧孤岛检测方法进行综述研究,对孤岛检测方法进行分类,并分析各种孤岛检测方法的原理和优缺点,阐述孤岛检测的非检测区(NDZ)4种常用的描述方法,说明了不同NDZ描述方法的适用场合和特点;指出通过频域分析技术优化增益控制可以减小但不能完全消除NDZ的误差,而采用不同检测原理的组合检测方法有可能实现无NDZ的孤岛检测.An overview of anti-islanding detection of power converter based distributed generation systems is presented in this paper. The anti-islanding methods are classified, their principles and advantages/disadvantages are analyzed. The 4 commonly used methods for mapping non-detection zone （NDZ） of the islanding detection are explained. Each method＇s characteristic and application field are also discussed. It is found that optimizing gain control with frequency domain analysis can reduce, but not eliminate, NDZ error; whereas, non-islanding inverter can be obtain by the combination of two anti-islanding methods with different work principles.
