摘　　要：通过研究相位跳变法与电压正反馈法,并以这两种基本检测方法为基础,提出组合式的孤岛检测方法。该方法可以有效发挥相位跳变检测法检测时间短和电压正反馈检测法检测无死区的优点,针对不同负荷类型和功率匹配程度,构建相关的模拟实验,进一步验证新方法的正确性。Based on the study of phase jump method and voltage positive feedback method,a combined islanding detection method is proposed.This method can give full play to the advantages of short detection time of phase jump detection method and no dead zone detection of positive voltage feedback detection method.According to different load types and power matching degree,relevant simulation experiments are constructed to further verify the correctness of the new method.
