摘　　要：通过对三种主要的本地被动式孤岛检测技术的分析,推导出测量过(欠)压/过(欠)频孤岛检测技术优劣的方法——孤岛检测技术非检测区。由非检测区分析得出,通过减小负荷品质因数和主动式孤岛检测技术相配合的方法减小或消除非检测区。仿真试验验证了理论推导的正确性。This paper analyzed three local passive islanding detections, and derived a method—— the nonedetection zone of the technology of passive islanding detection, which can detect the advantages or disadvantages of the technology of passive islanding detection for the measurement of over （under） voltage and over （under） frequency. Through the analysis of non-detection zone, a conclusion aiming to reduce or eliminate the non-detection zone can be obtained by reducing the load quality factor associated with the cooperation of the technology of active islanding detection, and the correctness of the derived theory can be verified by the simulation.
