摘要

微电网在并网和孤岛2种状态间能够稳定切换运行，首先要解决的关键问题就是要有效检测出所处的运行状态，因此，孤岛检测技术一直是微电网研究的重点及热点问题。在详细分析传统经典孤岛检测算法的基础上，对近年来众多研究者提出的基于频率、相位、谐波和阻抗等不同基本电气量的改进检测算法进行总结，并指出具体的改进措施，对比分析其各自在检测盲区、精确性和工程实用性等特性上的优缺点。综述了多种检测相结合使用，以及基于其他原理的孤岛检测算法，并对未来孤岛检测算法的研究做出进一步的展望，以促进微电网技术向更加智能化的方向发展。

Abstract

In order to stabilize the microgrid operating between the networks and islands

the key issue that detecting the operating state effectively must be solved. Therefore

the island detection technology becomes important research field. Based on the detailed analysis of the classic detection algorithm

this paper summarized the improved detection algorithm based on electrical quantities

including frequency

phase

harmonics and impedance. The advantages and disadvantages of the different detection method in non-detection zone

accuracy and practicability

etc was pointed out. A variety of detection used in combination

and islanding detection algorithm based on other principles was reviewed

and a further prospects were done for the islanding detection algorithm research

in order to promote micro-grid technology more intelligent.
