分布式并网发电系统孤岛检测方法综述

Review of islanding detection methods for distributed generation

分布式发电系统并网运行时处于孤岛状态会对设备造成损坏,影响电力系统安全正常运行,严重时甚至可能会威肋到线路检修人员的人身安全。因此,对分布式发电系统孤岛检测方法的研究具有现实意义。本文综述了分布式并网发电系统孤岛检测的基本方法,并对其进行分类,最后对该领域的研究方向作出了展望。

Distributed generation system operate with grid in islanding condition will damage equipment,affect the safe and stable operation of power system,even threaten the safety of line maintenance people.Therefore,studying on distributed generation system in islanding condition has practical significance.This paper presents an overview of islanding detection methods for distributed generation systems.The paper classifies islanding detection methods.Finally,its study direction in the future is also looked ahead.
