分布式发电系统继电保护技术

分布式发电以其能源多样化、环保、节能、高效等多方面的优越性而得到了越来越广泛的应用。分析了分布式发电设备接入配电网后对继电保护的影响及解决措施．重点讨论了国内外有关含有分布式发电的配电网继电保护技术及分布式发电的孤岛检测算法，并研究了这些保护策略的特点，为完善和改进分布式发电的继电保护技术提供一定的参考。

Research of Relay Protection for Distributed Generation System

Distributed generation （DG） has been used more and more broadly for its merits including diversification of energy sources, environment-friend property, energy saving and high performance and so on. In this paper its influence on relay protection is analyzed and the solution is provided. Relay protective technique for grid with DG and islanding detection algorithm at home and abroad are discussed emphatically and the characteristics of them are presented. It provides references for the improvement of relay protection of DG.
