摘要
分布式发电以其投资省、损耗低、运行简单灵活、与环境兼容等特点,近年来受到越来越多的关注和研究.随着分布式发电接入系统配电网的容量越来越大,其对系统的影响也越来越显著.在介绍分布式发电的基础上,综述了分布式发电对电力系统的影响,主要分析了在稳态电压、电压波动等电能质量和三段式电流保护、自动重合闸、距离保护等继电保护方面的影响.
Distributed generation has attracted more and more attention and research in recent years because of its low investment,low loss,simple and flexible operation,and environmental compatibility.With the increasing capacity of distributed generation parallel operation on power system,its impact on power system is more and more significant.Based on the introduction of distributed generation,this paper summarizes the impact of distributed generation on power system,mainly analyzes the impact on power quality such as steady-state voltage and voltage fluctuation,and relay protection such as three-stage current protection,automatic reclosing and distance protection.
