分布式发电对继电保护的影响

随着新能源的应用与发展,以新能源发电为基础的分布式发电技术有着高效、节能,缓解不可再生能源紧缺的优点,但也出现了一些新的问题,如电能质量、电网控制等,分布式发电对配网原有的继电保护产生的影响尤其巨大。首先介绍分布式发电对继电保护的几点影响,然后总结了一些解决方法,最后讨论了一些可行的方法,并分析了用自适应继电保护对含有分布式电源的配电网进行整定计算的方法。

Influence of Distributed Power Generation on Relay Protection

With the development of renewable energy,the high efficiency and energy conservation of the distributed power generation can remit the requirement intensity of non-renewable energy,but it results in many new problems,such as power quality,power-network control and especially the relay protection.The influence of the distributed power generation on relay protection is introduced,and then the solutions are introduced.At last,some viable solutions are offered to the problems.The setting calculation with the adaptive relay protection for the distribution network that contains one or more distributed generations is analyzed.
