摘要
配电网中短路电流大小流向及分布发生的变化,使得含分布式电源的配电网中的各种保护发生了剧烈的改变,可能造成漏电保护及自动装置误动或拒动。本文通过仿真分析分布式电源对配电网电流保护的影响,验证了分布式电源的接入将影响继电保护的准确动作。
All protection contained in distributed generation（DG） is radical changed by the alteration of short-circuit cur-rent flows, size and distribution. Then it would occur that the leakage protection and automatic device might malfunctionor refuse to move because of the changes. Through the simulation, the impact on the current protection of the distributionnetwork by DG is analyzed, and the paper has verified that the accurate action of relay protection is affected by DG access.
