分布式电源对配电网继电保护的影响

摘要

Introduction was made to the current development of distributed generation, the structure and protection configuration of existing distribution network. Analysis was made to the influence of the join of distributed generation on the existing protection of distribution network. Simulink software was adopted to design the simulation plan and the plan was verified. On the basis of simulation results, this paper obtained the change relationship between the distributed generation capacity and the current flowing through every protection of feeder, raising corresponding solutions in connection with different situations.%介绍了分布式电源的发展情况、现有配电网的结构及保护的配置方案,分析了分布式电源的加入对于现有配电网保护的影响,利用Simulink软件设计仿真方案并进行验证,根据仿真结果得出了分布式电源容量与馈线各处保护所流过电流的变化关系,针对不同情况提出相应解决方案。
