中文摘要: 高密度光伏系统接入配电网后,改变了配电网络的结构及配电网中短路电流的分布,对配电网继电保护产生了影响.以长兴县配电网线路为例,利用DIgGSILENT PowerFactory软件进行仿真,研究了光伏电源接入配电网对自动重合闸、保护范围和灵敏度3个方面的影响,并提出了相应的解决方案.
Abstract:Changs are caused to the structure of distribution network and the short circuit current distribution in distribution network by the high-density photovoltaic power system paralleled into distribution network.thus the relay protection of distribution network is influenced.With an example of photovoltaic power supply paralleled into distribution network and using DIgGSILENT PowerFactory simulation software, a conclusion is drawn that the photovoltaic power has an influence on automatic reclosing, protection area and sensitivity.
keywords: potovoltaic power supply distribution network relay protection automatic reclosing relay protection sensitivity
