浅议短路电流对分布式电源接入的影响及改进措施

Brief Discussion on the Influence of Short Crcuit Current on the Access of Distributed Power Supply and Improvement Measures

在配电网运行过程中,分布式电源对支路电流、潮流分布、网络损耗及节点电源等特性均带来积极影响,为提高配电网运行及管理质量奠定基础,使电网运行更为稳定。为适应新时代配电网络发展需求,需拓展接入分布式电源的途径,采取相关技术措施来提高配电网接纳分布式电源的能力。本文针对短路电流对分布式电源接入的影响提出改进措施,其中包括一次设备的改造和运行管理方法的调整,最大限度保障分布式电源的接入。

In the process of distribution network operation,distributed generation has a positive impact on the characteristics of branch current,power flow distribution,network loss and voltage nodes,which makes the operation of power grid more stable and lays a foundation for improving the operation and management quality of power grid.In order to effectively meet the needs of the development of distribution network in the new era,it is necessary to expand the access ways of distributed generation and take relevant technical measures to improve the ability of distribution network to accept distributed generation.In view of the impact of short circuit current on the access of distributed generation,improvement measures are put forward,including the modification of primary equipment and the adjustment of operation management methods,in order to maximize the access of distributed generation.
