摘要
针对我国某地区由于110/66 k V高压配电网形成网状布局导致短路电流超标的问题,应用电网分层分区的方法提出两种分区运行方式,并对两种分区方式进行N-1静态安全分析和短路电流限制效果比较。结果表明:将66 k V线路分成4片网运行后可有效解决该地区短路电流超标问题,该分层分区控制方法可用于短路电流水平过高的配电网运行规划中。
Aiming at the problems of 110/66 kV HV distribution network formed network structure leading the short circuit current exceed standard in some region of China,applying the methods of hierarchy and partition,puts forward two kinds of partitioned operation modes,and compares the effects of two modes with N-1 static security analysis and short circuit current limitation. The result shows that 66 kV line divide into four parts can effectively solve the problem of the short circuit current exceed standard in the region. This hierarchy and partition control method may use in planning and operation of distribution network of short circuit current exceed standard.
