河北省南部电网“十三五”220kV电网分区供电方法研究

Research on Sub-area Power Supply Scheme Based on 220 kV Power Grid During "13^(th) Five-year" Period

针对河北省南部电网短路电流日趋明显的问题,以石家庄电网为例分析220 k V电网分区供电方案,计算短路分支电流,提出有针对性的分区措施,并从电网拓扑结构上进一步优化分区方案,通过电气计算,说明该方案实施后可有效改善短路电流超标问题。

In view of the problem of short-circuit current in Hebei South Power Grid（ HSPG） becoming so increasingly obvious,the paper focus on the research of subarea power supply of 220 kV Shijiazhuang power grid. By calculating the branch current of short-circuit current,the corresponding measures of subarea power supply is put forward. Further,the paper makes optimization of the subarea scheme by the way of topological structure of Power Grid in order to ease the issue of short-circuit current effectively and give reference to the research on subarea supply of HSPG during the Five-Year Period.
