华东500 kV电网短路电流分析及其限制措施探讨

Short-circuit current of 500 kV East China power grid and its limitation

在2006～2007年华东电网的短路电流分析和潮流分析的基础上，对解决2006至2007年华东500kV电网短路电流超标问题的各种方案进行了分析比较，并给出了相应的解决措施。详细介绍了江苏和浙江电网短路电流限制措施。

Based on the analysis of short-circuit current and power flow of East China Power Grid from 2006 to 2007, the various schemes for limitation of the large short-circuit current of the 500 kV grids in East China during 2006 - 2007 are analyzed and compared, and relevffnt countermeasures are put forward. The measures adopted to limit the short-circuit current for Jiangsu and Zheiiang power grids are recommended in detail.
