摘　　要：根据江苏电网2009年规划,经计算发现部分500 kV变电站存在220 kV侧单相短路电流将超标现象,针对该问题,提出了几种限制单相短路电流的措施,并进行了相应的计算分析。According to the Jiangsu grid planning in 2009, through calculation the single phase short circuit current will exceed the limit at the 220 kV bus in partial 500 kV substations. Aiming at this issue, several limit the single phase short circuit current are proposed, and the related calculation and analysis are carried out.
