摘要
从4个方面分析了上海220kV电网短路电流上升的原因,对国际和国内各种控制短路电流的措施进行研究,针对特大型城市的220kV密集型电网提出了一种新的运行模式,并对“十一五”期间短路电流问题比较突出的杨行分区、南桥分区等2个220kV分区提出了切实可行的控制措施。
The reasons of the short-circuit current increase in Shanghai 220 kV grids are analyzed in 4 aspects, and the measurements adopted at home and abroad for controlling short-circuit current are studied. A new operation mode for the dense 220 kV grids of extra large cities is put forward, and concrete and applicable controlling measurements for the two 220 kV districts of Yanghang and Nanqiao with serious short-circuit current problems during the Eleventh Five-Year plan are put forward.
