河北省南部电网短路电流分析及限制措施

在对河北省南部电网短路电流计算的基础上,分析河北省南部电网短路电流快速增加的原因,分别从电源接入、网络结构、设备选型、运行方式等方面介绍限制短路电流的措施,以廉州220 kV变电站作为典型案例,给出限制220kV短路电流的建议。

Analysis of Short-circuit Current of Hebei Southern Power Grid and Control Measures

On the basis of calculating the short-circuit current of Hebei southern network in 2010,this paper analyzes the causes that lead to short-circuit current increased quickly,and introduces the restricted measures from the aspects of generator connect-in strategy,network structure,equipment selection,operation mode,and then takes Lianzhou 220 kV substation as an example,presents the suggestion scheme to restrict 220 kV short-circuit current increasing.
