宁夏电网短路电流水平分析及限制措施

Analysis and restriction measure on the short-circuit level for Ningxia power grid

针对未来2～3年宁夏电网短路水平，通过计算，分析了超标点短路电流增高的主要原因。从网架结构、设备更换及运行方式调整等方面提出了限制措施。应用结果表明：限制措施确保了电网安全稳定运行。

Aiming at the short-circuit level of future 2-3 years in Ningxia power grid, by calculating analyzes the main cause of short-circuit current to increase high for excessive standard points, puts forward restriction measures from the aspects of network structure, equipment change operation mode adjustment. The application result shows that the restriction measures ensure power grid safe and steady operation.
