摘要
晋北—南京直流特高压工程投产后,山西电网结构发生了重大变化,从电网静态安全、短路比、暂态安全稳定及暂态过电压等方面分析了交直流系统相互作用下山西电网的稳定特性,为山西电网的稳定运行提供了理论依据。配套电源投产后,晋北直流特高压送电8 000 MW,晋北换流站运行设备无过载现象,满足运行控制要求。
After Jinbei-Nanjing DC UHV project is put into operation, Shanxi power grid structure has changed significantly. This paper analyzes the stability of Shanxi power grid under the interaction of AC and DC systems from the grid static security, short circuit ratio, transient safety and transient overvoltage, which provides a theoretical basis for the stable operation of Shanxi Power Grid. After the matching power source is put into operation, the transmission of power load from Jinbei DC UHV has reached 8 000 MW and no overload phenomenon occurred at converter station.
