500kV固贤输变电工程内过电压计算研究

Study on Overvoltage Calculation of Guxian 500 kV Transmission and Transformation Project

由于固贤500kV变电站处于500kV山西中部电网末端,运行条件较为苛刻,需要进行过电压研究。计算分析了启动调试方式和运行方式下的操作过电压、潜供电流、重合闸时间等,并针对运行要求提出推荐意见,以期为同类工程提供建设、启动调试及运行的参考意见。

Guxian 500 kV substation which is located in terminal part of middle Shanxi power grid requires overvoltage research.Consequently, the related system parameters of Guxian substation under startup commissioning mode and normal operation mode are calculated. According to the characteristics of the project, the recommendation opinions on startup commissioning and normal operation are given, in hope of providing reference for the same kind of project.
