摘　　要：利用PSCAD电磁暂态仿真软件,对典型500 k V变电站和输电线路建模,计算出了潜供电流和恢复电压。该模型对500 k V系统有效熄弧提供了重要参数,为重合闸设备的重合时间设置和相关的继电保护定值整定,提供了切实可行的依据。对500 k V输变电工程的调试、启动和运行具有一定的指导意义。The electromagnetic transient simulation software PSCAD is used;the models of typical 500 kV substations and transmission lines are built up and the secondary arc current and the recovery voltage are calculated.This model provides an important parameter to effectively extinguishing arc in 500 k V system and also provides a practical basis to set the reclosing time of switching equipment and to set the relative relay protection fixed values.The results of this paper has a certain reference to the debugging and commissioning of500 k V power transmission and transformation project.
