摘要 为提高超高压输电线路单相自动重合闸的成功率,需限制各种运行方式下线路的潜供电流和恢复电压。本文利用ATP-EMTP建立了苗尾500kV输电线路的分布参数模型,通过仿真得出苗尾出线并联中性点小电抗器的取值与出线潜供电流、恢复电压之间的关系,为线路重合闸设置和继电保护整定提供依据。

Abstract:In order to improve the success rate of single-phase automatic reclosure of EHV transmission lines, the submersible current and recovery voltage under various operation modes need to be restricted. In this paper, the distribution parameter model of the 500kV transmission line of the seedling tail is established by ATP-EMTP. Through the simulation, the relationship between the value of the high resistance neutral point small reactor and the potential supply current and the recovery voltage is obtained. It provides the basis for the setting of the line reclosing and the relay protection setting.
