摘　　要：研究基于ATP-EMTP仿真的变电站雷电侵入波过电压保护误动作识别方法,提升变电站识别过电压误动作的精度.采用ATP-EMTP构建变电站输电系统仿真模型,通过S变换判别变电站输电系统所遭受的攻击类型,在判别得出雷电侵入波攻击后,设计保护运行监测评估架构,监测评估过电压保护动作,识别变电站输电系统雷电侵入波过电压保护误动作.实验结果表明,该方法可准确判别变电站输电系统线路所遭受的攻击类别,识别结果准确,识别性能稳定可靠,实际应用性较强,为保障变电站及整个电力系统的安全运行提供有效帮助.Based on ATP-EMTP simulation, identification method of substation lightning intrusion wave overvoltage protection maloperation is studied to improve the accuracy of substation identification. ATP-EMTP is used to build the simulation model of substation transmission system, and the attack types of substation transmission system are identified by S-transform. After the lightning invasion wave attack is recognized, the protection operation monitoring and evaluation framework is designed to monitor and evaluate the overvoltage protection action, and discern the overvoltage protection maloperation of lightning intrusion wave The experimental results show that the method can accurately identify the types of attacks suffered by the transmission system lines of substation, the identification results are accurate, the identification performance is stable and reliable, and the practical application is strong, which provides effective help for the safe operation of substation and the whole power system.
