| 摘 要： | 青海格尔木地区平均海拔3 000 m以上,其110 kV察汗诺-格尔木输电线路常年遭遇风偏闪络事故。为了研究其风偏闪络频繁发生的原因,建立了该线路段的导线-绝缘子耦合模型,用Matlab模拟了当地平均风速为30 m/s的脉动风场,用ANSYS仿真了该模型在脉动风作用下的绝缘子串风偏响应。仿真结果表明,悬垂绝缘子在雷电过电压下发生风偏闪络的概率较大,在线路风偏改造时应重点校核。

| Abstract: | The average elevation of Geermu City, Qinghai Province is more than 3 000 meters. 110 kV Chahanluo-Geermu line have windage yaw flashover accidents throughout the years. In order to study reasons of frequent accidents in windage yaw flashover of overhead transmission line, the coupling model of conductor-insulator is established. The stochastic turbulent wind field with average 30 m/s wind speed is simulated by MATLAB. Insulator transient response analysis under stochastic wind velocity field is also performed by ANSYS. Simulation results show that suspension insulators have large probability of wind age yaw flashover under the lightning overvoltage and higher priority during line rebuilding process. |
