摘要
对110 kV单进线山区敞开式变电所雷电波入侵过电压进行了分析。利用贝杰隆等值网络法和ATP-EMTP,M atlab程序,对雷电波入侵过电压进行仿真,并对110 kV敞开式变电所雷电波入侵过电压进行了仿真计算。分析了产生过电压的因素,并提出了提高110 kV单进线山区敞开式变电所防雷保护的措施。
The lightning intruded wave overvoltage in 110 kV single incoming line open-air substation in mountain area was analyzed in this paper. By using Bergeron equivalent network method, ATP-EMTP （electromagnetic transient program） and Matlab program, lightning intruded wave overvoltage was simulated and calculated. The cause of lightning intruded wave overvoltage was analyzed and the strategies to improve lightning protection were put forward.
