摘要
特高压变电站是1000k V交流输电系统枢纽站,对整个电网的安全运行非常重要,因此要求有可靠的防雷措施.沿输电线路侵入变电站的雷电过电压现行最为常见,所以对特高压变电站进行雷电侵入分析研究十分必要.本论文以某1000k V特高压变电站为例,将变电站和进线段结合起来,并考虑变电站运行方式、工频电压、冲击接地电阻等因素的影响,对雷电沿输电线路侵入变电站后产生的过电压进行计算分析,得到相应的雷电过电压保护措施.
1000k V UHV AC transmission system substation hub for the safe operation of the entire power grid is very important, thus requiring a reliable lightning protection measures. Lightning invasion along the transmission line over-voltage substation current most common, so the UHV substation lightning invasion analysis is necessary.In this paper, a 1000 k V UHV substation, for example, the substation and into the line together, and consider the substation operation mode, the impact frequency voltage, resistance, and other factors, the impact of the grounding,lightning along the transmission line transformer substation after the invasion generated overvoltage Calculation and analysis, the corresponding Lightning overvoltage protection.
