摘要
为了解油田35kV配电网受雷电过电压的影响程度,利用ATP电磁暂态仿真计算程序,对南阳油田江河变电站在不同情况下的雷电侵入波进行了仿真计算。由仿真分析的结果可知系统受雷击时主设备上过电压受多方面因素影响,类如系统的运行方式、杆塔的接地电阻等。研究的结果为减小雷电过电压的危害,提高配电系统的可靠性提供参考。
In order to investigate the effect of lightning overvoltage on 35kV distribution line of oilfield,alternative transient program(ATP) is used to simulate the lightning invasion wave into Jianghe substation in different situations.The result shows that lightning overvoltage on the main devices is influenced by various factors when the system is struck by lightning,such as operation mode and grounding resistance.Accordingly the precautionary and protective measures are presented to ensure the safe operation of power system.
