摘要
分析了500 kV架空输电线路感应电产生的原因,提出了采用计算机仿真来求感应电压和电流大小的方法。仿真结果表明,500 kV输电线路的感应电压计算,可以仅考虑静电感应产生的耦合,而忽略电磁感应。仿真计算结果符合实际情况,该方法计算简单实用,易于推广。
This paper analyses the reason that causes induced voltage in 500 kV transmission lines and proposes the method to calculate the induced voltage and current by computer simulation.The simulation result shows that it is feasible to consider only the electrostatic induction and neglect the electromagnetic induction in the induction voltage calculation of 500 kV transmission lines.The result of calculation accords with the actual conditions.This method has high practicability and is worth popularizing.
