| 摘 要： | 研究输电导线的舞动及仿真时,需要计及多种激励因素。在不同传输功率时,导线电流产生的安培力在导线舞动仿真中是否计及、如何计及等问题需要回答。从基本电磁场理论出发,推导了通用输电线安培力计算表达式、画出了安培力随时间变化的轨迹图。由于导线质量较大、安培力较小且其方向与大小随电网频率相同、导线舞动频率与电网电流频率相比很低,对导线舞动的激励可以忽略,在仿真计算中不计及其作用。

| Abstract: | When studying the dancing of transmission line,many factors should be considered. It must be paid attentions to the effect of wires Ampere force in line dancing if the transmission power is different. Based on the theory of electromagnetic field,this paper got the expression and drew the vector of Ampere force. Because line quality is big and the force is small,the electromagnetic field impact can be ignored in simulation. |
