Abstract:

电缆的电感值在电力系统各种计算分析中起着重要的作用,针对直线电缆的电感计算问题研究已经较多且根据经验公式容易计算得出,但是关于弯曲电缆的电感问题研究得较少.弯曲电缆电感参数不易得到,常规经验公式只能计算某些特殊形状电缆的电感.基于有限元分析的方法,以单芯XLPE电缆为例,在Ansys中建立电缆的模型进行仿真,研究弯曲电缆电感计算的问题.分别计算直线电缆与弯曲电缆的电感值并用公式验证了仿真结果的正确性,将二者的值进行对比,得出同样长度的弯曲电缆电感值比直线电缆电感值小的结论.该结果说明在电力系统分析计算时需要考虑到弯曲电缆的影响,这样可以为电缆的其他各方面研究提供更加准确的电缆参数
