基于有限元法的谐波作用对电缆及其接头的影响研究OACSTPCD
Research on the influence of harmonic action on cable and its joint based on FEM
现有关于电缆及其接头温度的研究大多按照基波情况考虑,大量非线性负载的使用使输电线路中的谐波含量显著增加,谐波对电缆及其接头附加损耗与温升的影响不容忽视.文中以64/110 kV单芯电缆及预制式电缆接头为例,建立了电缆及其接头的有限元仿真模型,基于电磁-热耦合法,分析了谐波含量与谐波次数对电缆及其接头的影响,并引入等效电流因数,实现多次谐波共存环境下对电缆发热损耗及温度的快速计算.仿真结果表明:谐波含量与谐波次数均会影响电缆的损耗及温度,谐波可能导…查看全部>>
Most of the existing researches on cable and its joint temperature are based on the fundamental wave.With the wide application of nonlinear load in power grid,the harmonic content of transmission lines increases significantly.The in-fluence of harmonics on the additional loss and temperature rise of cable and its joint cannot be ignored.In this paper,taking 64/110 kV single-core cable and its joint as examples,the finite element analysis models(FEM)are estab…查看全部>>
