摘要
讨论了求解多导体传输线 (MTL)的时域有限差分法(FDTD) ,并将其扩展到有分支结构的传输线中。通过实例与Bergeron法进行对比计算 ,表明FDTD法可以计算传输线的波过程。建立了变电站空载母线波过程分析的MTL计算模型 ,并用FDTD法对变电站空载母线加电的波过程进行了数值分析 ,计算结果可用于变电站开关场内二次设备电磁干扰 (EMI)问题的研究。
For studying the problem of electromagnetic interference(EMI) at electric power stations and substations, a technique to solve multi conductor transmission line(MTL) problems with the finite difference time domain(FDTD) method is discussed and extended to the structure with branches. Contrasted with Bergeron's methods in an example, FDTD method can be well used to calculate the wave processes on MTL. A simple model of substation buses without load is set up, and its wave propagation is analyzed. These results will be very useful in the next study.
