On Research with the Transmission Line Modeling(TLM) to Caculate and Analyze Power Transmission Line

从传输线理论出发 ,介绍了一种同时对时间和空间进行离散化的数值计算方法—传输线模型法 ,简称 TL M法。利用该法推导出三相电力输电线的 TL M模型 ,并应用该模型通过实例进行计算 ,计算结果与其它方法相比较很接近 ,证明该方法是正确的。可用于远距离、超高压电力输电线的各种计算中 ,并可推广应用于电磁场、声波。

This paper introduces a new method(TLM) to solve a power transmission line problem. The TLM model of 3-phase power transmission line is developed. Through the computing results of an example, the method is proven feasible, good agreement between the transmission line modeling(TLM) and other methods is achieved. The TLM model can be used for long diatance and high votage power transmission line, and so as to get better answer and analyze system characteristics.
