AN ACCURATE METHOD OF FAULT ANALYSIS FOR RESPONSE OF FAULTY DISTANT TRANSMISSION LINE

本文应用分布参数故障传输线复频域布参数节点导纳方程和另一种数值拉普拉斯反变换方法 ,对故障传输线首末端电压响应进行了分析。基于 matlab的分析结果显示 ,与应用 pade有理函数近似的拉普拉斯反变换方法相比较 ,该方法更易于分析 。

Based on the nodal admittance matrix of faulty transmission line in complex frequency domain,this paper applies another numerical inverse Laplace transform(NILT)to analyze the voltage response at the ends of transmission line.Some simulations are completed by using matlab.The results show that this method is more efficient and accurate than the method of NILT in which e st is approximated by the Pade rational function.
