摘要
通过对时变电导（或电阻）作适当处理，可较方便地使领域内的输电线路电磁暂态计算既能考虑线路参数的频变又可考虑过渡电阻的时变，从而做到对发展性短路故障的精确数字仿真。本文方法在abc相分量上进行计算，所以适用于均匀换位或不换位的单回线、双回线和线路传播常数矩阵ZY不能对角化的情况。故障时刻故障点电压的相角亦可任意设定。
Through proper processing the time - varying conductance (or nsistance), both the frequent- dependence of line paramenter and fault transien resistance can be considetal in the computation of line faultelectromagnetic transients in s - domain, thus accurate digital simulation on developing faults can be carriedout. The proposed method is performed in abc phase - coordination, so it can be applied to transposition oruntransposition lines (single - or double - circuit lines) and the non - diagonalizable situaion of producematrix ZY. Voltage phase - angle at a fault point can be designated with ease.
