电力系统复杂故障分析一般计算方法的改进

复杂故障计算是大型电力网络仿真计算中不可缺少的一部分。当故障发生在线路上时，电力系统复杂故障分析的一般计算方法没有很好的实时性。针对这个问题，提出在故障点处对原网络进行电路等值，求解出故障电流，再把故障电流分解到节点上进行分析计算。这个方法较好地保持了原有算法的优点，便于实现计算机编程，从而提高了故障计算的速度。

Improvement on canonical algorithm in complex fault analysis of power system

Complex fault computation is one of the most important parts in large power system simulation. As for a line fault, the real-time capability of the canonical algorithm in complex fault analysis of power system is not very good. Accordingly, it is suggested that circuit equivalence of the original system be made at the fault point to work out fault current, and then the fault current be decomposed to nodes for analysis and calculation. Properly maintaining the advantages of the original algorithm, the proposed method facilitates computer programming and thus speeds up fault calculation.
