摘要
用故障分解方法研究电力系统复杂故障的计算．是把复杂故障分解成单相接地短路、单相断线及两相短路三种形式的组合，根据迭加原理及边界条件建立复杂故障计算模型．该方法模型简单，编程方便，能适用于任何组合型式的多重故障计算，对串并混合型的多重故障，采用该方法尤其具有优越性．
The complex fault calculation of electric power system is studies by means of the fault dissociation in this paper. Based on the principle of superposition and boundary condition, a calculation model is given through dividing complex fault into three kinds of simple mode-phase-to-ground fault of one phase, phase breaking fault of one phase and phase-to-phase short fault between two phase. This method is simple in calculation model and convenient in program composition. It can be applied to calculate any complex fault especially series--mode and parallel-mode mixed fault.
