摘　　要：基于电流补偿法和网络分块算法 ,提出了计算变结构电力系统互感 /无互感线路上故障的统一断口模型以及计算断口等值参数的新方法 ,避免了现有方法的复杂繁琐 ,简化了互感线路的断相故障计算 。Based on the current compensation principle and network piecewise method, a generalized open conductor model to solve the unsymmetrical open conductor fault on the transmission lines with or without mutual coupling is presented.Further a novel algorithm to calculate fault port equivalent parameters is proposed. And the computations involved is simplified and thus the complexity and heavy calculations of methods available are completedly avoided. Meanwhile, the fault current of the fault line and its mutual coupled lines can be obtained directly and easily.
