摘　　要：本文介绍用复矩阵特征模量分解方法精确计算高压同杆双回线故障。在计及线路换位和分布参数条件下精确计算单线和跨线故障。文中还介绍了横向复杂故障的计算方法。This paper introduces accurate fault calculation for parallel power lines on the same tower by eigenanalysis of complex matrix. This calculation method considers the effect of power line transposing and distributed capacitance. The method has high accuracy and can be used for calculating fault components of parallel power lines on the same tower when fault is on one line or between two lines or complex faults crossing lines. This method can be used for investigation the performance of relays and other devices in the parallel power lines and analysis of the accidents of parallel power lines.
