摘　　要：分析了现有相模变换矩阵的不足,指出其单一模量不能适用于所有类型的故障,并结合三相输电线路完全换位情况下相模变换矩阵的数学性质,构造出了一种新型的相模变换矩阵。MATLAB仿真结果表明,新相模变换矩阵对各种类型的故障有效,能够实现单一模量反映所有故障类型的目的,且测距结果不受过渡电阻、故障类型影响。Considering the weakness that all currently frequently-used phase-mode transformation matrices can not be applicable to all types of fauhs, and combining with the mathematical properties of phase-mode transformation matrix in absolute transposition line, a new phase-mode transformation matrix is proposed in this paper. The simulations carried out by MATLAB show that the new phase-mode transformation matrix can reflect all tvoes of faults, and the results offault location are not affected by transition resistances and types of faults.
