| 摘 要： | 介绍了一种基于模态的六相电力系统的故障计算方法,利用六相系统的对称性,通过对阻抗阵进行变形,使其解耦成两组三相系统,并分别对这两组三相系统采用不对称故障的分析方法,将其组成六相系统的复合序网,以此对其进行不对称短路故障的计算。

| Abstract: | This paper introduces a model based fault analysis method for six-phase transmission system. Using basic symmetry properties of six-phase transmission line, this paper firstly transforms the impedence matrix to two uncoupled three-phase systems, and then calculates the two systems with asymmetrical fault analysis method respectively, finally does asymmetrical short-circuit calculation after composing the two systems into six-phase compound sequence system. |

| Keywords: | six-phase transmission short-circuit calculation asymmetry fault |
