摘　　要：随着电力系统的发展,广泛采用自动重合闸方法来提高电力系统的稳定性,对故障选相的要求也越来越高。微机保护装置不仅要求能够准确判别出单相故障的故障相,还要准确判断出相间故障的相别。因此提出了一种基于模故障分量灰关联分析法的电力系统故障选相新方法,并通过Matlab进行建模仿真,证实了这一方法的具有需要样本少,计算量较小,选相准确度和可靠性高的特点,具有较高的实用价值。With the development of electric power system, widely used in automatic reclosing method to improve the stability of power system, the requirement of fault phase selection is becoming more and more high. Microcomputer protection device requires not only can accurately distinguish the fault phase of single-phase fault , and to accurately judge the fault phase of Phase to phase fault. Thus raise a method of electric power system fault phase selection based on Grey Relational Analysis, and carries on the modeling and simulation by Matlab, confirmed this method needs less samples, small amount of calculation, the accuracy of phase selection and the characteristics of high reliability, has high practical value.
