摘　　要：电气主接线是电力系统网络结构的关键组成部分,定量分析其可靠性是电力系统可靠性研究的一个重要领域。将元件的故障以主动故障和被动故障分开考虑,利用了四状态元件模型,考虑了供需两方面的利益,使用最小割集法量化了电气主接线的可靠性与经济性指标,可以直观地分析比较其各自的可靠性与经济性水平,以此来综合选择最优的主接线方案,并以实际变电站的电气主接线为例,进行可靠性与经济性评估,验证了其方法的有效性。Bus configurations is a key part of network structure in power system, quantitative analysis of reliability of bus configurations is an important field of reliability research in power system. Considering active failure and passive failure of components, it is used four-state models of components and assessed reliability and economic indices of bus configurations using minimal cut-set method in the paper. It is an effective tool in selecting optimal program of bus configuration, by comparing and analyzing intuitively their levels of reliability combining economic indices. Effectivity of method is tested by evaluating reliability and economy of bus configurations of actual substation.
