摘　　要：配电系统是电力系统与用户联系并向用户供应电能和分配电能的重要环节,其可靠性指标是电力系统结构及运行特性的集中反映。针对配电系统结构复杂、负荷点密集、计算量大的特点,将等值法与最小路径法相结合,对配电系统进行可靠性评估,计算配电系统各支路的可靠性指标,找出配电系统中的薄弱环节,提出有关提高配电系统可靠性的措施。Power distribution system has an important role in the communication between power network and consumers,whose reliability index inflects the struction and characteristic of power network.In the light of the characteristics of distribution network, including complex structure,intensive load point and large computation,the minimal path and equivalent method are combined to evaluate the reliability of distribution system,and appropriate methods to improve reliability are proposed.

关 键 词：配电系统 可靠性指标 等值法 最小路径法
