摘　　要：在故障模式后果分析法的基础上 ,提出配电网络可靠性指标计算的向量法。该方法以构造负荷点供电“最小路馈线段行向量”的方法 ,方便地求得带子馈线、备用电源的复杂配电网络的可靠性指标。在最小路馈线段行向量生成后 ,计算中不需要再考虑网络结构 ,可简化计算。同时 ,还有助于方便地找出配电网中的薄弱环节。实例计算表明 ,向量法计算结果准确。This paper proposes a vector algorithm based on the famous failure mode and effect analysis as an approach to reliability evaluation of a complex distribution system. With the new method, a minimal path feeder vector can be constructed to produce reliability indexes of a complex distribution system with sub feeders and alternative suppliers. After creating the feeder vector, it will not be necessary to consider the configuration of the distribution system. Furthermore, the process of calculation is much simpler than other methods. An example shows that the algorithm proposed is practical.
