摘要(Abstract)：

指出了中压配电网可靠性评估的特点,提出了复杂配电网的定义,介绍了配电网可靠性评估方法的研究现状。主要从网络连通性分析方面对解析法中的几种常用方法进行了分析比较,将其分为面向负荷点、面向元件和面向开关设备的方法以及混合算法。对于面向负荷点的方法,由于针对每个负荷点需要进行一次网络拓扑分析,系统规模大时耗时较长。对于面向元件的方法,其主要方法故障模式后果分析法原理简单,但只适用于简单辐射型网络。对于面向开关设备的方法,一般的故障扩散法可用于复杂配电网络,但由于针对每一个失效事件或分块都需要进行一次网络拓扑分析,算法复杂又耗时。基于等值的混合算法改善了计算速度,但仍有原有算法的特点。最后,展望了现阶段在可靠性评估方法上需进行研究和改进的方向。
