中文摘要：
以开关为对象,提出了复杂中压配电网可靠性顺流评估算法。该算法根据原始数据形成开关对作用元件、节点和开关对之间的父子关系矩阵,以开关对的作用元件组为单位进行可靠性分析,避免了复杂的故障搜索,根据开关对之间的父子关系矩阵可快速确定节点的故障类型,形成系统和节点的可靠性指标。RBTS-bus6系统和实际中压配电系统的仿真计算结果表明了该算法的正确性、高效性和实用性。
英文摘要：
Taking switches as the subject investigated, a down-stream algorithm of reliability evaluation for complex medium-voltage distribution networks is proposed. In this algorithm, according to the raw data the father-child relations between switch-pair and acting components, which is expressed as incidence matrix （IM）, as well as that between node and switch-pair are formed; taking the acting component group as the object, the reliability is analyzed, thus the complex fault search can be avoided; according to the IM between switch-pairs the fault type of the node can be quickly determined, thus the reliability indices for system, feeders and nodes are formed. The simulation results of RBTS-bus6 system and actual medium-voltage distribution system show that the proposed algorithm is correct, efficient and practicable.
