摘　　要：基于广度优先搜索算法构造了复杂配电网络的等效模型,采用区域节点行向量法对复杂配电网络进行了可靠性评估。给出了区域节点的定义,采用广度优先搜索算法将复杂配电网络等效为由区域节点和开关元件组成的模型,采用区域节点行向量法得到了负荷节点和系统的可靠性评估指标。在该模型和算法中,区域节点的形成算法以支路为研究对象,操作简单,网络适应性强。采用区域节点行向量法对复杂配电网络进行可靠性评估时,便于考虑开关装置故障的影响,实用性较强。RBTS-bus6系统的评估结果及其与现有分区方法的比较结果表明了该模型和算法在简化网络和提高运算速度方面具有明显优势,在适应网络结构变化方面具有较好的鲁棒性。Based on breadth first search algorithm an equivalent model for complicated distribution system is constructed, and the reliability of distribution system is evaluated by zone node row vector algorithm. Firstly, the definition of zone node is given and by means of breadth first search algorithm a model consisting of zone nodes and switch elements is equivalent to distribution network, then according to zone node row vector the reliability indices of load points and system are evaluated. In the proposed algorithm and model the definition of zone node makes the zone sectioning more efficient; in the formation of this algorithm the branches are the objects, so the operation is simple and this method possesses powerful adaptability to networks. By means of using new zone node row vector algorithm in reliability evaluation, it is convenient for considering the influence of switch faults, and it improves the practicability of the proposed method. Comparing the evaluation results of RBTS bus-6 system by the proposed method with that by existing sectioning method, it is shown that the proposed method possesses evident superiority in simplifying network and improving calculation speed. In addition, the proposed method possesses better robustness in the adaptation of structural changes of distribution networks.
