摘要
分析了已有配电网可靠性评估方法在计算机实现时存在的问题,结合现场对可靠性评估的实际要求,提出了一种配电网改进可靠性评估方法。该算法无需网络等值过程,原理简单清晰,易于在计算机上实现;在需要计算某负荷点可靠性时,无需分析所有元件故障,且能给出对该负荷点可靠性影响的各元件排序,以便供电部门了解网络的关键元件;该方法可方便地与配网重构算法相结合,实现故障后的负荷转移计算;在搜索过程中无需形成网络的邻接矩阵或特殊的链表关系,直接采用最基本的节点数据表和支路数据表对网络进行搜索,与现场数据接口方便,搜索算法采用递归算法,可大大减少编程工作量,提高程序执行效率。算例分析和现场应用表明了本方法的有效性和实用性。
By illuminating the problems of previous evaluation algorithms, and according to the actual demands of engineering applica- tion, an improved reliability evaluation algorithm for distribution network is put forward in this paper. This algorithm needs no network equivalence process, and its principle is clear and succinct so as to easy programming. When only one load point is concerned, it does not need to analyze fault results of all equipments, and can conclude the influence degree of pertinent equipments to certain load point so as to help the supplier to know which equipments is critical. This algorithm can easily cooperate with fault reconfiguration. It needs only widely used data format for the convenient data interface with engineering application, no adjacency matrix and special chain table are needed. Recursive search is used in the algorithm, which reduces the amount of programming and improves its effi- ciency.
