摘要
提出了一种将递归算法和等值法结合的复杂辐射状配电网的可靠性评估算法。该算法针对配电网结构的递归性特点,首先将配电网分层处理,采取左子女—右兄弟的二叉树表示方法将网络分层存储为树型数据结构形式,然后通过对树的递归遍历将配电网的子馈线进行合理的可靠性等效,简化为一个形式简单的网络。在遍历过程中递归调用可靠性计算公式,最终得到整个配电网的负荷点可靠性指标和系统可靠性指标。实例计算验证了该方法的有效性。
This paper proposes an algorithm to evaluate the reliability of complex radial distribution network by compounding recursive algorithm and method of equivalents. According to the recursiveness of distribution network, this new algorithm first disposes the distribution network and stores the data in the form of a left-child and right-sibling binary tree, then makes reasonable equivalents of reliability for the distribution network subfeeders based on the recursive traversal of the tree, and thus simplifies the distribution network in form. During the ergodic process, reliability indices for all the individual load points and for the system are obtained by recursively applying computational formula to reliability. The effectiveness of this approach is proved by examples.
