摘要
针对少环配电网潮流计算需人工给定合环点和基本回路,实际应用不方便的缺点,提出自动搜索合环点及基本回路的方法。广度优先搜索连枝后,以连枝的首或末节点为合环点,将其分裂为2个节点,它们的电压差和合环电流小,在一定程度上减少了迭代次数;在广度优先搜索过程中,在增加标记每个节点的子节点的基础上,可快速搜索合环点分裂的两个节点到根节点的树枝,自动确定基本回路。不同规模的配电网验证了算法的实用性和准确性。
This paper presents an automatic loop node determination and fundamental circle algorithm to avoid manual deciding in weakly meshed distribution network.The start or end node of link obtained by breadth-first search is loop node.Then it is divided into two nodes.The voltage difference between the two nodes is little.So it can improve convergence efficiency and reduce the iteration number to some extent.The method marks the child node of each node in the process of breadth-first search.Then the method can rapidly search the tree branches from the two splitting node to root node.Thus the fundamental circle is automatically achieved.Different distribution systems are adopted to test the accuracy and practicality of the proposed algorithm.
