| 摘 要： | 针对辐射状配电网的结构特点,应用前推回代法进行潮流计算,以广度优先搜索策略为理论基础,通过广度优先搜索遍历并借用ADT栈形成网络层次结构,来确定前推回代的节点顺序,形成一种实用的配电网潮流计算方法。该方法可以处理多分支辐射网,无需复杂的网络编号、不用形成导纳矩阵,而且迭代次数少、结果精确。该算法已在实际城区配电网应用,运行良好。

| Abstract: | According to the structural character of radial distribution networks,the back/forward sweep method is applied to compute the power flow.Based on breadth-first search,through the Breadth-First search and the ADT stack,the layer structure and the node order of back/forward sweep are formed.Then a practical power flow algorithm has come into being completely.The new algorithm can process radial network with multiple branches,without complex network labeling or admittance matrix calculating.Furthermore,its loop is few and its result is precise.The algorithm has been applied in the distribution network of the city zone and run in good conditions up to now. |
