摘要
在分析现有配电网潮流计算方法的基础上,针对辐射型配电网潮流计算中广泛采用的前推回代法需要复杂编号的情况,提出了一种不需要对配电网重新编号的分层前推回代算法。该算法将网络支路按层次进行分类,得到支路层次矩阵,从而可以不必对节点和支路重新编号计算支路功率损耗和各节点电压。并且由于同一层次的支路功率之间没有前后关联,因此同层次内完全可以实现功率或电压的并行计算,对于大型配电网络,可以提高其计算速度。最后用算例证明了方法的有效性。
On the basis of analysis on existing power radial distribution network, a layer forward and backward substitution method without renumbering the distribution network is put forward, which is widely used to power flow computation. The computation will classify the branches by layers, get the layer matrix, so that no renumbering of the nodes and branches is needed, no computation of the branch power loss and voltage at different nodes is needed. Moreover because there is no association between the branches at the same layer, so parallel computation of the power and voltage can be carried out at the same layer. As for large-scale distribution network, the computation speed can be enhanced. In the last, examples are used to show the validity of the method.
