摘　　要：结合配电网特有的辐射状特点,提出了一种新的基于节点分层的配网潮流前推回代方法。该方法利用配网支路及其节点参数所形成的节点-节点关联矩阵推导出节点分层矩阵及其对应的上层节点矩阵,再根据所形成的分层矩阵及其对应的上层节点矩阵利用前推支路电流和回代电压进行计算。通过对算例的编程计算,结果表明所提的算法有效、快速及实用。Combined the unique characteristics of the radial of distribution network,this paper proposes a novel back/forward sweep distribution load flow algorithm based on the node-layer.By using the matrix of node-layer and the matrix of the up-node,according to the parameters of node and branch,the algorithm computes the current of the branches and the voltage of node of the network.An example of the distribution network is compute d.The result indicates that the algorithm proposed is valid,fast and practical.
