摘　　要：在分析现有配电网潮流计算方法的基础上,通过对传统的前推回代法加以改进,提出了一种适用于辐射配电网潮流计算方法,具有实用性.该方法充分利用辐射配电网络的结构特点,对分支、节点和支路编号进行优化,它直接采用支路阻抗参数进行计算,不需要形成节点导纳矩阵和进行三角矩阵变换,简单的处理代数方程就可以计算节点电压和功率分布,使得程序实现起来更加高效、准确.根据提出的算法编制了配电网络潮流程序,用算例验证了算法和程序的可行性.On the basis of analyzing the current techniques for power flow calculations of distribution network, by improving the traditional forward and backward substitution method, a calculation applied for the reliable distribution network is presented, which has practicability. This method makes full use of the structural features of the reliable distribution network, optimizes the numbered branches, nodes and loads, uses directly branch impendance parameter to calculate, and doesnt need formming bus admittance matrix and converting triangular matrix. Simple dealing with algebra equations can calculate node voltage and power distribution, which makes the program more efficient and exact. A program of distribution network power flow is developed according to the proposed algorithm, and the feasibilities of the proposed algorithm and program are verified by the case.
