说明：  配电网辐射网前推回代潮流计算程序:前推回代法在配电网潮流计算中简单实用，所有的数据都是以矢量形式存储，因此节省了大量的计算机内存，对于任何种类的配电网只要有合理的R／X值，此方法均可保证收敛。而且，前推回代法的收敛阶数为一阶，因此它也具有较好的收敛稳定性。比较而言，前推回代法充分利用了网络呈辐射状的结构特点，数据处理简单，编程简单，没有复杂的矩阵运算，计算效率高，占用计算机的资源很少，具有较好的收敛性，广泛用于在实际配电网中，可称是求解辐射状配电网潮流问题的最佳算法之一。
(With forward and backward substitution flow calculation grid Radiation Network program: front and backward substitution method in the distribution power flow calculation is simple and practical, all the data are stored in vector form, thus saving a lot of computer memory, for any kind of distribution network, as long as there is a reasonable R/X value, this method can be guaranteed to converge. Moreover, forward and backward substitution method convergence order for the order, so it has a good convergence stability. Comparison, the forward and backward substitution method take full advantage of network radiating structural features, data processing, programming is simple, not complex matrix operations, computationally efficient, very few take up the computer' s resources, has better convergence , widely used in the actual distribution network is one of the best algorithm for solving the radial distribution power flow problem.)
