在采用逆流编号法[1] 的基础上 ,推导出了辐射型配电网的牛顿法潮流 ,直接给出了消去结果和回代结果的简洁表达式 ,并证明了此牛顿法的消去过程就是等值递推法[2 ] 的逆流等值过程 ,而回代过程恰是等值递推法的顺流递推过程 ,从而得出基于逆流编号法的配电网牛顿法潮流与等值递推法相一致的结论。

On the basis of the upstream labeling technique [1] Newton load flow for radial distribution network is proposed. The brief expressions for the results of the forward and backward processes are deduced. Also it certifies the forward process of this method is that of upstream equivalence of the Equivalent Recurrence Algorithm [2] (ERA) and the backward process is just that of the recurrence of the Equivalent Recurrence algorithm. Comparison between this Newton load flow and the ERA indicates that the Newton load flow for radial distribution network has wider application than the ERA. The great advantage of this Newton method lies in that it solves the problem of weakly-meshed power flow for the distribution network easily while other research work about this field focus on the compensating method. When there are quite a few meshes, the efficiency of the compensating method decreases.
