摘要
本文提出了一种分块降阶潮流算法 ,该算法通过适当节点编号将辐射形网络与环网分开 ,降低复杂网络的阶数 ,充分利用辐射形网络导纳矩阵主对角占优的特点 ,采用追赶法求解大量的辐射形网络方程 ,仅用牛顿—拉夫逊法潮流算法求解阶数不高的复杂网络方程 ,进而达到提高计算速度和数值分析稳定性 ,减少占用计算机内存的目的。该算法通过典型算例进行了验证 。
In this paper,the classified and deordered power flow algorithm of complex distribution network was presented.With the algorithm,the computational speed and the stability of numerical analysis can efficiently be raised,the computer storage can be lowered by properly coding radiative network node numbers and colsed network node numbers separately,and by solving radiative network equations in the large majority by three diagonal algorithm,by solving colsed network equations in the minority by Newton Raphson method.The example compared with Newton Raphson method and Fore and Back Iteration algorithm was given.
