A Simplification Method of Power Flow Calculation Based on Newton-Raphson

根据电力系统的运行特征提出新的假设,改进了牛顿-拉夫逊潮流算法中修正方程式的建立,继而对直角坐标下牛顿-拉夫逊潮流算法的雅可比矩阵进行简化,并提出用最优乘子解决病态系统.13节点算例计算结果表明,该法具有良好的收敛性,可减少内存占有量并具有较高的计算速度.

According to the operation characteristics of power system, several new assumptions are proposed and then a method of simplify Jacobian matrix is used to rectangular coordinate Newton-Raphson. The paper suggests that we can solve ill-conditioned power systems by optimum multiplier. This improved algorithm has been tested on the 13- node systems. The results show that it has better convergence, and economizes the computer memory and has more fast calculation speed.
