Several Approaches to the Method of Newton - Raphson Power - Flow Algorithm in Rectangular Coordinates

对直角坐标型的牛顿－拉夫逊法潮流计算作了一些新的探讨，其中包括电压初值的选择、雅可比矩阵元素的简化．为完成这些简化，不但提出了对高斯－塞德尔法的改进算法，还提出了几种假设，这些假设也可以用在电力系统计算的其它方面．并以一个５结点的网络为例进行了详细地计算分析、比较．

Several new approaches to the method of Newton - Raphson power - flow algorithm in rectangular coordinates are presented, which include the choices of initial voltage values and the simplicities of Jacobian matrix elements. In order to finish these simplicities, not only is the improved algorithm of Gauss - Seidel method studied, but also three kinds of assumptions are proposed. These assumptions can also be used in other calculations of power systems. A five - bus system is taken as an example, and detailed analyses and comparisons are made.
