电力系统潮流分析的牛顿–拉夫逊法计算
Newton-Raphson Method for Power Flow Analysis of Power System

潮流计算主要是根据一个给定的电网架构、参数以及其它的条件而来确定一个电力系统的各个组成部分在其中的稳定运行状况参数。本文通过研究牛顿–拉夫逊法原理，将其引入潮流计算建立了电力系统模型与算法，然后以3机9节点为具体实例，应用牛顿–拉夫逊法程序计算，再利用Simulink仿真中自带电力系统模型计算，通过两种方法潮流计算结果一致，表明牛顿–拉夫逊法在处理潮流计算上结果良好。
Power flow calculation is mainly based on a given grid architecture, parameters and other condi-tions to determine the stable operation parameters of various components of a power system. By studying the principle of Newton-Raphson method, this paper introduces it into power flow calcula-tion and establishes the power system model and algorithm. Then, taking three machines and nine nodes as a specific example, using the Newton-Raphson method’s program to calculate, and then using the power system model in Simulink simulation to calculate. The results of the two methods are consistent, which shows that the Newton-Raphson method has good results in dealing with the power flow calculation.
