文档介绍：摘要
潮流计算的目的在于:确定电力系统的运行方式;检查系统中各元件是否过电压或过载;为电力系统继电保护的整定提供依据;为电力系统的稳定计算提供初值,为电力系统规划和经济运行提供分析基础。
牛顿迭代法(Newton's method)又称为牛顿-拉夫逊方法(Newton-Raphson method),牛顿--拉夫逊法(简称牛顿法)在数学上是求解非线性代数方程式的有效方法。其要点是把非线性方程式的求解过程变成反复地对相应的线性方程式进行求解的过程。即通常所称的逐次线性化过程。MATLAB是一种交互式、面向对象的程序设计语言,广泛应用于工业界与学术界,,通过建立矩阵的修正方程来依次迭代,逐步逼近真值来计算出电力网的电压,功率分布。
本文采用牛顿-拉夫逊法解算电力稳态潮流,用手算和计算机算法对其进行设计。使用MATLAB软件进行编程,在很大程度上节省了内存,减少了计算量。通过对本题计算我们了解了一些工程计算和解决工程问题的方法。

ABSTRACT
The Power putation's goal lies in: Definite electrical power system's movement way; In checkout system various parts whether overvoltage or overload; Provides the basis for the electrical power system relay protection's installation; Provides the starting value for electrical power system's putation, is the electrical power system plan and the economical movement provides the analysis foundation.
The Newton iteration method (Newton's method) is called Newton - Rough to abdicate the method (Newton-Raphson method), Newton--Rough abdicates the law (. Newton law) is solves the misalignment algebraic equation in mathematics the efficacious device. Its main point is turns the misalignment equation solution process carries on repeatedly to the corresponding linear equation the solution the process. Namely usually called linearized process gradually. MATLAB is one kind interactive, the object-oriented programming language, widely applies in the industrial world and the academic circle, mainly uses in the matrix operation. Uses the repetitive process, iterates in turn through the establishment matrix's modified equation, approaches the true value to calculate electric work's voltage gradually, the power distribution.
This article uses Newton - Rough to abdicate the law resolving electric power stable state tidal current, with the hand calculated that carries on the design with puter algorithm to it. Uses the MATLAB software to carry on the programming, to a great extent
