基于MATLAB的电力系统复杂潮流分析

摘要

电力系统潮流计算是电网分析的基础应用，是对复杂电力系统正常和故障条件下稳态运行状态的计算。给定电力系统的网络结构、参数和决定电力系统运行状况的边界条件，，确定电力系统运行的方法之一是朝流计算。

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，主要用于矩阵运算.采用迭代法，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。

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

Power Flow Analysis Grid computing is the basis of applications, the complex power system under normal and fault conditions for the calculation of steady state operation. Given the power system network structure, parameters and decisions operation of the power system boundary conditions, to determine the method of operati on of the power system is one of North Korea flow calculati on.

PQ decompositi on method is the form of polar coord in ates Newt on - the widening trend of a simplified calculation method. P-Q decomposition method adopted by the specific characteristics of the power system ariysis, Newt on ' s Law of

the Jacobian matrix formula has effectively simplified and improved. As a result of these simplified formula that invoIves only the coefficient matrix, the balance of power has not cha nged node equati ons and the conv erge nce criteri on, becausethe results will not reduce the accuracy.

MATLAB is an in teractive, object-orie nted program ming Ian guage, widely used in industry and academia, mainly for matrix calculation. Using iteration, the ame ndme nt through the establishme nt of matrix iterative equatio n to tur n, gradually moving towards a true value to calculate the voltage electricity grid, power distributio n.

Use MATLAB software program ming, sav ing memory to a large exte nt, reduce the amount of computation. By this calculation we understand that a number of engin eeri ng calculatio n and solve engin eeri ng problems
