基于Matlab的电力系统潮流仿真计算 摘要：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，同时在数值分析、自动控制模拟、数字信号处理、动态分析、绘图等方面也具有强大的功能。通过M语言，可以用类似数学公式的方式来编写算法，大大降低了程序的难度并节省了时间，从而可把主要的精力集中在算法的构思而不是编程上。 传统的潮流计算程序缺乏图形用户界面，结果显示不直观，难于与其他分析功能集成，网络原始数据输入工作量大且易于出错。Matlab潮流计算研究近年来得到了长足的发展。针对这一现状结合电力系统的基本特点，以牛顿—拉夫逊法潮流计算方法为例，对IEEE-6BUS标准试验系统的潮流计算进行仿真,提出了基于Matlab的电力系统潮流仿真计算。它大大提高了计算速度，占用内存少；计算结果有良好的可靠性和可信性；适应性好，即能处理变压器变比调整，系统元件的不同描述和与其它程序配合的能力强。 关键词：电力系统潮流计算;　MATLAB仿真;　牛顿—拉夫逊法潮流计算;　面向对象 Power system of simulation Trend based on the Matlab Abstract: Matlab is an interactive, object-oriented programming language, widely used in industry and academia, mainly used for matrix, and the numerical analysis, automatic control simulation and digital signal processing, dynamic analysis, drawing are powerful functions. Through the M language, can use similar mathematical formula, the way to write the algorithm greatly reduces the programs difficulty and saves time, thus, can put the main focus on the conception and not programming algorithm. The traditional flow calculation program lacks the graphical user interface, the results showed that dont intuitive, but difficult to and other analysis function integration, network raw data input workload big and easy to go wrong. Matlab research in recent years obtained the flow calculation farsighted development. With respect to this current situation with the basic characteristics of electric power system, with Newton - rafer Johnson method for example, flow calculation method of IEEE 6BUS standard test system - flow calculation, and simulation was proposed based on Matlab simulation calculation of electric power systems tide. It greatly improves the calculation speed, less memory; Calculation results have good reliability and credibility; Good adaptability, namely can handle transformer adjustment, system components with different description and the ability with other programs. Key words: electric power system flow calculation; MATLAB simulation; Newton - rafer Joh
