基于Matlab的远距离输电线的数字仿真

Digital Simulation of Long-distance Transmission Line Based on Matlab

Simulink是Matlab中强大的动态仿真工具,它具有构造模型简单、实现系统控制容易、修改参数方便、界面友好、功能强大等优点,成为动态系统建模与仿真应用最广泛的软件包之一。将Simulink用于电力系统的仿真研究近几年逐渐成为人们研究的热点。文中根据双回远距离高压传输线模块的数学模型,并利用Simulink的数学模块,提出了一种基于Mat labSimulink软件包的仿真方法,实现对双回传输线正常状态的数字仿真。仿真结果表明,所提出的模型和方法是正确的,实现起来简洁、方便。

Simulink is a software package for modeling,simulating,and analyzing dynamical systems.It supports linear and nonlinear systems,modeled in continuous time,sampled time,or a hybrid of the tow.Systems can also be multirate, i.e,have different parts that are sampled or updated at different rates.For modeling,Simulink provides a graphical user interface(GUI) for building models as block diagrams,using click -and-drag mouse operations.Being used in the practical research of simulating the electrical power system,Simulink become heated gradually in the last few years.This text presents a simulation method based on the tools of Matlab Simulink to realize the digital simulation of the normal state of double transmission line in the light of the mathematical model of double transmission line model and applying mathematic model of Simulink.The result of simulation shows that the model and method are correct and this method is concise and convenient.
