摘要
电网规模日渐增大加之风力发电技术不断进步,风电场接入地区电力系统时,电网动态安全问题就越来越受到关注,其中时域仿真研究电力系统的动态特性是一个行之有效的方法。引入了一种以Matlab语言为基础编写的仿真软件PSAT,集绘图、分析以及计算为一体的电力系统分析软件包来研究电网动态安全问题。文中首先简要概述PSAT的功能及特点,然后结合1个典型风电场接入电网的模型进行时域仿真分析,说明了风电场接入电力网络时的网络模型、参数的设置以及仿真图形的绘制等问题。
With the rapid increase of power grid and constant progress of wind power technology, more attention is paid to the dynamic security of the power grid when wind farm is connected to regional power system.In this aspect, time domain simulation is one of the most important methods to research the dynamic characteristics of power system.This paper introduces a novel power system analysis software package PSAT that bases on Matlab language, containing drawing, analysis, calculation and data management, to research the dynamic security of the power grid. Firstly,the paper briefly expounds the function and characteristics of the PSAT. Then, this paper makes a time domain simulation analysis combined with a typical example of the power grid to be connected with the wind farm, and shows the problems of the network model of the power grid to be connected with the wind farm, its parameter setting and the drawing of simulation graphics.
