MATLAB+STATCOM含风电的电力系统稳定性分析

摘要风能的利用率和风电的发展在近 20 年中取得了巨大的进步与发展，但是就目前水平来讲，大规模的风电并网仍会对电网正常运行带来严重影响，最为棘手的是这样的问题会使得电网无功功率发生波动，达到一定程度时，电网电压可能崩溃。所以，对风电并网无功补偿及电压稳定的分析及探讨极具现实意义。本文分析的主要内容如下：70361

(1)研究普通异步风电机组及双馈式风电机组的运行原理、数学模型。 (2)风电接入对电力系统无功功率及电压的影响。 (3)通过对电压稳定性能的分析，分别得出电压及无功恢复方法。 (4)分析不同的电网无功补偿方法，应用 MATLAB 进行仿真，以其中的 SVC

Power system stability analysis including wind power

Abstract Utilization of wind energy and wind power development has made great progress and development in the past 20 years, but the current level in terms of large-scale wind power will have serious impact on the normal operation of the power grid, the most difficult is this problems will make reactive power grid fluctuations, reaches a certain level, the grid voltage may crash. Therefore, analysis of wind power and reactive power compensation and voltage stability Discussion of great practical significance. The main contents of this paper are as follows:

(1) Operating Principle ordinary asynchronous wind turbines and doubly- fed wind turbine, mathematical model.

(2) Wind Power on power system reactive power and voltage.

(3) Based on the voltage stability analysis were obtained voltage and reactive power recovery methods.

(4) analysis of different reactive power compensation grid method, using MATLAB simulation in which the SVC and STATCOM as compensation means are listed separately on the grid voltage balance.

Key Words: wind power voltage stability reactive power compensation SVC STATCOM MATLAB
