双馈风力发电机控制方法的分析研究

首先详细研究了风力发电系统中双馈电机的基本原理,在此基础上分析了双馈风力发电机的矢量控制和直接转矩控制两种控制方法。着重分析了两种控制方法的控制原理、控制过程。并根据两种控制方法的控制原理和控制过程得出双馈风力发电系统的矢量控制和直接转矩控制的控制原理图。最后对所研究分析的两种方法的优缺点进行比较。提出了该领域目前存在的一些问题。为该领域的研究提供借鉴。

Research of Control Methods for Doubly-fed Wind Generator

In this paper,the basic principle of double-fed motor in the wind power generation system has been studied.In this based,two kinds of control methods of double-fed wind generator vector control and direct torque control have been analysised.Focused on analysis of control theory and process of this two kinds of control methods.Then according to control theory and process,we could get the control principle drawings of double-fed wind generator vector control and direct torque control.Finally,we compare the advantages and disadvantages of the two methods.At the same time we put forward the existing problems in this area,it can lay the foundation for the future research in this area.
