摘要

风力发电系统中的转速传感器常常会带来一些不利的影响。文中介绍了一种双馈风力发电机的无速度传感器的控制方法

利用风电机组转动惯量大

速度变化慢的特点

通过测量转子的感应电动势

控制转子侧变流器给转子注入相应频率与相位的电流

从而控制电机的转矩与无功。文中推导了电机的控制方程式

给出了控制框图。通过仿真与实验

验证了该方法可以用于双馈风力发电机的控制。

Abstract

A control method of DFIG wind power system is discussed in this paper. Since the large rotational inertia of the wind turbine

and the low speed variation of it

the speed of wind turbine can be seen as constant in a short interval. By measuring the EMF of rotor

control the rotor side inverter injecting the current into rotor with proper phase and frequency

the power and the reactive power of the machine can be controlled. Control equation and block are given. Simulation and experimental result verify the rightness of the method.
