双驱风力发电机并网控制的仿真研究
摘要
随着社会的发展,对电能的需求也越来越多,再加上化石能源日益短缺,可再生能源
发电技术的重要性和紧迫性也日益凸显。其中,风能作为一种清洁环保的可再生能源,受
到世界各国的广泛关注。
本文应对社会需求,采用双驱风力发电机这一新型电机,以有功功率和无功功率的解
耦控制为目标,利用 MATLAB/Simulink 软件搭建两套不同的电机并网的稳态模型,并分
别进行测试,最终选择定子磁链定向的矢量控制方法,解决了有功功率和无功功率的耦合
问题,并由此成功搭建了功率跟踪器模型,使得双驱风力发电机并网系统实现功率跟踪的
功能。
本文研究的主要内容如下:
1、深入研究双驱风力发电机结构及运行原理,弥补前期双驱电机仿真模型的不足,
在与转子同步的两相旋转坐标系下,建立通用性较强的双驱电机并网稳态模型。由仿真结
果证实本模型不能通过调节主、副风轮的转速来实现有功功率与无功功率的解耦控制。
2、针对有功功率和无功功率的耦合情况,采取定子磁链定向的坐标变换方法,搭建
双驱电机并网稳态模型。由仿真结果验证本模型能够通过调节 d、q 轴电流来实现有功功
率与无功功率的解耦控制。
3、在分析研究双驱风力发电机功率特性基础上,运用定子磁链定向的矢量控制方法,
设置功率跟踪控制器。由仿真结果证实功率跟踪器工作正常、双驱风力发电机并网稳态运
行的功率跟踪效果比较理想。

CONTROLLING AND SIMULATION OF THE
GRID-CONNECTED DOUBLE-DRIVER WIND GENERATOR
ABSTRACT
With the development of society, more and more power will be demand, coupled with the
increasing shortage of fossil energy, and the importance and urgency of renewable energy
generation technologies is also increasing. Wind power as a kind of clean and renewable
resource, has brought worldwide attention.
This paper meet the needs of society, with this new dual-drive wind generator motor to the
active and reactive power decoupling control as the goal, using MATLAB/Simulink software to
establish two different sets of grid-connected steady-state model and testing each respectively.
We chose the stator flux-oriented vector control method to solve the coupling problem of active
power and reactive power, and thus essfully built the power tracker model, making the
grid-connected system of double
