摘要

提出了一种并网双馈感应发电机转子侧磁场定向控制方案。为了控制转速，转差功率通过连接在转子侧的矩阵变换器作为工频转换器在电网和发电机之间交换。矩阵变换器(MC)的使用有助于提高整个DFIG系统的输入功率因数。基于定子磁链定向控制，在同步旋转参照系(d-q)下实现了整个系统的动态建模。该方案既能控制转子两端的有功功率，又能实现定子和转子之间的磁化电流共享。对整个方案进行了分析，并对各控制器的设计进行了讨论。在硬件实现之前，给出了仿真结果来验证所提出的方案。

Speed control of a grid connected doubly-fed induction generator system for maximum power point tracking with improved input power factor employing matrix converter as a slip power exchanger

The paper presents a scheme for the rotor side field oriented control of doubly fed induction generator (DFIG) connected to the power grid. To control the speed, the slip power is exchanged between the grid and the generator through a Matrix Converter connected to the rotor side as power frequency changer. Use of Matrix Converter (MC) helps to increase the input power factor of the overall DFIG system. Based on stator flux oriented control, the dynamic modeling of entire system is implemented in the synchronously rotating reference frame (d-q). The scheme is able to control the active power from the rotor terminals and it also allows the sharing of magnetizing current between stator and rotor. The analysis of the entire scheme and the design of various controllers are discussed. The simulation results are presented to justify the proposed scheme before implementing the scheme in hardware.
