| 摘 要： | 直接转矩控制技术(DTC)已广泛应用于感应电动机的调速控制领域，并获得了良好的控制效果.感应电动机的直接转矩控制主要是在工频附近，双馈发电机的直接转矩控制主要工作在低频区域，而直接转距控制技术的低频特性是一个研究热点.对变速恒频双馈风力发电机的直接转矩控制技术进行了理论分析，阐述了它的工作原理和系统结构，推导出有关控制方程，给出了具体的控制框图，并在此基础上利用MATLAB/SIMULINK进行了仿真研究.仿真结果证明，所设计的控制系统可以实现对输入机械功率曲线的有效跟踪，说明理论分析和提出的控制策略是可行的.

| Abstract: | Direct torque control DTC technology is widely used in variable speed operation of induction motors and the control effect is good.DTC of induction motors is employed around the industrial frequency, but the doubly-fed generator works at lower frequencies,so that the lower frequency characteristic of DTC is one of research hotspots.Therefore,the DTC technology applied to wind generation system was theoretically analyzed.The operation principle and system structures were introduced, the related control equations were deduced,and control diagram was also given.The simulation by MATLAB/SIMULINK was conducted.The result verifies that the designed control system can realize the track to the input mechanism power curve and shows the proposed theories and scheme are feasible. |
