摘要
针对恒速恒频风力发电机控制困难和易受电网谐波影响的问题,提出了一种基于Buck电路的矩阵变换器的风机直接转矩控制方法.利用Buck电路简化传统的三相-三相矩阵变换器控制策略来构造三相-单相矩阵变换器,将该矩阵变换器应用到永磁直驱风力发电机的直接转矩控制系统中,并使用反馈线性化法来简化系统的控制策略.利用Matlab软件的仿真测试结果表明,所设计的矩阵式变换器能显著提高系统的动态响应性能,且提出的控制策略具有良好的稳定性和鲁棒性.
Aiming at the control difficulty of constant-speed and constant-frequency wind turbine as well as the easy affection by the harmonics of power grid,a direct torque control method for a fan based on Buck circuit matrix converter was proposed. The Buck circuit was used to simplify the control strategy of traditional three phase-three phase matrix converter and to establish a three phase-single phase matrix converter. The proposed matrix converter was applied in the direct torque control system of permanent magnet direct driving wind turbine. In addition,the control strategy of the system was simplified with the feedback linearization method. The results of simulation test with the Matlab software show that the designed matrix converter can significantly improve the dynamic response performance of the system,and the proposed control strategy has good stability and robustness.
