本文提出了风力发电系统的无传感器输出功率最大化控制。在所提出的系统中，永磁同步发电机（PMSG）用作变速发电机。根据发电机速度适当控制发电机扭矩，因此通过所提出的 MPPT 控制方法，风力涡轮机的功率稳定在最大功率点，其中不需要风速信息。此外，通过最佳电流矢量控制获得最大可用发电功率。根据发电机速度和所需扭矩对 PMSG 的电流矢量进行优化控制，以便在考虑电压和电流约束的情况下最大限度地减少 PMSG 的损耗。所提出的风力发电系统可以在没有诸如风速检测器和位置传感器之类的机械传感器的情况下实现。几个实验结果表明了所提出的控制方法的有效性。 © 2004 Wiley periodicals, Inc.

This paper proposes sensorless output power maximization control of a wind generation system. A permanent magnet synchronous generator (PMSG) is used as a variable speed generator in the proposed system. The generator torque is suitably controlled according to the generator speed and thus the power from a wind turbine settles down on the maximum power point by the proposed MPPT control method, where the information on wind velocity is not required. Moreover, the maximum available generated power is obtained by the optimum current vector control. The current vector of PMSG is optimally controlled according to the generator speed and the required torque in order to minimize the losses of PMSG considering the voltage and current constraints. The proposed wind power generation system can be achieved without mechanical sensors such as wind velocity detector and a position sensor. Several experimental results show the effectiveness of the proposed control method. © 2004 Wiley Periodicals, Inc.
