直驱永磁风力发电系统无位置传感器最大功率点跟踪控制

为了从变化的风中获得最大输出功率,当风速变化时发电机的转速也必须跟着变化以维持最佳叶尖速比.因此,转子位置和风速的信息是必不可少的.然而,采用转子位置和风速传感器将降低系统的可靠性和增加成本.因此,本文提出一种新的方法,即采用观测器来观测转子位置和风速,而无需转子位置和风速传感器.仿真结果证明了这个控制方法的可行性.

Maximum Power Point Tracking Control for Direct Driven Permanent Magnet Wind Generation System Without Position Sensors

To obtain maximum output power from changing wind,the generator speed must vary with the wind velocity to maintain optimal tip speed ratio as wind velocity changes,so the information of rotor position and wind velocity are essential.However,using rotor position and wind velocity sensors reduces the reliability and increases the cost of the system.Hence,using observer instead of wind velocity and rotor position sensors to obtain rotor position and wind velocity for wind power generation system is proposed in...
