Control design of a Synchronous Generator of a horizontal axis wind turbine

This paper presents the control design for the wind turbine in a hybrid photovoltaic/wind system. A Permanent Magnet Synchronous Generator (PMSG) connected to the wind turbine converts wind power into electricity. The speed is estimated without sensors by a PLL (Phase locked loop) algorithm. The proposed Maximum Power Point Tracking (MPPT) gives the speed reference based on the turbine power versus speed curve. A boost converter circuit is used to control the generator speed by changing the DC input voltage. PLECS Simulation Software and experimental results verify the performance of the proposed method in simulation.
