Abstract

The aim of this invention focuses on the development of a grid-connected wind generation system and its maximum-power-extraction control method. The wind turbine is used to extract the ac power through the blowing wind. Then, the ac power is rectified through a rectifier and a filter to a stable dc power for the utilization of a later grid-connected full-bridge inverter. In order to increase the efficiency of the wind power, a maximum-power-extraction method is necessary to hold the wind generation system operating on the maximum-power-point under variable wind speeds. In previous works, the maximum-power error driven (MPED) control is investigated for capturing maximum powers from wind power, and it forces the wind power closing to the maximum-power-point by changing the direction of the power command. However, the settling time of the MPED control with hundreds of seconds to achieve the corresponding maximum power renders it ineffective to a constantly changing wind speed in practice. In this invention, a maximum-power-extraction method including a maximum-power differential speed (MPDS) control is designed for accelerating the maximum-power-extraction speed and reducing power losses. Moreover, an adaptive total sliding-mode control (ATSMC) system is introduced by way of switching four power semiconductors in the full-bridge inverter to maintain the output current of the inverter in synchronization with the utility voltage to achieve the unity power factor for utility-power grid connection.
