Abstract

To investigate the characteristics of a cycloid gear pump which is used as the accelerating pump in the wind power, a flow mathematical model was built, the advanced modeling environment simulation (AMESim) hydraulic model of wind turbines was established, and the effectiveness of the model is verified by the experiments. Based on the AMESim model, the flow characteristics of the wind turbine under the steady and unsteady wind speeds were investigated. The results show that, at low steady speed, the pulsation rate of flow pulsation in the cycloid gear pump decreases with the increase of rotational speed; and the lower the rotating speed is, the less steady the cycloid gear pump runs. Under the unsteady wind speed, the variation trend of output flow of the cycloid gear pump is basically consistent with that of the wind speed; the fluctuation frequency of the flow is greater than that of the speed. Meanwhile, due to the flow fluctuation of the cycloid gear pump, the mechanical energy with sudden change can be converted into the soft hydraulic energy, which is more conducive to the wind power. The research also proves that the cycloid gear pump can be used as the accelerating pump in the wind power generation system.
