Research Method of Wind Energy Control based on Vertical Axis Wind Turbine
A wind power generation control strategy, which is suitable for transmitting power to the grid, is proposed in allusion to the unstable characteristic of the output power. This control strategy captures wind power from a vertical axis wind turbine(VAWT), and a back-to-back PWM converter is applied to control the output power from permanent magnet synchronous motor(PMSM) in order to make sure the wind power can be transmitted to the grid safely. Due to the characteristic of the traditional control method that the power factor is not the optimal by the side of motor, this paper presents a control method of unit power factor, so that the voltage and the current are controlled to the same phase by the side of motor as well as the voltage and the current are controlled to the opposite phase by the side of power grid in order to ensure the output reactive power is zero. The simulation results based on Simulink validates the effectiveness of the proposed control strategy.
