After the wind power yaw device detects the wind direction and enables the photovoltaic panel to be perpendicular to the wind direction through the automatic tracking device 3, the light pressure plate is inclined by the wind power, the spring between the light pressure plate and the pressure sensor is compressed, the elastic potential energy is increased, the pressure sensor detects pressure data and transmits the pressure data to the data processor, the data processor calculates the wind speed and further calculates a control signal to control the adjusting device 6 to adjust the angle and the height of the photovoltaic panel 4.

The mathematical simulation shows that when h/l sin theta =0.12, the output of the wind power plant is increased by 10% -14%, and the power generation of the first row of wind turbines is increased by 20% -25%; when h/l sin theta =0.24, the wind power plant can increase more yield, but the yield depends on the distance X between the wind wall and the wind turbine, and when h/X is more than or equal to 2 and less than or equal to 6, the power generation of the wind turbine is obviously increased.
