Abstract
The invention discloses a wing section control method and device with a lifting force type vertical axis wind turbine generator, and the method comprises the steps that a function expression constructed for the wing section chord length of the lifting force type vertical axis wind turbine generator is obtained, aerodynamic design parameters at least comprise the incoming flow wind speed facing a transverse horizontal wing section and the wing section attack angle of the transverse horizontal wing section, and the function expression is constructed for the wing section chord length of the lifting force type vertical axis wind turbine generator; the vertical axis blade height, the vertical axis wind wheel diameter and the vertical axis unit efficiency; the current incoming flow wind speed is calculated through the function expression, and the chord length value of the first wing section is obtained; the first wing section chord length value is used for conducting performance testing on the lift type vertical axis wind turbine generator, a performance testing result is obtained, and under the condition that it is determined that the testing result is used for indicating that the unit performance of the lift type vertical axis wind turbine generator passes testing, the transverse horizontal wing section is replaced with a target transverse horizontal wing section with the first wing section chord length value, and controlling the target transverse horizontal wing section to rotate according to the current incoming flow wind speed.
