The invention discloses a wind turbine tower surface pressure measuring device and a wind turbine tower surface pressure measuring method suitable for a wind tunnel experiment. The wind turbine towersurface pressure measuring device comprises a supporting frame and a sleeve, wherein the supporting frame comprises a pedestal, a bearing bracket, and a top flat plate. The wind turbine tower surfacepressure measuring method comprises the following steps of: installing a wind turbine and a supporting frame in a wind tunnel, and installing a sleeve around the supporting frame; forming pressure measuring holes in different sections of the sleeve, and connecting the pressure measuring holes to a pressure scanning valve; installing a Hall sensor, a rectifier bridge and a direct-current load; starting the wind tunnel; collecting a current wind speed and surface pressure of the wind turbine tower under different rotating speeds and static states; changing the wind speed of the wind tunnel, andcarrying out repeatedly measurement after the wind speed of the wind tunnel is stable until all working conditions to be measured are measured. The wind turbine tower surface pressure measuring deviceand the wind turbine tower surface pressure measuring method are low in design cost and convenient to install, and have important engineering significance for accurate prediction of the aerodynamic load of the wind turbine tower in the rotating and static states.
Description
technical field [0001] The present invention relates to the field of wind tunnel experiments and performance testing of wind turbines, in particular to a wind turbine tower surface pressure measurement device and method suitable for wind tunnel experiments Background technique [0002] Wind power is currently the most widely used new energy power generation method. As countries around the world pay more and more attention to energy security, ecological environment and other issues, accelerating the development of wind power has become the general consensus of the international community to promote energy transformation and development. [0003] The horizontal axis wind turbine is one of the most effective wind energy conversion devices. It is mainly composed of a hollow steel tower and soft blades. When the wind turbine is running, the rotation and flow of the blades affect the flow field around the tower, resulting in The sharp change of wind speed and the change of flow fi...
