Description

(1) Technical field [0001] The invention relates to a wind power generating device and a method thereof for forming an artificial wind field by utilizing the pressure difference of atmospheric altitude. (2) Technical background [0002] With limited energy resources dwindling and the environment deteriorating, the development and utilization of renewable energy such as wind power has attracted increasing attention. However, the current wind power technology is still at the primary stage of relying on natural conditions Due to factors such as large changes and special site topography, the investment in wind power generation is large, the output of a single unit is low, the actual power generation time is short (only 1 / 4 of the annual power generation time), and the wind speed per hour per unit is unstable. , when the wind force changes slightly or the load changes, the torque balance of the rotor will be broken. When the wind torque is greater than the load torque, the rotor ...
