Title:
AIR JET WIND TURBINE GENERATOR
Document Type and Number:
WIPO Patent Application WO/2012/055313
Kind Code:
A1
Abstract:
An installation method for an air-jet wind turbine generator comprises the following steps: an air-jet (3) is installed at the end of each turbine blade (2) of the wind turbine. The air-jets (3) are provided perpendicular to the turbine blades (2) and are capable of outputting a recoil velocity that is also equal to or within ± 20 degrees of the linear velocity of the turbine blade ends. The air-jets utilize a counteracting force to accelerate or decelerate each turbine blade, and the counteracting force can compensate the rotating speed of the wind turbine either positively or negatively. The air-jets can be axial fans or any airflow or airburst device. The above layout can improve the efficiency of wind turbine generators, and can automatically adjust the air volume and speed of the air jets according to a set speed of the wind turbine via a speed sensor, thereby constantly maintaining the wind turbine generator rotating speed at the set speed. Thus the stability of the wind turbine generator rotating speed is ensured, generating high voltage three-phase alternate current electricity that can be directly fed into the grid. Also disclosed is an air jet wind turbine.
