Double-power-generation type intelligent self-adaptation vibration reduction wind turbine

Abstract

The invention relates to a double-power-generation type intelligent self-adaptation vibration reduction wind turbine. The double-power-generation type intelligent self-adaptation vibration reduction wind turbine comprises self-adaptation vibration reduction wind power blades, a hub, a cabin, a tower and a center control unit. Each self-adaptation vibration reduction wind power blade comprises blade damping piezoelectric webs, blade damping piezoelectric rib plates, double-curved-surface damping piezoelectric generators, blade porous regulation and control devices, blade vibration sensors, a skin, a blade root part and a blade tip part, wherein the blade damping piezoelectric webs are assembled at the positions, close to the middle portion of the blade, in the blade or / and other positions, the double-curved-surface damping piezoelectric generators are arranged in the blade, and the blade damping piezoelectric rib plates are assembled at the positions, close to the blade tip part and the blade root part, in the blade. The wind turbine comprises a wind power piezoelectric power generation work module and a wind power generator power generation work module. The purpose that the too large vibration of the blades is reduced to maintain the safety work of the blades can be intelligently achieved, the too large energy of blade vibration can be absorbed to generate piezoelectricity for power generation, and the power generating amount of the wind turbine is increased.

Description

technical field [0001] The invention relates to the technical field of wind power generation equipment, and more specifically relates to a dual-generation intelligent self-adaptive damping wind turbine. Background technique [0002] At present, the development of new renewable energy such as solar energy, biomass energy, wind energy and water energy has become inevitable, and wind power generation is the fastest growing energy source in the world, and it is also an emerging industry with the most commercial prospects. Wind power generation has become an indispensable and important field to solve the world's energy problems. [0003] Due to the harsh working environment of the fan for a long time, especially the blades are subject to various constantly changing loads, such as gusts, turbulence, wind shear, oblique wind, yaw, start-up brakes, gravity and inertial forces, ice and snow loads, etc. In particular, various vibrations caused by various constantly changing loads tha...
