Abstract

The invention discloses an offshore floating type wind turbine generator with an energy storage device, and an electric energy absorption method. The offshore floating type wind turbine generator comprises a fan, a tower drum, a box body structure and a plurality of air storage tanks, wherein the fan, the tower drum and the box body structure are sequentially connected from top to bottom, the airstorage tanks are arranged on the periphery of the box body structure at equal intervals, a compressor and a micro turbine are arranged in the box body structure, and the compressor is communicated with inlets of the air storage tanks; outlets of the air storage tanks are communicated with a working medium inlet of the micro turbine, and the air storage tanks are filled with compressed air; an anchoring support is arranged on the periphery of the box structure, the anchoring support is connected with an anchoring device through a catenary, and the anchoring device is fixed to the seabed; a balance weight is arranged in the box body structure; the electric energy input end of the compressor is connected with the electric energy output end of the wind turbine generator; and compressed air inthe air storage tanks serves as an energy storage medium, meanwhile, and also can provide buoyancy for the fan to reduce the acting force of stormy waves on the fan and keep the fan stable, and meanwhile electric energy of the wind turbine generator can be absorbed.

Description

technical field [0001] The invention belongs to the technical field of offshore wind power, and in particular relates to an offshore floating wind turbine with an energy storage device and an electric energy consumption method. Background technique [0002] Compared with onshore wind power, offshore wind power has the advantages of abundant wind energy resources, suitable for large-scale development, and no visual and noise pollution. In the offshore, due to the shallow water depth, the wind turbine adopts a fixed foundation. However, in deep sea areas, the cost of fixed foundation construction is too high, and various problems such as fatigue and deformation are prone to occur. Therefore, new types of floating wind turbines will be used for deep sea wind power. [0003] As a kind of renewable energy, wind energy also has the characteristics of energy instability and poor grid friendliness. Energy storage is an effective means to solve the intermittency problem of renewabl...
