Large wind turbine generator system with double wind wheels

Abstract

The invention discloses a large wind turbine generator system with double wind wheels, belongs to the field of generators, and aims at solving the problems of low unit capacity, high generator system investment, low generating capacity and the like of the existing wind turbine generator system with a single wind wheel. The large wind turbine generator system with the double wind wheels comprises a tower barrel, a cabin seat, the wind wheels, blades, transmission devices and a generator, wherein two groups of wind wheels, blades, transmission devices are provided respectively, and symmetrically arranged at the two sides of the generator respectively, and the first-group transmission device comprises a first main shaft, a first coupling, a first low gear shaft, a first gearbox, a first high-speed shaft and a first elastic coupling which are sequentially connected; and the second-group transmission device comprises a second main shaft, a second coupling, a second low gear shaft, a second gearbox, a second high-speed shaft and a second elastic coupling which are sequentially connected, and the first elastic coupling and the second elastic coupling are connected with double output shafts at the two ends of the generator respectively. The wind turbine generator system with the double wind wheels, which is disclosed by the invention, is safe and reliable in running, and easy to manufacture, install and maintain.

Description

technical field [0001] The invention belongs to the field of generators, and in particular relates to a large-scale double wind turbine wind power generator set. Background technique [0002] Clean energy is one of the important energies needed by countries in the world today, such as solar power and wind power, etc., which have developed very rapidly in recent years. Both solar power generation and wind power generation in our country are developing very fast, supplementing the energy shortage, and have achieved great results and great achievements. At the same time, the energy investment and construction of solar energy and wind energy also have the problems of large investment and low power generation of a single machine, especially wind turbines, single-wheel wind turbines with large (MW level), such as wind turbines in the United States, Denmark, and Germany. The diameter of the wind rotor is 60m to 100m, and the power generation of the wind turbine is 2MW-3MW. Since t...
