The invention provides a double-direct-drive type double-wind-wheel wind generating set which comprises a first generator, a second generator, a tower drum, a front main shaft, a rear main shaft, a cabin, a front wind wheel and a rear wind wheel, the front wind wheel is connected with the first generator through the front main shaft, and the rear wind wheel is connected with the second generator through the rear main shaft. Therefore, according to the double-direct-drive type double-wind-wheel wind generating set, the front direct-drive type wind wheel and the rear direct-drive type wind wheel are installed on the fan tower barrel in series, the front wind wheel is connected with the first generator rotor through the front main shaft, the rear wind wheel is connected with the second generator rotor through the rear main shaft, and a front gearbox and a rear gearbox are omitted; and the maintenance difficulty and cost of the unit are reduced. Meanwhile, the two completely independent generators are utilized to realize complete decoupling of electrical control of the front and rear wind wheel power generation systems, so that the performance of cooperative control of rotating speed and torque of the front and rear wind wheels is improved, and the power generation efficiency of the unit is further improved.
Description
technical field [0001] The invention relates to the technical field of power generation, in particular to a double direct drive type double wind turbine wind power generator set. Background technique [0002] With the development of wind power generation technology, the diameter of the rotor of the existing wind turbines is getting larger and larger, and the capacity of the unit is also getting larger and larger. As a result, the development difficulty of wind power generation technology is also greatly increased. In particular, the larger capacity The development of wind turbines is more restricted. [0003] However, in the related art, there is no perfect design of the dual-turbine wind turbine to break through the above limitation. Therefore, how to greatly increase the capacity of the double-wind turbine wind turbine and improve the power generation efficiency of the double-wind turbine has become an urgent problem to be solved. SUMMARY OF THE INVENTION [0004] The ...
