The invention provides a hybrid drive type double-wind-wheel wind generating set. The hybrid drive type double-wind-wheel wind generating set comprises a first generator, a second generator, a tower drum, a front main shaft, a rear main shaft, a cabin, a front wind wheel, a rear wind wheel and a gearbox, wherein the front wind wheel and the rear wind wheel are different in drive mode, and the gearbox is connected with the rear wind wheel and the second generator. Wherein 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 direct-drive and semi-direct-drive hybrid drive type double-wind-wheel wind generating set, the front wind wheel and the rear wind wheel which are different in drive mode are installed on the fan tower barrel in series, the gear box is arranged at the connecting position of the second generator and the rear wind wheel, and under the condition that the diameters of the wind wheels of the wind generating set are not increased, the power of the set is increased. Meanwhile, two completely independent generators are adopted, electrical control complete decoupling of front and rear wind wheel power generation systems can be achieved, the performance of rotation speed and torque cooperative control of front and rear wind wheels is improved, and then the power generation efficiency of the unit is improved.
Description
technical field [0001] The invention relates to the technical field of power generation, in particular to a hybrid-driven 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 present app...
