Abstract

The invention discloses a wind generating set with an energy-storage flywheel. The wind generating set comprises a hub, a main shaft, a main shaft bearing support, a main shaft gear, a flywheel transmission gear shaft, a first clutch, a second clutch, a first transmission shaft, a second transmission shaft, a third transmission shaft, a hydraulic torque converter, a first transmission gear, a second transmission gear, the flywheel, a gearbox, an electric generator and a machine cabin, wherein the flywheel transmission gear is meshed with the main shaft gear, the first clutch and the second clutch which are arranged on two sides of the flywheel transmission gear respectively are connected with the first transmission shaft and the second transmission shaft respectively, the other end of the second transmission shaft is connected with the third transmission shaft through the hydraulic torque converter, the first transmission shaft and the second transmission shaft are sleeved with the first transmission gear and the second transmission gear respectively in a fixed mode, and the first transmission gear and the second transmission gear are meshed with internal gears of the flywheel. The wind generating set with the energy-storage flywheel achieves the purpose that wind energy converted by the electric generator can be stored when the wind speed in a wind field is too high.

Description

technical field [0001] The present application relates to the field of wind power generators, in particular to a wind power generator with an energy storage flywheel. Background technique [0002] As a clean and renewable energy, wind energy has huge reserves. The available global wind energy is about 2 million megawatts, which is almost 10 times that of the global hydropower generation that can be developed and utilized. The world burns coal every year. The energy obtained is only one-third of the energy provided by the wind in a year. Therefore, wind power generation has been paid more and more attention by countries all over the world. [0003] The currently constructed wind power stations are composed of a large number of wind power generators, each of which converts the kinetic energy of the wind into mechanical energy through a wind wheel, and then converts the mechanical energy into electrical energy through a generator and outputs it to the power grid. [0004] How...
