Wind driven generator system based on flywheel energy storage speed adjustment

Abstract

The invention discloses a wind driven generator system based on a fly wheel energy storage speed adjustment. The wind driven generator system based on the fly wheel energy storage speed adjustment comprises fan blades, a wind wheel axis, a fly wheel, a main shaft and a generator. The fan blades are fixed at one end of the wind wheel axis, a round hole is formed in the end face of the other end of the wind wheel axis, and ratchets are arranged on the circumferential inner wall of the round hole. A ratchet wheel is arranged on the fly wheel, penetrates through the round hole, and is provided with pawls which are matched with the ratchets. The fly wheel, the main shaft and the generator are fixedly and coaxially connected in sequence. When wind force is strong, the fly wheel is utilized for storing residual wind power. When the wind force is weak, the wind energy stored by the fly wheel is released to drive the generator, at the same time, the speed of the generator is stabilized in a certain range through the fly wheel, and the fluctuation of output electric energy of the generator caused by wind force fluctuation is eradicated so as to achieve the purpose of improving electric energy quality. The wind driven generator system is directly installed on a wind generating set by utilizing of a mechanical method, the process belongs to the conversion between mechanical energy, and conversion times are reduced and loss is reduced.

Description

technical field [0001] The invention belongs to the field of new energy power generation and access technology, and relates to wind power generation technology in smart grids, new energy development technology, and wind power grid connection technology, in particular to a wind power generator system based on flywheel energy storage and speed regulation. Background technique [0002] The proportion of wind power generation in the power system is increasing day by day. Due to the random and intermittent nature of wind power, problems such as voltage fluctuations, frequency offsets, and harmonic pollution caused by wind power generation to the power system have become increasingly prominent. In addition, the regions rich in wind resources in my country are mostly distributed in the central and western regions where the power grid is relatively weak. The grid connection of a large number of wind turbines has brought great challenges to the normal operation of the existing power s...
