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.
