Abstract

The invention discloses a flywheel energy storage integrated wind power generation device and method. The flywheel energy storage integrated wind power generation device comprises a tower drum, a cabin is connected to the top of the tower drum through a yaw motor, a gear box and a generator are arranged in the cabin, an input shaft of the gear box is connected to blades located on the outer side of the cabin, and the input shaft and the blades are connected through a variable-pitch motor. An output shaft of the gear box is connected with the generator, the output end of the generator is connected to a converter through a fourth cable, and meanwhile, the output end of the generator is connected to a current mixer through a first cable; and the current mixer is connected to a flywheel energy storage device through a second cable, and meanwhile, the current mixer is correspondingly connected to the variable-pitch motor and the yaw motor through a third cable.

Description

technical field [0001] The invention belongs to the field of wind power generation, and in particular relates to a flywheel energy storage integrated wind power generation device and method. Background technique [0002] my country is a big energy consumer, but the pollution of fossil energy is becoming more and more serious, so it is imperative to develop clean and renewable energy. By the end of 2019, the installed capacity of renewable energy power generation accounted for 40%. With the further adjustment of the energy structure, the scale of new energy installed capacity and power generation will continue to increase further. However, wind turbines have gaps and fluctuations, and at some point it is necessary to increase energy storage as a backup and emergency safety guarantee power supply. [0003] At present, the wind energy storage technology solutions mainly include battery energy storage and capacitor energy storage. There are problems such as large volume, short...
