Offshore wind energy storing and conveying system for pneumatic power generation

Abstract

The invention discloses an offshore wind energy storing and conveying system for wind power generation. A plurality of offshore wind driven generators, a gas storage system and a pneumatic generator are included, the offshore wind energy storing and conveying system is a system through which offshore wind energy is converted into compressed air potential energy for storage and long-distance transportation, and the offshore wind energy is converted into kinetic energy for a fan blade shaft to drive an air compressor to work. According to the air transmission rate, reasonable water depth is selected to arrange a flexible air bag, constant-pressure compressed air with the same pressure as the water pressure is stored in the flexible air bag, sufficient compressed air is pressed to the pneumatic generator above the sea level through the constant water pressure, and the transmission rate and the air supply time can be accurately controlled, so that stable electric power output is obtained; and offshore wind energy is utilized to the maximum extent, the cost of offshore power generation and electric energy transmission is saved, and usage of underwater cables is replaced. An underwater flexible bag body stores energy online, the problem about wind power generation electric energy storage is solved, compressed gas is stably and continuously supplied, stable power output is guaranteed, and grid connection is easy.

Description

technical field [0001] The invention relates to the technical field of wind energy transmission for wind power generation, in particular to an offshore wind energy storage and delivery system for aerodynamic power generation. Background technique [0002] Wind power generation is to convert the kinetic energy of the wind into mechanical kinetic energy, and then convert the mechanical kinetic energy into electrical kinetic energy. The wind power generation unit is roughly divided into three parts: the wind wheel, the generator system and the iron tower. The wind power generation system is composed of a wind power generator, a charger and a digital inverter. The function of the generator is to convert the constant speed obtained by the wind wheel Through the speed increase, it is transmitted to the generating mechanism for uniform operation, and the mechanical energy is converted into electrical energy. [0003] In offshore wind power generation, the components in the nacelle...
