Tower lifting resistance vertical axis multilayer wind power storage power generation device

Abstract

The invention discloses a tower lifting resistance vertical axis multilayer wind power storage power generation device. The device comprises an H-shaped vertical axis fan 6, a gear box 7, a clutch 8, an air compressor 9, a tower body 10 and a compressed air energy storage closed air chamber 12; the five items 6, 7, 8, 9 and 12 can perform multilayer combination according to design demands; high-pressure air currents are input in a constant-pressure air closed air chamber 17 through a high-pressure input pipe and a high-pressure airflow input automatic control valve after pressure increment and energy storage; and the stable and controllable high-pressure air currents are sprayed to a turbine generator set 23 through a high-pressure airflow nozzle 22 and a controllable airflow output automatic control valve 21 for acting power generation. Safety valves and pressure meters are respectively mounted on the compressed air energy storage closed air chamber 12 and the constant-pressure air closed air chamber 17. The turbine generator set sends a top-quality power supply with stable voltage, stable current and stable frequency. The top-quality power supply can be distributed to a synchronization circuit 26 and a direct user circuit 27 through a power distribution disc 25.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a tower-type lift-drag type vertical-axis multi-layer wind energy storage power generation device. Background technique [0002] The currently known wind power generation system is a device that converts wind power into electrical energy by directly connecting the wind blades to the generator set or by driving the generator to rotate to generate electricity through a transmission system. Usually includes wind rotor, transmission system, yaw system, hydraulic system, braking system, generator, control and safety system, nacelle, tower and foundation. This kind of power generation system has complex process, high technical difficulty, high equipment manufacturing cost and high operating cost. The most fundamental problem is low wind energy density, low wind energy conversion efficiency, and the randomness of wind speed makes wind power intermittent, unstable and uncon...

Problems solved by technology

This kind of power generation system has complex process, high technical difficulty, high equipment manufacturing cost and high operating cost. The most fundamental problem is low wind energy density, low wind energy conversion efficiency, and the randomness of wind speed makes wind power intermittent, unstable and uncontrollable. These are the key issues restricting the large-scale application of wind power

[0003] Chinese invention patent application specification CN105156158A discloses a wind power generation device, which includes a fan, an air compressor, a high-pressure gas storage tank, and a turbogenerator set. According to the description, it is only a wind power generation device capable of producing alternating current. According to the manual, there is no energy storage function. When the air storage tank is overpressured by the wind, the safety valve releases pressure and discards energy. The wind speed does not meet the design requirements and the steam turbine cannot run stably or start when there is no wind.
