Wind power and low-pressure steam turbine hybrid energy-storage cycle power generation system

Abstract

A wind power and low-pressure steam turbine hybrid energy-storage cycle power generation system comprises a wind power storage portion and a low-pressure steam turbine power generation portion connected with the same. The wind power storage portion comprises a framework, a shaft mounted on the framework, an impeller mounted at one end of the shaft, a speed increasing box connected with the other end of the shaft and an air compressor connected with the speed increasing box. The low-pressure steam turbine power generation portion comprises a low-pressure steam turbine and a power generator connected with the low-pressure steam turbine. Compressed air stored in the wind power storage portion drives the low-pressure turbine power generation portion. The wind power and low-pressure steam turbine hybrid energy-storage cycle power generation system solves problems that a single wind driven power generator in convention wind power generation mode is low in power and efficiency, is unstable and intermittent, is easy to impact with the power grid when in grid connection and has affection on safety and stability in power supply and the like. Power generation efficiency is increased, and the problems about stability of grid connection and remote delivery in wind power generation are solved.

Description

technical field [0001] The invention relates to a power generation system, in particular to a wind power and low-pressure steam turbine complementary energy storage cycle power generation system. Background technique [0002] As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. With the development of the global economy, grid-connected wind power has developed rapidly. [0003] However, in the process of wind power generation, the blades generate rotational kinetic energy under the action of wind energy. After being accelerated by the gearbox, the generator is driven to generate electricity. The blades can also be used to directly drive the ultra-low-speed generator to generate electricity. Therefore, the grid-connected problem of wind turbines has not been well resolved [0004] In traditional wind power generation, a single wind turbine has low power, low efficiency, and instability. When connected to the gri...
