Compressed air energy storage power generating system

Abstract

A compressed air energy storage power generating system comprises an electromotor, an air compressor, a high-pressure air storage tank, a low-pressure steam turbine and a power generator, wherein the electromotor drives the air compressor, the low-pressure steam turbine drives the power generator, and air compressed by the air compressor drives the low-pressure steam turbine. The compressed air energy storage power generating system is high in efficiency, long in service life, convenient in storage and use, high in storage capacity, low in investment cost, is energy-saving, emission-reduction, low-carbon and environment-friendly by utilizing compressed air to generate power, breaks the scope of all power machines, is a perfect combination of the fluid mechanics, the air pressure mechanics, the lever mechanics and the potential energy mechanics, and is capable of circulating self energy supply and realizing multiple work application, so that mechanical efficiency of the compressed air energy storage power generating system is improved greatly and more energy can be saved. Besides, heat insulation and dissipation are out of consideration since ultrahigh pressure steam driving is omitted. The compressed air energy storage power generating system is simple in structure, low in cost, convenient in maintenance and durable, and can be applied to power dragging and power generation widely.

Description

technical field [0001] The invention relates to a power generation system, in particular to a compressed air energy storage power generation system. Background technique [0002] The development and utilization of earth's energy is still a major issue in today's world. While continuously developing new energy, how to use existing energy more effectively, including the development of energy saving and energy storage technology, is more concerned by the world, especially the storage The development of energy technology has become an urgent project, because with the rapid development of society, the current power consumption is extremely unbalanced, and the ratio of nighttime load to daytime load is almost 1:100, while thermal power that bears the base load In particular, it is difficult for nuclear power to shut down and extinguish the furnace during the nighttime low load period. Even during the daytime peak load period, the number of intermediate units used for peak regulati...
