Compressed-air-storing electricity generating system and electricity generating method using the same

Abstract

Disclosed are a compressed air energy-storing electricity generating system and an electricity generating method using the same, in which air of a high pressure is injected into a tank laid under the ground using midnight electricity and surplus produced electricity, and the air of the high pressure in the tank is uniformly discharged so as to drive a generator during a time period when the consumption of electric power is high, thus efficiently managing energy.

Description

technical field [0001] The present application relates to a compressed air energy storage power generation system and a power generation method using the system, and more particularly, to a compressed air energy storage power generation system and a power generation method using the same, wherein nighttime power and excess produced Electricity, injecting high-pressure air into a tank placed underground, and uniformly discharging this high-pressure air in the tank during periods of high power consumption to drive a generator, thereby efficiently managing energy. Background technique [0002] Nighttime power is electricity used at night when power consumption is low, from 10:00 p.m. of one day to 8:00 a.m. Electricity is oversupplied and therefore cheaper. Therefore, various methods of using nighttime power have been proposed. Typical installations that use nighttime electricity include regenerative boilers that use nighttime electricity and regenerative water heaters that u...

Problems solved by technology

However, since the compressed air is continuously discharged to the outside, the pressure in the storage tank 30 gradually decreases, and the pressure of the discharged compressed air also gradually decreases, thereby reducing the driving efficiency of the turbine.
