Technical Field

The invention relates to the technical field of air compression energy storage, in particular to a novel compressed air energy supply device.

Background

The compressed air energy storage is that the residual electric quantity is utilized when the load of the electric power system is in the valley, the air compressor is driven by the motor, and the air is pressed into the closed large-capacity underground space serving as the air storage chamber, i.e. the electric energy which can not be stored is converted into the air pressure potential energy of the compressed air which can be stored and is stored in the air storage chamber. When the generated energy of the system is insufficient, compressed air is mixed with oil or natural gas through the heat exchanger for combustion, and is introduced into the gas turbine to do work for power generation, so that the peak regulation requirement of the power system is met. The energy storage subsystem composed of the air compressor, the motor, the air storage chamber and the like stores low-price electric energy in a power station valley in the air storage chamber such as a rock cave and a waste mine through compressed air, and the motor generator is coupled with the air compressor through the coupler during energy storage and is decoupled with the gas turbine. When the power system is in peak load, compressed air is used for combustion to drive a gas turbine to generate electricity, the gas turbine, a combustion chamber, a heater and other electricity generating subsystems are used for generating electricity, and a motor generator is coupled with the gas turbine and is decoupled with a gas compressor during electricity generation.
