Abstract
The present disclosure relates to the field of energy storage, and provides a rapid-response energy storage system and a using method thereof. The system comprises an air storage chamber, a compressor unit, an expander unit, a compressor unit lubrication station, an expander unit lubrication station, a compressor unit oil cooler, an expander unit oil cooler, a compressor unit oil pump and an expander unit oil pump; an outlet of the compressor unit communicates with an inlet of the air storage chamber through a heating pipe inside the expander unit lubrication station, and an outlet of the air storage chamber communicates with a heating pipe inside the compressor unit lubrication station sequentially through a regulating valve and the expander unit; the compressor unit lubrication station, the compressor unit oil pump, an oil way inside the compressor unit and the high-temperature side of the compressor unit oil cooler are sequentially connected end to end to form a first oil circulation loop; and the expander unit lubrication station, the expander unit oil pump, an oil way inside the expander unit and the high-temperature side of the expander unit oil cooler are sequentially connected end to end to form a second oil circulation loop. According to the present disclosure, rapid responses can be achieved and the lubricating oil can be heated without the consumption of external thermal energy.
