Title:
GAS TURBINE SYSTEM COUPLED WITH ENERGY STORAGE SYSTEM AND HAVING ADJUSTABLE COMPRESSION FLOW, AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/197458
Kind Code:
A1
Abstract:
A gas turbine system coupled with an energy storage system and having an adjustable compression flow, and a control method. The system comprises a high-pressure gas storage system, a heat exchange system, a comprehensive gas supply system and a gas turbine system body, wherein a full-angle inlet adjustable guide vane (14) and a gas compressor outlet adjustment baffle (15) are respectively arranged at an inlet and an outlet of a gas compressor chamber in the gas turbine system body, and the gas compressor outlet adjustment baffle (15) is connected to a gas compressor outlet adjustment baffle control valve (16); a gas compressor anti-surge valve (17) is arranged in the gas turbine system body; a gas storage tank (4), a low-temperature gas supply section (11), a medium-temperature gas supply section (13) and a high-temperature gas supply section (12) are arranged in the comprehensive gas supply system; and the heat exchange system absorbs heat of high-temperature and high-pressure air and stores the heat, and then releases the heat into the high-pressure air, and the high-pressure air is then conveyed to the gas turbine system body through an outlet of the comprehensive gas supply system. A load reduction operation and an even zero output operation of a gas compressor of the gas turbine are realized, the power consumption of the gas compressor is effectively reduced, and externally stored high-pressure gas is fed into a combustion chamber for consumption during a peak period of power consumption, so that the comprehensive utilization of peak regulation-energy storage-power generation is realized.
