The invention discloses a gas-steam combined cycle power generation system and method coupled with geothermal energy, comprising a compressor, a combustion chamber, a gas turbine, a waste heat boiler, a geothermal well, a heat exchanger, a recharge well and a steam turbine; Air, the other end is connected to the combustion chamber; the combustion chamber is fed with gas, the outlet of the combustion chamber is connected to the inlet of the gas turbine, and the gas turbine is equipped with a first generator; the outlet of the gas turbine is connected to the waste heat boiler; the wellhead of the geothermal well is connected to the first generator through the heat exchanger. Inlet, the first outlet of the heat exchanger is connected to the recharge well; the tap water pipe is connected to the second inlet of the heat exchanger, and the second outlet of the heat exchanger is connected to the waste heat boiler; the high temperature steam outlet of the waste heat boiler is connected to the steam turbine through the steam pipe , the steam turbine is equipped with a second generator. It can provide a way to effectively use geothermal resources in non-heating areas, which can effectively expand the application scope of clean energy; at the same time, it can make full use of geothermal resources, reduce the power consumption of gas turbine power generation systems, and save operating costs for power companies. . |
