The invention discloses a high-power gas turbine generator set and an operation method thereof, which comprise a generator module, a gas turbine module, an air inlet filtering module, a fuel supply module and a starting module, wherein the main body of the gas turbine is composed of a compressor connected with the air inlet filtering module and used for compressing air, a combustion chamber connected with the compressor and used for mixing and combusting compressed air and fuel to generate high-temperature and high-pressure gas, and a turbine connected with the combustion chamber and used forconverting the energy of the high-temperature and high-pressure gas into mechanical energy, the turbine comprises a compressed air turbine coaxially connected with a rotor of the compressor and a power turbine coaxially connected with a rotor of the generator module through a coupler. The rotor of the compressor is driven by the compressed air turbine to rotate so that outside air enters the air inlet filtering module, and the rotor of the generator module is driven by the power turbine to rotate so as to convert mechanical energy into electric energy through the generator module.
Description
Technical field [0001] The invention relates to the technical field of gas turbine power generation, in particular, to a high-power gas turbine generator set and an operation method. Background technique [0002] At present, the domestic maximum power of light-duty gas turbines does not exceed 10MW. The shafting structure of a gas turbine generator set is mainly composed of gas turbine, high-speed coupling, reducer, low-speed coupling, generator and other equipment. The shafting structure is complex, the axis is difficult to align, the installation workload is large and the maintenance cost is very high. Summary of the invention [0003] The invention provides a high-power gas turbine generator set and an operation method to solve the technical problems of the existing gas turbine generator set shafting structure being difficult to align, resulting in large installation workload and very high maintenance cost. [0004] According to one aspect of the present invention, a high-power...
