Description

technical field [0001] The invention relates to the technical field of power generation, in particular to a power generation system and a control method thereof. Background technique [0002] The efficiency of the gas-steam combined cycle power generation system is related to the efficiency of the gas cycle (i.e. the efficiency of the gas turbine) and the efficiency of the steam cycle (i.e. the efficiency of the steam turbine). Improving the efficiency of the gas cycle or the efficiency of the steam cycle can improve the efficiency of the gas-steam combined cycle power generation system . Among them, the improvement of steam cycle efficiency is mainly achieved by increasing the inlet steam parameters of the steam turbine. In the prior art, the steam turbine is usually a steam turbine, and since the steam turbine has high requirements on the quality and parameters of the steam, it also has high requirements on the parameters of the inlet flue gas of the waste heat boiler. I...
