The invention discloses an inlet air cooling control system for a gas turbine. The system comprises heat exchangers, hot water circulating pumps, absorption water cooling units and air coolers, wherein the heat exchangers, the hot water circulating pumps and the absorption water cooling units are connected one another through hot water supply pipes; the absorption water cooling units and the air coolers are connected through freeze water supply pipes; the heat exchangers and the absorption water cooling units are further connected through hot water return pipes; and the absorption water cooling units and the coolers are further connected through freeze water return pipes. The system further comprises a control cabinet which is connected to the hot water supply pipes, the hot water return pipes, the freeze water supply pipes and the freeze water return pipes. The inlet air cooling control system for the gas turbine disclosed by the invention is high in safety: once problems or faults happen at a place, the control cabinet sends out a command to cut off the system so as to ensure the integral safety; automatic control is realized through the control cabinet, and to-be-monitored parameters are centralized to a control room, so that the user knows the working state of each part of the system anytime and sends out the control command.
Description
Technical field
The present invention relates to a kind of combustion engine inlet gas cooling control system.
Background technology
Gas turbine is constant volume type dynamic power machine, and its performance is closely related with ambient temperature.When ambient temperature rises, empty
Air tightness reduces, thus causes the mass flow flowing through compressor and gas turbine to reduce, and causes the output drop of gas turbine.
Ambient temperature raises and the compression ratio of compressor also can be made to reduce, and wasted work amount increases, thus causes exerting oneself further of gas turbine
Decline.
When gas turbine unit is in full load condition, along with the rising of ambient temperature, exerting oneself and heat of gas turbine
Efficiency all will decline.Therefore, at period configuration charge air-cooling system in non-winter, combustion engine or Combined Cycle Unit can be increased
Exert oneself, strengthen peak load regulation performance.
