Problems solved by technology
When the ambient temperature rises, the air density decreases, resulting in a decrease in the mass flow through the compressor and gas turbine, resulting in a decrease in the output of the gas turbine
The increase in ambient temperature will also reduce the compression ratio of the compressor and increase the power consumption, resulting in a further decrease in the output of the gas turbine
[0003] When the gas turbine unit is at full load, as the ambient temperature rises, the output and thermal efficiency of the gas turbine will decrease

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 [0001] The invention relates to a combustion engine air intake cooling control system. Background technique [0002] The gas turbine is a constant-capacity power machine, and its performance is closely related to the ambient temperature. When the ambient temperature rises, the air density decreases, resulting in a decrease in the mass flow through the compressor and gas turbine, resulting in a decrease in the output of the gas turbine. The increase in ambient temperature will also reduce the compression ratio of the compressor and increase the power consumption, resulting in a further decrease in the output of the gas turbine. [0003] When the gas turbine unit is at full load, as the ambient temperature rises, the output and thermal efficiency of the gas turbine will decrease. Therefore, configuring the air intake cooling system in non-winter periods can increase the output of gas turbines or combined cycle units and enhance the peak-shaving performance of...
