The gas-steam combined cycle unit's performance is vulnerable to changes in ambient temperature,resulting in a lack of output when the electric load is at its peak.To address this issue,EBSILON software is used to simulate the SGT5-4000F gas-steam combined cycle in conjunction with the lithium bromide refrigeration unit.The cooling device is placed in the pressurizer's inlet to assess the effect of the inlet temperature on the combined cycle output power and cycle efficiency.The research indicates that altering the compressor's inlet temperature can result in a 4.73%-6.10%increase in the total cycle power.By incorporating an inlet cooling device into the compressor inlet of the gas turbine during the summer working season,one can enhance the unit's performance.As the temperature rises,the collective cycle output power experiences a significant boost.
