燃气-蒸汽联合循环机组的运行性能容易受到环境温度的影响，使得机组在电力负荷需求高峰期面临出力不足的问题.为了解决这一问题，基于EBSILON软件，对耦合溴化锂制冷机组的SGT5-4000F型燃气-蒸汽联合循环进行仿真建模，并将冷却装置加装到压气机入口处，模拟分析进气温度对联合循环输出功率和循环效率的影响规律.研究表明：通过改变压气机进气温度可知降低进气温度可使得联合循环发电功率提高4.73%-6.10%.在温度较高的夏季工况，在燃气轮机的压气机进气口处加装进气冷却装置可以提高机组的性能，并且温度越高，联合循环输出功率提高的效果更好.
Abstract：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.
