| 摘 要： | 研究对象为PG9171E型燃气轮机为顶循环的联合循环机组，构建了燃气-蒸汽联合循环系统变工况模型.通过改变环境温度及相应边界条件，分析了环境温度对联合循环机组全工况性能及调峰能力的影响情况.结果表明:以性能保证工况作为基准工况，降低大气温度，以冬季工况为代表，其全工况性能优于基准工况，效率比基准工况提高幅度为1.69%~3.75%，其出功增加幅度为11.48%~11.57%；提高大气温度，以夏季工况为代表，其全工况性能劣于基准工况，效率降低幅度为2.56%~5.08%，其出功降低幅度为10.44%~10.58%；对于机组的调峰能力，随着环境温度的升高，机组的调峰能力在降低，-20℃时联合循环机组最大、最小发电负荷分别为47.63，242.62 MW；40℃时最大、最小发电负荷分别为39.14，172.12 MW，全年温度范围内调峰幅度为132~194 MW.

| Abstract: | Taking a cycle combined with PG9171E gas turbine as the benchmark unit, a gas-steam combined cycle off-design model was established. By changing the ambient temperature and the corresponding boundary conditions, the design/off-design performance and peak load regulation of the combined cycle was analyzed. The results show that, basing the performance guarantee condition as the benchmark condition, with lower temperature as winter condition, the unit exhibits a better off-design performance, with the efficiency increment of 1.69%~3.75%, and its net power output will increase by 11.48%~11.57%. On the contrary, with higher temperature as summer condition, the unit shows lower off-design performance with the efficiency decrement of 2.56%~5.08%, and its net power output will decrease by 10.44%~10.58%. For the peaking load capacity of the unit, with higher temperature the capacity is less and the maximum and minimum generating loads is 47.63 MW and 242.62 MW at -20℃,at 40℃ is 39.14 MW and 172.12 MW respectively; and the peak load in the whole year temperature range is 132~194 MW. |
