本文叙述了大型发电厂热力系统“冷端”参数的最优化的设计方法。用动态经济分析法对东北地区某发电厂拟安装2×600MW汽轮发电机组进行了优化计算,提出了2×2F869低压缸模型汽轮机和2×2F1044低压缸型汽轮机电站凝汽装置和冷却系统的最优化方案。进而提出2F1000低压缸型汽轮机电站凝汽装置和冷却系统的最优化方案,可为工程设计时选用。
This paper describes the design method for the optimization of the “cold side” parameters of the thermodynamic system in a large power plant. The dynamic economic analysis method was used to optimize the 2 × 600MW turbo-generator unit to be installed in a power plant in Northeast China. The 2 × 2F869 low-pressure cylinder model steam turbine and the 2 × 2F1044 low-pressure cylinder turbine power plant condensing unit and cooling system were proposed Optimization program. And then put forward 2F1000 low pressure turbine turbine condensing plant and cooling system optimization program can be used for engineering design.
