摘　　要：为了进一步推动1 200 MW等级机组发展,从主机容量、主机参数、主机技术条件、主要系统配置和热经济性指标等方面对某沿海电厂2×1 200 MW超超临界机组进行了可行性分析,结果表明:1 200 MW等级超超临界机组是可行的、可靠的,已具备推广应用条件。与1 000 MW等级机组相比,1 200 MW等级超超临界机组单位占地面积更小,年供电量更大,经济效益更高。该1 200 MW等级超超临界机组热效率为46.20%,发电标煤耗为266.25 g/(kW·h),供电标煤耗为277.34 g/(kW·h),达国内先进水平。The feasibility study of a 2 × 1 200 MW ultra-supercritical unit in a power plant in coastal area was completed to further promote the development of 1 200 MW units, from the aspects of the main equipment capacity, main equipment parameters, specifications for main equipment, main system configuration and thermal economy, and so on. The results show that, 1 200 MW ultra-supercritical unit is feasible and reliable, which can be applied in our country. Compared with 1 000 MW units, 1 200 MW ultra-supercritical unit has a lesser unit occupation area, a larger annual power supply, and a better economic profit. The 1 200 MW ultra-supercritical unit has a 46. 20% thermal efficiency, a 266. 25 g/（ kW · h） gross coal consumption rate and a 277.34 g/（ kW · h） net coal consumption rate, and is advanced in China. The 1 200 MW ultra- supercritical unit is the latest trends of bigger capacity units.
