摘　　要：以某1 000 MW汽轮机组为研究对象,采用汽轮机组定功率变工况计算方法,对汽轮机排汽压力在THA、70%THA滑压、50%THA滑压、40%THA滑压工况进行敏度分析,可求得各种工况下汽轮机组排汽压力对汽轮机热耗、发电煤耗和供电煤耗的影响,从而指导同类汽轮机组进行节能诊断和经济运行。Based on the constant power variable condition calculation method, the energy-consumption sensitivity of the exhaust steam pressure is analyzed for 1 000 MW steam turbine on the conditions of THA, 70% THA sliding pressure, 50% THA sliding pressure and 40% THA sliding pressure. The effect of the exhaust steam pressure on energy- consumption performance is derived with the unit heat rate, coal consumption rate and power coal consumption rate. The results can be referred to for the energy-saving diagnosis and operation optimization of similar power units.
