摘　　要：对东方汽轮机厂、上海汽轮机有限公司和哈尔滨汽轮机有限公司3个厂家生产的不同类型1000 MW超超临界汽轮机从配汽方式、末级叶片特点、滑销系统特点、启动方式选择、润滑油系统布置、超速保护设计、甩负荷后转速控制等方面进行了分析对比,各厂家1000MW超超临界机组汽轮机在设计结构及控制上各有特点。通过对比,为1000 MW超超临界汽轮机的调试、运行和检修提供借鉴。Make comparision of the different type of 1000 MW Ultra Supercritical Steam Turbine（Units）, which are manufactured respectively by Dongfang Steam Turbine Plant, Shanghai Turbine Company Limited and Harbin Turbine Company Limited. Analyse the steam distribution mode, the characteristics of exhaust stage blade and sliding pin system, choose the starting mode, lubricating oil system, overspeed protection designing and the rotating speed after load dropping. These kinds of 1000 MW ultra supercritrcal steam turbine have different characteristics of structure and control. The comparision gives reference to the commissioning, operation and overhaul of the units.
