结合印度电力监管委员会（central electricity authority，CEA）的2010版电站设计导则，依托印度某2×660 MW超临界电站工程，对国内三大动力厂（上海汽轮机有限公司、东方汽轮机厂及哈尔滨汽轮机厂）的汽轮机主要技术特点进行分析总结，通过对机组优选的凝汽器背压进行技术经济比较，最后得出对于印度工程，600 MW级机组均为基本负荷机组，机组设计背压定义为9.5 kPa时经济性优于10.13 kPa。研究结论供后续印方业主设计咨询项目参考和借鉴。

Based on a 2×660 MW supercritical power plant in India, this paper analyzed the main technical features of three turbine manufactory in china (Shanghai steam turbine Co., Ltd., Dong Fang steam turbine works and Harbin steam turbine factory), combined with the Power Plant Design Guidelines (2010) formulated by India Central Electricity Authority Regulations. Through the technical & economical comparison of condense back pressure, the results show that the 600 MW class unit in India is base load in the grid, and the back pressure of condenser design as 9.5 kPa is better than 10.13 kPa. The research results can possesses reference meaning for the future design consultation project in India.
