The installation process is also constantly innovation, including the installation of steam turbine unit for shaft center link, steam turbine unit is one of the most important link in the installation, it process quality is good or bad will directly affect the safety and reliability of units and the economy. Based on the introduction of Siemens technology of 1000 MW ultra-supercritical turbine shaft find center as an example, analyzed and discussed thoroughly, in order to improve the quality of installation, realize the safe and reliable operation of the unit. Keywords: 1000 MW ultra supercritical steam turbine unit; Axis installation; Find center process 引进西门子技术的1000MW超超临界汽轮发电机组，汽轮机机型号为（N1000-26.25/600/600）型。机组采用HMN型积木块组合串联布置。包括一个单流圆筒型H30高压缸，一个双流M30中压缸，两个N30双流低压缸。汽轮机四根转子分别由五只径向轴承来支承，除高压转子由两个径向轴承支承外，其余三根转子，即中压转子和两根低压转子均只有一只径向轴承支承。五个轴承均为椭圆瓦，分别位
