摘　　要：随着我国水轮发电机组制造与安装技术的不断进步,水电建设行业也在积极改进和完善制造、安装环节中存在的不足,从而使机电设备的安装标准和要求更加严格,尤其是大型水电站,其安装标准已经远超国家规范和设计要求。部分大型水电站受安装间工位影响或为保证机组安装的高质量标准及安全稳定运行,其发电机定子在机坑内经过一系列的工序装配成整体并最终安装就位。在定子装配或安装过程中,由于定子部件的中心、高程等定位的方式不精准或不便于复核,极易造成定子中心的重复调整而降低施工效率、增加施工成本或增大机组的安装偏差,最终影响机组的安全稳定运行质量。本文阐述了在大型、超大型立式水轮发电机组定子机坑内组装时所采用的精准定位技术并进行了分析。With continuous improvement in technical level of hydraulic turbine manufacturing and installation in China,the hydropower construction industry is also actively improving insufficiency and deficiency during manufacturing and installation,thus making the installation standards and requirements for electromechanical equipment more stringent,especially for large hydropower stations where standards and specifications are far above national standards and design requirements.Some large hydropower stations are affected by the working positioning or to guarantee high quality standards of unit installation and safe and stable operation.The generator stators will be assembled into a whole in the pit through a series of processes and finally installed in place.During the assembly or installation process,because the center and elevation of the stator components are positioned inaccurately or inconveniently for review,it's prone to cause repeated adjustment of stator's center,lower construction efficiency,cost rising or increased deviation of units,ultimately affecting the safe and stable operation quality of the unit.This article mainly analyzes the precise positioning technology adopted during stators assembly in the pit in super-large vertical hydraulic turbine units.
