汽轮发电机基座静变位分析和探讨

Analysis and approach on static deformation ofturbogenerator foundation

按照上海电气1 000 MW西门子机型汽机基础设计标准STIM,对某工程汽机基础的静变位进行了分析计算,并对常规基础和弹簧基础的计算结果进行了对比分析,研究了设备刚度对于静变位的影响.分析结果对今后类似机型的基础设计具有一定的参考价值.

Firstly according to the Shanghai Electric 1 000MW Siemens models of turbogenerator foundation design standard STIM,the static deformation of turbogenerator foundation of a certain project is calculated and analyzed.And then the calculation results of traditional and the spring-type foundations are analyzed comparatively.Meanwhile,the influence of equipment stiffness on the static deformation of turbogenerator foundation is analyzed emphatically.The analytical results have a certain reference value for design of similar type turbogenerator foundations in the future.
