Recently, the mechanical group of the product development department of the technical department has passed the review, adopted the research and verification of the stator winding end modality with the glue injection structure, and formed a modal measurement method and evaluation standard for the end of the generator stator winding windings. , so that our factory is in the domestic leading position in this technology field. As one of the five core technologies of our plant generators, modal analysis technology is an important part of our 3G technology. The stator end modes directly affect the safe operation of the unit. In the design and manufacture of the turbine generator, the modal characteristics of the stator end must be mastered to optimize the end structure in order to ensure safe operation of the end windings. However, due to the complex structure and various materials of the stator stator end, the boundary conditions of the structural model are difficult to determine, the thermodynamic environment of the operating conditions is complex, and its dynamic characteristics change with the change of the ambient temperature. End-mode characteristics of the system are analyzed systematically. This project is based on a 1200 MW turbine generator product and conducts in-depth study on optimization of material parameters and determination of structural boundary conditions in the calculation of stator end modes, starting from the experimental and computational aspects to determine the material parameters and boundaries of each component. Under the conditions, the modal characteristics of the integrated overall structure are obtained, the method and flow of the end mode analysis of the glue filling structure are perfected, and the gap of the thermal mode analysis of the stator stator winding end of the plant is filled and enriched. Our factory 3G technology shelves further consolidate our factory's leading position in the field of stator winding hot end mode technology.
