摘要
Abstract
Large turbo-generators may suffer electromagnetic forces from the winding ends. When the frequency of the electromagnetic force or twice of operation frequency is close to the inherent frequency of the stator’s end, large vibration will occur which can cause potential risk. So, study on the end winding vibration of the large turbo-generator is important. In this pa-per, a 3D finite element model of the simplified end winding was established. The modal analysis was done and the first two or-der vibration modes were obtained. Then, the modals of the end winding were tested, and the result was compared with that of the simulation. Their difference was found to be allowable. The correctness of this simulation was verified. This work may pro-vide a basis for design and safe operation of turbo-generators.关键词
