Abstract

With the increase of the capacity of the generator, the electromagnetic force of the stator end winding of turbine-generator is increased, which can lead to the failure of the stator end winding. Based on this report, a finite element modeling method is proposed to solve the problem of complex structure modeling of turbine-generator stator end winding. The grid matching between electromagnetic and structural finite element model is realized. Meanwhile, the mechanical vibration performance of the turbine-generator stator end windings is analyzed by the method of the whole electromagnetic and local structure coupling simulation. The vibration performance of turbine-generator stator end winding under different reinforcement strategies are compared, and the preventive measures for the vibration fault of generator are explored.
