Based on investigation on basis of physical process of the motor running under different negative sequence, calculation simulation model for steam turbine generator field was established on a 1266 MW half speed steam turbine generator for nuclear power generation, and according to time-step finite element electromagnetic theory, the 2-d finite element mathematical model is established. According to the numerical method, the magnetic field distributions inside the motor at the rated running state, with 1%IN, 2%IN, 3%IN, 4%IN and 5%IN negative sequence current were calculated. Based on the comparison and analysis of the magnetic fields inside the motor, influence of the negative sequence component proportion on the magnetic field distribution was investigated. The results could provide the reference for the design of operation and protection scheme of the generator.
