This paper proposes a two-dimensional finite element mathematical model taking the mf-15 simulation generator in the dynamic model laboratory as the research object. The electromagnetic performance of the motor under no-load and rated load was analyzed to verify the correctness of the model. By using the method of field-circuit coupling combined with simulation analysis, the limit value of the generator’s phase-in depth is determined, and the variation law of the electric and magnetic field distribution with the depth of the generator’s established Leading phase operation is analyzed, as well as the influence of the phase-in operation on the system’s operation stability. The results obtained provide a reference for the phase-in operation analysis of large generators. View Full-Text
