This paper analyzes and researches start process of 6-phase AC pulse generator set, equivalent math model for starting process of the generator set is given, modeling of con- stant stator current for three-phase wound-rotor induction motor, which rotor is connected with liquid resistance in series, is implemented. Dynamic characteristic curve for starting process of the generator set is achieved based on the simulation for starting process of a 6-phase AC pulse generator set, the obtained result provides theoretical references for design of the control section and running mode of the generator set.
