Abstract: In order to meet the discharge requirements, starting device of slip regulator of the 300MVA pulse 
generator set on HL-2M tokamak is studied. Based on the electrical characteristics of the wound asynchronous 
motor, the set is started by means of an external liquid resistor to the rotor of motor. The size of the liquid 
resistance and the starting time were calculated when different currents were used for starting, and the flow rate 
and capacity of the resistive lye and the flow rate of the cooling water were calculated. The control strategy was 
proposed according to the constant current starting method. The size of the liquid resistance of the slip regulator, 
the volume of the lye tank, the flow rates of the lye and the cooling water were determined. The three-phase liquid 
resistance was measured and adjusted to ensure that the motor current fluctuated very little when the unit was 
started. The commissioning results show that the designed slip adjustment device is feasible and can provide a 
reference for the design of slip adjustment device for high power high voltage motors.
