For various problems in the procedure of high-power induction motor’s starting and disadvantages of traditional starting methods, this paper proposed a new type of full-voltage starting method of high-power induction motor—a full-voltage starting method with dynamic reactive power compensation, introduced its principle, studied the control strategy of full-voltage starting with dynamic var compensation emphatically, and established the simulation model for direct starting, soft starting and full-voltage starting with dynamic var compensation based on the Matlab/Simulink simulation software to do digital simulation and compared three methods. The simulation results indicated that the method proposed in this paper can make the high-power induction motor start fast and smoothly with both high-torque and low starting current, and it has a better starting performance than traditional starting methods and the advantage of not affecting power quality.
