The Study of Full-Voltage Starting Method of High-Power Asynchronous Motors with Dynamic Reactive Power Compensation

For all sorts of problems in the procedure of high-power induction motor´s starting, as well as the drawbacks of traditional starting method. This paper proposed the full-voltage starting method of high-power induction motor with dynamic reactive power compensation, introduced its principle, and studied the control strategy of full-voltage starting with dynamic var compensation emphatically, established the simulation model using the Matlab/Simulink simulation software and carries out the simulation to examples, simulation results had 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, it has a better starting performance than the traditional starting methods..
