Description: As the main load in the power network, the control of asynchronous motor is always an important problem.In the starting process of asynchronous motor, if directly started, it will cause a large current, will affect the stability and safety of the power grid;The starting torque and operating efficiency are also low.In order to improve the above problems, the use of soft starter to start the asynchronous motor can realize the non-pole adjustment of starting voltage, thus limiting the starting current, which can improve the motor performance to a certain extent.In this paper, the current closed-loop is adopted as the control mode, and MATLAB is used to build the model and simulate the soft starting system of asynchronous motor, and then the advantages of soft starting are illustrated.
