Research on simulation of soft starting of high-voltage asynchronous motor based on on-off transformer

2012 
The working principle of high-voltage asynchronous motor's soft starter based on the on-off transformer is analyzed,and dynamic mathematic model of soft starting simulation is set up.The various kinds work state of soft starting is fully analyzed and the symmetrical component method for solve the input voltage of state equation is put forward.The control method of soft starting is proposed and simulation is carried out through a example.The simulation results are close to the experiment results,which verifies the correctness and validity of the simulation method.
