s:With the study of soft starting system for differential gear train on large belt conveyor from the speed governing control point of view,it can be found that the controlling speed of the system is decided not only by the parameters of differential gear train but also by the power ratio and the ratio of pole num-bers of both motors.

This article introduces the concept of technology of virtual prototype and analyses the characterizations and the advantages in designing controlled soft start system with virtual prototype.

This paper analyzes on the problems existing in the start of the large-scale belt-conveyer,and puts forward a method for solving this problem,which is adopting CST controllable soft start system.

The architecture and operation principle of SINAMICS GL150 soft static-starting converter is mainly discussed in this thesis.
