A Four Axle Shunting Electric Locomotive Control System Based on Inverter-Induction Motor Technology with Account of Slipping

The relevance of the paper lies in the possibility of using a computer model in the development and study in the processes in an electric locomotive traction electric drive asynchronous motors operation for various operating modes. The purpose of the paper is a four-axle locomotive mechanical features mathematical description, taking into account the slipping process, the development of a control system for the traction electric drive for an electric locomotive using the FC-AM electric drive configuration in condition of the slipping process and testing its performance on a computer model. For the four-axle electric locomotive derived equations and analyzed the conditions for the occurrence of slipping process, taking into account the pressure on 4 wheel sets with unloading and overload from traction, developed a new block diagram of the control system for the traction electric drive of an electric locomotive according to the FC-AM system configuration, its performance is tested on a computer model. The developed new control system for the traction electric drive of a four-axle electric locomotive makes it possible to use the engines to operate more efficiently, without bringing them to uncontrolled slipping and reducing the power consumption of the FC-AM system.
