Skidding Research of a Traction Asynchronous Electric Drive in the Electric Locomotive on a Dynamic Model

Abstract

The relevance of the work lies in the possibility of using a computer model in the development and research in the FC-AD (Frequency Converter – Asynchronous Drive) system for the electric drive of an electric locomotive. On the developed dynamic computer model of an asynchronous motor for a shunting locomotive, studies of gap selection in the coupling and skidding have been carried out. The purpose of the article is to conduct research on transient processes of the gap selection and skidding on a dynamic computer model of a traction asynchronous electric drive based on the FC-AD system with various control systems. The developed computer model is based on specific parameters of the traction asynchronous electric drive, allows calculating transient processes in the FC-AD system, taking into account skidding and the gap selection. The article has structural diagrams of mathematical models that take into account the operation of the traction electric drive, taking into account various control and skidding systems. On the basis of a dynamic computer model, computer models have been developed for studying transient processes in various control systems when choosing the gaps in the coupling and skidding.
