Simulink Model of High-Speed Train Pantograph-Catenary Offline Arc

Based on the classic arc theory, starting from the formation mechanism of high-speed train bownet arc, the modeling method in Simulink simulation environment is analyzed. The model consists of offline motion trajectory simulator, offline arc simulator, external traction network equivalent circuit, train, etc. The external parameters of highs-peed trains, such as train running speed, pantograph mass, pantograph lifting force, and contact line density, are used as variables that affect arc characteristics, which can reflect the dynamic changes of offline arcs during high-speed train operation. This article provides a basis for the interference source modeling of rail transit electromagnetic compatibility problems caused by bownet offline. After modeling the electrical equipment of the train, using this model can further study the electromagnetic compatibility of rail transit caused by bownet offline under various working conditions. The problem can, to a certain extent, replace field tests with long cycles and complicated steps.
