The simulation of pantograph and catenary: a PDAE approach
Recently, the coupled dynamical simulation of pantograph and catenary in high speed trains has found much interest. The equations of motion form a partial diierential-algebraic equation (PDAE) that combines a partial diierential equation (PDE) for the catenary and a diierential-algebraic equation (DAE) for the pantograph. In the present paper we discuss the relation of this PDAE model to curren...
متن کاملPantograph-Catenary System Modeling Using MATLAB-Simulink Algorithms
Contacts between pantograph and catenary are the most critical parts in the transmission of electrical energy for modern high-speed trains. Contact wire oscillations change combined force between pantograph and catenary, and the contact may even get lost. Therefore special pantographs and catenaries have been developed and further constructive changes are under development. A design criterion i...
متن کاملHough transform and thermo-vision for monitoring pantograph–catenary system
The pantograph-overhead contact wire system is investigated by using an infrared camera. As the pantograph has a vertical motion because of the non-uniform elasticity of the catenary, in order to detect the temperature along the strip from a sequence of infrared images, a segment-tracking algorithm, based on the Hough transformation, has been employed. An analysis of the stored images could hel...
متن کاملEffect of Controller Parameters on Pantograph-Catenary System
Railway traction model is a complex mix of electrical and mechanical parameters. Pantograph acts as an active link between the catenary and electric drive used for driving the electric loco. It collects the current from the catenary and supplies it to loco transformer for feeding to the drive. Stable current collection is one of the foremost requirements for the efficient and reliable operation...
متن کاملModeling of Pantograph-Catenary dynamic stability
The purpose of this paper is to describe the possibilities of studying the influence of forces external variables on the stability of motion of dynamical systems modeled by systems of differential equations with periodic coefficients of stability. The method is applied to analyze the influence of external harmonic forces on the stability of motion of the pantograph couple contact wire electric ...
