Effect 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 کاملThe 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 کاملGDL construction effects on distribution of reactants and electrical current density in PEMFC
In this article, a two dimensional pore scale model of polymeric fuel cell, which is promising of a clean and renewable energy production, is presented here. Let reactive gases behave as an ideal gas; inhomogeneous anisotropic structure of the gas diffusion layer, is contemplated as a random generated circular porous media. Lattice Boltzmann method is applied to inquire the fluid flow and mass ...
متن کاملCharge Density in a Current-Carrying Wire
Discussions of the force on a charged particle outside a current-carrying wire often assume that the wire is electrically neutral. This problem explores how this assumption is not quite correct. We give solutions both in the lab frame and in the rest frame of the conduction electrons, using both Maxwell’s equations and special relativity. We note that for current to flow in a resistive wire, th...
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...
