In this paper the construction of a model that represents the behavior of an Electric Vehicle is described. Both the mechanical and the electric traction systems are represented using Multi-Bond Graph structural approach suited to model large scale physical systems. Then the model of the controllers, represented with a functional approach, is included giving rise to an integrated model which ex...

In Poland, rail transport is powered by the electric system with use of traction substations that supply DC voltage 3 kV. The necessity to change alternating constant and changing loads substation cause be a recipient, generating number disturbances network. These affect quality electricity in power from which are supplied, auxiliary non-traction lines. This article analyzes measurements indica...

Electric locomotive is a kind of high power rectifier load, and its load characteristics will have a significant impact to safe, stable and economic operation of power system. This paper mainly analyses load characteristics of harmonic and reactive power for electric locomotive. Simulation model of electric locomotive is set up based on time trigger; it is so better conform to the dynamic chara...
