The interaction between pantograph and catenary is the present problematic of current collection in electrical railways. Current collection enhancement is a key requirement for train speed-up in railway industry. Several models have been proposed in this sense to investigate the dynamic response of pantograph-overhead contact line. This paper presents a review of different pantograph and catenary models. More attention is paid to catenary models in order to evaluate its implementation on a real-time system. The accuracy is compared based on European Standard EN50318-2000 and the computation time between all realized models is also discussed.

“…As far as the control strategies are concerned, investigations have bee carried out on the configuration of two pantographs [15], [16], [17], [18], also from the point of view selection of signal suitable for feedback. In the quoted papers Kalman filter is used in spite of the direct measurements of the contact force, in order to overcome the main difficulties arising in treating the disturbance that affects the force signal.…”

In the present paper an alternative way to apply active control on a high speed train pantograph is proposed. The control is based on two main concepts: the use the incident air flow on the pantograph as power source, and the application of the control force directly on the collector, i.e. where it is immediately required for the modification of the contact force. The feasibility of such a solution has been evaluated through wind tunnel tests, concerning the aerodynamics of the device, and by means of simulation of pantograph-catenary interaction, for the control strategy

In this study, the dynamic response of a catenary system that supplies electrical power to high -speed trains is investigated. One of the important problems which is accompanied by increasing the speed of a high-speed rail, is the performance of stable current collection. Another problem which has been encountered, is maintaining continuous contact force between the catenary and the pantograph without loss of panhead. The dynamic analyses of the catenary based on the Finite Element Method (FEM) are performed to develop a pantograph suitable for high speed operation. The static deflection of the catenary, the stiffness variation in contact lines, the dynamic response of the catenary undergoing the force of a constantly moving load and the contact force were calculated. It was confirmed that a catenary model is necessary to study the dynamic characteristics of the pantograph system.
