“…Mahajan et al examined the relationship between contact force and contact wire displacement in the pantograph catenary system, creating a second orderindependent system model. The sensitivity analysis of pantograph parameters on the system was observed [13]. Carmine et al in this study, it was made for the optimum design of a nonlinear controller of the pantograph-catenary system.…”

Today, electric rail systems that use clean energy and are a fast and reliable means of transportation are used more because of their efficiency. The main purpose of new studies investigating pantograph catenary interaction in Electric Rail Systems is to detect malfunctions. With the spread of high-speed trains in electric rail systems, malfunctions occur in pantograph and catenary systems operating under high current and high voltage. The contact force of the pantograph-catenary system erodes the pantograph surface and arcs occur. For this reason, periodic control is mandatory in pantograph-catenary systems. In this study, new, effective, sensitive, stable, real-time applicable and contactless condition monitoring, analysis, control, and diagnostic methods were investigated for pantographcatenary systems that provide energy transmission from the electric line to the locomotive in electric trains. A literature search and study application after has been carried out for modeling a pantograph-catenary system and analysis of system parameters, instantaneous control of the contact force between the pantograph and catenary to diagnose malfunctions in the pantograph-catenary system. It has been observed that pantograph-catenary interaction is negatively affected and the quality of energy transmission decreases if the system parameters change for any reason. In pantograph-catenary systems, the importance of periodic pantograph control, which will ensure the stable and efficient operation of the system, is understood if the parameters change. Because changes in parameters cause malfunctions. Therefore, periodic control and continuous monitoring of the system is required.

The pantograph-catenary (PAC) system is one of the important interfaces between supply system and loco drive. The aim of this paper is to develop an electrical analogous of the mechanical model of PAC system. The response of the developed analogous electrical model and mechanical model are compared using simulink. Further, the hardware prototype of this electrical analogous of the PAC system is fabricated on a PCB using electric circuit elements and the response of hardware prototype and the developed electrical simulink model are compared. This model shall be useful in the designing and testing of PAC system.

Pantograph-catenary contact (interface) is the most crucial link to supply electrical power to loco drive. At high train speed, the loss of contact may occur due to the vibrations between the pantograph and catenary. In this paper, the fuzzy logic control is applied to minimize the vibrations in the force using different membership functions using MATLAB-Simulink software and the response is compared with PID controllers.
