“…The analysis and design of power and signaling system of railway electric traction system needs mathematical model of the system. The authors have used the multi-conductor transmission line (MTL) theory to develop the mathematical model of the electric traction system and to compute the characteristic impedance and propagation constant of this system [1,2,5]. In a railway traction system, the individual lines corresponds to each running rail/rail track conductor and the power conductor or overhead catenary are as shown in Fig.…”

“…Most of the traction studies are limited to analog railway track modeling. Mahajan et al [2] has developed the analog model of railway traction lines using multi conductor transmission lines (MTL) theory and computed the characteristic impedance and propagation constant of the lines. Hill and Carpenter [3] have computed frequency dependent self and mutual admittance for a single track power-rail, considering it as a distributed transmission line.…”

The characteristic impedance and propagation constant define the behavior of signal propagation over the transmission lines. The digital model for railway traction lines which includes railway tracks is developed, using curve fitting technique in MATLAB. The sensitivity of this model has been computed with respect to frequency. The digital sensitivity values are compared with the values of analog sensitivity. The developed model is useful for digital protection, integrated operation, control and planning of the system.

The modal analysis, which decouples the contact wire and rail track conductors, is used to develop an integrated model of single rail track and contact wire. The characteristic impedance and propagation constant matrices of integrated model have been computed. The authors have studied effects of various parameters of interest on characteristic impedance and propagation constant using sensitivity analysis. The sensitivity functions of series impedance and shunt admittance related to contact wire and catenary have been developed and validated in this paper.

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.
