“…By using a digital computer, the transient analysis and the modeling of underground cables have been a considerably interesting subject in recent years. After using of the digital computer, many methods have been investigated to analyze the transient analysis of underground cables such as Fourier transform [2,3], z transform [4][5][6], weighting method [7], 1 Sakarya University, Electrical and Electronics Engineering, Sakarya, TURKEY.

In this work, the transient overvoltage phenomena occurred at 34.5 kV AC underground cable transmission systems during the closure of the underground cables is to be studied and simulated by using the MATLAB program. Then, the transient voltage occurred at the underground cables is analyzed by using a modified Fourier transform. The studied system of underground cables is firstly modeled in the frequency domain. Transient voltages induced at the sending-end and receiving-end terminals of an underground cable of the transmission system are calculated in the frequency domain and using inverse Fourier Transform, the sending end and receiving end voltages are obtained by converting to the time domain. The effects of Gibbs factor on transients overvoltage phenomena considering cable length and source impedance are investigated. Numerical simulations are presented to demonstrate the transient voltages induced at the terminals of sending-end and receiving-end of an underground cable at the transmission system and the effects of Gibbs factor to eliminate Gibbs oscilllations.

“…It consists of a regular transposition of the metallic sheaths, analogous to the transposition of phases in overhead power lines. A crossbonding point causes refraction/reflection of a travelling wave on the cable system resulting in higher sheath overvoltage [8,[10][11][12][13]21]. An accurate transient simulation must therefore account for the crossbonding of sheaths.…”

“…Mariscotti [5] has also applied MTL theory to railway traction system for finding the distribution of the traction return current in ac and dc electric railway systems and carried out sensitivity analysis of rail current and rail to rail voltage with respect to parameters of interest. Though not much work is done in the digital modeling of railway traction system, Humpage [6][7][8][9] is the pioneer in using the z-transformation in power systems. He along with Wong and Nugyen has applied this technique for analysis of the transient in overhead lines and cables.…”

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.
