“…Due to the temperature dependent heat generation rate the nonlinear system of equations is obtained. The Jacobi Iteration method [45] is applied to solve the nonlinear system and determine the nodal temperatures. The ground level temperature (T g ¼ 30 C) is assumed as the starting values for Jacobi Iteration procedure.…”

Abstract. The paper presents a mathematical model of heat transfer in the underground cable system. The computations were performed for flat formation of power cables buried in the ground at a depth of 2 meters. The model allows determining the two-dimensional temperature distribution in the soil, thermal backfill and power cables. The simulations studied the effect of soil thermal conductivity on the maximum temperature of the cable conductor. Furthermore, the effect of thermal backfill soil conductivity on the cable conductor temperature was studied. Numerical analyses were performed based on a program written in MATLAB.

This paper presents losses distribution in power cables conductors and metallic sheaths. Losses are computed in sinusoidal and non‐sinusoidal currents with considering all sequences harmonics. Two numerical methods as finite element and integral method are used to determine the distributions and also total harmonic losses. Thus skin and proximity effects of all metallic parts of cables are considered accurately. Integral method is utilized for losses calculation by considering of earth return path and eliminating it. Furthermore, IEC formulations are used for losses computations. Numerical results suggest inserting the earth return path effect on cable losses in some harmonic frequencies of currents. Power cables are assumed to be single core medium voltage type. Lead sheaths of cables are bonding together and grounded at both ends for calculation of circulating current losses. Also the effects of different distances between cables in losses calculations are assessed. For validation of integral method, finite element simulation, as proven method in accurate power cable losses computations is used. These methods are completely described in this paper. Accuracy of integral method for harmonic losses computations of conductor and sheaths is verified by finite element simulation results. Also it is shown that proximity and skin effects are considered very well by integral method even in metallic sheaths. © 2016 Wiley Periodicals, Inc.
