Sažetak
All power lines can be modeled with finite elements technique if replaced by cylindrical segments of final length. In practice, they may be cylindrical sections of a guide buried in the ground. These guides are buried above the cable lines, between the grounding poles of overhead lines, external metal sheathing of power cables
and any naked full or hollow guide buried in the ground. Also, wires mesh grounding power facilities can be approximated by a network of cylindrical segments guide. Cylindrical segments wires in the air can be earthing cable lines and the phase conductors of overhead lines and pole overhead line. The paper presents a method of introducing an approximation and calculated impedance of cylindrical segments wires modeling with finite element technique and Bubnov-Galerkin method, which is applied to the integral formulation of the problem in the frequency domain. On this basis is developed a computer program used for the analysis of the electric power plants and a concrete example of the calculation is presented.
