Analysis of transient voltages and currents in short transmission lines on frequency-dependent soils☆
(2021-05-01)
Accurate modeling of overhead transmission lines (OHTLs) for transient analysis require that the ground which the phase conductors are suspended be considered on the longitudinal impedance and transversal admittance matrices. ...
Power flow in distribution networks with earth return
(Elsevier B.V., 2004-06-01)
The problems of wave propagation and power flow in the distribution network composed of an overhead wire parallel to the surface of the ground have not been satisfactorily solved. While a complete solution of the actual ...
Assessing Closed-Form Approximations for Underground Cable Earth Impedances
(2003)
Electromagnetic transients on underground power cables are highly influenced by the natural resistivity of the ground. Modeling earth-return impedances of a system may properly consider the resistive losses due to the ...
Computation of Surge Voltage in Transmission Tower Located above Frequency-Dependent Soil
(2021-01-01)
The purpose of this paper is to investigate the influence of frequency-dependent soils with variable soil content on the transient voltages at transmission towers. First, a comparative analysis between the impedance of ...
