Simulation of Induced Energy Distribution Processes in the Ground Wire Cable of High-Voltage Overhead Power Lines

Abstract

Experimental studies have been carried out on High-Voltage Overhead Power Lines (HVOPL) in order to determine the energy characteristics of the induced energy in the ground wire cable, taking into account the peculiarities of its grounding. The experimentally obtained results have been used in the development of simulation models of the HVOPL-500 sections located between the anchor supports. Simulation models of the anchor span with different numbers of supports have been built. As a result of simulation experiments, the dependences of power consumption as a function of the load resistance and voltage across the ground wire have been obtained. Based on the obtained dependences, recommendations have been developed for various options of power supply for the telemetry system components placed on the HVOPL-500 kV supports. In the course of simulation experiments, the maximum values of power and the corresponding voltage values on the ground wire as a function of the load resistance value have been determined. Technical solutions and recommendations have been proposed for providing power supply to the components of diagnostic systems and monitoring the state of structural elements of the supports.
