A software computing suite for simulating effects from coronating wires of overhead AC lines

Due to the development of electrical networks of high and extra-high voltage and ultra-high voltage, the issues of the environmental impact of high-voltage power lines are becoming relevant. There is an urgent need to develop software for assessing (monitoring) the electromagnetic compatibility of overhead lines. It will make it possible to assess the impact of high voltage AC transmission lines on the environment. The paper considers mathematical modeling of the influence of overhead line wires, electromagnetic interference, corona discharge, radio interference in wires. It also describes a developed program for calculating power and energy losses due to corona in overhead lines of ultra-high AC voltage. To calculate the capacitance of overhead line phases, there is a method for determining the working capacitance of wires for a horizontal arrangement of wires and two grounded cables. There is a developed electromagnetic compatibility software to use for taking measures aimed at reducing the electric field of extra-high voltage overhead lines. The paper gives the example of overhead lines with 500 kV voltage, which presents the results of a com-plex system for modeling corona losses, electric field voltage and active energy losses due to radio interference.
