The phenomenon of corona and its effect on the transient wave in the transmission line

الملخص

Abstract: Corona effect has been considered as a source of substantial loss due to High Voltage AC Transmission lines. This paper presents a comprehensive account of development of a mathematical model for the Corona Effect which is designed based on the Peek’s equation. The scope of this work is determining the corona power losses dependent on conductor’s diameters. The simulation is completed using the corona model for 220 kV overhead transmission lines which were developed by Matlab/toolbox (release 2010). The corona effects analysed in high voltage transmission lines, and factors of decreasing the corona losses have been identified. Factors such as increasing the diameter of conductors those lead to increase the critical disruptive voltage. The paper describes the analytical approach, computational tools and simulations models.
