Abstract
In this paper a new efficient algorithm for computation of corona power loss in grid is described. The algorithm is based on a new finite element method (FEM) which allows computing corona power loss in high-voltage lines transmission. The new algorithm method is intended for considering the effects of various parameters on corona current such as: the height of conductor, the radius of conductor, the surface factor, distribution of electric potentials in space of between conductor and ground plane with applying space charges, and ambient temperature. The algorithm results were compared with the existing methods and the result accuracy was confirmed. Also, the results show that the new algorithm has positional to reduce the number of iteration for calculation of the corona current. The knowledge of the corona phenomena discharge will assist in monitoring and controlling the reliability of high voltage systems. This information can be monitored for measuring, detecting and taking appropriate control actions.
Highlights
According to a report from the Department of Energy, California two major sources of loss in high voltage AC transmission lines are: resistive and corona loss [1]
Aboelsaad et al [7] used the numerical assessment of unipolar corona ionised field quantities using the Finite Element Method (FEM) that deal only with the potentials in conductor and ground plane and check the field only on conductor surface later
The method attempted a solution of only one secondorder Partial Differential Equation (PDE)
Summary
According to a report from the Department of Energy, California two major sources of loss in high voltage AC transmission lines are: resistive and corona loss [1]. Corona loss (2.89%) is an ionization of the air that occurs when the electric fields around a conductor exceed a specific value. Based on the above method [8] Mohammadi and Ebrahimi [9] compared the corona losses power for high voltage AC and DC. Most of the existing works do not take into account the effects of various parameters on corona current such as: the height of conductor, the radius of conductor, the surface factor, distribution of electric potentials in space of between conductor and ground plane with applying space charges, and ambient temperature impacts on corona phenomena
