Estimation of corona loss in transmission line under different weather conditions

Abstract

Electrical energy is transmitted through the electrical network from power generating station to the consumers. For this purpose, the overhead transmission line is used through which bulk power can be transferred. The conventional electrical network transmits the energy with power loss. The reason for the power loss is due to inherent characteristic of the transmission line and corona discharge which affects the performance of the transmission line. In this work, performance analysis of overhead transmission line is analyzed by developed MATLAB code and tested for different weather (fair and stormy) conditions by using peek's formula.
