Tropical climate effects on corona power losses on 275 kV transmission lines in the South Sulawesi system

Abstract

Electricity losses are very dependent on electric current and loss of the corona phenomenon. It is very clear that losses depend on network parameters, load behaviors and climatic factors. South Sulawesi is a tropical climate. This sector must be resistant to exposure to various factors of high tropical climate such as temperatures of 23.4⁰C-33.3⁰C, sun irradiation that occurs more than 12 hours per day, relative humidity close to 100%, and average rainfall between 440-1322 mm. This climate factors will simultaneously transmit the transmission. This text aims to connect climate factors to achieve power losses on 275 kV transmission line in South Sulawesi. The results of this study found that temperature and duration of sun irradiation affected corona power losses on 275 kV transmission line in South Sulawesi.

A new method to calculate corona losses for active conductors considering real transmission line unbalance

“…For the calculation of the critical voltage, the irregularities of the conductor are taken into account, whether it is perfectly smooth, if it is rough or aged, or if it is stranded, to give some examples. Peek's formula has been used by several authors for the analysis of corona losses [30][31][32]. It has also been used as a basis for the development of new calculation methods [22,33,34].…”
