Power losses on overhead lines under various loading regimes and weather conditions

Abstract

The paper will present the first results of an extended analysis based on synchronously recorded electrical and weather data, aimed to numerically evaluate the stochastic variation of transmission power losses measured on a given 400 kV line, in correlation with different environmental influence factors such as air temperature and pressure, dew point, wind speed and direction, type and amount of precipitation reported at 14 meteorological stations.
