Analysis of the influence of weather factors on outages in Spanish distribution networks

The origin of outages occurring in a power distribution network are highly related with the weather conditions existing during its apparition. Wind, rain and lightnings usually are the trigger causes of power network outages, hence the analysis of the relationship between weather and network outage information plays an important role for forecasting the impact of future weather conditions in the power distribution network. In this paper, weather information and distribution-network outages collected during three years are studied and statistically analyzed. From the analysis some useful relationships between weather conditions and network outages were extracted.
