1. Prediktivt underhåll av transformatorstationer genom automatisk analys av störningsdata i COMTRADE-filer
M1-uppsats, KTH/Hälsoinformatik och logistikSammanfattning : Arbetet beskriver möjligheten att kunna utföra prediktivt underhåll med hjälp av information frånCOMTRADE störningsfiler. En mjukvarualgoritm som hämtar tidsförlopp för händelser som uppstårvid störningar och kan ge indikationer på ifall reläer eller strömbrytare faller utanför optimalaarbetsförhållanden har utvecklats.
