    Sammanfattning : Information and modern computing technology advancements have led to a rise in the importance of maintenance, particularly in areas where a single components failure could have a significant impact on the overall systems performance. Numerous industries, including Alfa Laval, are operating on conditional-based systems that provide warnings only when a machine fails. LÄS MER

  5. 4. A DSO-driven evaluation of a CIM profile : Development of a CIM profile based on use cases related to monitoring Vattenfalls low voltage network

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för elektroteknik

    Författare :Louise Persson; [2022]
    Nyckelord :;

    Sammanfattning : The transition to more renewable energy sources places high demands on the power systems to be more flexible, and makes it grow in complexity. This has led to a growing need of a common format or language for data exchange in power systems because of the growing number of interconnected networks operated by different companies and utilities that need to communicate on a daily basis.
