1. 21. Improving maintenance scheduling with condition monitoring on the electric distribution grid : An economic analysis comparing corrective and predictive maintenance

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Hugo Vincenti; [2022]
   Nyckelord :Condition-based maintenance; predictive maintenance; health index; failure rate; maintenance scheduling; sensors; economic analysis; simulation; Tillståndsbaserat underhåll; förebyggande underhåll; hälsoindex; felfrekvens; underhållsplanering; sensorer; ekonomisk analys; simulering.;

   Sammanfattning : A growing use of sensors on the electric grid has opened the door to new methods of asset management: Distribution System Operators are now looking into conditionbased maintenance, as opposed to the traditional corrective or time-based methods. As an emerging field, the methodology must be constructed from the ground, with the little data available. LÄS MER

   Sammanfattning : Within the company Infinera, there is a need for an improved thermal design of an existing chassis product for use in telecommunications for distribution of services within the Edge & Metro network. To enable an optimized airflow design of the chassis, there is a need of analyzingdifferent simulation cases performed in FloTHERM. LÄS MER

4. 23. Power systems with local PV-generation and battery storage for peak shaving to provide flexibility services to the utility grid

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

   Författare :Vincent Jansson; [2022]
   Nyckelord :Peak shaving; power peaks; flexibility services; flexibility markets;

   Sammanfattning : Due to the increased demand for electricity in recent years and the estimated demand in the future it has become clear that the capacity of the Swedish electrical grid is insufficient, and the grid is not able deliver the amount of power that is demanded by the market. The crucial points in the grid where the grid capacity is insufficient could be several. LÄS MER
