Data acquisition application with implemented digital twin based on thermal and electrical parameters and state estimation of a real synchronous generator
Strøm, Fredrik Andre (Master thesis, 2023)Synkrongeneratoren er en viktig del av det elektriske kraftsystemet. Under normale driftsforhold har generatorenhetene effekttap som påvirker maskinens effektivitet og driftstemperaturer. Mekanistiske modeller av generatoren ... -
Modeling of hot-spots in transformer using analytical or numerical methods
Muneeb, Muhammad (Master thesis, 2023)Due to the increasing penetration of renewable energy sources into electrical grids, high variation of power becomes a problem for the stability of power systems. To keep the system balanced, hydro generators occasionally ... -
Optimal Scheduling for Mobile Battery Charging Systems
Wagle, Dhanush (Master thesis, 2022)A pilot project in Norway is currently being examined to give electric energy to construction sites in places where connection to the power grid is not available. This thesis proposes a generic mobile battery charging ... -
Sensitivity analysis of low voltage distribution grid in rural areas with high penetration of PV systems
Berger, Anders (Master thesis, 2022)PV systems are one of the most increasing renewable energy sources globally. In Norway, PV systems increase in amount and size, and it is becoming more critical to have solid knowledge in incorporating them into older grid ... -
Thermal model parameter estimation of a hydroelectric generator using machine learning
Melfald, Emil (Master thesis, 2020)The synchronous generator have a central role in the power system, and is governed by multi-physics behaviour. A digital twin of the synchronous generator can lead to more efficient utilization in a more safe and reliable ...
