Comparision of Thyristor-Controlled Rectification Topologies for a Six-Phase Rotating Brushless Permanent Magnet Exciter
Nøland, Jonas Kristiansen; Hjelmervik, Karina Bakkeløkken; Lundin, Urban (Journal article; Peer reviewed, 2016)The thyristor bridge rectifier has proven to be a reliable solution regarding control of excitation equipment for synchronous generators. However, in rotating brushless exciters the diode rectifier is the dominant topology ... -
Enhanced Power Capability of Generator Units for Increased Operational Security using NMPC
Øyvang, Thomas; Nøland, Jonas Kristiansen; Sharma, Roshan; Hegglid, Gunne John; Lie, Bernt (Peer reviewed; Journal article, 2019)The ever-increasing penetration of intermittent energy sources introduces new demanding operating regimes for the bulk power generation in the power grid. During a worst-case power system disturbance scenario, the generator ... -
Future Operational Regimes of Bulk Power Generation in The Era of Global Energy Transition: Grid Codes, Challenges and Open Issues
Nøland, Jonas Kristiansen; Leandro, Matteo; Nysveen, Arne; Øyvang, Thomas (Chapter, 2020)This paper explores the effects of the ongoing energy transition on the classical bulk power generation. The rapid increase in renewable penetration changes the role of grid-connected generators significantly. Large machines ... -
Stator Flux-Regulatory Excitation Control in Converter-Fed Synchronous Machines for Pumped-Storage Variable-Speed Hydropower
Stavnesli, Jørgen Hagset; Nøland, Jonas Kristiansen (Peer reviewed; Journal article, 2022)Pumped-storage hydropower is seen as a promising solution for efficient, large-scale energy storage. One competitive technical solution is the variable-speed hydropower plant (VSHP) configured with a converter-fed synchronous ... -
Systemdrift 2020
Christoffersen, Fredrik Vigeland; Handeland, Tine; Grande, Tove Rømo; Nøland, Jonas Kristiansen; Øberg, Martha Marie; Ødegaard, Leiv Erik (Research report, 2012)KUBE 2012 har i årets sommerprosjekt svart på problemstillingen: Hvordan bør Statnett drifte kraftsystemet i 2020? Utviklingen av systemdriften frem mot 2020 vil drives av en kraftig økning i utvekslingskapasitet mot ...
