4. 3. The Paradigm Shift for Substations Technology within Wind Power Applications from Onshore to Floating

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Ahmad Talaat Hifzy; [2023]
   Keywords : Floating; offshore; substation; transformer; GIS; equipment; high-voltage; fatigue; Flytande; havsbaserad; station; transformator; GIS; utrustning; högspänning; utmattning;

   Abstract : Floating wind turbines are attracting more attention as more than three-quarters of the total offshore technical potential is located in deep water, leading to a growing trend in floating wind farm projects. Consequently, it becomes necessary to develop Floating Offshore Substation (FOSS) to step up voltage and efficiently transmit power to the shore with minimal losses. READ MORE
