Active Blade Pitch And Hull-Based Structural Control Of Floating Offshore Wind Turbines, Eben Lenfest
Active Blade Pitch And Hull-Based Structural Control Of Floating Offshore Wind Turbines, Eben Lenfest
Electronic Theses and Dissertations
Floating offshore wind turbines (FOWTs) have the potential to bring renewable energy to waters too deep for traditional offshore wind turbines while still being able to harness strong coastal winds in areas near population centers. However, these floating wind turbines come at a higher capital cost relative to fixed foundations and are more susceptible to vibrations induced by waves. Advances in control technologies offer the potential to reduce fatigue loads due to these vibrations, extending the life of the platform and thereby spreading the capital costs of the turbine over a longer period of time. One such advance is in …
Characterization Of A Wind Tunnel For Use In Offshore Wind Turbine Development With Mitigation Measures For The Wall Effect Of Proximal Structures, James Newton
Electronic Theses and Dissertations
This thesis supports the development of the Harold Alfond W2 Ocean Engineering Laboratory constructed at the University of Maine through several investigations conducted with a one-third scale wind generation system. The scale wind generator is first tested in what is considered an open-circuit wind tunnel configuration to determine the influence proximal building walls of a facility housing such a device may have on the consistency and capacity of a wind generator. Turbine performance testing with the wind generator to identify any susceptibility to proximal wall influence is also conducted. This is of interest as the full-scale system will operate …
