Structural Control Of Offshore Wind Turbines Using Passive And Semi-Active Control, Semyung Park Oct 2019

Structural Control Of Offshore Wind Turbines Using Passive And Semi-Active Control, Semyung Park

Doctoral Dissertations

Offshore wind energy has the potential to generate substantial electricity production compared to onshore locations, due to the high-quality wind resource. Offshore wind turbines must endure severe offshore environmental conditions and be cost effective, in order to be sustainable. As a result, load mitigation becomes crucial in successfully enabling deployment of offshore wind turbines. A direct approach to reduce loads in offshore wind turbines is the application of structural control techniques. So far, the application of structural control techniques to offshore wind turbines has shown to be effective in reducing fatigue and extreme loads of turbine structures. However, the majority …


The Optimization Of Offshore Wind Turbine Towers Using Passive Tuned Mass Dampers, Onur Can Yilmaz Aug 2014

The Optimization Of Offshore Wind Turbine Towers Using Passive Tuned Mass Dampers, Onur Can Yilmaz

Masters Theses

Increasing energy demand and carbon emissions have driven the development of alternative energy solutions. One promising technology is wind energy. Wind energy technology developments has advanced substantially since the 1980s. Offshore wind turbines have become a major research focus, due to the promising offshore wind resource. However, challenges in offshore wind energy have arisen due to the additional wave loading and strong wind loads. Structural control systems have been implemented and researched in order to decrease dynamic response of these systems. The previous studies were successful at decreasing fatigue loads in the tower and support structure of offshore wind turbines. …


Load Reduction Of Floating Wind Turbines Using Tuned Mass Dampers, Gordon M. Stewart Jan 2012

Load Reduction Of Floating Wind Turbines Using Tuned Mass Dampers, Gordon M. Stewart

Masters Theses 1911 - February 2014

Offshore wind turbines have the potential to be an important part of the United States' energy production profile in the coming years. In order to accomplish this wind integration, offshore wind turbines need to be made more reliable and cost efficient to be competitive with other sources of energy. To capitalize on high speed and high quality winds over deep water, floating platforms for offshore wind turbines have been developed, but they suffer from greatly increased loading. One method to reduce loads in offshore wind turbines is the application of structural control techniques usually used in skyscrapers and bridges. Tuned …
