Investigation of struction dynamics on the Gedser WTG and on new Danish wind turbines

摘要

A survey is given of activities on Rise National Laboratory related to structural dynamics of large WTG's. Since only few of the activities have yet been completed, the presentation is a review of status, preliminary conclusions and experience. The topics dealt with in the presentation are:n- Analysis of prototype WTG rotorsn- Analysis of the Gedser WTC rotorn- Measurements on the Gedser WTGnInvestigations being made of the power train oscillations in the Gedser WTG are dealt with in some detail.
