Design Scheme Of The Supporting Structure 3MW Monopile Wind Turbine

Energy problem is an important problem every country faces all over the world, as oil, coal, gas is consumed gradually and environment problem is becoming more and more serious, people pay more attention on wind turbine especially offshore wind turbine. Offshore wind turbine supporting structures suffer harsher environment load than those on land, for example: wave load,stream load. There are several kinds of supporting form, this dissertation choose a simple one-monopile wind turbine as research object. First, this dissertation used software SACS to model the supporting structure to get a design scheme. Then I make the speed of wind as a variable, I can got the dynamic loads, make the dynamic responses of structure with ANSYS, including modal analyze,harmonic analyze and transient analyze. The result of dynamic responses was used to optimize the original size of structure. We can see the differences of the structures between static loads and dynamic loads. Check the structure with rules of API and DNV at last.
