2 Wind turbine<br />
The DOWEC MW6 wind turbine is a three-bladed off shore wind turbine with a rotor diameter of 129<br />
m. and a rated power of 6 MW. The turbine start up wind speed is 4 m/s and has a nominal wind<br />
speed of 12.1 m/s. Rated rotor speed is 11.84 rpm. The blades on this variable speed wind turbine<br />
are controlled by an active pitch control system. Normal pitching speed is 5º /sec. while emergency<br />
speed is 10º /sec.<br />
The hub height of the DOWEC is 91.4 m. above sea level. Total height of the tower is 110.2 m. from<br />
the sea bottom.<br />
A description of the DOWEC wind turbine can be found in ref. [3] and ref. [14].<br />
2.1 Wind turbine modelling<br />
The DOWEC 6 MW wind turbine has been modelled with the dynamic response program Phatas IV<br />
by <strong>ECN</strong>. An overview of the used program and input files can be found in Appendix A.<br />
For the simulation the DOWEC wind turbine with 21 meter foundation was used without<br />
hydrodynamic loading.<br />
