Medium speed concepts:<br />
- high partial load efficiency<br />
- high drive train full load efficiency of 94%<br />
(gearbox >98.0%; generator 98.3%;<br />
frequency converter 97.5%)<br />
⇒ high energy yield at high average<br />
wind speeds<br />
Medium-speed concepts: High efficiency leads to high energy yield<br />
