• Use centrifugal load to pitch blades to<br />
reduce efficiency<br />
• Need preloaded spring or equivalent<br />
• Fixed pitch at all times below rated power<br />
• Aligned with wind direction at all times<br />
• Since pitch system has low inertia, so<br />
response is rapid<br />
• Easier to get it wrong!<br />
bringing wind energy to life<br />
Passive pitch regulation<br />
Efficient below<br />
rated power<br />
Minimise<br />
fluctuations in<br />
load in high winds
