Appl.No PCT/NL2007/000030 Applicant PANTHEON BV Inventor SCHÜRMANN, Luc, Joseph, Charles
The invention relates to a wind turbine tower vibration damping method wherein during normal operation, when it is detected that the deflection of the tower reaches or passes a predetermined safety level, the aerodynamic drag at the top part of the tower is changed. For that, the pitch of the rotor blades is changed, preferably simultaneously over the same pitch angle. When the tower is deflecting upstream, blade pitch is changed towards stall. When the tower is moving downstream, blade pitch is changed away from stall. The wind turbine is provided with accelerometers, strain gauges, inclination meters, speed sensors or acoustical or optical scanners that communicate with an automatic control system to carry out the damping method.

In order to increase the power generated by a windmill by 10 to 20 times, you will have to increase the number of wheel by 10 to 20 times on both sides of the post.

The wheels will be welded to the same shaft that turns to generate power.

The wheels and the shaft will be similar to an air turbine.
