Gear-less wind power system has blade angle adjustment for active vibration damping in drive train, and no mechanical gears but slow synchronous generator directly driven by wind wheel

摘要

The system has a synchronous generator directly connected to the mains and active damping of vibrations in the drive train by influencing the drive torque by twisting the rotor blades (4) about their longitudinal axes. The system has no mechanical gears subject to wear and play but a slow-turning synchronous generator directly driven by the wind wheel.
