ROTOR BLADE CONTROL BASED ON DETECTING TURBULENCE

Title:

ROTOR BLADE CONTROL BASED ON DETECTING TURBULENCE

Document Type and Number:

WIPO Patent Application WO/2011/015383

Kind Code:

A3

Abstract:

A control system for rotor blade control is discussed. The control system comprises a number of turbulence sensors provided across the surface of a wind turbine blade. The control system monitors the turbulence sensors and when turbulent air flow is detected controls an aerodynamic parameter of the of the blades. In one embodiment, the parameter is the pitch of the rotor blades. This means that stall-like blade conditions can be avoided, and power generation from the wind turbine can be optimised. The control system may also use measurements of output power as a control system to which the turbulence based measurements add extra responsivity and finer control.
