The iSpin technology at the spinner allows owners to accurately measure the most important input parameter of wind turbine operation: the wind speed and direction. This allows operators to determine undetected yaw misalignment. After correcting the yaw misalignment, owners can tap the full potential of the wind turbines, reduce damaging loads, and decrease repair cost.
Combining yaw misalignment with turbulence intensity and inflow angles in all wind sectors, the iSpin technology turns the wind turbines into virtual wind met masts. Finally, the iSpin technology is capable of determining IEC compliant power curves as well as performance monitoring during operations of the wind turbine life time.
