Feed-forward pitch control of HAWT using LIDAR

Research output: Contribution to conferencePaper

Abstract

The prediction of wind speed is increasingly interested in the recent wind turbine control studies. The developing LIDAR technology, fully named Light Detection And Ranging, provides the possibility to mount the LIDAR device on the nacelle to collect wind data a certain distance in front of the rotor plane of the turbine. These data are fed into the Feed-forward control system. It is demonstrated by many previous researches that the LIDAR-Feed-forward system provides an advanced turbine performance, including a better energy capture and the reduction of fatigue and extreme loads.
Although the improvement of LIDAR size and reliability brings a possibility of using LIDAR in wind energy, the additional cost requires an accurate assessment of this possibility.
This paper indicates a series of statistical analysis by using unfrozen turbulence model simulations.
