Title: Development, Field Testing, and Evaluation of LIDAR-Assisted Controls

Abstract

Typical wind turbines utilize feedback controllers which have a delayed response to wind speed disturbances. A nacelle mounted LIght Detection and Ranging (LIDAR) system measures a preview wind signal in front of the turbine. This can be included in a feed-forward control system, improving turbine pitch command for incoming variations in wind speed. The overall aim is reduced blade and tower fatigue, and potentially improved annual energy production. To be successful, the LIDAR must yield accurate wind speed measurements. Therefore, a LIDAR was characterized against a nearby met tower and turbine wind speed estimator. Results indicate good correlation between measurements.
