The main objective of this project is to develop algorithms, that enhance the nacelle or spinner-based Lidar systems to be more intelligent, reliable, and adjustable thus providing better signals to the wind turbine control system. This project investigates how to use wind preview for lidar-assisted wind turbine control. Only data collected by the turbine-mounted lidar system will be explored. Innovative filter algorithms will be developed and tested, and to be as independent as possible, the algorithm developed will be implemented on a separate hardware (industrial pc) during the project. It is crucial to filter the signal quality to avoid unnecessary and harmful control action and to provide the signal at the right time to avoid that the turbine reacts too early or too late.
