Doppler wind lidar development at University of Oldenburg

摘要

For future multi-megawatt wind energy converters (WEC) in large-scale offshore wind farms new and advanced control strategies are required. Dynamic wind loads have to be reduced efficiently and with minimal controller operation, in order to deliver electricity to the grid in an optimized way. Up to now the implementation of these visions suffers from fundamental obstacles, despite the progress in many fields of wind energy technology. Large uncertainties due to the complex inflow within the rotor area influence the control and operation of wind energy converters. This problem becomes even more serious with growing rotor diameters beyond 120 m. Current control concepts can only react to wind field fluctuations which have already caused changes in rotational speed or loads.
