6 FAQs about [Automatic wind alignment of wind turbines]
How to detect a change in the alignment of Tur-Bines?
Current methods to detect a change in the alignment of tur-bines are based on wind direction in situ comparison in case of redundancy of the device on the nacelle or by compar-ing wind direction measurements nearby (e.g., other turbines, met masts or lidars). The absolute wind directions of one or more wind vanes in the neighborhood are compared.
Which control system allows a correct alignment of a wind turbine?
The control system that allows a correct alignment of the wind turbine with respect to the incident wind is the yaw control. A detailed explanation about the yaw control system of a 5 kW wind turbine is introduced in the work of Yücel and Özder [ 14 ].
Do upwind horizontal axis wind turbines need to be aligned?
Upwind horizontal axis wind turbines need to be aligned with the main wind direction to maximize energy yield. Attempts have been made to improve the yaw alignment with advanced measurement equipment but most of these techniques introduce additional costs and rely on alignment tolerances with the rotor axis or the true north.
What is a wind turbine yaw control strategy?
The objective of the designed control strategy is to achieve, after a training stage, a fully autonomous performance of the wind turbine yaw control system for different input wind scenarios while optimizing the electrical power generated by the wind turbine and the mechanical loads due to the yaw rotation.
What are the advantages of a new wind turbine alignment method?
With this new method, two mayor advantages are achieved, compared to the marked solutions mentioned in the introduction. Firstly, the turbine alignment is not relying on multiple wind direction measurements which reduces uncer-tainties caused by the challenge of finding true north.
Why is it difficult to align a turbine with the wind direction?
Achieving a good alignment of the turbine with the wind direction is difficult for the following reasons. On standard turbines, wind speed and wind direction measurements take place behind the rotor. This leads to flow distortion caused by the rotor blades and the nacelle.
