A Numerical Study to Verify the Effects
The sensors for yaw control are usually located on top of the nacelle of horizontal axis wind turbines (HAWTs). However, because of the different relative positions of the rotor and the tower in upwind and downwind HAWTs, the position of the nacelle yaw sensors will also be reversed. Research has been carried out to quantify the effect that different factors have on the efficient running of the turbines in complex terrains and the results are presented in the following article.
