Abstract

Advantages of downwind configuration in yaw measurement were shown to be advantageous in complex terrain, in both aspects of energy production and fatigue damage. CFD showed the nacelle-to-yaw sensor interference of the upwind configurations is significantly stronger than that of the downwind. Yaw measurement error in 8deg of actual yaw angle with 16deg of inclination was calculated as 6deg in the upwind configuration, whereas about 0.2deg in the downwind configuration. A case study showed the error affects 1% reduction in annual power production and more than 10% increase in fatigue damages for some loads.
