13.2.4 Adjustments to Multiple Masts
Most numerical wind flow models are equipped to use data from just one mast. These
days, however, wind projects usually employ several masts. This raises the question
of how to make the best use of the additional data. Since any blending of predictions
from different masts is done in most cases in the plant design software rather than in
the wind flow software, this topic is addressed in Chapter 16.
13.3 QUESTIONS FOR DISCUSSION
1. Suppose you are developing a conceptual model for a wind project on a ridgetop
site. Would your model assume that the wind speeds increase or decrease with
Figure 13-7. Examples of preferred and poor mast placement for a hypothetical turbine layout.
The four masts in the lower left-hand corner, indicated by black dots, are poorly situated for
this proposed turbine array. The single mast near the center of the array (red dot) is better
situated, but since it is on the highest ground, it may not accurately capture the wind resource
for some turbines at lower elevations, even with numerical wind flow modeling. Source: AWS
