Hi,all!
When I using the FAST simulation, I know how to create a turbulent wind profile using the TurbSim. But sometimes, I want to create a constant wind profile or a step rise in the wind. Like the following picture. How to generate this wind profile for FAST simulator?
You would want to use a hub-height wind file, where you define the wind speed, and sheer at different points in time. Here for example, is the contents of an example file “StepWind.wnd”:
!Wind file for turbine.
!Time Wind Wind Vert. Horiz. Vert. LinV Gust
! Speed Dir Speed Shear Shear Shear Speed
0.00 6.00 0.00 0.00 0.00 0.00 0.00 0.00
20.00 6.00 0.00 0.00 0.00 0.00 0.00 0.00
20.01 7.00 0.00 0.00 0.00 0.00 0.00 0.00
100.00 7.00 0.00 0.00 0.00 0.00 0.00 0.00
Dear Paul.Fleming
I have test your wind file, and it works! Thanks very much!
