Rotor effective wind speed

Dear Jason.Jonkman, Dear All, I am trying to implement a Lidar system in feed forward CPC. Therefore, I'm trying to extract the wind speed that the turbine actually 'feels'. Lets call it here rotor effective wind speed (rews). The way I currently do that is based on a simple drive train model (J*Ome...

Re: Linking measured wind data from LIDAR to Turbsim

Dear Eric, Thanks for your support, The idea with the focus locations as time series works perfect. Now I'm looking at the range weighting along the beam (because, as you say, outputs are point 'measurements' instead of averaged LOS velocities) but no solution yet. I'll let you know if I succeed to ...

Re: FAST theory manual

Dear Jason, I would also love to have a copy of the "Unofficial FAST Theory Manual". (filip_spasof@yahoo.com) Since my Fortran skills are not excellent, I'm also currently wondering if I'll be able to extend the existing Lidar (CW) modul to 4 beams (instead of one, I'gonna try to use it af...

Re: Linking measured wind data from LIDAR to Turbsim

Dear Bonnie & All, I'm currently also trying to use the Lidar module and use its measurements for eventual FF + FB control. I think that I have followed all the possible instructions from doc's and this forum but I'm still having troubles. When I try to 'fill' the output channel WindMeas1 with s...
