Re: Learizing Baseline 5MW Wind Turbine with FAST

Thank you very much Mr Janson for your clear response, really it help me well to resolve the problem
However it still some informations to know:
the equivalent inertia of the wind turbine of 5MW (if we consider it as a lumped mass)=Hub inertia+Nacelle inertia or what

Re: Learizing Baseline 5MW Wind Turbine with FAST

Thank you very much Mr Janson for your clear response
It still me a thing from your previous speech "run multiple cases and take the time- (or, preferably, azimuth-) averaged torque", what you means by multiples cases ? and how i can average the torque on the azimuth rather than time?

Re: Learizing Baseline 5MW Wind Turbine with FAST

Ok so if i would like to works on the 5MW i should parameters firstely the file.dvr( Numblades=3,HubRad=1.5,HubHt=90;for Overhang,ShftTilt,Precone i change their values or not?); and I use the aerodynamique file with Airfoils and the balde file given in the archive as it is or i must change somthing...

Re: Learizing Baseline 5MW Wind Turbine with FAST

thank you very much for your very helpful response But it still me some ambiguities For example i have run the simulation and the results are follew Predictions were generated on 10-Mar-2016 at 19:23:52 using AeroDyn_driver (v1.00.00-bjj, 7-Oct-2015) AeroDyn (v15.00.00b-bjj, 6-Oct-2015) Case 1: WndS...

Re: Learizing Baseline 5MW Wind Turbine with FAST

Thank you very much for your reply Mr Janson.It is exactly what i want to calculate the the aerodynamic torque as a function of the wind speed and the retational speed. Enable me to ask you how to extract these coefficient.I have read the document that you have provide me and i have did the simulati...

Re: Learizing Baseline 5MW Wind Turbine with FAST

Thank you verry much for your help Mr Bonnie Now I would like to peform a linearization of the system WT around differents operating points ( the operating point is fixed by the wind speed) so at each fois i use a step of wind speed. Firstely i did the modification in the input file(anallmode=2,PCMo...

Re: Learizing Baseline 5MW Wind Turbine with FAST

Hello In order to realize a linearization of 5MW NREL i have a problem related to the wind profile I choose the step wind profile of 12, so i included it name in both ijn the input file and the aerodyn.ipt file, of course i specified the linear file and the modification nedded in the input Bref when...

Re: Simulation of an offshore Wind turbine 5MW based DFIG

Thank you very much for your help, its solved because i have used a 32 bit in 64 system Tell me to share with you an other error, this time i thought related to the wind speed profile In fact, i have searched on this kind of mistake and i found its response such as given in this link https://wind.nr...

Re: Simulation pf a offshore Wind turbine 5MW based DFIG

Hello dear Jonson
Thank you very much for your reply
Exactely i dont did attention to the format that you talked,I just created a simple wind profile as this attached
In fact, samply i would like to simulate my system with a simple profile (a step wind speed) tell me please how i can do
