Re: Output - Wind speed

Dear Dr Jonkman
thanks
But the main problem is that there is no file related to InflowWind module in the directory
of FAST V8.10 that I am using.

Best regards

Re: Output - Wind speed

yes, of course; this is the picture taken from pdf file "InflowWind User’s Guide".
I am wondering whether I should make this file myself or there exists in some packages
provided by NREL.

Your sincerely

Re: Output - Wind speed

Many thanks for your answer. Another problem is that I could not find primary file related to inflow module.
The one I attached herewith.

Output - Wind speed

Dear All; Hi I am using FAST V8 in simulink to simulate 5 MW WT. There is a problem: Actually, while simulationg I cannot see wind speed as one of the outputs. what I am observing is that wind speed is kept constant at zero although simulation is done based upon the wind speed generated by Turbsim. ...

Re: Tip Speed Ratio

Dear Dr Jonkamn Thanks Since you discussed linearization, I confused that it relates to that, but now I understand. Anyway. the issue is that I need to have a simulation while TSR is sweeping the interval [3:15] rather than only regulating to its optimum point; I considered constant wind to simplify...

Re: Tip Speed Ratio

Dear Dr Jonkman Thanks a million for your replying. I am using 5MW WT model embedded in FASTV8 and I have not found the term "Trimcase"; On the other hand, my aim is not to make linearization. I provide generator and controller using simulink, and the only problem is that I cannot reach TS...

Tip Speed Ratio

Dear All Hi While controlling a wind turbine, individuals consider a control strategy according to which they can achieve maximum power captured by that, so-called Maximum Power Point Tracking at optimum point for TSR and, in turn, Cp, but my purpose is to study the response of the system in all reg...

Re: 2.5 MW WT

Dear Jonkman
Hi
In order for the wind turbine to be scaled down or up, which parameters (how and from which documents) should be manipulated?

2.5 MW WT

Dear all Hi I'm going to make a Simulink model of 2.5 MW wind turbine. I wonder whether I can use 1.5 MW or 5 MW based one. Actually I mean is it possible for 1.5 MW WT to be changed into 2.5 MW or should I change 5 MW WT into 1.5 one ? I have real data extracted from a 2.5-2.6 MW wind turbine, and ...

Re: Cp (power coefficient) of WindPact 1.5 Mw turbine

Thanks dear

you are trust, but -on the other hand- any kind of winds includes turbulence and transient like what I attached here:
My problem is mainly about the region I point with red color.

Re: Cp (power coefficient) of WindPact 1.5 Mw turbine

Dear Dr.Jonkman Hello I have tried for 1.5 MW, but I found the parameters a little different: at wind speed = 6 m/s and fulfilling maximum power point tracking// Rotor speed = 1.446 rad/s Cp = 0.625 instead of 0.5 TSR = 8.435 instead of 7 beta = 0; What's the problem? Do you think it is unreasonable...

Re: Generator modeling

Dear Jonkman Hello I used the model like that of your publication to provide wind turbine model based on DFIG. The model I made is not exactly this model. Actually I use the one which is provide by Matlab (Phasor type), but I converted it from Wind Farm to a single Wind Turbine changing some coeffic...
