Re: Pitch and Torque Cntrl (Region 3)

Hello Jason, I checked Krogmann 15/50 deosn't have region 2.5 (it has four regions 1, 2, 3 ,4). but it has a torque controller. Can you tell me how to apply Wind as Input signal in FAST7 to check Wind turbine Performance(as i have my own wind calculation .wnd file). I tried with Test01_SIG.mdl {Sinc...

Re: What's the exact meaning of HubIner?

Dear Jason, How is Rotor inertia calculated through .fsm file? I have calculated my Rotor inertia = Hub inertia + 3*Blade inertia through this formula i calculated my Rotor inertia = 5229.34 kgm2. But my rotor inertia calculated through FAST .fsm file is 5861.016. Even though Rotor blade mass is cal...

Re: Pitch and Torque Cntrl (Region 3)

Hello jason, Thank you for your response. Sorry you misunderstood, I am not reporting Omega1 and Omega2 values, just describing that Omega1 and Omega2 are where region 21/2 start and end. In my first Post on this page you asked what Omga1 and Omega2 are? My Question still remains, Omega1 and Omega2 ...

Re: Pitch and Torque Cntrl (Region 3)

Dear jason, Thank you for your response. Generator Torque calculated in my case as (GenTq = Rotor Torque/Gearbox ratio), here Rotor Torque = 7.3477kNm and Gearbox ratio = 23.23. So my GenTq = 316.5Nm. And Maximum Generator Power obtains at toruqe 318.31Nm. So i assume Rated Torque to be 318.31Nm. Th...

Re: How are torsional spring and torsional damper calculated?

Dear Dr. Jonkman

Can you please provide the equations to calculate DTTorSpr & DTTorDmp. I used above equations to calculate k or DTTorSpr for test01 with same d1,d2,l1 and l2, i got answer DTTorSpr = 3.0738e+03. Above equation seems wrong.
