SWRT optimal power coefficient

Hello All,

I implemented a 10Kw an hybrid excitation synchronous generator under Simulink, and i want to connect my model to the SWRT turbine. In order to control my wind conversion system in the MPPT zone, i need to know the optimal TSR and the optimal power coefficient. Unfortunatelly, the WT_Pref code is not available any more. I wonder if any one has an idea about these values please?

Dear Amina,

I don’t recall if the power coefficient (Cp) as a function of tip-speed ratio (TSR) has been published for the Small Wind Research Turbine (SWRT). However, you can calculate these with the standalone AeroDyn v15 driver e.g. see: http://forums.nrel.gov/t/effecting-of-turbulence-intensity-on-load-of-wt-blade/1047/13 (more difficult, but allows the rotor to be flexible).

Best regards,

Thank you very much for your help.
