Difference between real time windturbine and wind tunnel CF

Wind & Water General

I’m doing wind turbine analysis on NREL Phase VI turbine using ANSYS Fluent. So it is based on wind tunnel experiment inwhich blade RPM is fixed. But what about real case, in which rotation of the blade depend on the incoming velocity. It cant generate a fixed RPM. I understood gears might be used to control the rpm. Other than ABL, how turbine modelled with fixed RPM can be used to model real time turbine

Dear IjazFazil.SyedAhmedKabir,

I’m not really sure I understand your question, but basically, if the load on the generator doesn’t match the aerodynamically applied torque, the rotor will accelerate or decelerate accordingly.

Best regards,
