fi.floris.turbine_map equivalent in v3

[vijay092]

Looks like fi.floris.turbine_map has been removed from FLORIS 3.0. Is there an equivalent in the new version?
I would like to perform the following operation:

for coord, turbine in fi.floris.farm.turbine_map.items:
        ct.append(turbine.Ct)
        ai.append(turbine.aI)
        ave_vel.append(turbine.average_velocity)

Hi @vijay092

In v3, we've moved from having a instance of the Turbine class for each turbine in the wind plant to having a turbine definition and using that along with the conditions at the turbine to calculate the performance quantities. You can use the functions in src/floris/simulation/turbine.py for power, Ct, axial induction, and average velocity. Moving these out of the turbine class allows for a much more efficient computation.

We don't have a formal example for this yet, but a pattern is included in the regression tests:
https://github.com/NREL/floris/blob/v3/tests/reg_tests/jensen_jimenez_regression_test.py#L111

Does this answer your question?

Great, thanks so much for the clarification!

No problem, thank you for using v3! Please keep in touch if you have other questions or feedback.

In the current implementation, is it possible for every turbine in the farm to have different parameters?

[bayc]

I am currently implementing that and will have it merged soon! By different parameters, you mean hub height, rotor diameter, Cp/Ct table, those kind of parameters, right?

[vijay092]

Hey @bayc! Yes, that is correct. Looking forward to it :)
