wind turbine block model

In the wind turbine block, a per unit gain is added to the generator speed and to Pm_pu.Could anyone tell me where these values came from, please?

When I look at https://www.mathworks.com/help/physmod/sps/powersys/ref/windturbine.html I would suspect it is normalized efficiency.

[M. A.hsh]

which value of them do you mean ?

[Walter Roberson]

If you are talking about the gain input then it would probably be something that was measured, or was estimated using historical analysis of generator systems.
