wind turbine direct driven a pmsg

I'm doing a project about wind turbine direct driven a pmsg, and i want to ask you how to connect the rotor speed in the pmsg block (rad/s) to the generator speed (pu) in the ind turbine block in simulink. please if anyone can help by explaining to m how or sharing with me a model or a simulation a thesis anything i would be grateful thank you

Hi, you should change the rotor speed output signal from PMSG block in rad/s to pu by deviding the rotor speed (rad/s) by the base value of electrical angular velocity, wr/w_base.

How can we calculate base value of rotor speed?
