Dear Sir,
I am an electrical engineer fresher, currently working in a wind power project in Pune.
I want to know about the doubly fed induction generators used these days in wind turbine generators. The principle of working.
Why does it require a.c in its rotor for the excitation purpose unlike normal generators where dc is fed in the rotor for the creation of magnetic field and rotor excitation.
Thanking you in anticipation
Regards
Vivek
