Hello guys,
I'm working on a machine now and it's called DFIG (Doubly-fed Induction Generator). It is connected to a power converter on the rotor only. My question is: how are you able in supersynchronous state to have a induction on the rotor.
I know that you have an excitation current on the rotor to have an induction on the stator when you're in sub-synchronous state. So in supersynchronous how are you able to keep the induction on the stator while you're taking power out of the rotor.
Don't know if it's clear for you and sorry for my bad english.
