modelAsynchron_dfig
Doubly fed induction generator, 3-phase dq0
Extends from AC3ph.Machines.Partials.AsynchronBase (Asynchronous machine base, 3-phase dq0).
Information
A doubly fed induction generator is has a second feed to the rotor windings (term_r). A wide range of rotor speeds can be achieved by controlling the AC voltage of term_r. Doubly fed induction generators are popular for wind turbines.
For more information see Partials.AsynchronBase.
