Simulation of a site-specific doubly-fed induction generator (DFIG) for wind turbine applications [PDF]
2008 18th International Conference on Electrical Machines, 2008 This paper describes a preliminary study of a 30 kW doubly-fed induction generator (DFIG) used for wind turbine applications. Wind represents a variable-speed intermittent source of energy in nature and can be controlled to be a nearly constant speed but variable-torque input to the wind turbine using blade pitch angle regulation.
