Abstract

A methodology to control a Doubly-Fed Induction Generator (DFIG) in zone III without a pitch controller is described. In zone III, the mechanical power harvested through the wind kinetic energy exceeds the rated generator power. Thus, when operating in this zone, the control objective is to keep the generator’s rated power constant. The classical asynchronous machine model in per unit is adapted to satisfy generator operation, power delivered to the grid at the stator winding while preserving the Port-Controlled Hamiltonian (PCH) structure. A control law is synthesized using energy-shaping control by varying the rotor angular velocity reference according to zone III demands. A series of simulations keeping the pitch angle constant are presented to show the effectiveness of the proposed methodology.
