Doubly-fed induction generator control for variable-speed wind power generation system

Abstract

This paper presents control of doubly fed induction generator for variable speed wind power generation. The control scheme uses stator flux-oriented control for the rotor side converter and grid voltage vector control for the grid side converter. A complete simulation model is developed for the control of the active and reactive powers of the doubly fed generator under variable speed operation. Several studies are performed to test its operation under different wind conditions. A laboratory test setup consisting of a wound rotor induction generator by a variable speed dc motor is used to validate the software simulations.
