Control of wind power

The paper is concerned with the Wind Energy Converter System applying Doubly Fed Induction Generator. It treats the control of Rotor Side Converter when the stator flux oriented vector control strategy is used. The relations are derived governing the stator and rotor power flow and the electric torque controlled by the d and q component of the rotor supply voltage. The relations are illustrated by characteristics in per unit and their evaluations throw light to the physical background with practical application comments. The description is devised in a comprehensive and concise way.
