CONTROL DEVICE FOR A DOUBLY-FED INDUCTION GENERATOR IN WHICH FEEDBACK LINEARIZATION METHOD IS EMBEDDED

摘要

PURPOSE: A wounded type induction generator control device which uses a feedback linearization method is provided to have a low voltage ride-through function by controlling a normal component and a reverse component in order to be linearized. CONSTITUTION: A measured value which divides stator voltage and current, rotor voltage and current, and stator magnetic flux and rotator magnetic flux into a normal component and a reverse component is obtained. The rotor current is classified as four signals by classifying the normal component and the reverse component as a d-shaft current and a q-shaft current. A normal component controller and a reverse component controller classify and control the four signals of the rotator current by using the measured value. The component controller and the reverse component controller classify control input and output of a linearized current by using a feedback linearization method about the d-shaft current and the q-shaft current.
