feedback linearization method of the present invention is based on doubly-fed induction generator control device as More particularly, the doubly-fed induction generator, but opposite-phase component and a normal component of the rotor current classified into d- and q- axis shaft for each conduct a control, control to linearize the reverse phase component and the top component having a non-linear characteristic by instantaneous power failure conditions, such as the unbalanced voltage in the DC bus voltage to improve the control and output power control relates to a LVRT (Low Voltage Ride-Through) doubly-fed induction generator control apparatus that can implement the functions. To this end the invention is characterized in that: in the doubly-fed induction generators current control device controlled by a power conversion device composed of a generator-side converter for AC-DC conversion is responsible for system-side converter and a DC-AC conversion function that is responsible for function, obtain a doubly-fed induction generator stator voltage and current of the rotor voltage and current and the stator flux and rotor flux measurements separated by a reverse phase signal component and the top component, for each of the opposite-phase component and a normal component of the rotor current d -axis current, and classified by the classification rotor, and q- axis currents to the four current signals, and then, classifying the rotor current signal using the four times normal components of the electronic controller and the current controller is the reverse-phase component measurements control, but, reversed-phase component and the top component controllers each controller using the doubly-fed induction feedback linearization method characterized in that it performs a linearized current output control using the feedback linearization method for d- and q- axis current axis current provides a generator control unit. ; 展开▼
