Enhancement of transient stability of DFIG wind turbine using active disturbance rejection controller

This paper presents an active disturbance rejection (ADR) controller for the enhancement of transient stability of doubly fed induction generators (DFIGs). In real time estimation and mitigation of the total effect of various uncertainties, ADR controller is particularly effective against a wide range of parameter variations, model uncertainties, and large disturbances. The performance of the designed controller is demonstrated by large-disturbance simulations on a test system. The controller successfully limits the oscillations, the peak value of the rotor current, and the dc-link voltage fluctuations and thus enhances transient stability of the DFIG wind turbine.
