Active disturbance rejection control for stand-alone doubly fed induction generator

Abstract

In this paper, a controller design method is proposed for stand-alone doubly fed induction generator (DFIG). This method is based on forced stator-voltage-oriented vector control principle and active disturbance rejection control (ADRC) approach. Specifically, the forced stator-voltage-oriented vector control principle is used to simplify the mathematics model of stand-alone DFIG and guarantee constant frequency. ADRC approach is used to obtain the constant amplitude of the stator voltage with the variable load. The proposed strategy has a good transient at the start-up and the load changes condition. Simulation results are given to illustrate the efficacy of the proposed method.
