要約(日本語): An H-infinity control scheme is developed to enhance the fault ride-through (FRT) capability of doubly-fed induction generators (DFIGs) based wind turbines (WTs) during transient-state. This technique is chosen because of its capability to synthesize controllers with disturbance attenuation, robust stabilization and closed-loop response. The control function in the vector control of DFIG is performed by PI controllers whose FRT capability is not satisfactory. In this study, these PI controllers are replaced by robust H-infinity controllers in the current regulators of the vector control system. Appropriate controllers are synthesized for the rotor and grid side convertors of the DFIG.
