Abstract—An integral sliding-mode direct torque control(ISM-DTC)scheme with space-vector modulation for wind-energycon-version systems based on doubly-fed induction generators(DFIGs) underun balanced grid voltage is proposed.

Abstract— This paper introduces an advanced monitoring and diagnosis system for the detection of incipient electrical faults in doubly fed induction generators used in wind turbines. In this application, the rotor is supplied by a static converter
