Ensuring Fault Ride Through for Wind Turbines with Doubly Fed Induction Generator: a Model Predictive Control Approach

This paper proposes a novel control strategy, based on Model Predictive Control (MPC), which ensures Fault Ride Through (FRT) for wind turbines with Doubly Fed Induction Generators (DFIGs). During large voltage dips, large currents are induced in the rotor that can destroy the rotor converter. The common approach used to protect the rotor converter is to disable the converter and to dissipate the rotor power via a crowbar circuit. This approach …
