Novel Coordinated Converter Control (3C) Strategy for Enhancement of Fault Ride-through Capability of Doubly Fed Induction Generator Wind Farms

Abstract

A novel coordinated converter control strategy is proposed in this article for enhancement of the fault ride-through capability of doubly fed induction generator based wind farms. The proposed coordinated converter control strategy is activated only during the instance of fault clearance in order to achieve rapid restoration of terminal voltage and thereby enhance the post-fault performance capability of wind generators connected to the distribution network. An extensive simulation study is carried out employing PSCAD/EMTDC software (Manitoba, Canada). The simulation results demonstrate the laudable performance of the doubly fed induction generator achieved by employing the coordinated converter control strategy.
