Fault-Tolerant Back-to-Back Converter for Direct-Drive Permanent Magnet Synchronous Generators Wind Turbines Using Direct Torque and Power Control Techniques

Abstract

Fault-tolerance is considered critical in wind turbines to improve their dependability and availability. This the document has a fault-tolerant permanent magnet with direct drive new direct control synchronous generator PMSM methods capable of handling high-power semiconductors OPEN-CIRCUIT failure in back-to-back transmissions. The faults-tolerance scheme is made up of 5 legs. A converter through an interlinked leg linked to an alternator phase and a converter with a shared leg connected with an alternator phase, a converter through a Triode for Alternating Current to its appropriate grid phase. The creation of DTC and DPC techniques for MSC and GSC is the major contribution of this work. A dependable failure diagnostics algorithm is also implemented, which provides the information needed to instantly activate fault-tolerant remedial techniques without the use of extra sensors. To validate the efficacy of the proposed fault-tolerant PERMANENT MAGNET SYNCHRONOUS GENERATORS drive, simulation and experimental data are provided.
