Abstract

Fault tolerance in wind turbines is considered crucial to increase their reliability and availability levels. This paper presents a fault-tolerant direct-drive permanent magnet synchronous generator (PMSG) using new direct control techniques, with the ability to handle power semiconductor open-circuit faults in the full-scale back-to-back converter. The fault-tolerant topology consists of a five-leg converter, with a shared leg connected to a generator phase and to its corresponding grid phase, through a triode for alternating current (TRIAC). The main contribution of this paper consists of the development of an alternative direct torque control and direct power control schemes for both machine-side converter and grid-side converter, respectively. Moreover, a reliable fault diagnostics algorithm without requiring additional sensors is also integrated, providing the information required to instantaneously trigger fault-tolerant remedial strategies. Simulation and experimental results are presented to validate the effectiveness of the proposed fault-tolerant PMSG drive., BIPD/ICI-FE-Santander Universidades - UBI/2016, This work was supported in part by Santander Totta under fellowship BIPD/ICI-FE-Santander Universidades-UBI/2016, in part by the European Regional Development Fund through the Operational Programme for Competitiveness and Internationalization (COMPETE 2020) under Project POCI-01-0145-FEDER-029494, and in part by the National Funds through the FCT—Portuguese Foundation for Science and Technology.

Abstract

This paper presents a fault tolerant control FTC strategy of Permanent Magnet Synchronous Motor PMSM drive. Position sensor fault detection, isolation and reconfiguration are presented for control scheme devoted for PMSM. MRAS estimator and Luenberger observer are used in order to generate residuals for detection the defect, and then the estimator is used to reconfigure the drive and to conserve the performances of system in order to increase the reliability and to ensure the continuity of the process. The validity of the proposed strategy has been verified by the simulation. [ABSTRACT FROM AUTHOR]
