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.
