Fault Detection in the NPC Converter of a DFIG-based Wind Generation System with Field-Oriented Control

Resumen: This work presents a fault detection scheme for a wind generation system, which is composed of a doubly-fed induction generator (DFIG) interconnected to the electric grid using a neutral-point-clamped (NPC) power electronic converter in a back-to-back (BTB) configuration. The converter operates in a closed-loop with field-oriented control (FOC). The type of faults that are analyzed is open-circuit in the switching devices. A fault detection strategy is proposed based on the discrete wavelet transform (DWT) with the Haar wavelet.
