Abstract

The Brushless Doubly Fed Machine (BDFM) with high reliability and robust structure demonstrates commercial and technical advantages both as a generator and motor for variable speed applications. As a generator it is particularly attractive to be used in offshore wind turbines where reliability improvement and maintenance cost reduction are the key factors in market growth. As a motor it may be utilized for adjustable speed drives. In this study, a continuous wavelet transform (CWT) technique using a wavelet-based adoptive filter has been proposed for the BDFM fault detection as a generator operating in a wind turbine. Three different generator-typed faults namely rotor torque perturbation, rotor broken bar and grid overvoltage faults have been considered to assess the practicality of the proposed technique. The study has been performed on a D400 250kW BDFM.
