Optimization and comparison of flux-concentrating Nd-Fe-B generator considering variable power factor and wind conditions for a 6MW offshore wind turbine / Nurul Azim, Bhuiyan

53rd International Universities Power Engineering Conference (UPEC 2018)

Swansea University Author: Nurul Azim, Bhuiyan

Abstract

A large proportion of offshore wind turbine designs are now based on directly driven permanent magnet synchronous generators using rare earth materials. During last few years, the price of Nd-Fe-B has increased and fluctuated significantly. The large price fluctuations encourage us to look at flux-c...
