A brushless doubly-fed reluctance generator has been seen by research communities as a potential solution
to higher operation and maintenance costs associated with the compromised reliability of brush
compartment of conventional doubly-fed induction generators, while offering comparable performance
and similar cost benefits of using a partially-rated power electronic converter in wind power applications.
A new flux vector oriented encoder-less scheme for speed and inherently decoupled torque and reactive
power control has been proposed and successfully experimentally verified on a small machine prototype
by emulating the typical torque-speed operating characteristics of ordinary horizontal-axis wind turbines.
The obtained test results have clearly indicated the excellent controller response and disturbance
rejection abilities over the entire speed range of interest.
