Experimental Validation of a Rotating Power Electronic Brushless Doubly-Fed Induction Generator for Variable-Speed Operation
(English)Manuscript (preprint) (Other academic)
This paper investigates through experiments a differenttopology of a brushless doubly-fed induction generatorwith a rotating power electronic converter: the rotatingpower electronic brushless doubly-fed induction generator (RPEBDFIG),operated with variable speed and torque. The theorybehind the operation of the generator is presented, its dynamicmodel and control aspects are discussed, and closed-loop controlof the generator is implemented and verified through experimentson an 11-kW prototype. The measurement results show stableoperation for variable speed and torque regions. Moreover, itis shown that the integrated rotating exciter is sufficient torecover slip power and deliver to the grid, hence, verifyingsuccessful brushless operation. Besides, it is verified that thegenerator operates well in both regions of operation, i.e., the subsynchronousand super-synchronous modes, and is stable undertorque transients added by the rotating exciter.
