Power factor control mechanism play critical and important role to determine the ability and effectiveness of the operation of doubly-fed induction machines in wind generators and industrial applications. This work presents a vector control (VC) of an emerging brushless doubly-fed reluctance (BDFRG) technology for large wind turbine and industrial applications. The BDFRG has been receiving increasing attention due to its low operation and maintenance costs afforded by the use of partially-rated power electronics, and the high reliability of brushless assembly, while offering performance competitive to its traditional slip-ring counterpart, the doubly-fed induction generator (DFIG). A robust VC strategy has been developed for a custom-designed BDFRG fed from a conventional ‘back-to-back’ IGBT converter. Simulation studies and experimental verification has validated the algorithm under optimum power factor control (OPFC) conditions which allow the improved efficiency of the generator-converter set and the entire wind energy conversion systems (WECS).
