Application of Brushless Doubly-Fed Machine System in Hydropower Generation

The brushless doubly-fed generator (BDFG) is a kind of novel machine, which can be regarded as a combination of conventional synchronous and asynchronous motors. Due to its absence of brush and slip rings, BDFG has potential in hydropower generation. The paper first evaluates the feasibility of BDFG for hydropower generation system and verify the proposed control strategy, based on a practical application in Daliang hydropower station.
