The Research of Stand-alone Power Generation With a Novel Wounded Rotor BDFM

Abstract

Brushless doubly-fed machine is a recently developed new-type motor which have a very wide application in VSCF generation system, This paper here intuduce a new-type BDFM used in stand-alone power generation condition which is much flexibler and effective in reducing the harmonic content. The structure and the principle of tooth harmonics wounded rotor BDFM are analysised,also it discusses the unique structure of its control system as stand-alone power generration.To meet the power winding voltage amplitude and frequency ,We discuss the theory and the control strategy of the BDFM generation by power winding voltage amplitude and frequency of closed-loop. And We simulate some condituions of the stand-alone power generation such as rotor speed and load mutation.
