Performance Analysis of Doubly Excited Brushless Reluctance Machine Used in Wind Power Generation System

The doubly excited brushless reluctance machine (DEBRM) is a new type of reluctance machine and is attractive for variable-speed constant-frequency wind power generation systems. The DEBRM system features not only simplicity, robustness and reliability of the reluctance or cage-rotor inductance machines, but a much smaller power electronic converter, compared to a conventional AC induction machine. This paper is intended to present a performance analysis of the DEBRM using 2D transient finite element analysis model. The magnetic fields and torque characteristics of the DEBRM are investigated. The results are used to reveal that the DEBRM is attractive for wind power generation system.
