Abstract

This paper presents the operational principles, design and transient analysis of a new three-phase 12/14-pole doubly salient electrical magnet (DSEM) generator for its application in direct-driven wind power generation. Design equations, finite element and dynamic analysis of the new generator are described. The 12/14-pole DSEM generator with constant self-inductance has lower voltage ripple compared with the conventional DSEM generator. The evaluation of the system performances is conducted by computer simulation.
