Detailed Design Procedures for PMSG Direct-Driven by Wind Turbines

Abstract

This paper is committed to show a well-ordered system used to design a permanent magnet synchronous generator (PMSG). The fundamental focus of this work is the generators which are in gearless configuration, and in the fragmentary or couple of kilowatts power range. A straight lumped-component based model is introduced, which is utilized for fundamental investigation and design. Later, a proposed comprehensive design strategy—stated with conditions, tables, design limits and practical recommendations—are presented in full details. Likewise, a flowchart is created to be later used as a Matlab M-File code for PMSG design. The outlined strategies are then authenticated through three case studies while being compared to the result from Finite Element Method (FEM) of Maxwell package. The three case studies are firstly, comparing the effectiveness of the procedures with a PMSG presented in literature. Secondly compared to a generator from the market. And finally using the procedure to implement a 1 kw prototype generator and validate the results with it. Such comparisons have validated the proposed procedures as a contributed step-by-step simple and reliable design tool for such cluster of PMSGs.
