Design and Research of Brushless Doubly Fed Generator with Concentric Winding with Symmetric Arch Distribution Structure

为了克服传统无刷双馈电机谐波磁动势过大,导体利用率低等缺点,引入了转子绕组呈弓形规律对称分布的同心式转子绕组线圈结构。详细分析了这种转子结构的设计方法和原理,并利用Ansoft软件对转子绕组呈弓形规律对称分布的同心式转子绕组线圈结构的无刷双馈发电机进行稳态仿真研究。以一台2 kW样机为例,分析说明无刷双馈电机的稳态电磁性能。

To overcome the defects of low conductor availability ratio and high harmonic content,the concentric winding with symmetric arch distribution structure was introduced to the design of wound rotor. The design method and theory have been given out. And the electromagnetic characteristics of brushless doubly-fed induction generator（ BDFIG） has been researched by the application of Ansoft simulation. At the end,the experimental results of a 2 kW BDFIG was shown.
