Brushless doubly fed induction machine (BDFIM) which is able to operate in both induction mode and synchronous mode, has received increasing attention of researchers, in the last three decades. It could be considered as an emerging competitor for older structures, due to the substantial features such as brushless structure and requiring a fractionally rated frequency converter. The iron loss which constitutes a significant portion of total power losses is higher in BDFIM in contrast with standard induction machine. Even though it is essential to consider the iron loss effect on dynamic behavior of BDFIM, there is still no comprehensive study in the literature. The aim of this paper is to propose a dynamic model of BFIM in general reference frame in which the iron loss is taken into account. This model which is credible for all BDFIM operation modes including synchronous one, facilitates the performance analysis of BDFIM and implementation of the various control techniques. The supplementary simulations and experiments confirm that the proposed model is an appropriate candidate for BDFIM drives. Because of the complex structure of BDFIM, determination of the iron loss isn't straightforward. In this paper, a practical approach is introduced to calculate the iron loss of BDFIM in terms of frequency variations. The experimental data derived from a D132s prototype BDFIM is then compared with the calculated data from the finite element analysis (FEA).

考虑铁损的无刷双馈感应电机建模及动态性能分析

在过去的三年中，能够在感应模式和同步模式下运行的无刷双馈感应电机 (BDFIM) 越来越受到研究人员的关注。由于具有无刷结构和需要小数额定频率转换器等重要特性，它可以被视为旧结构的新兴竞争者。与标准感应电机相比，BDFIM 中占总功率损耗很大一部分的铁损更高。尽管必须考虑铁损对 BDFIM 动态行为的影响，但文献中仍然没有全面的研究。本文的目的是在考虑铁损的一般参考系中提出 BFIM 的动态模型。该模型适用于所有 BDFIM 操作模式，包括同步操作模式，有助于 BDFIM 的性能分析和各种控制技术的实现。补充模拟和实验证实，所提出的模型是 BDFIM 驱动器的合适候选者。由于 BDFIM 的结构复杂，铁损的确定并不简单。在本文中，介绍了一种根据频率变化计算 BDFIM 铁损的实用方法。然后将来自 D132s 原型 BDFIM 的实验数据与有限元分析 (FEA) 的计算数据进行比较。补充模拟和实验证实，所提出的模型是 BDFIM 驱动器的合适候选者。由于 BDFIM 的结构复杂，铁损的确定并不简单。在本文中，介绍了一种根据频率变化计算 BDFIM 铁损的实用方法。然后将来自 D132s 原型 BDFIM 的实验数据与有限元分析 (FEA) 的计算数据进行比较。补充模拟和实验证实，所提出的模型是 BDFIM 驱动器的合适候选者。由于 BDFIM 的结构复杂，铁损的确定并不简单。在本文中，介绍了一种根据频率变化计算 BDFIM 铁损的实用方法。然后将来自 D132s 原型 BDFIM 的实验数据与有限元分析 (FEA) 的计算数据进行比较。
