摘要

无刷双馈电机(BDFM)以其结构可靠、励磁调节灵活等优点，广泛应用于风力发电、液压发电、船舶轴系等变速恒频发电领域。提出了一种基于双面变频(DSVF)的无刷双馈发电机(BDFG)系统，并给出了具体的控制策略。与传统的无刷双馈发电机系统相比，该系统具有拓扑简单、动态响应好、鲁棒性强等优点。此外，BDFM的功率绕组频率和控制绕组频率可灵活调节。最后，在一台30kw的BDFM样机上进行了实验，验证了所提出的系统拓扑和控制策略的可行性和可靠性。

Design and Control of the Double Side Variable Frequency Based Brushless Doubly-Fed Generator System

Brushless doubly-fed machine (BDFM) is widely used in wind power, hydraulic power, marine shaft and other variable-speed constant-frequency power generation fields due to its reliable structure and flexible excitation regulation. This paper presents a double side variable frequency (DSVF) based brushless doubly-fed generator (BDFG) system with specific control strategy. Compared with the traditional brushless doubly-fed generator system, this system has the advantages of simple topology, good dynamic response and strong robustness. Moreover, the power winding frequency and control winding frequency of the BDFM are flexibly adjustable. Finally, experimental results from a 30 kW BDFM prototype verify the feasibility and reliability of the proposed system topology and control strategy.
