Abstract

Global industrialization, population explosion and the advent of a technology-enabled society have placed dire constraints on energy resources. Furthermore, evident climatic concerns have placed boundaries on deployable energy options, compounding an already regrettable situation. It becomes apparent for modern renewable energy technologies, including wind generators, to possess qualities of robustness, high efficiency, and cost effectiveness. To this end, direct-drive permanent magnet (PM) wind generators, which eliminate the need for gearboxes and improve wind turbine drivetrain reliability, are trending. Though rare-earth PM-based wind generators possess the highly sought qualities of high-power density and high efficiency for direct-drive wind systems, the limited supply chain and expensive pricing of the vital raw materials, as well as existent demagnetization risks, make them unsustainable. This paper is used to provide an overview on alternative and viable non-conventional wind generators based on the so-called non-PM (wound-field) stator-mounted flux modulation machines, with prospects for competing with PM machine variants currently being used in the niche direct-drive wind power generation industry.

非传统，非永磁风力发电机候选

全球工业化、人口爆炸和技术驱动型社会的到来对能源资源构成了严峻的制约。此外，明显的气候问题给可部署的能源选择划定了界限，使本已令人遗憾的情况更加恶化。包括风力发电机在内的现代可再生能源技术显然具有坚固、高效和成本效益的特点。为此，直接驱动永磁(PM)风力发电机是一种趋势，它消除了对齿轮箱的需求，提高了风力涡轮机传动系统的可靠性。虽然稀土永磁风力发电机具有直接驱动风力系统中备受追捧的高功率密度和高效率的品质，但关键原材料有限的供应链和昂贵的定价，以及存在的退磁风险，使其不可持续。本文概述了基于所谓的非PM(绕组场)定子安装磁通调制机的替代和可行的非传统风力发电机，并展望了与目前在利基直接驱动风力发电行业中使用的PM机类型竞争的前景。
