不使用定速齿轮箱的连续变速风力涡轮机 (CVSWT) 仍然是现代风力发电行业的可行选择。与标准风力涡轮机的特定齿轮比相比，CVSWT 具有无限数量的传动比。这种传输灵活性使发电机能够保持恒定的速度，无论风速如何高度湍流。近年来，由于对可再生能源的高需求，CVSWT 的发展取得了长足的进步。因此，本文旨在对 CVSWT 进行系统综述，包括机械型、液压型和液压机械型 CVSWT。描述并分析了其工作原理、设计拓扑和基本特征。还讨论了CVSWT的比较和新趋势，表明CVSWT在风电行业应用的可行性以及在兆瓦级CVSWT中使用流体粘性传输的巨大潜力。
Continuously variable speed wind turbines (CVSWTs) without using fixed speed gearboxes continue being as viable options for modern wind power industry. CVSWTs have an infinite number of transmission ratios in contrast to specific gear ratios of a standard wind turbine. This transmission flexibility allows the generator to maintain a constant speed regardless of highly turbulent wind speeds. The development of CVSWTs has made great progress in recent years due to the high demand for renewable energy sources. Therefore, this paper serves to provide a systematic review of the CVSWTs including mechanical, hydraulic and hydro-mechanical type CVSWTs. The operating principles, design topologies and basic characteristics are described and analyzed. The comparisons and new trends of the CVSWTs are also discussed, which indicate the feasibility of applying CVSWTs in wind power industry and the high potential of using hydro-viscous transmission in megawatt CVSWTs.
