综述了垂直轴风力发电机（VAWTs）发展中存在的技术挑战及其潜在解决方案。在过去的十年中，VAWT由于其固有的特性，如全向特性，简化的叶片几何形状，产生的噪声较低，以及地面发电机易于接近，受到研究人员和科学家越来越多的关注。然而，它们的主要缺点，如较低的功率系数，自启动能力差，以及由于循环空气动力学负载引起的疲劳问题，使它们比水平轴风力涡轮机（HAWT）更缺乏竞争力。本文将分享一个新的角度对最先进的垂直轴风力发电机的状态，探索新的机会和可能性，其商业可行性。对垂直轴风力发电机和水平轴风力发电机的气动性能、效率、风电场功率密度和自起动能力进行了全面的比较。该综述文件的目的是确定风力涡轮机市场中商用VAWT的技术障碍、设计挑战和未来，目前该市场由传统HAWT主导。本文将讨论甚高频风力发电机在未来与高频风力发电机竞争的主要技术障碍。此外，审查将讨论在过去十年中提出的创新技术是否在商业上可行，以克服VAWT的缺点。本文还将探讨通过从陆上安装的涡轮机中吸取的经验教训，VAWT在海上应用中是否更具竞争力。
A review of existing technical challenges and their potential solutions in the development of Vertical Axis Wind Turbines (VAWTs) is presented in the context. Over the last decade, VAWTs have received increasing attention from researchers and scientists due to their inherent features such as omni-directional property, simplification of the blade geometry, lower noise generated, and easy accessibility attributed to the ground-based generators. However, their major drawbacks such as lower power coefficient, poor self-starting capability, and fatigue issues due to cyclic aerodynamics loads, make them less competitive than Horizontal Axis Wind Turbines (HAWTs). This paper will share a new perspective on the state of the art VAWTs to explore the new opportunity and possibility for their commercial viability. A comprehensive comparison was performed between VAWTs and HAWTs focused in different sections on their aerodynamic performance, efficiency, power density in a wind farm, and self-starting ability. The objective of the review paper is to identify technical barriers, design challenges and the future of commercial VAWTs in the wind turbine market, currently dominated by conventional HAWTs. The paper will address what the major technical barriers for VAWTs to compete against HAWTs in future. Moreover, the review will discuss if the innovative technologies proposed in the last decade are commercially feasible to overcome drawbacks of VAWTs. The paper will also explore if VAWTs are more competitive in offshore application through the lessons learned from onshore turbines installed.
