O&M Optimisation Rotor Wind Turbine

项目摘要

The "X-Rotor offshore wind turbine" is a Vertical Axis Wind Turbine (VAWT)/Horizontal Axis Wind Turbine (HAWT) hybrid. The X-rotor concept directly targets cost of energy reduction and addresses scalability of wind turbines through a combination of the following key innovations: 1) Large reductions in the cost of drive-trains through an easily scalable approach to power take-off that does not require a gearbox or a multi-pole generator, whilst still achieving comparable efficiency levels in power conversion. 2) Large reductions in Operation and Maintenance (O&M) costs through no heavy components or machinery being situated at a great height above sea-level, and through general simplification of the turbine. My PhD aims to address the new challenges in operations and maintenance strategies. There are three work packages that aim to conclude the lowest operational cost for each problem. Firstly, the control implementation of utilising the turbine if one of the secondary (HAWT) rotors is not functioning will allow there to still be energy extraction, but is the increased loading on the turbine worth this? Additionally, the maintenance method for the secondary turbines has several options, such as modular rotors which can be maintained onshore, or alternatively more conventional offshore maintenance. And finally, the rotational speed of the secondary rotors is going to be much greater than conventional turbines, hence my investigation into the maintenance method and composition of the blades.

“X转子海上风力涡轮机”是垂直轴风力涡轮机（VAWT）/水平轴风力涡轮机（HAWT）混合动力。X-转子概念直接针对降低能源成本，并通过以下关键创新的组合解决风力涡轮机的可扩展性：1）通过不需要齿轮箱或多极发电机的易于扩展的动力输出方法大幅降低传动系统的成本，同时仍然实现功率转换的可比效率水平。2)通过不将重型部件或机械放置在海平面以上的很高的高度，以及通过涡轮机的总体简化，大大降低了操作和维护（O&M）成本。我的博士学位旨在解决运营和维护策略中的新挑战。有三个工作包，旨在为每个问题得出最低的运营成本。首先，如果次级（HAWT）转子中的一个不起作用，则利用涡轮机的控制实现将允许仍然存在能量提取，但是涡轮机上的增加的负载值得这样做吗？此外，二次涡轮机的维护方法有几种选择，例如可以在陆上维护的模块化转子，或者替代地更传统的海上维护。最后，二次转子的转速将远远大于传统涡轮机，因此我对叶片的维护方法和组成进行了调查。
