Wind energy is expected to be a major contributor to the global energy supply in the coming decades, and in many areas it is already the cheapest form of electricity generation available. Offshore wind energy is now playing a significant and rapidly increasing role in areas with suitable shallow seas. A further step to floating offshore wind turbines, which are just beginning to be installed commercially, could massively increase the potential offshore wind resource by allowing deeper sea areas to be used.Research over many years has led to the very large, efficient and cost-effective wind turbine designs seen in today's wind farms. Much recent research has focussed on more efficient and cost-effective installation and operation of wind farms. There is serious interest in novel wind farm control strategies which can improve the operation of the wind farm as a whole, rather than just controlling each wind turbine as if it was operating in isolation from its neighbours. One strategy for example, known as 'wake steering', attempts to deflect each turbine's wake away from downstream turbines, allowing increased overall power production, and longer lifetime through reduced fatigue damage.This study will focus on the use of wake steering in a floating offshore wind farm context. More research is required to get a deeper understanding of the wake effects, particularly in wind conditions typical of offshore environments, so that the most effective control strategies can be devised._DNV GL, Durham University_ and _Ocean Flow Energy_ have partnered to apply to this R&D programme in order to investigate the feasibility of this innovative control technology on floating-offshore wind farms. The main objectives of this research proposal include:* increasing confidence in the use of wake steering,* identifying technical challenges and advantages of using wake steering on floating offshore wind farms,* analysing the effects of the use of wake steering using the Starfloat floating platform design as a benchmark,* analysing the effects of the application of wake steering on the economic performance of a floating offshore wind farm.This research will be carried out in cooperation with a US consortium, led by NREL, which has been formed to investigate similar control strategies for fixed offshore wind farms. Sharing of expertise and wind farm data will lead to improved wake modelling techniques which will help bring the technical and economic benefits of wake steering to the growing US and UK offshore wind farm markets.

预计风能将在未来几十年中成为全球能源供应的主要贡献者，在许多地区，它已经是最便宜的发电形式。现在，海上风能在合适的浅海地区起着显着且迅速增加的作用。浮动海上风力涡轮机的又一个步骤，该风力涡轮机刚刚开始商业上安装，可以通过允许使用更深的海上区域来大大增加潜在的海上风能资源。多年来，研究导致了当今风电场中非常大，高效且具有成本效益的风力涡轮机设计。最近的许多研究集中在风电场的更高效和更具成本效益的装置和运行中。人们对新型风电场控制策略非常感兴趣，这些策略可以改善整个风电场的运行，而不仅仅是控制每个风力涡轮机，就好像它与邻居隔离一样。例如，一种称为“唤醒转向”的策略是试图使每台涡轮机从下游涡轮机唤醒的尝试，从而增加了总体功率产生，并且通过减少疲劳损害的寿命更长。这项研究将集中于在浮动越野风场中使用唤醒转向的使用。需要进行更多的研究以更深入地了解尾流效应，尤其是在海上环境的典型风条件下，以便可以设计最有效的控制策略。该研究建议的主要目标包括：*增强对使用唤醒转向的信心，*确定在浮动海上风电场上使用唤醒转向的技术挑战和优势，*分析使用Starfloat浮动平台设计使用唤醒转向的效果由NREL领导的财团是为了调查固定海上风电场的类似控制策略的成立。共享专业知识和风电场数据将导致改进的唤醒建模技术，这将有助于将唤醒转向的技术和经济利益带入不断增长的美国和英国离岸风电场市场。
