Description

新型固定式风能-波浪能集成发电系统A New Fixed Wind Energy-Wave Energy Integrated Power Generation System

技术领域technical field

本发明属于海上可再生能源利用技术领域，尤其涉及了一种风能-波浪能一体的发电系统，以单桩结构为基础将风能和波浪能相结合的集成发电系统。The invention belongs to the technical field of marine renewable energy utilization, and in particular relates to a wind energy-wave energy integrated power generation system, an integrated power generation system combining wind energy and wave energy based on a single pile structure.

背景技术Background technique

风力发电是目前最具可规模化发展前景的可再生能源。海上风电已成为国际风电发展的新方向，备受各国关注。发展海上风能对于我国治理大气雾霾、调整能源结构具有重要意义。我国东部沿海地区海上风能资源较为丰富，5-25米水深、50米高度海上风电开发潜力约为2亿千瓦。海上相对于陆上有更加丰富的风资源且风能质量更好，不受地形的影响。而且海上蕴藏着巨大的波浪能资源，对波浪能的开发利用也是当今的研究热点之一。不仅资源丰富，而且靠近东部沿海经济中心，避免了远距离电力传输的成本，加大海上风能与波浪能的开发，可有效缓解沿海城市及岛屿电力资源供应的难题。Wind power is currently the most promising renewable energy source for large-scale development. Offshore wind power has become a new direction of international wind power development and has attracted the attention of all countries. The development of offshore wind energy is of great significance to my country's control of atmospheric smog and adjustment of energy structure. my country's eastern coastal areas are rich in offshore wind energy resources. The development potential of offshore wind power at a water depth of 5-25 meters and a height of 50 meters is about 200 million kilowatts. Compared with land, there are more abundant wind resources and better wind energy quality at sea, which is not affected by terrain. Moreover, there are huge wave energy resources in the sea, and the development and utilization of wave energy is also one of the current research hotspots. Not only is it rich in resources, but it is also close to the economic center of the eastern coast, avoiding the cost of long-distance power transmission, and increasing the development of offshore wind energy and wave energy can effectively alleviate the problem of power resource supply in coastal cities and islands.

风力发电不仅在全世界而且在我国也是比较成熟，而波浪能发电装置，能量转化效率低，单位发电成本较高，在一定程度上限制了其商业化。由于风能在可利用范围内是连续的，而波浪是周期性的，其产生的电能是不稳定的、不连续的；但在海风的作用下波浪会由随机的湍流变为有规律的脉动流，为实现风能-波浪能的综合利用提供了可能。多能互补的方法是解决海洋可再生能源综合利用的有效途径。Wind power generation is relatively mature not only in the world but also in my country, while wave power generation devices have low energy conversion efficiency and high unit power generation costs, which limit their commercialization to a certain extent. Since wind energy is continuous within the available range, while waves are periodic, the electric energy generated by it is unstable and discontinuous; but under the action of sea wind, the waves will change from random turbulent flow to regular pulsating flow , which provides the possibility to realize the comprehensive utilization of wind energy-wave energy. The method of multi-energy complementarity is an effective way to solve the comprehensive utilization of marine renewable energy.

具体实施方式detailed description

为了加深对本发明的理解，下面结合附图和技术方案，对本发明作进一步说明。In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.

图1和图2出示了本发明一种新型固定式风能-波浪能集成系统的实施方式。Fig. 1 and Fig. 2 show the embodiment of a novel fixed wind energy-wave energy integrated system of the present invention.

如图1所示，水平轴风机1通过塔筒2和单桩基础5和海床相连。波浪能发电装置是摆动式波浪能发电装置，波浪能发电装置设在单桩基础海平面附近，波浪能发电装置与单桩基础通5过铰链1连接到第一紧固装置6上，在第一紧固装置6和单桩基础5之间安装了套筒8，降低波浪能装置对单桩基础5的作用，达到保护单桩基础5的作用。As shown in FIG. 1 , a horizontal axis wind turbine 1 is connected to the seabed through a tower 2 and a monopile foundation 5 .
