Description
技术领域technical field
本发明属于海洋能利用领域，涉及深水风能-波浪能-潮流能综合利用装置，尤其涉及一种基于张力腿平台垂直轴风力机-两向波浪能装置-潮流能装置集成结构。The invention belongs to the field of ocean energy utilization, and relates to a deep-water wind energy-wave energy-tidal energy comprehensive utilization device, in particular to an integrated structure based on a tension leg platform vertical axis wind turbine-two-way wave energy device-tidal energy device.
背景技术Background technique
海上风能、波浪能和潮流能都是清洁可再生的海洋能源，可利用风力发电机将风力能转换成电能，利用波浪发电装置将波浪能转换成电能，利用潮流发电装置将潮流能转换成电能。我国东部沿海的海上可开发风能资源不仅资源潜力巨大，而且开发利用市场条件良好，更靠近中国的经济中心。海上风能开发具有节约宝贵土地资源、风力更稳定、风电机组单机容量更大、年有效利用小时数更高、受噪音标准限制更小、运输条件更为便利等优势。风能丰富水域的波浪能资源和潮流能资源也相对丰富。但由于波浪能发电装置能量转化率较低，单位发电成本较高，一定程度限制了其商业化应用。Offshore wind energy, wave energy and tidal current energy are all clean and renewable marine energy sources. Wind power generators can be used to convert wind power into electrical energy, wave power can be used to convert wave energy into electrical energy, and tidal current power can be used to convert tidal current energy into electrical energy. . The exploitable offshore wind energy resources in the eastern coast of my country not only have huge resource potential, but also have good market conditions for development and utilization, and are closer to China's economic center. Offshore wind energy development has the advantages of saving precious land resources, more stable wind power, larger wind turbine unit capacity, higher annual effective utilization hours, less restricted by noise standards, and more convenient transportation conditions. The wave energy resources and tidal current energy resources in wind energy-rich waters are also relatively abundant. However, due to the low energy conversion rate of wave power generation devices and the high unit power generation cost, its commercial application is limited to a certain extent.
目前，近海风力发电装置的基础主要有单桩式、多桩式、重力式、导管架式、高桩承台式等固定式支撑平台结构，深水浮式海上风力机的研究还处于起步探索阶段，国外已建成了几座代表性浮式海上风力机示范项目，主要结构形式有：Spar式、张力腿式和半潜式等平台系统，其中张力腿式风机平台性价比较高。波浪能发电装置的种类繁多，不拘一格，有点头鸭式、波力发电船式、环礁式、整流器式、海蚌式、软袋式、振荡水柱式、多共振荡水柱式、波流式、摆式、结合防波堤的振荡水柱式、收缩水道式等十余种。At present, the foundations of offshore wind power generation devices mainly include fixed support platform structures such as single pile type, multi-pile type, gravity type, jacket type, and high pile cap type. The research on deep-water floating offshore wind turbines is still in the initial stage of exploration. Several representative floating offshore wind turbine demonstration projects have been built abroad. The main structural forms include: Spar, tension leg and semi-submersible platform systems, among which the tension leg wind turbine platform is more cost-effective. There are many types of wave energy generating devices, eclectic, nodding duck type, wave power generation ship type, atoll type, rectifier type, sea clam type, soft bag type, oscillating water column type, multi-common oscillating water column type, wave current There are more than ten types such as pendulum type, pendulum type, oscillating water column type combined with breakwater, and shrinking channel type.
现有技术的不足是：波浪能发电装置和潮流发电装置的能量转化率较低，单位发电成本较高，且缺少同时利用两向及多向相对运动获取波浪能的发电装置结构系统。目前还非常缺少将垂直轴风力机、多向波浪能发电装置、潮流能发电装置集成为一体的海洋能源综合开发结构系统。The deficiencies of the prior art are: the energy conversion rate of the wave power generation device and the tidal current power generation device is low, the unit power generation cost is high, and there is a lack of a power generation device structural system that simultaneously utilizes two-way and multi-way relative motion to obtain wave energy. At present, there is still a lack of a comprehensive marine energy development structure system that integrates vertical axis wind turbines, multi-directional wave energy generation devices, and tidal current energy generation devices.
