Description
Technical Field
The invention belongs to the field of ocean renewable energy utilization, and particularly relates to a wave energy-wind energy combined power generation system and method.
Background
In recent years, with the worldwide energy problem and the environmental problem becoming more prominent, the issues of the traditional energy and the new energy are being researched and discussed by the broad universe of scholars and engineers. In order to solve the problems of serious environmental pollution, insufficient utilization rate and the like of the traditional energy, various countries advocate developing new energy and low-carbon power. Among them, offshore wind power is receiving more attention due to its advantages of no pollution, no occupation of cultivated land, abundant reserves, etc.
Offshore wind power is mainly divided into fixed wind power and floating wind power, and with the increase of water depth, the cost of the traditional fixed foundation is too high, so that the offshore wind power can not be applied to the development of deep-sea wind power. Floating wind power is gaining favor from all countries due to its unique advantages in deep sea. The wind power generator is mainly divided into a horizontal axis wind power generator and a vertical axis wind power generator, and most of the wind power generators are horizontal axis wind power generators at present. With the continuous development of wind power technology, vertical axis wind power generators are receiving more and more attention. The vertical axis wind turbine mainly has the following advantages: the vertical axis wind turbine has lighter overall weight, can reduce the load on an ocean platform, has low requirement on the sensitivity of the vertical axis wind turbine to the wind direction, and can further reduce the mass of the vertical axis wind turbine without a yaw system. Particularly in the field of deep-sea floating type wind turbines, the gravity center of the vertical-axis wind turbine is low, and the combination of the vertical-axis wind turbine and the floating foundation can effectively reduce the motion of the platform, so that the wind turbine can generate power more stably. Researchers propose an offshore floating type fan system based on a vertical axis wind turbine, but the common characteristics of all schemes are single-rotor design, and the fan is easy to generate overlarge bending moment in one-way operation under the action of wind force, so that great challenges are provided for an anchoring system. The reserve of wave energy resources in areas with rich wind energy resources is often considerable, and the wave energy power generation device is simple, mechanical devices are not easy to corrode by seawater, and adaptability is strong. However, the wave energy power generation device has limited commercialization and scale-up to some extent due to high construction cost, low energy conversion rate, and the like.

And the wave energy power generation device has simple structure and lower cost.
7) The wind and the wave are strong or weak at the same time, and the excessive wind and wave can easily cause the poor wind and wave resistance of the energy conversion device, the very unstable platform and the large wind quantity for the independent wave energy and wind energy obtaining mode, destructive to wave energy collection, large waves, and destructive to wind energy collection, because energy that is not collected greatly affects platform stability and creates energy losses, in which case, when wind energy is collected, if wave energy is collected at the same time, the influence on the stability of the platform, which is greater because the wave energy is not collected, can be reduced, in this case, not only is energy collected, converted and transmitted simultaneously by the same platform, the energy and facilities are fully and reasonably used, and on the other hand, the influence of the energy which is not collected on the stability of the platform when the energy and the facilities are collected independently and the wind waves are large can be reduced.
