[0002] At present, although both wind power generation and solar power generation technologies are becoming mature, solar power is intermittent during the day and night, and wind power is also volatile, and both depend on weather conditions. Therefore, the development of wind-solar complementary power generation systems can give full play to the advantages of both, and well connect the complementarity in time and space, which will have broad application prospects in distributed power generation scenarios.

[0003] At present, the application of wind-solar complementary systems has not yet been widely popularized.

[0038] Furthermore, although the terms used in the present invention are selected from well-known and commonly used terms, some terms mentioned in the present invention specification may be selected by the applicant at his or her discretion, and their detailed meanings are explained in the relevant parts of the description of this document.

[0039] Furthermore, it is required that the present invention be understood not only by the actual terms used but also by the meanings connoted by each term.

[0040] like Figures 1 to 5 As shown, the present invention provides a wind-solar complementary power generation system with a tower structure, and the power generation system includes: a tower 100, a wind turbine 200, a photovoltaic module 300 and a wind-solar complementary controller. Among them, the tower 100 is used to carry and fix the entire wind-solar complementary power generation system. The wind turbine 200 is fixedly installed on the top of the tower 100. The photovoltaic module 300 is installed on the side of the tower 100. The wind-solar complementary controller is electrically connected to the wind turbine 200 and the photovoltaic module 300, and is used to simultaneously control the wind turbine 200 and the photovoltaic module 300, and allocate the combined wind turbine 200 and the photovoltaic module 300 to supply power to the load according to the different changes in wind force and sunshine under climatic conditions.

[0041] The wind turbine 200 is an electric device that converts wind energy into mechanical work, which drives the rotor to rotate and finally outputs alternating current. The photovoltaic module 300 can convert solar radiation energy into electrical energy.

[0042] The tower 100 has a certain height and is erected on the ground to fix and support the wind turbine 200 and the photovoltaic module 300. The height of the tower 100 can be freely selected according to different environments. As a preferred embodiment, the height of the tower 100 used can be preferably 10m. The side of the tower 100 where the photovoltaic module 300 is arranged is preferably the sunny side to obtain a higher photovoltaic power generation efficiency.

[0043] The wind-solar complementary power generation system with a tower structure in this embodiment is combined with a wind turbine 200 and a photovoltaic module 300 in the form of a tower 100, which improves the photovoltaic utilization rate per unit area and realizes the complementarity of wind power and light. The system not only has high power supply stability and reliability, but also has a much lower cost than the long-distance small-load power supply of the power grid, and its use is not restricted by geographical location. In addition, the wind-solar complementary power generation system uses wind energy and solar energy to generate electricity in a complementary manner, which saves conventional energy, reduces environmental pollution, and meets the requirements of carbon saving, emission reduction and environmental protection.

[0044] like Figures 1 to 5 As shown, as a preferred embodiment of the wind-solar hybrid power generation system with a tower structure of the present invention, the photovoltaic assembly 300 includes at least two solar panels.

[0045] Solar panels are a common photovoltaic assembly 300. Providing at least two solar panels can improve the utilization rate of the longitudinal space on the side of the tower 100, increase the utilization area of ​​the photovoltaic panels, and thus improve the efficiency of photovoltaic power generation. For example, there are three solar panels in this embodiment, which are sequentially arranged on the side of the tower 100 from top to bottom.

[0046] like Figures 1 to 5 As shown, as a preferred embodiment of the wind-solar hybrid power generation system with a tower structure of the present invention, the solar panel is obliquely installed on the side of the tower 100 through a bracket 310.

[0047] In the above embodiment, a bracket 310 is installed on the lower side of each solar panel. Fixing the solar panel to the side of the tower 100 by the bracket 310 can enhance the reliability of the solar panel installation. Since the solar panel is tilted by the bracket 310, the incident angle of sunlight can be increased, thereby improving the efficiency of photovoltaic power generation; and since the solar panel is tilted by the bracket 310, the sunlight received by the solar panel located at the bottom will not be blocked by the solar panel at the upper part, thereby ensuring the light receiving area of ​​each solar panel, and the angle of illumination is optimal, thereby improving the efficiency of photovoltaic power generation.

[0048] like Figures 1 to 5 As shown, as a preferred embodiment of the wind-solar hybrid power generation system with a tower structure of the present invention, the bracket 310 is a rectangular frame, and each of the rectangular frames is installed on the lower side of the corresponding solar panel to fix the solar panel.

[0049] The rectangular frame is used as the bracket 310 for fixing the solar panel, which is easy to process and has a good fixing effect. The rectangular frame can be made of square steel pipe.

[0050] like Figures 1 to 5 As shown, as a preferred embodiment of the wind-solar hybrid power generation system with a tower structure of the present invention, the side of the tower 100 on which the solar panels are mounted has an inclination angle, and the inclination angle makes the solar panels not block each other under light.

[0051] The inclination angle of the side of the tower 100 on which the solar panel is installed, combined with the tilted setting of the solar panel, further ensures that the sunlight received by the solar panel located at the bottom will not be blocked by the solar panel at the top, thereby ensuring the light-receiving area of ​​each solar panel and the optimal setting angle, further improving the efficiency of photovoltaic power generation.

[0052] For example, the tower 100 may be configured such that the side with the solar panel mounted thereon has a greater inclination angle than the side without the solar panel mounted thereon.

[0053] like Figures 1 to 4 As shown, as a preferred embodiment of the wind-solar hybrid power generation system with a tower structure of the present invention, the wind turbine 200 is an H-type vertical axis wind turbine.

[0054] The wind turbine 200 is a heat energy utilizing engine that uses the sun as a heat source and the atmosphere as a working medium. The vertical axis wind turbine does not need to face the wind when the wind direction changes, which is a major advantage over the horizontal axis wind turbine. It not only simplifies the structural design, but also reduces the gyroscopic force of the wind rotor facing the wind. The H-type vertical axis wind turbine adopts the principle of aerodynamics. For the wind tunnel simulation of the vertical axis rotation, the blade 210 is selected in the shape of an airplane wing. When the wind rotor rotates, it will not be affected by deformation and change in efficiency.

[0055] like Figures 1 to 4 As shown, as a preferred embodiment of the wind-solar complementary power generation system with a tower structure of the present invention, the H-type vertical axis wind turbine includes a plurality of H-shaped blades 210 that are relatively cross-arranged, and a central axis 220 is provided in the middle of the H-type vertical axis wind turbine, which is fixed to the top of the tower 100 through the central axis 220.

[0056] The H-shaped vertical axis wind turbine in the above embodiment includes five (or three) H-shaped blades 210 that are relatively cross-arranged.

[0057] The H-type vertical axis wind turbine 200 of the above structure utilizes wind power to drive the blades 210 to rotate, converting wind energy into mechanical energy to promote the wind turbine 200 to generate electricity.

[0058] As a preferred embodiment of the wind-solar hybrid power generation system with a tower structure of the present invention, the wind-solar hybrid controller can control the power supply of the wind generator 200 and the photovoltaic module 300 respectively according to the actual power generation power of the wind generator 200 and the photovoltaic module 300.

[0059] The wind-solar hybrid controller is an intelligent controller that integrates wind and solar energy control. Since wind and solar resources are distributed differently in different regions, seasons, and weather conditions, the use of a single energy source may cause problems such as insufficient or unbalanced power supply. In addition, the one-time investment in wind power generation is low, while the maintenance of photovoltaic solar power generation systems is low. For remote or inconvenient areas, system maintenance is inconvenient.

[0060] Therefore, the setting of the wind-solar complementary controller can control the wind turbine 200 and the photovoltaic module 300 at the same time. According to the different changes in wind and sunshine in climatic conditions, the wind turbine 200 can supply power to the load alone when the wind is strong, or the photovoltaic module 300 can supply power to the load alone when the sunshine is good, or they can jointly supply power to the load when the wind and sunshine are both good, which greatly improves the power generation efficiency and makes the power supply more reliable and stable.

[0061] As a preferred implementation of the wind-solar hybrid power generation system with a tower structure according to the present invention, the power generation system is equipped with a storage battery.

[0062] The electric energy obtained by the wind turbine 200 and the photovoltaic assembly 300 can be stored in the battery. For example, when the sunlight and wind energy resources are sufficient, the excess electricity generated by the power generation system is stored.

[0063] As a preferred embodiment of the wind-solar hybrid power generation system with a tower structure of the present invention, the wind-solar hybrid controller can store the electric energy obtained by the wind turbine 200 and the photovoltaic module 300 in a storage battery.

[0064] Through the control of the wind-solar hybrid controller, the function of storing the electric energy obtained by the wind turbine 200 and the photovoltaic module 300 in the battery is realized.

[0065] The wind-solar complementary power generation system with a tower structure of the present invention improves the utilization rate of the longitudinal space by installing the photovoltaic panels on the tower 100 layer by layer, thereby increasing the utilization area of ​​the photovoltaic panels. The wind-solar complementary power generation system with a tower structure combines the wind turbine 200 and the photovoltaic solar panel in the form of a tower 100, thereby improving the photovoltaic utilization rate per unit area and realizing the complementarity of wind power and light. By increasing the side inclination angle of the tower 100, the photovoltaic panels on each layer do not block each other, thereby improving the utilization rate of the photovoltaic panels on each layer. The system not only has high power supply stability and reliability, but also because the cost of the system is much lower than the long-distance small-load power supply of the power grid, its use is not restricted by geographical location. In addition, the wind-solar complementary power generation system uses wind energy and solar energy to generate electricity in a complementary manner, saves conventional energy, reduces environmental pollution, and meets the requirements of carbon saving, emission reduction and environmental protection.

Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
