Description

Technical Field

[0001] This invention relates to the field of new energy comprehensive utilization technology, specifically to a vertical wall-type wind and solar co-generation system. Background Technology

[0002] Distributed renewable energy generation is now widely used. Traditional distributed photovoltaic (PV) systems are mostly installed on rooftops, ground supports, or building facades. Ground-mounted PV requires a large amount of independent land, while rooftop PV is limited by building load, sunlight angle, and shading. Facade PV also suffers from low power generation efficiency and high maintenance difficulty. Wind turbines can generate electricity day and night, but if deployed separately, additional towers, independent foundations, and protective areas are required, resulting in high engineering costs. Walls around roads, industrial parks, factories, and residential areas represent existing linear spaces, characterized by their long length, regular boundaries, and natural enclosure. However, current technologies have not fully utilized the energy potential of these spaces. Common wind-solar hybrid systems have many drawbacks: separate base structures occupy a large area and are unsuitable for narrow, elongated walled environments; embedded wind turbines are easily shaded by PV structures, leading to low wind energy utilization efficiency; pure wind or pure PV walls have limited functionality and cannot provide continuous day and night power supply. Furthermore, PV outputs DC power, and wind turbines output AC power, making direct convergence difficult. Conventional wiring methods easily cause circuit conflicts and poor grid connection quality. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a vertical wall-type wind and solar power generation system that addresses the shortcomings of the prior art.

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A vertical wall-type wind and solar power generation system includes multiple photovoltaic power generation units, multiple vertical axis wind turbines, wind turbine support columns, central columns, photovoltaic power generation unit frames, transverse connecting beams, pre-embedded foundations, and electrical conversion and grid connection units; The photovoltaic power generation unit frame, the wind turbine support column, the central column, and the transverse connecting beam are spliced ​​together to form an integrated wall-type load-bearing structure. The bottom ends of the wind turbine support column and the central column are fixed to the pre-embedded foundation. The vertical axis wind turbine is installed on the wind turbine support column. The photovoltaic power generation units and the vertical axis wind turbines are arranged alternately along the extension direction of the wall, and the vertical axis wind turbines are located between two adjacent photovoltaic power generation units. The photovoltaic power generation unit is composed of multiple photovoltaic panels connected in series, and the photovoltaic panels are vertically arranged within the frame of the photovoltaic power generation unit; The electrical conversion and grid connection unit is electrically connected to the photovoltaic power generation unit and the vertical axis wind turbine, respectively, and is used to collect photovoltaic DC power and wind turbine output AC power.

[0005] The beneficial effects of adopting the technical solution of this invention are as follows: Integrating photovoltaics and vertical axis wind turbines into an integrated vertical wall support structure, along with a dedicated electrical conversion and grid connection unit, allows for the full utilization of the vertical facade space of the wall by alternating vertical arrangements of the photovoltaic units and wind turbines, eliminating the need for separate land occupation and achieving composite site utilization. The integrated wall-type support structure serves the dual functions of enclosure and power generation carrier, while the shared civil engineering foundation reduces overall construction costs. The vertically arranged photovoltaic panels and vertical axis wind turbines have good wind and light adaptability, resulting in stronger power generation stability. The matching electrical conversion and grid connection unit can uniformly collect photovoltaic DC power and wind turbine frequency conversion AC power, centrally completing unified power conversion, coordinated control, and grid connection output. This simplifies the complex wiring and equipment investment of separate wind and solar power systems, enabling synchronous and stable grid connection of wind and solar power, while facilitating centralized monitoring and control of the operating status of all power generation units.

[0006] Furthermore, the transverse connecting beam is disposed on the upper edge of the photovoltaic panel and is close to or adjacent to the frame of the photovoltaic panel, which is used to improve the overall structural rigidity of the photovoltaic power generation unit along the length of the wall.

[0007] The beneficial effect of adopting the above-mentioned further solution is that the horizontal connecting beam is arranged along the edge of the photovoltaic panel, which can connect and reinforce each photovoltaic unit along the length of the wall, greatly improving the overall structural bending and wind resistance. At the same time, from a top-down view, it can block the edge of the photovoltaic panel, thus serving multiple functions such as protection, neat appearance, and simplified overall assembly.

[0008] Furthermore, the bottom of the vertical axis wind turbine's nose is higher than the upper edge of the photovoltaic panel, so that the wind-receiving area of ​​the vertical axis wind turbine is not blocked by the photovoltaic power generation unit.

[0009] The beneficial effect of adopting the above-mentioned further solution is that by setting the bottom of the vertical axis wind turbine head above the upper edge of the photovoltaic panel, the shading of the wind turbine's windward surface by the photovoltaic structure can be completely avoided, fully capturing stable upper wind energy, improving the wind turbine's power generation efficiency, and reducing the disturbance of the wind turbine's airflow to the photovoltaic panel surface, thus ensuring the long-term stable operation of the photovoltaic system.

[0010] Furthermore, the central column is positioned between adjacent photovoltaic power generation units, and the photovoltaic power generation unit frame is closely fitted with the wind turbine support column to form a continuous enclosure structure.

[0011] The beneficial effect of adopting the above-mentioned further scheme is that the photovoltaic unit is separated by the central column, and the photovoltaic frame and the wind turbine column are closely attached to form a continuous enclosure structure, which can not only ensure the orderly layout of wind and solar equipment, but also make the wall completely closed and complete, improving the site protection effect and the overall structural rigidity.

[0012] Furthermore, the electrical conversion and grid connection unit includes a combiner box, an inverter, and a box-type transformer; the DC power output from the photovoltaic power generation unit is sequentially connected to the combiner box and the inverter to complete the AC-DC conversion, and the AC power after inversion is connected to the low-voltage AC side of the box-type transformer; the AC power output from the vertical axis wind turbine is connected to the low-voltage AC side of the box-type transformer.

[0013] The beneficial effects of adopting the above-mentioned further scheme are that the photovoltaic DC and wind turbine AC circuits are respectively connected to the low-voltage side of the box-type transformer, and the DC power is connected to the grid in a unified manner after being combined and inverted. This avoids circuit conflicts caused by mixing different types of wind and solar power, simplifies the electrical topology, reduces the difficulty of protection configuration, and improves the grid-connected power quality and operational stability of the system.

[0014] Furthermore, the electrical conversion and grid connection unit also includes an energy storage converter PCS and an energy storage battery cabinet; the energy storage battery cabinet is connected to the low-voltage AC bus of the box-type transformer via the energy storage converter PCS to realize bidirectional charging and discharging regulation of electrical energy.

[0015] The beneficial effects of adopting the above-mentioned further scheme are that the energy storage battery cabinet can achieve bidirectional charging and discharging through the PCS connected to the low-voltage bus of the transformer. When there is sufficient sunlight, it stores excess photovoltaic and wind power, and releases power at night or on cloudy days to make up for the power generation gap, smooth out the fluctuation of wind and solar power output, ensure continuous and stable power supply, and improve the overall absorption and self-sufficiency of the system.

[0016] Furthermore, the vertical wall-type wind and solar co-generation system also includes cable troughs, which are continuously laid out along the overall extension direction of the wall to store and organize various connecting cables inside the system.

[0017] The beneficial effects of adopting the above-mentioned further solution are that continuous cable trays along the entire length of the wall can uniformly accommodate AC and DC cables, achieve neat and orderly arrangement of lines, avoid exposed, aged and worn cables, reduce the safety hazards of short circuits and leakage, facilitate later line maintenance and capacity expansion, and improve the overall neatness of the entire wall-mounted power generation facility.

[0018] Furthermore, the vertical wall-type wind and solar co-generation system also includes a monitoring platform and / or a mobile APP; the monitoring platform and / or mobile APP are communicatively connected to the inverter, the energy storage converter PCS, the energy storage battery cabinet and the box-type transformer, and are used to collect power generation, energy storage status, grid connection status and fault alarm information.

[0019] The beneficial effects of adopting the above-mentioned further solutions are that the monitoring platform and mobile APP can remotely collect data on power generation, energy storage, grid connection and faults, keep abreast of the system's operating status in real time, automatically execute wind, solar and energy storage coordinated control strategies based on data, realize unattended operation and maintenance, provide timely early warning of faults, significantly reduce the cost of manual inspection, and improve the reliability of the system's power supply.

[0020] Furthermore, the vertical wall-type wind and solar co-generation system also includes a clamp, which is installed on the central column and the wind turbine support column. The installation height can be adjusted vertically along the wind turbine support column and the central column to fasten the photovoltaic power generation unit frame and the transverse connecting beam to the column.

[0021] The beneficial effect of adopting the above-mentioned further solution is that by fixing the photovoltaic unit frame and the horizontal connecting beam with the vertically adjustable clamp, the photovoltaic installation height can be flexibly adjusted to adapt to different lighting environments. At the same time, it is easy to assemble and disassemble, improving the overall stability of the wall structure and the versatility of construction.

[0022] Furthermore, the photovoltaic power generation unit consists of 12 to 28 photovoltaic panels connected in series.

[0023] The beneficial effect of adopting the above-mentioned further scheme is that using 12 to 28 photovoltaic panels in series can adapt to the input voltage range of electrical conversion and grid-connected units, take into account the power generation of a single branch and line loss, and improve the system's power conversion efficiency.

[0028] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] It should be noted that similar reference numerals and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. In the description of the embodiments of the present invention, it should be noted that if terms such as "upper," "lower," "horizontal," "inner," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figures, or the orientation or positional relationship in which the product of the invention is usually placed, they are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0032] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

[0033] like Figures 1 to 3 As shown, this embodiment of the invention provides a vertical wall-type wind and solar power generation system, including multiple photovoltaic power generation units 1, multiple vertical axis wind turbines 2, wind turbine support columns 3, central column 4, photovoltaic power generation unit frame 5, horizontal connecting beam 6, pre-embedded foundation 7, and electrical conversion and grid connection unit.

[0034] The photovoltaic power generation unit frame 5, the wind turbine support column 3, the central column 4, and the transverse connecting beam 6 are spliced ​​together to form an integrated wall-like load-bearing structure. The bottom ends of the wind turbine support column 3 and the central column 4 are fixed to the pre-embedded foundation 7, and the vertical axis wind turbine 2 is mounted on the wind turbine support column 3. Using the pre-embedded foundation 7 as the load-bearing base for all vertical components, the wind turbine support column 3 and the central column 4 are simultaneously anchored to the pre-embedded foundation 7, together forming the longitudinal main load-bearing skeleton of the wall. The photovoltaic power generation unit frame 5 and the transverse connecting beam 6 are assembled with the columns to form an integrated wall-like load-bearing structure, simultaneously achieving the dual functions of site isolation and protection as well as support for wind and solar power generation equipment.

[0035] The photovoltaic power generation unit 1 and the vertical axis wind turbine 2 are arranged alternately along the extension direction of the wall, and the vertical axis wind turbine 2 is located between two adjacent photovoltaic power generation units 1.

[0036] The photovoltaic power generation unit 1 is composed of multiple photovoltaic panels connected in series, and the photovoltaic panels are vertically arranged within the photovoltaic power generation unit frame 5. Figure 2 As shown, when viewed from above, because the photovoltaic panels are installed vertically, only the approximately 35mm wide frame thickness of the photovoltaic panels is visible in the top view; the glass surface on the front of the photovoltaic panels is not visible. The north side of the upper frame of the photovoltaic panels is obscured by the horizontal connecting beam 6, therefore appearing as a continuous horizontal beam line in the top view.

[0037] The electrical conversion and grid connection unit is electrically connected to the photovoltaic power generation unit 1 and the vertical axis wind turbine 2, respectively, and is used to collect photovoltaic DC power and wind turbine output AC power.

[0038] The beneficial effects of adopting the technical solution of this invention are as follows: Integrating photovoltaics and vertical axis wind turbines into an integrated vertical wall support structure, along with a dedicated electrical conversion and grid connection unit, allows for the full utilization of the vertical facade space of the wall by alternating vertical arrangements of the photovoltaic units and wind turbines, eliminating the need for separate land occupation and achieving composite site utilization. The integrated wall-type support structure serves the dual functions of enclosure and power generation carrier, while the shared civil engineering foundation reduces overall construction costs. The vertically arranged photovoltaic panels and vertical axis wind turbines have good wind and light adaptability, resulting in stronger power generation stability. The matching electrical conversion and grid connection unit can collect photovoltaic DC power and wind turbine frequency-converted AC power, centrally completing unified power conversion, coordinated control, and grid connection output. This simplifies the complex wiring and equipment investment of separate wind and solar power systems, enabling synchronous and stable grid connection of wind and solar power, while facilitating centralized monitoring and control of the operating status of all power generation units.

[0039] Furthermore, the transverse connecting beam 6 is disposed along the upper edge of the photovoltaic panel and is closely attached to or adjacent to the frame of the photovoltaic panel, thereby improving the overall structural rigidity of the photovoltaic power generation unit 1 along the length of the wall. The transverse connecting beam 6 is attached to the upper edge of the photovoltaic panel and connected to the photovoltaic frame, connecting the segmented photovoltaic power generation unit frames 5 into a whole along the length of the wall, dispersing the wind pressure and self-weight load borne by each photovoltaic unit, and improving the overall bending and wind resistance rigidity of the entire wall along its length.

[0040] The beneficial effect of adopting the above-mentioned further solution is that the transverse connecting beam 6 is arranged along the edge of the photovoltaic panel, which can connect and reinforce each photovoltaic power generation unit 1 along the length of the wall, greatly improving the overall structural bending and wind resistance. At the same time, it can block the edge of the photovoltaic panel from the top view, which has multiple functions of protection, neat appearance and simplified overall assembly.

[0041] Furthermore, the bottom of the nose of the vertical axis wind turbine 2 is higher than the upper edge of the photovoltaic panel, so as to prevent the wind-receiving area of ​​the vertical axis wind turbine 2 from being blocked by the photovoltaic power generation unit 1.

[0042] The beneficial effect of adopting the above-mentioned further solution is that by setting the bottom of the vertical axis wind turbine 2 head above the upper edge of the photovoltaic panel, the shading of the vertical axis wind turbine 2 wind-receiving surface by the photovoltaic structure can be completely avoided, so as to fully capture stable upper wind energy, improve the power generation efficiency of the wind turbine, and at the same time reduce the disturbance of the wind turbine airflow to the photovoltaic panel surface, and ensure the long-term stable operation of the photovoltaic.

[0043] Furthermore, the central column 4 is positioned between adjacent photovoltaic power generation units 1, and the photovoltaic power generation unit frame 5 is tightly fitted with the wind turbine support column 3 to form a continuous enclosure structure. Preferably, the photovoltaic power generation unit frame 5 includes a vertical frame, a bottom support beam, and a back support beam. The vertical frame surrounds both sides of the photovoltaic panel, the bottom support beam supports the lower end of the photovoltaic panel, and the back support beam provides lateral support from the back of the photovoltaic panel. The three components work together to form a complete rigid frame, which, together with the transverse connecting beam 6 and the clamps, bears the self-weight of the photovoltaic panel and the wind load.

[0044] The beneficial effect of adopting the above-mentioned further scheme is that the central column 4 separates the photovoltaic power generation unit 1, the photovoltaic power generation unit frame 5 and the wind turbine support column 3 to form a continuous enclosure structure, which can not only ensure the orderly layout of wind and solar equipment, but also make the wall completely closed and complete, improving the site protection effect and the overall structural rigidity.

[0045] like Figure 3As shown, the electrical conversion and grid connection unit further includes a combiner box 81, an inverter 82, and a box-type transformer 83. The DC power output from the photovoltaic power generation unit 1 is sequentially connected to the combiner box 81 and the inverter 82 to complete the AC-DC conversion. The inverted AC power is then connected to the low-voltage AC side of the box-type transformer 83. The AC power output from the vertical axis wind turbine 2 is connected to the low-voltage AC side of the box-type transformer 83. The low-voltage DC power output from the photovoltaic power generation unit 1 is first uniformly fed into the combiner box 81 to complete the DC branch current collection and overcurrent lightning protection, and then transmitted to the inverter 82. The inverter 82 converts the DC power into power frequency AC power through power electronic conversion and transmits it to the low-voltage AC bus inside the box-type transformer 83. The vertical axis wind turbine 2 directly outputs power frequency AC power without the need for a DC conversion stage and is directly connected in parallel to the same low-voltage AC bus, realizing the convergence of photovoltaic power and wind turbine power on the low-voltage side.

[0046] The beneficial effects of adopting the above-mentioned further scheme are that the photovoltaic DC and wind turbine AC circuits are respectively connected to the low-voltage side of the box-type transformer 83, and the DC power is connected to the grid in a unified manner after being combined and inverted, avoiding circuit conflicts caused by mixing different types of wind and solar power, simplifying the electrical topology, reducing the difficulty of protection configuration, and improving the grid-connected power quality and operational stability of the system.

[0047] Furthermore, the electrical conversion and grid connection unit also includes an energy storage converter (PCS) and an energy storage battery cabinet 84. The energy storage battery cabinet 84 is connected to the low-voltage AC bus of the box-type transformer 83 via the energy storage converter (PCS) to achieve bidirectional charging and discharging regulation of electrical energy. The energy storage battery cabinet 84 stores DC power and is equipped with the energy storage converter (PCS) as a bidirectional AC / DC conversion device. When there is sufficient sunlight and wind speed, and the system's power generation exceeds the load consumption, the PCS operates in rectification charging mode, converting excess AC power from the bus into DC power and storing it in the energy storage battery cabinet 84. When there is weak sunlight, no wind, or a large power load, the PCS switches to inverter discharging mode, inverting the battery's DC power into AC power and feeding it back to the low-voltage bus, thereby bidirectionally regulating the bus's power surplus and deficit and smoothing out intermittent power output fluctuations from wind and solar power.

[0048] The beneficial effects of adopting the above-mentioned further scheme are that the energy storage battery cabinet 84 can achieve bidirectional charging and discharging by connecting to the low-voltage bus of the transformer substation through the PCS. When there is sufficient sunlight, it stores excess photovoltaic and wind power, and releases power at night or on cloudy days to make up for the power generation gap, smooth out the fluctuation of wind and solar power output, ensure continuous and stable power supply, and improve the overall absorption and self-sufficiency of the system.

[0049] The electrical conversion and grid connection unit also includes a controller 85, which is communicatively connected to the combiner box 81, inverter 82, energy storage converter PCS, energy storage battery cabinet 84, box-type transformer 83, and vertical axis wind turbine 2. The controller 85 has a built-in energy management main control unit, used to centrally collect power generation, energy storage, and grid connection operation data of the entire system, execute wind-solar-storage coordinated charging and discharging scheduling logic, and has electrical fault identification and branch circuit protection shutdown functions. It also enables local parameter debugging and data transmission relay for remote monitoring platforms.

[0050] Furthermore, the vertical wall-type wind and solar co-generation system also includes cable troughs, which are continuously laid out along the overall extension direction of the wall to store and organize various connecting cables inside the system.

[0051] The beneficial effects of adopting the above-mentioned further solution are that continuous cable trays along the entire length of the wall can uniformly accommodate AC and DC cables, achieve neat and orderly arrangement of lines, avoid exposed, aged and worn cables, reduce the safety hazards of short circuits and leakage, facilitate later line maintenance and capacity expansion, and improve the overall neatness of the entire wall-mounted power generation facility.

[0052] Furthermore, the vertical fence-type wind and solar co-generation system also includes a monitoring platform and / or a mobile APP 10. The monitoring platform and / or mobile APP 10 are communicatively connected to the inverter 82, the energy storage converter PCS, the energy storage battery cabinet 84, and the box-type transformer 83. It is used to collect power generation, energy storage status, grid connection status, and fault alarm information, and to perform coordinated wind-solar-storage control. When the total power generation of photovoltaic and wind turbines exceeds the on-site load demand, the platform issues a charging command to the energy storage converter PCS to store excess energy in the energy storage battery cabinet 84, while simultaneously limiting excess power on the generation side and stabilizing the bus electrical parameters. When insufficient sunlight or no wind causes wind and solar power generation to fail to meet load demand, the platform issues a discharge command to control the energy storage battery to output power through the PCS inverter, making up for the power generation shortfall and ensuring continuous power supply. When sudden changes in sunlight or wind speed cause drastic fluctuations in output power, the platform dynamically adjusts the energy storage charging and discharging power to quickly smooth out power fluctuations, stabilize grid connection voltage and frequency, and improve grid connection power quality. After any device reports a fault alarm, the platform simultaneously executes coordinated control, issues power limiting and branch shutdown commands to isolate the faulty branch, adjusts the output power of the remaining power generation and energy storage to prevent the fault from spreading, and pushes fault reminders to the mobile APP to achieve remote early warning.

[0053] The beneficial effects of adopting the above-mentioned further solutions are that the monitoring platform and mobile APP can remotely collect data on power generation, energy storage, grid connection and faults, keep abreast of the system's operating status in real time, automatically execute wind, solar and energy storage coordinated control strategies based on data, realize unattended operation and maintenance, provide timely early warning of faults, significantly reduce the cost of manual inspection, and improve the reliability of the system's power supply.

[0054] Furthermore, the vertical wall-type wind and solar co-generation system also includes a clamp 11, which is installed on the central column 4 and the wind turbine support column 3. The installation height can be adjusted vertically along the wind turbine support column 3 and the central column 4 to fasten the photovoltaic power generation unit frame 5 and the transverse connecting beam 6 to the column.

[0055] The beneficial effect of adopting the above-mentioned further solution is that by fixing the photovoltaic unit frame and the horizontal connecting beam 6 with the vertically adjustable clamp 11, the photovoltaic installation height can be flexibly adjusted to adapt to different lighting environments. At the same time, it is easy to disassemble and assemble, improving the overall stability of the wall structure assembly and the versatility of construction.

[0056] Furthermore, the photovoltaic power generation unit 1 is composed of 12 to 28 photovoltaic panels connected in series.

[0057] The beneficial effect of adopting the above-mentioned further scheme is that using 12 to 28 photovoltaic panels in series can adapt to the input voltage range of the electrical conversion and grid-connected units, taking into account the power generation of a single branch and line losses, and improving the system's power conversion efficiency. Preferably, this embodiment is illustrated with 26 photovoltaic panels in series.

[0058] A maintenance access road can be set up on one side of the wall-type load-bearing structure. The access road is parallel to the arrangement direction of the photovoltaic power generation unit 1 and the vertical axis wind turbine 2, and the width of the access road is not less than 1000mm. The parallel maintenance access road provides ample operating space for maintenance personnel, facilitating the inspection, disassembly, and fault repair of photovoltaic, wind turbine, and electrical equipment, avoiding the safety risks of high-altitude operations, and improving the convenience and safety of subsequent maintenance operations.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
