Description

Technical Field

[0001] The embodiments of the present application relate to the field of photovoltaic power generation technology, and in particular to a method for typhoon-resistant deployment of photovoltaic bracket arrays. Background Art

[0002] At present, with the continuous development of large-scale ground photovoltaic power generation projects, flat and open ground scenes are becoming less and less, and there are more and more application scenes such as hillsides, swamps, and water treatment plants. The small-span dense column-type purlin photovoltaic bracket suitable for the aforementioned application scenes is not suitable for the latter scene, and the large-span flexible bracket is gradually being promoted.

[0003] The long-span flexible bracket introduces steel cables as the main support, which increases the span between columns by 5-10 times from 6 meters of the purlin type to more than 30 meters, greatly improving the adaptability to photovoltaic installation scenarios. However, as the project progresses, it is found that the long-span flexible bracket has the following problems: (1) The photovoltaic modules installed on the long-span steel cables will vibrate under the action of wind loads, causing fatigue failure of the connectors and hidden cracks in the cells of the photovoltaic modules; (2) Since it is necessary to avoid the bracket being blown over by excessive wind pressure, the inclination angle of the module should not be too large, and it is often smaller than the local optimal inclination angle, resulting in power generation loss; (3) Photovoltaic brackets are generally designed according to the wind load conditions of once in 50 years, but under extreme weather conditions such as typhoons, the wind force may often reach an extreme peak. The existing scheme lacks wind shelter measures and there is a risk of being blown over and damaged.

[0004] Therefore, medium-span flexible brackets with a span of 16-20 meters have appeared on the market. The medium-span flexible bracket partially reduces the problem of wind-induced vibration, but because the inclination angle is a fixed value and cannot be adjusted according to weather conditions, the problem of "low power generation and inability to reduce wind pressure to ensure safety under extreme weather conditions" remains unsolved. In addition, the photovoltaic bracket has evolved from a small-span rigid purlin support structure to a medium-span flexible support structure, which brings greater risks in resisting extreme wind pressure, especially typhoons.

[0005] Therefore, there is an urgent need for a typhoon-resistant deployment method for photovoltaic support arrays. Summary of the invention

[0050] The exemplary embodiments of the present application will be described in more detail below in conjunction with the accompanying drawings in the embodiments of the present application. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to enable the scope of the present application to be fully communicated to those skilled in the art.

[0051] In a first aspect of an embodiment of the present application, a method for typhoon-resistant deployment of a photovoltaic bracket array is provided, the method comprising: determining the type of wind pressure that the project site is subjected to when affected by a typhoon based on comprehensive geographic information of the project site, the comprehensive geographic information comprising at least: a project redline map, a contour map, surrounding terrain data, and meteorological data of the area; based on the type of wind pressure that the project site is subjected to, dividing the project site into a plurality of wind pressure type areas; and according to different wind pressure types within each of the wind pressure type areas, respectively deploying photovoltaic brackets corresponding to the different wind pressure types within each of the wind pressure type areas.

[0052] Specifically, in the embodiment of the present application, it is first necessary to determine the project location of the photovoltaic bracket array project, and then determine the type of wind pressure that the project location will withstand when affected by a typhoon by querying the comprehensive geographic information of the project location. In practical applications, the comprehensive geographic information can be at least one of the project redline map, contour map, surrounding terrain data, and meteorological data of the project area. It should be noted that the comprehensive geographic information can be obtained by querying relevant agencies such as the local urban planning bureau, geographic information system (GIS) department, and meteorological bureau.

[0053] Furthermore, after determining the type of wind pressure that the project site is subjected to when affected by a typhoon, the project site is divided into a plurality of wind pressure type areas according to different wind pressure types, wherein different wind pressure type areas contain different wind pressure types.

[0054] Furthermore, for different wind pressure types contained in different wind pressure type areas, photovoltaic brackets corresponding to different wind pressure types are arranged in each different wind pressure type area.

[0055] The embodiment of the present application divides the project site into multiple wind pressure type areas according to the different effects of typhoons on different areas of the photovoltaic bracket array project site, and classifies and layouts different bracket types in different wind pressure type areas, thereby effectively improving the typhoon resistance of the photovoltaic bracket array.

[0056] In a preferred embodiment of the present application, determining the type of wind pressure that the project location is subjected to when affected by a typhoon based on the comprehensive geographical information of the project location includes:

[0057] Based on the comprehensive geographic information, draw a typhoon impact diagram and a local wind pressure distribution cloud map of the project location;

[0058] Draw a wind pressure type zoning map of the project location based on the typhoon impact schematic diagram and the local wind pressure distribution cloud map;

[0059] Based on the wind pressure type zoning map, determine the type of wind pressure that the project site will be subjected to when affected by a typhoon.

[0060] In this embodiment, the comprehensive geographic information of the project location: the project red line map, contour map, surrounding terrain data and meteorological data of the project area are integrated to draw a typhoon impact schematic diagram and a local wind pressure distribution cloud map.

[0061] Figure 1 A schematic diagram of typhoon impact provided in an embodiment of the present application; Figure 2 A local wind pressure distribution cloud map provided in an embodiment of the present application.

[0062] Reference Figure 1 The typhoon impact diagram shown can be used to infer the impact of the typhoon on different areas of the project location based on the typhoon's movement direction and the typhoon's cyclone direction. Figure 2 The local wind pressure distribution cloud diagram shown can determine the wind pressure types in different areas of the project site when it is affected by a typhoon. Figure 2 It can be seen from the figure that when the typhoon moves from south to north, the wind pressure types from south to north at the project location are positive high wind pressure and positive low wind pressure, that is, the wind pressure weakens from south to north. When the typhoon moves from north to south, the wind pressure types from north to south at the project location are negative high wind pressure and negative low wind pressure, that is, the wind pressure weakens from north to south.

[0063] In this embodiment, according to Figure 1 Schematic diagram of typhoon impact and Figure 2 The local wind pressure distribution cloud map is used to draw a wind pressure type zoning map of the project location. Based on the wind pressure type zoning map, it is possible to determine the different types of wind pressure that different areas of the project location are subjected to when affected by a typhoon.

[0064] In a preferred embodiment of the present application, the wind pressure types include: first intensity wind pressure, second intensity wind pressure and third intensity wind pressure;

[0065] Based on the type of wind pressure borne by the project site, the project site is divided into multiple wind pressure type areas, including:

[0066] Determine the area where the first-intensity wind pressure is located as a wind pressure limit area, determine the area where the second-intensity wind pressure is located as a wind pressure transition area, and determine the area where the third-intensity wind pressure is located as a wind pressure weakening area;

[0067] The wind pressure intensities of the first wind pressure intensity, the second wind pressure intensity, and the third wind pressure intensity decrease in sequence.

[0068] In this embodiment, by Figure 1 The typhoon impact diagram determines the direction of typhoon movement and Figure 2 The local wind pressure distribution cloud map is used to determine the wind pressure intensity in different areas of the project location in the direction of the current typhoon movement. The two information are integrated to obtain a wind pressure type zoning map.

[0069] In this embodiment, the wind pressure intensity is divided into a first intensity wind pressure, a second intensity wind pressure and a third intensity wind pressure, wherein the wind pressure intensities of the first intensity wind pressure, the second intensity wind pressure and the third intensity wind pressure decrease in sequence.

[0070] Furthermore, the project site is divided into wind pressure types according to the wind pressure intensity. The area with the first intensity wind pressure is determined as the wind pressure limit area, the area with the second intensity wind pressure is determined as the wind pressure transition area, and the area with the third intensity wind pressure is determined as the wind pressure weakening area.

[0071] In the present application, the wind pressure limit zone is divided into a positive wind pressure limit zone, a negative wind pressure limit zone and a variable wind pressure limit zone according to the wind direction of the typhoon; the wind pressure transition zone is divided into a positive wind pressure transition zone, a negative wind pressure transition zone and a variable wind pressure transition zone; the wind pressure weakening zone is divided into a positive wind pressure weakening zone, a negative wind pressure weakening zone and a variable wind pressure weakening zone;

[0072] Among them, positive wind pressure is the south wind pressure, negative wind pressure is the north wind pressure, and variable wind pressure is the east or west wind pressure.

[0073] like Figure 3 A positive wind pressure type zoning diagram is shown. Figure 4 A negative wind pressure type zoning diagram is shown and Figure 5 An eastward variable wind direction wind pressure type zoning diagram and Figure 6 A westerly variable wind direction wind pressure type zoning map is shown. Figure 3-6 In the figure, A represents the wind pressure limit area, B represents the wind pressure transition area, and C represents the wind pressure weakening area. Figure 3 It can be seen from the figure that when the typhoon moves from south to north, the wind pressure types of different areas of the project location are divided according to the wind pressure intensity. The more southerly the area is, the greater the wind pressure intensity is. Therefore, Figure 3 The project site is divided from south to north into positive wind pressure limit zone A1, positive wind pressure transition zone B1 and positive wind pressure weakening zone C1.

[0074] Similarly, from Figure 4 It can be seen from the figure that when the typhoon moves from north to south, the wind pressure types of different areas of the project location are divided according to the wind pressure intensity. The more northerly the area is, the greater the wind pressure intensity is. Therefore, Figure 4 The project site is divided into negative wind pressure limit zone A2, negative wind pressure transition zone B2 and negative wind pressure weakening zone C2 from north to south.

[0075] from Figure 5 It can be seen from the figure that when the typhoon moves from east to west, the wind pressure types of different areas of the project location are divided according to the wind pressure intensity. The more eastward the area, the greater the wind pressure intensity. Therefore, Figure 5 The project site is divided from east to west into variable wind pressure limit zone A3, variable wind pressure transition zone B3 and variable wind pressure weakening zone C3.

[0076] from Figure 6 It can be seen from the figure that when the typhoon moves from west to east, the wind pressure types of different areas of the project location are divided according to the wind pressure intensity. The more westward the area, the greater the wind pressure intensity. Therefore, Figure 6 The project site is divided into variable wind pressure limit area A4, variable wind pressure transition area B4 and variable wind pressure weakening area C4 from west to east. Figure 3 The positive wind pressure limit area A1, the positive wind pressure transition area B1 and the positive wind pressure weakening area C1 are collectively referred to as the positive wind pressure area. Figure 4 The negative wind pressure limit area A2, the negative wind pressure transition area B2 and the negative wind pressure weakening area C2 are collectively referred to as the negative wind pressure area. Figure 5 The variable wind pressure limit area A3, the variable wind pressure transition area B3 and the variable wind pressure weakening area C3 are collectively referred to as the eastward variable wind pressure area or Figure 6 The variable wind pressure limit zone A4, the variable wind pressure transition zone B4 and the variable wind pressure weakening zone C4 are collectively referred to as the westward variable wind pressure zone. It should be noted that the positive wind pressure zone and the negative wind pressure zone cannot exist at the same time, and the eastward variable wind pressure zone and the westward variable wind pressure zone cannot exist at the same time.

[0077] In another preferred embodiment of the present application, according to the different wind pressure types in each of the wind pressure type areas, photovoltaic brackets corresponding to the different wind pressure types are arranged in each of the wind pressure type areas, including:

[0078] In the wind pressure limit area, a first span adjustable tilt angle flexible bracket corresponding to the first wind pressure intensity is arranged;

[0079] In the wind pressure transition zone and / or the wind pressure weakening zone, a second span fixed inclination flexible bracket corresponding to the second wind pressure intensity is arranged;

[0080] The span of the first span adjustable tilt angle flexible bracket is smaller than the span of the second span fixed tilt angle flexible bracket.

[0081] Specifically, in an embodiment of the present application, photovoltaic brackets matching the corresponding wind pressure types are arranged in these areas according to the areas with different wind pressure types. Specifically, in the wind pressure limit area, a first span adjustable tilt flexible bracket corresponding to the first wind pressure intensity is arranged. The first span adjustable tilt flexible bracket can adjust the inclination angle according to the specific situation to adapt to high wind pressure conditions. In the wind pressure transition zone and / or the wind pressure reduction zone, a second span fixed tilt flexible bracket matching the second wind pressure intensity is installed. The inclination angle of the second span fixed tilt flexible bracket is fixed, which is suitable for medium wind pressure or reduced wind pressure. It should be emphasized that the span of the first span adjustable tilt flexible bracket is smaller than the span of the second span fixed tilt flexible bracket. This layout method can effectively meet the needs of photovoltaic bracket arrays under different wind pressure conditions and ensure the stability and performance of the system.

[0082] In this embodiment, in the wind pressure limit area, there is usually a higher wind pressure intensity, so this application uses a first span adjustable inclination flexible bracket. The uniqueness of this bracket is that it can adjust the angle according to the actual wind pressure conditions to minimize the typhoon resistance borne by the bracket, while ensuring the stability of the system, so that the photovoltaic components can still maintain efficient operation under extreme wind pressure conditions. In the wind pressure transition zone and / or the wind pressure reduction zone, the wind pressure is relatively low, so this application selects a second span fixed inclination flexible bracket. Although this bracket does not have the function of angle adjustment, due to the low wind pressure, its fixed inclination is sufficient to maintain the stability of the system, and it is also more economical and efficient.

[0083] In this embodiment, the span of the first span adjustable inclination flexible bracket is set to be smaller than the span of the second span fixed inclination flexible bracket. This design takes into account that the brackets in the wind pressure limit area need to be more compact and flexible in order to adapt to the challenge of high wind pressure, while in the wind pressure transition zone and / or the wind pressure reduction area, the wind pressure intensity is weaker, so the bracket can be more stable and can have a larger span. This not only improves the performance and stability of photovoltaic modules, but also helps to reduce overall costs. By selecting the appropriate bracket type and layout method according to the requirements of different wind pressure types, the present application can maximize the potential of photovoltaic modules while ensuring that the system can operate reliably under various meteorological conditions. This innovative design brings new possibilities for the development of the renewable energy field.

[0084] Figure 7 A schematic diagram of the layout of a photovoltaic support in a positive wind pressure area provided in an embodiment of the present application is provided. Figure 8 A schematic diagram of the layout of a photovoltaic support in a negative wind pressure area provided in an embodiment of the present application. Figure 7As shown in FIG. 1 , when the typhoon wind direction is positive, a first span adjustable tilt flexible bracket is arranged in the positive wind pressure limit area A1, and a second span fixed tilt flexible bracket is arranged in the positive wind pressure transition area B1 and the positive wind pressure weakening area C1. Figure 8 As shown, when the wind direction of the typhoon is negative, the first span adjustable tilt flexible bracket is arranged in the negative wind pressure limit area A2, and the second span fixed tilt flexible bracket is arranged in the negative wind pressure transition area B2 and the negative wind pressure weakening area C2. Similarly, in the variable wind pressure area, the layout scheme of the photovoltaic bracket is the same as that in the positive wind pressure area and the negative wind pressure area, and this application will not be repeated here.

[0085] In another preferred embodiment of the present application, after respectively arranging photovoltaic brackets corresponding to the different wind pressure types in each of the wind pressure type areas, the wind direction of the typhoon is determined according to the wind pressure type; and according to the wind direction of the typhoon, the inclination angle of the photovoltaic component of the first span adjustable inclination flexible bracket in the wind pressure limit area is adjusted to a preset angle so that the front side of the photovoltaic component bears the wind pressure.

[0086] In this embodiment, in areas with different wind pressure types, adaptive photovoltaic brackets, i.e., first span adjustable tilt flexible brackets and second span fixed tilt flexible brackets, are arranged according to actual conditions to meet specific needs of each area.

[0087] Accurately determine the typhoon's wind direction through meteorological data or wind speed sensors. This is a critical step because the wind direction determines the direction of the main wind pressure on the photovoltaic modules.

[0088] Furthermore, according to the determined typhoon wind direction, the system will automatically adjust the inclination angle of the photovoltaic module on the first span adjustable inclination flexible bracket in the wind pressure limit area to a preset angle. The preset angle enables the front of the photovoltaic module to withstand the wind pressure from the typhoon wind direction to the greatest extent, thereby ensuring the stability and safety of the system.

[0089] In this embodiment, the inclination angle of the photovoltaic module is adjusted so that the front of the photovoltaic module faces the wind direction of the typhoon, so that the system can better cope with the wind pressure brought by the typhoon. Based on this, the structure of the photovoltaic module can not only reduce the impact of wind pressure, but also reduce the risk of the system, ensuring that it can still operate normally under extreme weather conditions.

[0090] In a preferred embodiment of the present application, when the wind pressure of the typhoon is positive wind pressure, the inclination angle of the photovoltaic assembly of the first span adjustable inclination flexible bracket in the positive wind pressure limit area is adjusted to a preset angle toward the south; or,

[0091] When the wind pressure of the typhoon is negative, the inclination angle of the photovoltaic assembly of the first span adjustable inclination flexible bracket in the negative wind pressure limit area is adjusted toward the north to a preset angle; or,

[0092] When the wind pressure of a typhoon is variable, the inclination angle of the photovoltaic assembly of the first span adjustable inclination flexible bracket within the variable wind pressure limit area is adjusted to a preset angle toward the east or west.

[0093] In this embodiment, the inclination of the photovoltaic module is adjusted according to the wind pressure direction of the typhoon to minimize the impact of the typhoon wind pressure on the system. Specifically, when the wind pressure of the typhoon is positive wind pressure, the system will automatically adjust the inclination of the photovoltaic module on the first span adjustable inclination flexible bracket in the wind pressure limit area to a preset angle toward the south to ensure that the photovoltaic module faces the direction of the typhoon, which can minimize the impact of wind pressure. When the wind pressure of the typhoon is negative wind pressure, the system will adjust the inclination of the photovoltaic module on the first span adjustable inclination flexible bracket in the negative wind pressure limit area to a preset angle toward the north. In this way, the photovoltaic module can resist the wind pressure from the opposite direction to the greatest extent. When the wind pressure of the typhoon is variable wind pressure, the system adjusts the inclination of the photovoltaic module on the first span adjustable inclination flexible bracket in the variable wind pressure limit area to a preset angle toward the east or west to adjust according to the actual wind pressure direction. Thereby ensuring that the photovoltaic module can maintain optimal performance under the changing wind pressure direction.

[0094] This application automatically adjusts the inclination of the photovoltaic modules to a preset angle according to the wind pressure direction of the typhoon to minimize the impact of the typhoon on the system. This not only improves the stability of the system, but also reduces maintenance and repair costs, ensuring the reliability and continuous performance of the photovoltaic system under extreme weather conditions.

[0095] Fig. 9 A schematic diagram of angle adjustment of a first span adjustable tilt flexible bracket in a positive wind pressure limit zone under positive wind pressure provided in an embodiment of the present application; Fig.10 A schematic diagram of adjusting the angle of a first span adjustable tilt flexible bracket in a negative wind pressure limit zone under negative wind pressure provided in an embodiment of the present application; Fig.11 A schematic diagram of angle adjustment of a first span adjustable tilt flexible bracket in a variable wind pressure limit zone under westward variable wind pressure provided in an embodiment of the present application; Fig.12 A schematic diagram of adjusting the angle of a first span adjustable inclination flexible bracket in a variable wind pressure limit zone under eastward variable wind pressure provided by an embodiment of the present application. Figure 9-12As shown, when a typhoon comes, the first to greet the typhoon is the photovoltaic bracket located in the wind pressure limit zone, that is, the first span adjustable tilt flexible bracket. The first span adjustable tilt flexible bracket is adjusted to the direction of the typhoon and the angle is adjusted from the original 30° to the preset angle. Therefore, when the typhoon passes, the photovoltaic components on the first span adjustable tilt flexible bracket play a role in diverting and unloading the typhoon, thereby reducing the wind pressure blowing towards the wind pressure transition zone and the wind pressure reduction zone. Therefore, the second span fixed tilt flexible bracket in the wind pressure transition zone and the wind pressure reduction zone does not need to be adjusted in angle. In practical applications, the preset angle is generally between 5°-10°, which can be determined according to the intensity of the typhoon, and this application does not specifically limit it here. It should be noted that since the wind pressure may come from different directions in the variable partial pressure limit zone, Figure 11-12 As shown, the photovoltaic components of the second span fixed tilt angle flexible bracket are arranged at a flat angle to better reduce the impact of typhoons.

[0096] In a preferred embodiment of the present application, in the variable wind pressure limit area, the span of the first span-adjustable tilt-angle flexible bracket is shortened.

[0097] In this embodiment, considering that the direction of wind pressure is variable within the variable wind pressure limit zone, in order to ensure that the photovoltaic bracket can better withstand the impact of typhoons, the span of the first span adjustable inclination flexible bracket within the variable wind pressure limit zone can be shortened, thereby making the bracket more compact and ensuring the performance of the photovoltaic module under variable wind pressure conditions.

[0098] This embodiment can better resist wind pressure from different directions by shortening the span of the first span adjustable tilt angle flexible bracket in the variable wind pressure limit area, thereby improving the reliability of the system, helping to reduce damage risks, reduce maintenance costs, and extend the life of photovoltaic modules.

[0099] In a preferred embodiment of the present application, in the wind pressure limit area, the first span adjustable tilt flexible bracket has a reinforcement component. The reinforcement component at least includes: a component for reinforcing the first span adjustable tilt flexible bracket, a component for combining tension and compression of component connectors, and a damping and shock absorbing component.

[0100] Taking the variable wind pressure limit area as an example, Fig.13 A schematic diagram of the strength layout of a support under eastward variable wind pressure provided in an embodiment of the present application; Fig.14 A schematic diagram of the strength layout of a support under variable wind pressure in the west provided in the embodiment of the present application. Figure 13-14 As shown, reinforced brackets are arranged in the variable wind pressure limit areas A3 and A4, and standard brackets are arranged in the variable wind pressure transition areas B3 and B4 and the variable wind pressure weakening areas C3 and C4.

[0101] In this embodiment, the first span adjustable tilt angle flexible bracket in the wind pressure limit area adopts a reinforcement component to improve the stability and wind resistance of the bracket, and these reinforcement components include at least one of the following:

[0102] Components for strengthening the first span adjustable tilt flexible bracket: These components are specially designed to increase the structural strength and stability of the bracket. They can include additional support rods, support frames, or other forms of structural elements to increase the bracket's load-bearing capacity and ability to resist external wind pressure.

[0103] Components Tension and compression components: These components are used to strengthen the connection points of the bracket to ensure that the connection between the various components is firm and reliable.
