DETAILED DESCRIPTION

[0023] The main purpose of the present invention is to provide a method for automatically generating photovoltaic component arrangement drawings; it realizes automatic drawing of component arrangement files by relying on computers, and can quickly generate drawings in a short time.

[0024] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" or "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0025] For ease of understanding, the specific process of the embodiment of the present invention is described below. Figure 1 , is a schematic diagram of an embodiment of a method for automatically generating a photovoltaic module arrangement drawing in an embodiment of the present invention, comprising: Step 101: Determine the location information of the installable area of ​​the photovoltaic components and the layout parameters of each photovoltaic component based on the acquired photovoltaic component installation related information.

[0026] It is understandable that the execution subject of the present invention may be a method for automatically generating a photovoltaic module layout drawing, or may be a terminal or a server, which is not specifically limited here. The embodiment of the present invention is described by taking a server as an execution subject.

[0027] The above-mentioned execution entity can obtain the relevant information about the installation of photovoltaic modules through wired connection or wireless connection; the above-mentioned relevant information about the installation of photovoltaic modules includes site information, photovoltaic module parameters, meteorological data and installation requirements. The above-mentioned execution entity can select photovoltaic system design software, such as PVsyst, Helioscope, etc.; the above-mentioned relevant information about the installation of photovoltaic modules can be imported or created through the terrain modeling function of the software. Ensure the precision and accuracy of the model so that the subsequent arrangement of modules can meet the actual site conditions.

[0028] It should be noted that the above-mentioned wireless connection methods may include but are not limited to 3G / 4G connection, WiFi connection, Bluetooth connection, WiMAX connection, Zigbee connection, UWB (ultra wideband) connection, and other wireless connection methods currently known or to be developed in the future.

[0029] Optionally, obtain information related to the installation of photovoltaic components, wherein the information related to the installation of photovoltaic components includes basic geographic information, photovoltaic component parameter information and obstacle information; determine the location information of the installable area of ​​the photovoltaic components based on the basic geographic information and the obstacle information; and set the layout parameters of each photovoltaic component based on the photovoltaic component parameter information.

[0030] The above basic geographic information can be the site information of the photovoltaic project, such as the topographic map of the site, aerial photos, etc.; the site information is used as the base map for the layout of photovoltaic modules. These base maps should contain basic information such as the size, shape, slope, etc. of the site; the above photovoltaic module parameter information includes the size (length, width, height), power, voltage, current and other electrical parameters of the module, as well as the installation method (such as fixed angle, adjustable angle, etc.) and orientation of the module. These parameters will be used to calculate the layout and performance of the photovoltaic module; the above obstacles include buildings, poles, trees, etc.; the above obstacle information includes the position, shape, height, width and other geometric information of each obstacle, as well as its shadow blocking of the photovoltaic module. For example, the shadow blocking range of the obstacle on the photovoltaic module at different times can be calculated by combining the geometric shape of the obstacle with the information such as the solar altitude angle and azimuth. According to the collected obstacle information and the topographic information of the site, the installation area of ​​the photovoltaic module is determined. Remove areas blocked by shadows from obstacles and areas that are not suitable for installing PV modules, such as areas with excessively steep terrain slopes or unstable soil conditions. The above layout parameters include the installation azimuth and inclination of PV modules and the minimum spacing of PV arrays. The azimuth is usually determined based on the geographical location of the site and the movement trajectory of the sun to ensure that the PV modules can receive solar radiation to the greatest extent. The inclination needs to consider factors such as the slope of the site, the type of PV modules and the installation method, and is generally selected within the optimal local inclination range. The minimum spacing of PV arrays should meet the requirements of avoiding shadows between adjacent PV modules, and is usually calculated based on factors such as the size of the PV modules, the installation inclination, and the movement trajectory of the sun.

[0031] Step 102: Generate a preliminary layout plan for each photovoltaic module based on the installable area location information and the layout parameters.

[0032] In the installation area, according to the set layout parameters, the preliminary layout plan of photovoltaic modules is automatically generated. This can be achieved by using computer algorithms or professional photovoltaic design software. According to the shape and size of the site, the photovoltaic modules are arranged as closely as possible to increase the installed capacity and power generation of the photovoltaic power station.

[0033] Use the automatic layout function in the software or the script you have written to run the automatic layout algorithm. On the premise of meeting the installation requirements, arrange as many photovoltaic modules as possible to increase the total power generation of the system; consider the shading effect of obstacles such as surrounding buildings and trees on photovoltaic modules, and optimize the layout position of the modules by calculating the sun's position and shadow trajectory to reduce shadow losses; ensure that the series and parallel connection method of the modules complies with electrical specifications to reduce line losses and fault risks; on the premise of ensuring performance, make the layout drawings aesthetically pleasing and facilitate later maintenance and repairs.

[0034] Step 103: Optimize the preliminary layout plan based on the photovoltaic module installation related information to determine a target layout plan.

[0035] Check whether the spacing between modules meets the requirements, whether there are potential shading problems, and whether the electrical connections are reasonable; according to the actual situation, the position, angle or number of modules can be manually adjusted to achieve the best design effect. At the same time, considering the feasibility and cost factors of construction, the layout plan is comprehensively evaluated. Optimization algorithms such as genetic algorithms and simulated annealing algorithms can be used to optimize the layout parameters of photovoltaic modules to maximize power generation efficiency.

[0036] Optionally, based on the preliminary layout plan and the meteorological information, the power generation of each photovoltaic module and the total power generation of the entire photovoltaic power station are calculated; a performance simulation is performed on the preliminary layout plan to obtain various performance indicators corresponding to the preliminary layout plan; based on the various performance indicators, the power generation of each photovoltaic module and the total power generation of the entire photovoltaic power station, the preliminary layout plan is optimized to obtain multiple optimized layout plans; the multiple optimized layout plans are screened to determine a target layout plan.

[0037] The performance of the initially generated layout scheme is simulated to calculate the power generation of each photovoltaic module and the total power generation of the entire photovoltaic power station. The photovoltaic system design software or professional simulation tools can be used to simulate and predict the performance of the photovoltaic power station based on local meteorological data (such as solar radiation intensity, temperature, wind speed, etc.) and the parameters of the photovoltaic modules. Evaluate other performance indicators of the layout scheme, such as system reliability, stability, maintenance cost, etc. For example, check whether the spacing between photovoltaic modules is sufficient to facilitate later maintenance and repair; analyze the performance of the photovoltaic power station under different weather conditions to ensure the stability of the system. According to the results of performance simulation and evaluation, the layout scheme is optimized. The layout parameters of photovoltaic modules, such as azimuth, inclination, spacing, etc., can be adjusted to improve the performance of the photovoltaic power station. Optimization algorithms, such as genetic algorithms and simulated annealing algorithms, can also be used to automatically optimize the layout scheme; multiple optimized layout schemes are screened, and the scheme with the best performance, lowest cost, and highest reliability is selected as the final layout scheme. According to the specific requirements and goals of the project, corresponding screening criteria and weights can be formulated to comprehensively evaluate and compare various schemes.

[0038] Optionally, based on the various performance indicators, the power generation of each photovoltaic module and the total power generation of the entire photovoltaic power station, the layout parameters of the photovoltaic modules are adjusted to obtain multiple optimized layout schemes, wherein the layout parameters include the azimuth angle, inclination angle of each photovoltaic module and the spacing between each photovoltaic module. Step 104 : generating a photovoltaic assembly layout drawing based on the target layout solution, a preset drawing template and the obtained description information corresponding to the photovoltaic assembly.

[0039] Draw the PV modules on the drawing template according to the final layout plan. You can use computer-aided design (CAD) software or professional PV design software to draw the PV module graphics on the drawing according to the actual size and position. Each PV module should be marked with its number, model, power and other information to facilitate identification by construction and maintenance personnel. The description information corresponding to the above PV modules can be the installation requirements, electrical connection methods, maintenance precautions, etc. of the PV modules.

[0040] Optionally, based on the target layout scheme and the obstacle information, photovoltaic components and obstacles are drawn on the preset drawing template to obtain an initial photovoltaic component arrangement drawing; based on the initial photovoltaic component arrangement drawing and the description information, the photovoltaic component arrangement drawing is generated.

[0041] As an example, select a suitable drawing template and add necessary annotations and instructions on the drawing, such as the installation requirements of PV modules, electrical connection methods, maintenance precautions, etc. The annotations and instructions should be concise and easy to understand, so that construction and maintenance personnel can operate according to the drawings.

[0042] Optionally, the obstacle information includes location information, graphic information and shape information of the obstacle, including: determining the shadow area information of the obstacle based on the movement trajectory of the sun and the location information of the obstacle; determining the boundary information of the obstacle based on the graphic information and the shape information; and drawing photovoltaic components and obstacles on the preset drawing template based on the target layout plan, the shadow area information and the boundary information to obtain an initial photovoltaic component layout drawing.

[0043] As an example, select a suitable drawing template, or create a custom drawing template according to the requirements of the project. The drawing template should contain basic information of the PV power station, such as the project name, location, construction unit, etc., as well as the scale, coordinate system, legend and other information of the drawing. Draw information such as obstacles, boundaries and shadows. Draw the graphics of obstacles on the drawing according to their actual position and shape, and mark their height, width and other information; draw the boundary line of the PV power station to clarify the scope of the project; draw the shadow area according to the movement of the sun and the position of the obstacles, so that construction personnel can understand the impact of shadows on PV modules.

[0044] Optionally, the key parameters of the photovoltaic assembly arrangement drawing are verified for accuracy to obtain an initial photovoltaic assembly arrangement drawing, wherein the key parameters include the size, spacing and angle of the photovoltaic assembly, and the power generation of each photovoltaic assembly and the total power generation of the entire photovoltaic power station; based on the relevant standard information obtained, the initial photovoltaic assembly arrangement drawing is safety checked to obtain a target photovoltaic assembly arrangement drawing, and the target photovoltaic assembly arrangement drawing is used as the photovoltaic assembly arrangement drawing.

[0045] After generating the layout drawings, key parameters should be verified for accuracy. For example, check whether the size, spacing, angle, etc. of the components are consistent with the actual requirements, and whether the power generation forecast is reasonable; verification can be carried out through field measurements or using simulation software to ensure the feasibility and reliability of the design. The layout design of photovoltaic components should comply with relevant national and industry specifications and standards, such as electrical safety specifications, building fire protection specifications, etc. Ensure that the design plan complies with the requirements of laws and regulations to ensure the safe operation of the system.
