Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic power generation, and in particular relates to a mountain photovoltaic quick connection installation and error adjustment method. Background Art

[0002] Mountain photovoltaic installation is one of the main ways for the country to promote new energy construction. However, during the installation process, there are often factors such as topography, construction procedures, etc. that restrict the speed of mountain photovoltaic installation, resulting in large-scale secondary drilling and rework of the brackets. This not only causes delays in the construction period, but also affects the stability and safety of the photovoltaic brackets. Therefore, there is a need for methods to increase the speed of mountain photovoltaic installation and increase safety.

[0003] The patent application document with announcement number CN116862711A discloses a digital twin system and method for mountain photovoltaic installation operations. It optimizes the operation process through the twin decision layer, interactively drives each operating equipment in the physical entity layer and its corresponding twin model in the twin virtual layer, and completes the information management and automated operations of mountain photovoltaic transportation and installation, so as to realize intelligent management and control of the mountain photovoltaic installation operation process and visual supervision of the operation site, improve the efficiency of mountain photovoltaic installation operations, and enhance the technical level of mountain photovoltaic power station construction.

[0004] The patent application document with announcement number CN115345437A discloses an artificial intelligence-based photovoltaic error assessment method and system. Based on the time and node at which the target photovoltaic loss data occurs in the real-time photovoltaic data, and at least one of the error assessment results of the target photovoltaic loss data meets the set conditions, the accurate loss situation of the target photovoltaic loss data is determined, thereby being able to reliably generate photovoltaic error loss results. In this way, the credibility of the photovoltaic error loss results can be effectively improved.

[0005] The patent application document with announcement number CN109145503A discloses a high-precision dynamic modeling method for photovoltaic power station clusters. The hybrid modeling framework significantly improves the accuracy of the equivalent model while retaining the advantages of the cluster equivalent model such as low order and low simulation time. This file framework can be expanded and applied to other problems such as the modeling of high-penetration renewable energy distribution networks.

[0006] The patent application document with announcement number CN222525807U discloses a special platform rack for mountain photovoltaic installation and a mountain photovoltaic installation system. In this special platform rack, the first platform pole and the second platform pole are detachably connected to the ridge pole, which achieves the effect of simple assembly and disassembly of the device and effectively improves the installation efficiency. By setting a limiter and a movable baffle, the ridge pole is firmly connected to the column at the construction site to prevent the first platform pole, the second platform pole and the ridge pole from tipping over. Therefore, the device can prevent tipping over, does not require human supervision when in use, and is highly safe.

[0007] Based on the comparison of existing technologies, it was found that existing technologies mainly use artificial intelligence, digital twins, big data, etc. to analyze photovoltaic installation errors, and mainly design photovoltaic installation platforms and photovoltaic installation systems to improve installation speed and ensure safety. However, the above technologies are not easy to operate during actual on-site construction, and fail to solve or reduce the problems of large-scale secondary openings, process connection, and bracket bearing capacity stability in the bracket installation process from the source.
