The photovoltaic station may be composed of solar photovoltaic panels, which can convert solar radiation into electrical energy and then send the obtained electrical energy into the power grid for power supply.

[0029] Photovoltaic stations can be divided into different types according to their scale and layout, including but not limited to distributed photovoltaic stations, centralized photovoltaic stations and floating photovoltaic stations. Among them, distributed photovoltaic stations can be installed on the roof of a building or on an open space to provide power to local buildings or facilities; centralized photovoltaic stations are larger in scale and can be built on open ground or in areas such as deserts, using large areas of solar photovoltaic panels to generate electricity; floating photovoltaic stations may refer to photovoltaic power generation facilities built on the water surface, which use the water surface to dissipate heat and reduce the temperature of photovoltaic panels to improve power generation efficiency.

The capacity information may be the total installed capacity of a centralized photovoltaic station, or the installed capacity corresponding to each submodule in a distributed photovoltaic station. There is no limitation here. The installed capacity may be expressed in kilowatts (kW) or megawatts (MW). The capacity information may be used to measure the power generation capacity of a photovoltaic station. The larger the capacity information, the stronger the photovoltaic station's ability to generate electricity. The capacity information may also be determined according to actual needs, and there is no limitation here.

[0031] The above-mentioned preset time period may refer to a preset time period for obtaining photovoltaic station output information. For example, the preset time period may be one hour, six hours, one day, one month, etc. The preset time period may be determined according to actual needs and is not limited here.

[0032] The above-mentioned weather type may refer to the classification of weather conditions corresponding to a preset time period pre-classified by the user. The weather type may include but is not limited to sunny, cloudy, overcast, rainy and other weather types. Sunny, cloudy, overcast, rainy, etc. may be further divided into multiple levels of weather types according to actual needs. The division of weather types and specific types can be determined according to actual needs and are not limited here.

[0033] In an optional embodiment, the output information, capacity information and weather information of the photovoltaic station can be obtained. The output information can be used to characterize the actual power generation of the photovoltaic station within a preset time period, and can be used to determine the operating status of the photovoltaic station; the capacity information can refer to the installed capacity of the photovoltaic station, which can be the size of the total installed capacity of the photovoltaic components, and can be used to determine the power generation potential and performance of the photovoltaic station, that is, the expected power generation; the weather information can refer to the weather type corresponding to the photovoltaic station within a preset time period, which can include sunny, cloudy, overcast, rainy, etc.; obtaining the output information can be achieved by monitoring the real-time monitoring system such as the inverter data and meter data of the photovoltaic station, and the output information can reflect The actual power generation and power generation of photovoltaic stations in different time periods can determine the operating status and performance of photovoltaic stations. Capacity information can be obtained by understanding the total installed capacity of photovoltaic modules and considering factors such as the layout and module configuration of photovoltaic stations to determine the expected power generation capacity of photovoltaic stations. Weather information can be obtained through meteorological stations and weather forecasts. Weather information can provide weather conditions of photovoltaic stations in a preset time period, including parameters such as temperature, wind speed, and light intensity. By comprehensively analyzing output information, capacity information and weather information, the operating status and power generation performance of photovoltaic stations can be determined more accurately, providing an important basis for the operation and maintenance management and optimization of photovoltaic stations.

[0034] Step S104: determining a target ratio mapping relationship from preset ratio mapping relationships based on weather information.

[0035] Among them, the preset ratio mapping relationship is used to represent the mapping relationship between the target ratio and the output rationality of the photovoltaic station under different weather types. The target ratio is used to represent the ratio between the output and capacity of the photovoltaic station. The output rationality is used to characterize the degree to which the actual output of the photovoltaic station meets the expected output.

[0036] The above-mentioned preset ratio mapping relationship may include a plurality of ratio mapping relationships corresponding to different weather types, and the ratio mapping relationship corresponding to each weather type may be different.

[0037] In an optional embodiment, the operating status of the photovoltaic station can be determined based on weather information. Taking into account the uncertainty of the weather, a preset ratio mapping relationship can be established to represent the relationship between the target ratio and the actual output under different weather types. The preset ratio mapping relationship can be obtained through historical data and simulation analysis, and the ratio of the average output to the capacity of the photovoltaic station under different weather conditions can be considered. By using weather information, the corresponding target ratio mapping relationship under the current weather type can be determined from the relationship between the expected output and the actual output under different weather types, thereby eliminating the interference of weather information on the determination of the operating status of the photovoltaic station and avoiding the influence of factors unrelated to the photovoltaic station itself on the operating status of the photovoltaic station. The influence of weather conditions is determined. When the actual weather conditions change, the target ratio can be determined according to the preset ratio mapping relationship, so as to determine the rationality of the output of the photovoltaic station. The target ratio can be the ratio between the output and capacity of the photovoltaic station, which can be used to determine the operating status of the photovoltaic station; the output rationality can characterize whether the actual output of the photovoltaic station meets the expected output, that is, the degree of deviation between the actual output and the expected output. By establishing a preset ratio mapping relationship and determining the target ratio mapping relationship, the photovoltaic station operation and maintenance personnel can better monitor and determine the operating status of the photovoltaic station, discover problems in time and take corresponding measures to adjust and optimize, thereby improving the power generation efficiency and economic benefits of the photovoltaic station.

[0038] Step S106, determining the rationality of the target output of the photovoltaic station based on the mapping relationship among the output information, the capacity information and the target ratio.

[0039] In an optional embodiment, the power generation, power output, operating efficiency and other aspects of the photovoltaic station can be monitored and determined to ensure the normal operation of the photovoltaic station and achieve the expected power generation effect. The analysis of the output information, capacity information and target ratio mapping relationship can help operation and maintenance personnel determine the power generation efficiency and operating status of the photovoltaic station. Based on the actual power generation and power output data of the photovoltaic station in the output information, the monitoring equipment can collect and record the information in real time. By comparing and analyzing the output information and capacity information, the actual power generation efficiency and operating status of the photovoltaic station can be obtained. The target ratio mapping relationship can be determined based on the design parameters and expected goals of the photovoltaic station. The theoretical proportional relationship between output and capacity can be determined. By comparing the proportional relationship between the actual output and the target output, it can be determined whether the power generation efficiency of the photovoltaic station reaches the expected goal and the rationality of the output can be determined.

[0040] When determining the rationality of the target output of a photovoltaic station, the following steps can be taken: collect and analyze the output information and capacity information of the photovoltaic station, including actual power generation, power output, installed capacity and other data; determine the target proportion mapping relationship according to the design parameters and expected goals of the photovoltaic station; compare the proportional relationship between the actual output and the target output, determine the power generation efficiency and operating status of the photovoltaic station, and obtain the rationality of the target output; according to the rationality of the target output, adjust and optimize the operating status of the photovoltaic station to improve the power generation efficiency and achieve the expected goals. The above steps can help operation and maintenance personnel to promptly discover problems and deficiencies in the photovoltaic station, take timely measures to repair and improve them, and ensure the normal operation and power generation efficiency of the photovoltaic station.

[0041] Step S108, determining the operating status of the photovoltaic station based on the target output rationality.

[0042] In an optional embodiment, the target output rationality of the photovoltaic station may be positively correlated with the operating status of the photovoltaic station. Specifically, the target output rationality of the photovoltaic station may be linearly positively correlated, nonlinearly positively correlated, mapped positively correlated, etc. with the operating status of the photovoltaic station. It can be determined according to actual needs and is not limited here. Determining the operating status of the photovoltaic station based on the target output rationality may include the following steps: monitoring the actual power generation of the photovoltaic power station, comparing it with the expected target output, and determining the operating status of the photovoltaic power station. If the actual power generation is significantly lower than the target output, there may be equipment failure, shadow obstruction or other problems that need to be dealt with in a timely manner; by analyzing the photovoltaic power station The power generation efficiency, including conversion efficiency, loss rate and other indicators, is used to determine the power generation performance of the photovoltaic power station. If the power generation efficiency is lower than expected, equipment maintenance or optimization of the operation strategy may be required; key equipment of the photovoltaic power station, including photovoltaic modules, inverters, brackets, etc., should be regularly inspected to ensure the normal operation of the equipment and to promptly discover and deal with potential problems; the operation strategy of the photovoltaic power station should be adjusted according to actual conditions, including cleaning modules, adjusting the power generation angle, optimizing shadow management, etc., to improve power generation efficiency and reduce operation and maintenance costs. Through the above steps, the operation status of the photovoltaic site can be fully determined, problems can be discovered and solved in a timely manner, and the photovoltaic power station can be ensured to generate electricity stably and efficiently and achieve the expected power generation target.

[0043] In an embodiment of the present invention, a method for determining the operating status of a photovoltaic station is provided, including: obtaining output information, capacity information and weather information of the photovoltaic station, wherein the output information is used to characterize the actual power generation of the photovoltaic station within a preset time period, and the weather information is used to characterize the weather type corresponding to the photovoltaic station within the preset time period; based on the weather information, determining a target proportion mapping relationship from a preset proportion mapping relationship, wherein the preset proportion mapping relationship is used to represent a mapping relationship between a target proportion and an output rationality of the photovoltaic station under different weather types, the target proportion is used to represent the ratio between the output and capacity of the photovoltaic station, and the output rationality is used to characterize the degree to which the actual output of the photovoltaic station meets the expected output; based on the output information, capacity information and target proportion mapping relationship, determining the target output rationality of the photovoltaic station; based on the target output rationality, determining the operating status of the photovoltaic station. It is easy to notice that the present application obtains the output information, capacity information and weather information of the photovoltaic station, and can determine the actual power generation situation of the photovoltaic station within a preset time period based on the output information. By using the weather information, the corresponding target proportional mapping relationship under the current weather type can be determined from the relationship between the expected output and the actual output under different weather types, thereby eliminating the interference of weather information on the determination of the operating status of the photovoltaic station. Through the capacity information, the different conditions of each photovoltaic station itself are fully taken into account, so that the rationality of the target output of the photovoltaic station can be determined, thereby more comprehensively determining the operating status of the photovoltaic station. The present application is based on the method of multi-faceted information and proportional mapping relationship, which can improve the accuracy and efficiency of the operating status of the photovoltaic station, thereby solving the technical problems of low accuracy and efficiency in determining the operating status of the photovoltaic station in the related technology.

[0044] Optionally, based on the output information, capacity information and target ratio mapping relationship, determining the target output rationality of the photovoltaic station includes: determining the ratio of the output information and the capacity information to obtain a first ratio; mapping the first ratio based on the target ratio mapping relationship to obtain the target output rationality.

[0045] In an optional embodiment, the ratio of the output information and the capacity information, i.e., the first ratio, is determined, so that the relationship between the actual output power of the photovoltaic station and the theoretical maximum output power can be determined, thereby determining and monitoring the operation status of the photovoltaic station. The first ratio can reflect the actual power generation efficiency and system operation status of the photovoltaic station. The first ratio is mapped based on the target ratio mapping relationship, that is, the ratio of the actual output information and the capacity information is compared with the pre-set target ratio, thereby determining the rationality of the output of the photovoltaic station. By setting a reasonable target ratio, it can help operation and maintenance personnel to better understand the power generation situation of the photovoltaic station and timely To discover and solve problems that arise, in actual operation, the monitoring system can be used to collect the output information and capacity information of the photovoltaic station in real time, calculate the first ratio, and then compare it with the target ratio to obtain the target output rationality. If the target output rationality is high, it means that the photovoltaic station is in good operating condition; conversely, if the target output rationality is low, it is necessary to further analyze the cause of the problem, and take corresponding measures to adjust and improve it. Determine the ratio of output information and capacity information, and determine it based on the target ratio mapping relationship, which can help improve the power generation efficiency and operation reliability of the photovoltaic station and ensure its long-term stable operation.

[0046] Optionally, obtaining output information of a photovoltaic station includes: obtaining real-time power generation information of the photovoltaic station within a preset time period; and integrating the real-time power generation information based on the preset time period to obtain output information.

[0047] In an optional embodiment, obtaining the output information of the photovoltaic station may include: obtaining the real-time power generation information of the photovoltaic station within a preset time period, and integrating the real-time power generation information based on the preset time period to obtain the output information. Specifically, obtaining the real-time power generation information of the photovoltaic station within the preset time period may be achieved through a monitoring system. The monitoring system may be installed in the control center of the photovoltaic station, and may monitor the power generation, voltage, current and other parameters of the photovoltaic components in real time. Through the monitoring system, the operation and maintenance personnel may understand the power generation situation of the photovoltaic station at any time; integrating the real-time power generation information based on the preset time period may obtain the output information of the photovoltaic station, which may be achieved through data processing software. The monitored real-time power generation information may be integrated and calculated according to the time period to obtain the total power generation of the photovoltaic station within the time period. This may help the operation and maintenance personnel understand the power generation efficiency of the photovoltaic station, determine the operating status of the photovoltaic station, and perform further optimization and adjustment. By monitoring and analyzing the output information of the photovoltaic station, important reference data may be provided to the operation and maintenance personnel to better manage and maintain the photovoltaic station.

[0048] Optionally, obtaining weather information of the photovoltaic station includes: obtaining solar radiation intensity, temperature information and air dust concentration of the area where the photovoltaic station is located within a preset time period; and determining weather information based on the solar radiation intensity, temperature information and air dust concentration.

[0049] In an optional embodiment, weather information of a photovoltaic station is obtained, which may include but is not limited to parameters such as solar radiation intensity, temperature, and air dust concentration. The above parameters may affect the power generation efficiency and operation safety of the photovoltaic station. The solar radiation intensity of the area where the photovoltaic station is located within a preset time period may be obtained. The solar radiation intensity may refer to the energy radiated by solar energy to the ground, which may affect the operation status of photovoltaic panels. By measuring the solar radiation intensity, the power generation and power generation efficiency of the photovoltaic station may be predicted, thereby reasonably arranging the power supply. Temperature information may also affect the operation status of photovoltaic panels. Photovoltaic panels have higher power generation efficiency at lower temperatures. The power generation efficiency will decrease at higher temperatures. Timely acquisition of temperature information around photovoltaic stations can help optimize the power generation efficiency of photovoltaic stations. In addition, the concentration of air dust can also affect the operation of photovoltaic panels. High concentrations of air dust will affect the penetration of sunlight and reduce the intensity of solar radiation, thereby affecting the power generation efficiency of photovoltaic stations. Monitoring the concentration of air dust and timely cleaning the surface of photovoltaic panels can improve the power generation efficiency of photovoltaic stations. Combining parameters such as solar radiation intensity, temperature information and air dust concentration can determine the weather information of the area where the photovoltaic station is located. Based on the weather information, the operation status of the photovoltaic station under different weather types can be determined.

[0050] Optionally, the target ratio mapping relationship includes at least: a first ratio mapping relationship and a second ratio mapping relationship, wherein the first ratio mapping relationship is used to represent the mapping relationship between the first ratio and the first output rationality, and the second ratio mapping relationship is used to represent the mapping relationship between the second ratio and the second output rationality, the first ratio is greater than the second ratio, and the first output rationality is greater than the second output rationality.

[0051] In an optional embodiment, the target proportion mapping relationship can determine the rationality of different outputs through proportion mapping. The first proportion mapping relationship is used to represent the mapping relationship between the first proportion and the first output rationality, and the second proportion mapping relationship is used to represent the mapping relationship between the second proportion and the second output rationality. The first proportion can be set to be greater than the second proportion, and the first output rationality can be greater than the second output rationality. In practical applications, the first proportion and the second proportion can refer to the ratio of the power generation of the photovoltaic station to the theoretical maximum power generation. The first output rationality and the second output rationality can represent the ratio of the actual power generation to the theoretical maximum power generation, that is, the target proportion and the output rationality can be positively correlated. By determining the mapping relationship between these two sets of proportions, it can help operators better monitor the operating status of the photovoltaic station, promptly discover and solve problems such as low or abnormal power generation efficiency. The establishment and application of the target proportion mapping relationship can provide an effective reference basis for the operation and management of the photovoltaic station.

[0052] Optionally, based on the target output rationality, the operating status of the photovoltaic station is determined, including: when the target output rationality is greater than a preset rationality threshold, determining that the operating status is that the photovoltaic station is in a normal operating state; when the target output rationality is less than or equal to the preset rationality threshold, determining that the operating status is that the photovoltaic station is in an abnormal operating state, and outputting a prompt message, wherein the prompt message is used to remind to perform maintenance on the photovoltaic station.

[0053] The above-mentioned preset rationality threshold may refer to a threshold preset by the user to measure the rationality of the target output, for example, it may be 0.8, 0.75, etc. The preset rationality threshold may be determined according to actual needs and is not limited here.

[0054] In an optional embodiment, the actual operation of the station can be determined by monitoring the power generation output of the photovoltaic components. The target output rationality can represent the ratio between the actual power generation output and the expected power generation output, which is used to measure whether the operation of the photovoltaic station is normal. When determining the operation of the photovoltaic station, a preset rationality threshold can be set. When the target output rationality is greater than the preset rationality threshold, it means that the actual power generation output of the photovoltaic station is basically consistent with the expected power generation output, and the station is in a normal operating state, and no special maintenance measures are required; when the target output rationality is less than or equal to the preset rationality threshold, it can be said that the actual power generation output of the photovoltaic station is lower than expected, and there may be some abnormal conditions, such as photovoltaic components being blocked by shadows, component aging, system failure, etc. In this case, it is necessary to determine that the photovoltaic station is in an abnormal operating state and output prompt information in time to remind the operation and maintenance personnel to maintain and repair the photovoltaic station. Through the above steps, the operation of the photovoltaic station can be effectively monitored, problems can be discovered in time and corresponding measures can be taken to ensure the long-term stable operation and power generation efficiency of the photovoltaic station.
