Description

Technical Field

[0001] This invention belongs to the field of energy management technology, and specifically relates to a photovoltaic power plant management system. Background Technology

[0002] Photovoltaic (PV) power generation is a technology that directly converts light energy into electrical energy using the photovoltaic effect at semiconductor interfaces. It mainly consists of photovoltaic panels and inverters. Solar panels, connected in series and encapsulated for protection, form large-area solar cell modules to generate electricity. In PV power generation, the amount of sunlight received by the photovoltaic panels primarily determines the power generation capacity. In other words, the stability of PV power output is affected by environmental factors such as sunlight intensity, ambient temperature, and weather. For large-area PV power plants with long operating cycles, it is necessary to clean the surface of the photovoltaic panels to ensure they are clean and can better receive sunlight, thus guaranteeing their power generation capacity. Therefore, it is necessary to research and develop a PV power plant management system that can ensure the cleanliness of the photovoltaic panel surface, enhance the panels' ability to receive sunlight, and facilitate maintenance. Summary of the Invention

[0003] To address the aforementioned technical problems, the present invention aims to provide a photovoltaic power station management system that can clean the surface of photovoltaic panels and is easy to maintain.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] The photovoltaic power plant management system includes a photovoltaic panel array, a photovoltaic panel management module, an energy storage array, an energy storage management module, a control center, and an inspection management module. The photovoltaic panel array is connected to the photovoltaic panel management module, the energy storage array is connected to the energy storage management module, and the energy storage management module, photovoltaic panel management module, and inspection management module are connected to the control center.

[0006] A photovoltaic array consists of several photovoltaic panels arranged in a square array, used to receive sunlight and convert light energy into electrical energy;

[0007] The energy storage array consists of several energy storage cabinets arranged on the same side of the photovoltaic panel array, used to store the electrical energy generated by the photovoltaic panel array; each energy storage cabinet is equipped with energy storage battery packs arranged in a spaced manner.

[0008] The photovoltaic panel management module includes a cleaning management module for controlling the reciprocating cleaning of the photovoltaic panel surface on each photovoltaic panel and an image management module for acquiring images of the photovoltaic panel surface on each photovoltaic panel. During the cleaning operation of the cleaning management module on the photovoltaic panel surface, the image management module acquires images of the photovoltaic panel surface after cleaning.

[0009] The energy storage management module is connected to each energy storage battery pack and is used to manage the charging and discharging of the energy storage battery pack, as well as monitor the remaining power of each energy storage battery pack and the charging and discharging time during the battery's life cycle.

[0010] The control center is used for information exchange between the energy storage management module and the photovoltaic panel management module, as well as to receive external instructions and manage and operate the energy storage management module and the photovoltaic panel management module.

[0011] The inspection management module receives instructions from the control center and executes inspection tasks on the photovoltaic array and / or energy storage array.

[0012] As a further implementation, the cleaning management module includes an online weather acquisition module for obtaining weather forecasts; the cleaning management module manages the cleaning modes for the photovoltaic panel surface, including:

[0013] When the daily light conditions reach the set threshold, perform at least one reciprocating cleaning of the photovoltaic panel surface regularly.

[0014] When sandstorms or smog occur, and the sunlight conditions are below the set threshold, a cleaning action will be performed on the surface of the photovoltaic panels, and the surface of the photovoltaic panels will be cleaned at least once.

[0015] When the rainfall reaches the set threshold, the cleaning management module issues a cleaning command to initiate a cleaning action on the surface of the photovoltaic panel, performing at least two round trips to clean the surface of the photovoltaic panel.

[0016] The photovoltaic panel surface is cleaned using a reciprocating cleaning structure that spans across the panel surface.

[0017] In a further embodiment, the image management module is connected to several image acquisition devices, which are positioned on the movable cleaning structure and move with it.

[0018] During a single cleaning cycle of the photovoltaic panel surface, the image acquisition device captures multiple images of the cleaned photovoltaic panel surface, and the image information obtained from these multiple image acquisitions is transmitted to the image management module.

[0019] The image management module acquires image information from each image acquisition device, compares the acquired image information with the set image information, and transmits the comparison result to the control center.

[0020] As a further implementation, the control center signal transmission is connected to a cloud server, and the cloud server signal transmission is connected to a control terminal.

[0021] When the image management module finds that the image information does not match the set image information, it sends an image anomaly message to the control terminal via the cloud server. The control terminal then displays the image information from the image anomaly message for the user to view.

[0022] When the image management module compares the image information with the set image information, it transmits the comparison result to the cloud server for storage.

[0023] As a further implementation, the patrol management module is signal-connected to at least one patrol drone;

[0024] When the user of the control terminal needs to reconfirm the abnormal image information, the coordinates of the photovoltaic panel that generated the abnormal image information are obtained through the control terminal and sent to the inspection management module. The inspection management module sends an instruction to the inspection drone to perform image acquisition on the surface of the photovoltaic panel at that coordinate location. The inspection drone then feeds back the image information of the photovoltaic panel surface at the specified coordinates to the control terminal.

[0025] As a further implementation, the patrol drone flies toward the target point according to the received coordinate position of the photovoltaic panel and collects images of the surface of the photovoltaic panel at that coordinate position. The collected image information includes at least five images from the front, back, left, right and directly above the plane where the surface of the photovoltaic panel is located.

[0026] Among them, the image information acquisition angles for the front, back, left, and right perspectives are formed at 45° angles with the plane on which the photovoltaic panel surface is located;

[0027] When the control terminal sends multiple photovoltaic panel coordinate location image information acquisition commands to the inspection drone through the inspection management module, the inspection management module calculates the distance between each photovoltaic panel coordinate location and the inspection drone, and sends them to the inspection drone in order of increasing distance. The inspection drone then executes the image acquisition task in order of increasing distance.

[0028] As a further implementation, when the energy storage management module charges and discharges the energy storage battery pack, during the charging process, the energy storage battery packs are arranged from low to high according to their remaining power. The charging starts with the energy storage battery packs with low remaining power and is charged to the set power threshold in one go. Then, the energy storage battery packs with low remaining power are selected for charging in turn.

[0029] During the discharge process of the energy storage battery pack, the remaining power of each energy storage battery pack is obtained, a batch of energy storage battery packs with remaining power within a selected range are selected, and the number of charge and discharge cycles of the energy storage battery packs is retrieved. The discharge is then selected from low to high charge and discharge cycles. When the number of charge and discharge cycles is the same, the energy storage battery pack with more remaining power is given priority for discharge.

[0030] By adopting the above technical solution, the beneficial effects of the present invention compared with the prior art are as follows:

[0031] 1. This invention can automatically control the cleaning structure to repeatedly clean the surface of each photovoltaic panel through the cleaning management module, so as to ensure the cleanliness of the photovoltaic panel surface and avoid the photovoltaic panel's ability to receive light due to foreign objects covering the photovoltaic panel surface, thereby ensuring the photovoltaic power generation capacity.

[0032] 2. This invention can monitor the presence of foreign objects on the surface of photovoltaic panels in real time through an image acquisition device. In conjunction with the cleaning management module, it can better and more accurately clean the surface of photovoltaic panels. The image acquisition device can also detect whether there is any damage to the surface of photovoltaic panels, thereby improving the management capabilities of photovoltaic panels.

[0033] 3. The present invention can obtain the remaining power, number of charge and discharge cycles, and charge and discharge duration of the energy storage battery pack through the energy storage management module, so as to understand the charging and discharging status of each energy storage battery pack and to better maintain the energy storage battery pack.

[0034] 4. This invention, by placing the image acquisition device on a mobile cleaning structure, can flexibly acquire images of the photovoltaic panel surface. Furthermore, by using a patrol drone controlled by the patrol management module, it can obtain real-time information on the photovoltaic array and energy storage array, thereby improving the management capabilities and efficiency of the photovoltaic power station.

[0039] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figure 1 , 2As shown in Figures 3 and 4, the photovoltaic power station management system includes a photovoltaic panel array, a photovoltaic panel management module, an energy storage array, an energy storage management module, a control center, and an inspection management module. The photovoltaic panel array is connected to the photovoltaic panel management module, the energy storage array is connected to the energy storage management module, and the energy storage management module, photovoltaic panel management module, and inspection management module are connected to the control center. The connection method here can be wireless or wired, depending on the actual modules.

[0041] A photovoltaic array consists of several photovoltaic panels arranged in a square array to receive sunlight and convert light energy into electrical energy. The photovoltaic panels are fixed solar panels with an inclined angle. The solar panels in the array are arranged at equal intervals in the row direction and at equal intervals in the column direction to facilitate the construction of a planar coordinate system. Each photovoltaic panel in the array is assigned a corresponding coordinate position, and the origin of the constructed planar coordinate system coincides with the origin of the three-dimensional coordinate system of the inspection drone.

[0042] The energy storage array consists of several energy storage cabinets arranged on the same side of the photovoltaic panel array. The energy storage cabinets are arranged at a certain safe distance to store the electrical energy generated by the photovoltaic panel array. Each energy storage cabinet contains a battery pack arranged at intervals. The arrangement of the energy storage cabinets in the energy storage array is also in the three-dimensional coordinate system of the inspection drone, that is, the energy storage cabinets are in the planned inspection path of the inspection drone and are within the inspection range of the drone.

[0043] The photovoltaic panel management module includes a cleaning management module for controlling the reciprocating cleaning of the photovoltaic panel surface on each panel and an image management module for acquiring images of each photovoltaic panel surface. During the cleaning operation of the cleaning management module, the image management module acquires images of the cleaned photovoltaic panel surface. A movable cleaning structure is set on each photovoltaic panel support, which uses a brush roller to move across the photovoltaic panel surface for cleaning. The brush roller is mounted on a movable horizontal plate, which reciprocates across the photovoltaic panel surface. An image acquisition device, which is a camera with photo and video recording functions, is installed on the movable horizontal plate. A rotary motor is installed on the movable horizontal plate, and the camera is mounted on the rotating end of the rotary motor, so that the camera can rotate to face the cleaned photovoltaic panel surface for better image acquisition.

[0044] The energy storage management module is connected to each energy storage battery pack and is used to manage the charging and discharging of the energy storage battery packs, as well as monitor the remaining power and charging and discharging duration of each energy storage battery pack within its service life. The energy storage management module includes a remaining power detection module (battery power detection module, used to monitor the real-time power in the battery pack), a charging and discharging control module, and a charging and discharging timing module to obtain the charging and discharging duration of each energy storage battery pack. When the total charging and discharging duration reaches the set duration, a replacement warning is generated and reported to the control terminal. The charging and discharging control module is used to control the charging and discharging of the energy storage battery packs and to obtain the charging and discharging count module from the charging and discharging control module to understand the charging and discharging status of each energy storage battery pack.

[0045] The control center is used for information exchange between the energy storage management module and the photovoltaic panel management module, as well as to receive external instructions and manage and operate the energy storage management module and the photovoltaic panel management module. In other words, the control center can switch between charging the electricity generated by the photovoltaic panel and the energy storage battery pack, and can also manage the discharge of the electricity in the energy storage battery pack.

[0046] The inspection management module receives instructions from the control center to perform inspection tasks on photovoltaic arrays and / or energy storage arrays. The inspection management module is mainly used to manage inspection drones to obtain the on-site conditions of photovoltaic arrays and energy storage arrays.

[0047] The cleaning management module includes an online weather forecast acquisition module to monitor weather conditions and assist in its operation and management. The cleaning management module manages the cleaning modes for photovoltaic panel surfaces as follows:

[0048] When the daily light conditions reach the set threshold, the photovoltaic panel surface is cleaned at least once a week. Specifically, a light sensor is installed on the photovoltaic array to collect real-time light data. When the collected light is within the set threshold range, the cleaning management module controls the mobile cleaning structure to perform regular cleaning of the photovoltaic panel surface, such as once a week.

[0049] When sandstorms or smog occur and the sunlight conditions are below the set threshold, a cleaning action is performed on the surface of the photovoltaic panels, cleaning the surface of the photovoltaic panels at least once. A visibility meter is installed on the photovoltaic panel array to detect the local air environment. When the visibility is below the set threshold, the cleaning work on the surface of the photovoltaic panels can be started to reduce the accumulation of dust in the air on the surface of the photovoltaic panels. Of course, the cleaning work on the surface of the photovoltaic panels can also be started when the air visibility monitored by the visibility meter recovers to the set threshold.

[0050] When rainfall reaches a set threshold, the cleaning management module issues a cleaning command to initiate a cleaning process on the photovoltaic panel surface, performing at least two reciprocating cleaning cycles. This mode utilizes a rain sensor on-site to monitor rainfall. The rain helps the brush rollers to perform a deeper cleaning of the photovoltaic panel surface, effectively removing dust. However, if both the visibility meter and rain sensor readings fall below their respective set thresholds simultaneously (e.g., raindrops affecting visibility), the system will operate according to the mode where cleaning occurs only when the rainfall reaches the set threshold.

[0051] The image management module is connected to several image acquisition devices, which move along with the mobile cleaning structure. Each image acquisition device collects image information corresponding to the surface of a photovoltaic panel, and each image acquisition device has a number that corresponds one-to-one with the coordinate position of the photovoltaic panel. That is, once the coordinate position of the photovoltaic panel is known, the number of the image acquisition device can be known, or the coordinate position of the photovoltaic panel can be obtained by obtaining the number of the image acquisition device, thereby ensuring the correspondence between the image acquisition device and the photovoltaic panel.

[0052] During a single reciprocating cleaning task on the surface of a photovoltaic panel, the image acquisition device captures multiple images of the cleaned panel. The image information obtained from these multiple acquisitions is transmitted to the graphics management module. For example, during a single reciprocating movement of a mobile cleaning structure, the image acquisition device captures an image of the cleaned photovoltaic panel surface during its first movement. When the mobile cleaning structure returns to its starting position, the image acquisition device captures another image of the cleaned photovoltaic panel surface. The image acquisition device can capture the image information of the entire photovoltaic panel surface in a single operation, such as taking a picture after cleaning the entire photovoltaic panel surface once, or it can acquire the image information through multiple images, such as taking a picture at the middle of the photovoltaic panel surface. These multiple images constitute the image information of the entire photovoltaic panel surface. The image management module obtains the image information from each image acquisition device, compares the obtained image information with the set image information, and transmits the comparison result to the control center. The comparison here involves comparing the acquired photovoltaic panel surface image information with the initial photovoltaic panel surface image information obtained by pre-taking photos. When there are foreign objects, cracks, or other abnormalities on the photovoltaic panel surface, the comparison can generate abnormal image information of the photovoltaic panel surface and send it to the control center for processing.

[0053] The control center's signal transmission is connected to a cloud server. Data in the control center interacts and transmits signals with the cloud server. The cloud server's signal transmission is connected to a control terminal, which can be a computer terminal or a handheld terminal. The cloud server and the control terminal can interact. When the image management module's comparison of image information does not match the set image information, it sends an image anomaly information to the control terminal through the cloud server. The control terminal displays the image information in the image anomaly information for the user to view and issue corresponding instructions to the control center, which then dispatches subsequent tasks for execution. When the image management module's comparison of image information matches the set image information, it transmits the comparison result to the cloud server for storage for later review. The stored matching image information can be automatically deleted after a certain period of time to reduce the occupation of cloud server storage space.

[0054] The inspection management module is connected to at least one inspection drone, which is equipped with high-definition photography capabilities. The number of inspection drones is configured according to the size of the photovoltaic panel array. The participation of inspection drones reduces the need for personnel to inspect the photovoltaic panels on-site and improves work efficiency.

[0055] When the user of the control terminal needs to reconfirm the abnormal image information, the coordinates of the photovoltaic panel that caused the abnormal image information are obtained through the control terminal, and the coordinates are sent to the inspection management module through the cloud server and the control center. The inspection management module sends an instruction to the inspection drone to collect images of the photovoltaic panel surface at the coordinates. The inspection drone then flies to the corresponding photovoltaic panel according to the coordinates and collects surface images. The inspection drone then feeds back the photovoltaic panel surface image information at the specified coordinates to the control terminal through the inspection management module, the control center, and the cloud server. The user of the control terminal can then obtain clearer and more numerous images of the photovoltaic panel surface to judge the surface condition of the photovoltaic panel. When it is determined that there are foreign objects that are difficult to clean, the corresponding cleaning structure on the photovoltaic panel can be operated independently. When it is determined that there is damage to the photovoltaic panel surface, maintenance personnel need to be notified to carry out maintenance on site. This allows for real-time monitoring of the photovoltaic panel surface condition, thereby ensuring the stable power generation capacity of the photovoltaic panel.

[0056] When the patrol drone receives a flight data collection mission, the patrol management module obtains the drone's battery level and real-time location, calculates the distance between the real-time location and the received flight coordinates, and measures whether the battery level can sustain the mission until completion. This battery level calculation also includes determining whether the drone can return to its initial takeoff point after reaching the flight coordinates. If the drone's battery level is sufficient to sustain the mission, it proceeds. If the drone's battery level is insufficient to continue, the patrol management module sends the drone's real-time battery level to the control terminal, indicating that the battery is too low to continue the flight mission. Simultaneously, it manages the drone to return to its initial takeoff point for charging and feeds back the pre-charging time to the control terminal.

[0057] The inspection drone flies towards the target point based on the received coordinates of the photovoltaic panel and collects images of the photovoltaic panel surface at that coordinate location. The collected images include at least five images from the front, back, left, right, and directly above the plane where the photovoltaic panel surface is located. The front, back, left, and right images are acquired at a 45° angle to the plane where the photovoltaic panel surface is located. By acquiring images of the photovoltaic panel surface from multiple angles, the condition of the photovoltaic panel surface can be observed more clearly, making the image data acquisition more accurate.

[0058] In addition, when the control terminal sends multiple photovoltaic panel coordinate location image information acquisition commands to the inspection drone through the inspection management module, the inspection management module calculates the distance between each photovoltaic panel coordinate location and the inspection drone, and sends them to the inspection drone in order of increasing distance. The inspection drone then executes the image acquisition task in order of increasing distance to optimize the execution path of the inspection drone. During this process, the power consumption of the inspection drone should also be taken into account, that is, the power consumption calculation method mentioned above should be used to calculate the power consumption to ensure that the inspection drone can stably execute the image acquisition task.

[0059] When the energy storage management module charges and discharges the energy storage battery pack, in order to ensure a relatively balanced number of charge and discharge cycles and maximize the overall usage time of the energy storage battery pack, the order of charging and discharging can be further planned. For example, during the charging process, the energy storage battery packs are arranged from low to high remaining capacity, starting with the energy storage battery packs with low remaining capacity and charging them to the set capacity threshold in one go. Then, the energy storage battery packs with low remaining capacity are selected for charging in turn. When the photovoltaic power generation is greater than the energy storage capacity of all energy storage battery packs, that is, when all energy storage battery packs are charged to the set capacity threshold, the excess power is fed into the grid for use. During the discharging process, the remaining capacity of each energy storage battery pack is obtained, a batch of energy storage battery packs with remaining capacity within a selected range are selected, and the number of charge and discharge cycles of the energy storage battery packs is retrieved. The discharge is then selected from low to high charge and discharge cycles. When the number of charge and discharge cycles is the same, the energy storage battery packs with more remaining capacity are discharged first. By using the above charging and discharging methods, the charging and discharging of all energy storage battery packs can be made relatively balanced, thereby appropriately extending the service life of all energy storage battery packs.

[0060] In this invention, the inspection mode of the inspection drone for the energy storage array is as follows: Each energy storage cabinet is equipped with a temperature sensor and a smoke sensor. When the temperature sensor detects that the temperature of the energy storage battery pack in the cabinet exceeds the set temperature value and cannot be reduced to the set temperature range even after prolonged liquid cooling (more than 10 minutes), the energy storage management module cuts off the energy storage battery pack from participating in the charging and discharging sequence. The coordinates and real-time temperature of the energy storage cabinet are transmitted to the control terminal, allowing maintenance personnel to be dispatched to the site for inspection and repair. After the temperature is restored to the set range, the energy storage management module puts the battery pack back into the charging and discharging sequence. When the smoke sensor detects that the smoke generated inside the energy storage cabinet reaches the set value, the energy storage management module immediately cuts off the charging and discharging of the energy storage cabinet and simultaneously sends the coordinates of the energy storage cabinet to the control terminal and the inspection drone. The inspection drone then plans a path to fly towards the energy storage cabinet to inspect it, obtain the on-site situation of the energy storage cabinet, and feeds it back to the control terminal.

[0061] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
