[0047] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0048] The following describes the monitoring method, device, electronic device and storage medium of the photovoltaic power generation system according to the embodiments of the present disclosure with reference to the accompanying drawings.

[0049] Figure 1 A schematic flow chart of a photovoltaic power generation system monitoring method provided in an embodiment of the present disclosure.

[0050] like Figure 1 As shown, the method comprises the following steps:

[0051] Step 101, collecting data to be monitored based on a preset device; wherein the data to be monitored includes data information of at least two monitoring data items.

[0052] In photovoltaic power generation systems, various sensors and monitoring devices are needed to collect key performance parameters in real time. These parameters include but are not limited to the temperature, light intensity, output voltage and current of photovoltaic panels. These data can be automatically collected through preset devices installed in the system, such as temperature sensors, light meters, voltage and current transformers. These data collection devices are usually connected to a central monitoring system, which is responsible for summarizing and recording all monitored data.

[0053] In order to ensure the integrity and accuracy of the data, the preset device should have high reliability and accuracy. In addition, the frequency of data collection also needs to be adjusted according to actual needs so that potential problems can be discovered in time and corresponding measures can be taken. For example, under extreme weather conditions, it may be necessary to increase the frequency of data collection to more closely monitor the status of the photovoltaic system. Specifically, the collection frequency and collection accuracy can be set according to actual needs, and the embodiments of the present application are not limited to this.

[0054] Step 102: call a monitoring threshold corresponding to the data item to be monitored in a preset database, and verify the data information of the data item to be monitored.

[0055] After the monitoring data is collected, it is compared with the preset monitoring thresholds. These thresholds are set during the system design phase based on historical data, manufacturer specifications, and industry standards. They represent the normal range of each monitoring indicator.

[0056] In the preset database, corresponding thresholds are stored for each monitoring data item. When new monitoring data is collected and entered into the system, a verification process is automatically triggered. This process involves comparing and analyzing the real-time data with the thresholds in the database to determine whether any indicators are beyond the normal range. If the monitored data exceeds the preset threshold range, it is considered a potential problem and requires further inspection and processing.

[0057] Step 103, when the verification result is that the data to be monitored is greater than or equal to the monitoring threshold, a fault alarm signal is generated and broadcast based on a preset broadcasting method.

[0058] When the monitoring data exceeds or equals the preset threshold, the system will automatically trigger the fault alarm process. This process first includes generating a clear fault alarm signal, which is usually sent to the operation interface of the monitoring system to alert the operator visually or audibly.

[0059] In addition to being displayed on the local monitoring system, fault alarm signals can also be disseminated through a variety of preset broadcasting methods. For example, alarm information can be sent to maintenance teams or individuals via SMS, email, or mobile app push, ensuring that they can be notified in a timely manner even when no one is on duty.

[0060] In addition, in order to improve response speed and efficiency, it can also be equipped with remote diagnosis function, which means that technicians can remotely access the system through the network, view real-time data and alarm information, and even directly perform remote troubleshooting in some cases.

[0061] The monitoring method of the photovoltaic power generation system provided by the present disclosure includes the following main technical solutions: collecting the data to be monitored based on a preset device; wherein the data to be monitored includes data information of at least two monitoring data items; calling the monitoring threshold corresponding to the data item to be monitored in the preset database, and verifying the data information of the data item to be monitored; when the verification result is that the data to be monitored is greater than or equal to the monitoring threshold, generating a fault alarm signal and broadcasting it based on a preset broadcasting method. Compared with the related art, the embodiment of the present application automatically collects the data to be monitored through a preset device, and calls the threshold corresponding to the monitoring data item in the database for verification. When the monitoring data exceeds or equals the threshold, the system immediately generates a fault alarm signal and broadcasts it in a preset manner, thereby realizing real-time and accurate fault warning. This automated monitoring and alarm mechanism greatly improves the efficiency of fault detection, reduces the need for manual intervention, and ensures the stable operation and safety of the system.

[0062] In some embodiments, the monitoring threshold includes a first monitoring threshold and a second monitoring threshold; the first monitoring threshold is less than the second monitoring threshold; when the monitored data exceeds different ranges, the processing methods to be adopted are also different. Figure 2 , Figure 2 A schematic flow chart of a photovoltaic power generation system monitoring method provided by an embodiment of the present disclosure includes:

[0063] Step 201: When the data to be monitored is greater than or equal to the first monitoring threshold and less than the second monitoring threshold, the fault alarm signal is generated and broadcast based on a preset broadcasting method.

[0064] When the monitored data exceeds the first monitoring threshold but has not yet reached the second monitoring threshold, this indicates that there may be a potential problem in the system, but it has not yet reached an emergency state. In this case, the system will generate a fault alarm signal and convey this information to the maintenance personnel or operator through a preset broadcast method (such as SMS, email or mobile application notification).

[0065] This level of alarm usually means that the system needs further inspection and evaluation to determine whether maintenance measures are required. The maintenance team can judge the severity of the problem based on the alarm information and decide whether to deal with it immediately or solve it later.

[0066] Step 202: When the data to be monitored is greater than or equal to the second monitoring threshold, the circuit breaker corresponding to the monitoring data is controlled to be disconnected, and the fault alarm signal is generated and broadcasted based on a preset broadcasting method.

[0067] When the monitoring data reaches or exceeds the second monitoring threshold, it indicates that there is a serious fault or abnormality in the system, which may cause damage to the equipment or affect the safe and stable operation of the entire system. In this case, in addition to generating a fault alarm signal and notifying relevant personnel through a preset broadcast method, the system will automatically control the corresponding circuit breaker to disconnect to prevent further losses or dangers, and can quickly isolate the faulty part to prevent the fault from spreading to other healthy parts. At the same time, this also provides the maintenance team with time to safely inspect and repair the fault without having to worry that the system will continue to run and may cause more serious problems.

[0068] In some embodiments, when the data to be monitored is collected based on the preset device in step 101, the following contents are also included:

[0069] Obtaining the current of each battery string in the battery pack and the numerical parameters of each inverter group; wherein the numerical parameters include at least one of AC and DC voltage, input, output current, active power, reactive power, electricity quantity, inverter frequency, and power factor;

[0070] Obtain the operating status of the electrical equipment and the grid values ​​on the grid side; wherein the grid values ​​include at least one of the grid voltage, grid frequency, and inverter operating condition.

[0071] In some embodiments, the detection data items may include the following: the current of each battery string group; the AC and DC voltage, input and output current, active power, reactive power, electricity consumption, inverter frequency, and power factor of each inverter group; the operating status of electrical equipment such as the inverter's fuses, AC and DC circuit breakers, low-voltage side circuit breakers, and high-voltage side switches of the box transformer, and the grid voltage is too high, too low, and the grid frequency is too high, too low; fault alarm signals such as DC voltage is too high, too low, inverter overload, inverter overheating, inverter short circuit, radiator overheating, inverter islanding, communication failure, and container transformer smoke detection signals.

[0072] By monitoring these parameters, we can understand whether the electrical equipment is working properly and whether there are any abnormalities on the power grid side, so that timely measures can be taken to adjust and optimize.

[0073] Optionally, when the verification result is that the data to be monitored is greater than or equal to the monitoring threshold, after a fault alarm signal is generated and broadcasted based on a preset broadcasting method, the method further includes:

[0074] Obtain control instructions input by the user, and perform operation control on the electrical equipment according to the control instructions; wherein the control instructions are obtained by remote operation or local unit operation.

[0075] The control function is divided into centralized control and decentralized control. Centralized control: The operator can remotely operate the inverter, box transformer low-voltage side circuit breaker and other electrical equipment through the keyboard or mouse. The system will provide the necessary operation steps and sufficient software and hardware verification functions to ensure the legality, safety, correctness and rationality of the operation. Decentralized control: Each circuit breaker can be manually controlled one-to-one in the local unit, and a remote / local selection switch can be set.

[0076] Optionally, after collecting the data to be monitored based on the preset device, the method further includes:

[0077] The data to be monitored is sent to a preset database based on a preset optical fiber ring network controller.

[0078] Each photovoltaic array area is equipped with a communication cabinet, which contains a photovoltaic sub-array controller, a data collector and a ring network switch. The string inverter in each array uses PLC carrier to communicate with the photovoltaic sub-array controller and then connects to the data collector via RS485. The tracking bracket control box, the box transformer measurement and control device in the sub-array communicate with the data collector via RS485, and finally connect to the preset database through the optical fiber ring network switch; in some embodiments, the preset database can be the photovoltaic monitoring background of the booster station, or it can be a higher-level control center. The specific embodiments of this application do not limit the preset database.
