It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

The server 104 obtains the photovoltaic grid-connected scheme file to be reviewed; the photovoltaic grid-connected scheme file to be reviewed records the system configuration of the photovoltaic power generation system to be connected; the photovoltaic power generation system to be connected is a photovoltaic power generation system to be connected to the power grid; the server 104 parses the photovoltaic grid-connected scheme file to be reviewed and determines at least one data to be reviewed; the server 104 obtains the review reference data corresponding to each data to be reviewed, and determines the review result of the photovoltaic grid-connected scheme file to be reviewed according to the review reference data and each data to be reviewed. Among them, the terminal 102 can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices, and the Internet of Things devices can be smart TVs, smart car-mounted devices, projection devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The head mounted device may be a virtual reality (VR) device, an augmented reality (AR) device, smart glasses, etc. The server 104 may be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services.

[0042] In an exemplary embodiment, Figure 2 As shown, a distributed photovoltaic grid-connected scheme review method is provided, and the method is applied to a server as an example for explanation, including the following steps S202 to S206. Among them:

[0043] Step S202, obtaining a photovoltaic grid-connected scheme file to be reviewed; the photovoltaic grid-connected scheme file to be reviewed records the system configuration of the photovoltaic power generation system to be connected; the photovoltaic power generation system to be connected is a photovoltaic power generation system to be connected to the power grid.

[0044] The photovoltaic grid-connected plan document to be reviewed may refer to information representing the system configuration of the photovoltaic power generation system to be connected. In actual applications, the photovoltaic power generation system to be connected may include a photovoltaic power generation system to be connected to the power grid.

[0045] As an example, during the photovoltaic grid-connected process, when a photovoltaic power generation system needs to be connected to the power grid, the photovoltaic power generation system can be used as the photovoltaic power generation system to be connected, and the server needs to review the photovoltaic power generation system to be connected to ensure that after the power grid is connected to the photovoltaic power generation system to be connected, the power grid and the photovoltaic power generation system to be connected can operate normally and power can be transmitted normally between the power grid and the photovoltaic power generation system to be connected. When reviewing the photovoltaic power generation system to be connected, the server can first obtain the photovoltaic grid-connected plan file to be reviewed. The photovoltaic grid-connected plan file to be reviewed can be used to describe / record the system configuration of the photovoltaic power generation system to be connected (such as photovoltaic capacity, current, power factor, etc.). The server can analyze the relevant data in the photovoltaic grid-connected plan file to be reviewed to determine whether the photovoltaic grid-connected plan file to be reviewed is feasible (or whether it has passed the review).

[0046] Step S204, parsing the photovoltaic grid-connected solution file to be reviewed, and determining at least one data to be reviewed.

[0047] The data to be reviewed may refer to the data that needs to be analyzed in the photovoltaic grid-connected plan file to be reviewed. In practical applications, the data to be reviewed may be used to characterize the key verification information (such as photovoltaic capacity, current, power factor, etc.) of the photovoltaic power generation system to be connected.

[0048] As an example, the server can parse the photovoltaic grid-connected scheme file to be reviewed, determine the various data in the photovoltaic grid-connected scheme file to be reviewed, and filter out the data that needs to be reviewed from the various data as the data to be reviewed. In actual applications, the types of photovoltaic power generation systems are different, and the data that needs to be reviewed may be different. The server can accurately filter out the corresponding data from the photovoltaic grid-connected scheme file to be reviewed as the data to be reviewed according to the type of photovoltaic power generation system represented by the photovoltaic grid-connected scheme file to be reviewed.

[0049] Step S206, obtaining the review reference data corresponding to each data to be reviewed, and determining the review result of the photovoltaic grid-connected solution file to be reviewed according to the review reference data and each data to be reviewed.

[0050] Among them, the review reference data may refer to information used to determine whether the data to be reviewed meets the corresponding data requirements. In practical applications, the data to be reviewed and the review reference data may correspond one to one. The review reference data may be pre-set or calculated based on the data in the photovoltaic grid-connected scheme file to be reviewed.

[0051] As an example, after obtaining the data to be reviewed, the server can obtain the review reference data corresponding to each data to be reviewed from a preset database, and / or calculate the review reference data corresponding to each data to be reviewed based on the data in the photovoltaic grid-connected scheme file to be reviewed. Then the server can compare the review reference data with each data to be reviewed, and determine the review result of the photovoltaic grid-connected scheme file to be reviewed based on the comparison result of each data to be reviewed. In actual application, when each data to be reviewed meets the corresponding data requirements, the server can determine that the review result of the photovoltaic grid-connected scheme file to be reviewed is passed. The review result of passed can indicate that the photovoltaic power generation system to be connected corresponding to the photovoltaic grid-connected scheme file to be reviewed can be connected to the power grid after the construction is completed in accordance with the photovoltaic grid-connected scheme file to be reviewed; as long as there is data that does not meet the corresponding data requirements in each data to be reviewed, the server can determine that the review result of the photovoltaic grid-connected scheme file to be reviewed is failed to pass the review. At this time, the system configuration of the photovoltaic power generation system to be connected needs to be modified and adjusted. After the modification and adjustment are completed, a new photovoltaic grid-connected scheme file to be reviewed can be obtained. If the new photovoltaic grid-connected scheme file to be reviewed is still not passed, the system configuration of the photovoltaic power generation system needs to be modified again until the photovoltaic grid-connected scheme file to be reviewed is passed. In a specific implementation, when the review result of the photovoltaic grid-connected plan file to be reviewed is failure to pass the review, the review result of the photovoltaic grid-connected plan file to be reviewed may include data that does not meet the corresponding data requirements and alarm information corresponding to the data, so as to carry out targeted modification and adjustment of the system configuration of the photovoltaic power generation system.

[0052] In the above-mentioned distributed photovoltaic grid-connected scheme review method, by obtaining the photovoltaic grid-connected scheme file to be reviewed, the system configuration of the photovoltaic power generation system to be connected recorded in the photovoltaic grid-connected scheme file to be reviewed is determined; the photovoltaic power generation system to be connected is a photovoltaic power generation system to be connected to the power grid; the photovoltaic grid-connected scheme file to be reviewed is parsed to determine at least one data to be reviewed, so as to accurately obtain the data to be reviewed related to the photovoltaic grid-connected review based on the photovoltaic grid-connected scheme file to be reviewed; the review reference data corresponding to each data to be reviewed is obtained, and the review result of the photovoltaic grid-connected scheme file to be reviewed is determined according to the review reference data and each data to be reviewed, so as to conduct a detailed review of each data to be reviewed based on the review reference data, analyze the safety of the photovoltaic grid-connected scheme, and be able to conduct a detailed analysis of the data to be reviewed in the photovoltaic grid-connected scheme file to be reviewed based on the review reference data, and accurately and automatically check and review the photovoltaic grid-connected scheme in combination with the analysis results, generate corresponding review results, and thus improve the efficiency of generating review results.

[0053] In an exemplary embodiment, a photovoltaic grid-connected scheme file to be reviewed is parsed to determine at least one data to be reviewed, including: parsing the photovoltaic grid-connected scheme file to be reviewed to determine voltage level information corresponding to the photovoltaic grid-connected scheme file to be reviewed; filtering out the data to be reviewed from the photovoltaic grid-connected scheme file to be reviewed according to the voltage level information and a preset mapping rule; the mapping rule characterizes the mapping relationship between the voltage level information and the data to be reviewed.

[0054] The voltage level information may refer to information characterizing the voltage / voltage range of the power distribution network to which the photovoltaic power generation system to be connected needs to be connected.

[0055] Among them, the preset mapping rules may refer to pre-set information used to characterize the mapping relationship between voltage level information and the data to be reviewed. In actual applications, the voltage level information is different, the voltage / voltage range of the distribution network may be different, and therefore the data to be analyzed (i.e., the data to be reviewed) may also be different.

[0056] As an example, the server can parse the photovoltaic grid-connected plan file to be reviewed and determine the voltage level information corresponding to the photovoltaic grid-connected plan file to be reviewed. Since the voltage level information is different, the voltage / voltage range of the distribution network that the photovoltaic power generation system needs to be connected to will be different, and the data to be reviewed that need to be analyzed will also be different. At this time, the server can find the data to be reviewed from the song data in the photovoltaic grid-connected plan file to be reviewed based on the voltage level information and the preset mapping rules.

[0057] In this embodiment, by parsing the photovoltaic grid-connected scheme file to be reviewed, the voltage level information corresponding to the photovoltaic grid-connected scheme file to be reviewed is determined; according to the voltage level information and the preset mapping rules, the data to be reviewed is screened out from the photovoltaic grid-connected scheme file to be reviewed; the mapping rules characterize the mapping relationship between the voltage level information and the data to be reviewed, and can be combined with the preset mapping rules, based on the voltage level information corresponding to the photovoltaic grid-connected scheme file to be reviewed, to accurately screen out the data to be reviewed that needs to be analyzed from the photovoltaic grid-connected scheme file to be reviewed, thereby providing a data basis for subsequently determining the review results based on the data to be reviewed.

[0058] In some embodiments, data to be reviewed are screened out from the photovoltaic grid-connected scheme file to be reviewed according to voltage level information and preset mapping rules, including: when the voltage level information corresponding to the photovoltaic grid-connected scheme file to be reviewed is a first voltage level, determining a first data category according to the first voltage level and the preset mapping rules; the first data category includes photovoltaic capacity, photovoltaic short-circuit current, short-circuit ratio, power factor, maximum voltage deviation, current carrying capacity and system protection configuration information; and using the data corresponding to the first data category in the photovoltaic grid-connected scheme file to be reviewed as the data to be reviewed.

[0059] Among them, the first voltage level may refer to information indicating that the voltage / voltage range of the distribution network to which the photovoltaic power generation system to be connected needs to be connected is the first voltage. In practical applications, the voltage of the first voltage level may be reported as but not limited to 10KV.

[0060] Among them, the first data category may refer to information that represents the represented meaning of the data. In actual applications, the represented meaning of the data may include but is not limited to photovoltaic capacity, photovoltaic short-circuit current, short-circuit ratio, power factor, maximum voltage deviation, current carrying capacity and system protection configuration information, etc. The system protection configuration information may include relay protection type and switchgear protection configuration parameters. The represented meaning of the data can be used as a data type.

[0061] As an example, when the voltage level information corresponding to the photovoltaic grid-connected plan file to be reviewed is the first voltage level, the server can determine that the voltage / voltage range of the distribution network that the photovoltaic power generation system to be connected needs to be connected is the first voltage (such as 10KV), and then the server can determine the first data category based on the first voltage level and the preset mapping rule. The server can use the data corresponding to the first data category in the photovoltaic grid-connected plan file to be reviewed (such as photovoltaic capacity, photovoltaic short-circuit current, short-circuit ratio, power factor, maximum voltage deviation, current carrying capacity and system protection configuration information, etc.) as the data to be reviewed.

[0062] In this embodiment, when the voltage level information corresponding to the photovoltaic grid-connected scheme file to be reviewed is the first voltage level, the first data category is determined according to the first voltage level and the preset mapping rule; the first data category includes photovoltaic capacity, photovoltaic short-circuit current, short-circuit ratio, power factor, maximum voltage deviation, current carrying capacity and system protection configuration information; the data corresponding to the first data category in the photovoltaic grid-connected scheme file to be reviewed is used as the data to be reviewed, and the corresponding category data can be accurately screened out from the photovoltaic grid-connected scheme file to be reviewed based on the first voltage level information in combination with the preset mapping rules as the data to be reviewed, thereby providing a data basis for the subsequent determination of the review results based on the data to be reviewed.

[0063] In some embodiments, the review reference data includes a preset safe current carrying capacity, and the review results of the photovoltaic grid-connected scheme file to be reviewed are determined based on the review reference data and the data to be reviewed, including: determining the photovoltaic capacity of the grid-connected feeder based on the photovoltaic capacity of the photovoltaic power generation system to be connected, the photovoltaic capacity of the photovoltaic power generation system already connected to the grid, and the photovoltaic capacity of the photovoltaic power generation system under construction; determining the rated capacity of the feeder based on the preset safe current carrying capacity; determining the review results of the photovoltaic grid-connected scheme file to be reviewed based on the difference between the photovoltaic capacity of the grid-connected feeder and the rated capacity of the feeder.

[0064] The grid-connected feeder photovoltaic capacity may refer to information representing the sum of the photovoltaic capacity of the photovoltaic power generation system to be connected, the photovoltaic capacity of the photovoltaic power generation system already connected to the grid, and the photovoltaic capacity of the photovoltaic power generation system under construction.

[0065] Among them, the safe current carrying capacity may refer to the maximum current that a cable or wire can continuously pass for a long time under given environmental conditions without exceeding the maximum allowable operating temperature of the cable or wire.

[0066] The feeder rated capacity refers to the maximum electric power that the feeder can transmit safely and stably under normal working conditions.

[0067] As an example, the server can sum the photovoltaic capacity of the photovoltaic power generation system to be connected, the photovoltaic capacity of the photovoltaic power generation system that has been connected to the power grid, and the photovoltaic capacity of the photovoltaic power generation system under construction, and use the sum as the photovoltaic capacity of the grid-connected feeder. Then the server can determine the rated capacity of the feeder based on the preset safe current carrying capacity in the review reference data. After that, the server can compare the photovoltaic capacity of the grid-connected feeder with the rated capacity of the feeder to determine the difference between the photovoltaic capacity of the grid-connected feeder and the rated capacity of the feeder. When the photovoltaic capacity of the grid-connected feeder is less than or equal to the rated capacity of the feeder, it is determined that the photovoltaic capacity of the photovoltaic power generation system to be connected has passed the review. At this time, the review result of the photovoltaic capacity of the photovoltaic power generation system to be connected can be expressed as the photovoltaic capacity review passed. Similarly, the server can also determine the corresponding review result based on other data to be reviewed (such as photovoltaic short-circuit current, short-circuit ratio, power factor, maximum voltage deviation, current carrying capacity, system protection configuration information) and the corresponding review reference data. The server can determine the review result of the photovoltaic grid-connected scheme file to be reviewed based on the review results of each data to be reviewed.

[0068] In this embodiment, the photovoltaic capacity of the grid-connected feeder is determined according to the photovoltaic capacity of the photovoltaic power generation system to be connected, the photovoltaic capacity of the photovoltaic power generation system already connected to the power grid, and the photovoltaic capacity of the photovoltaic power generation system under construction; the rated capacity of the feeder is determined according to the preset safe current carrying capacity; and the review result of the photovoltaic grid-connected scheme file to be reviewed is determined according to the difference between the photovoltaic capacity of the grid-connected feeder and the rated capacity of the feeder. The data to be reviewed in the photovoltaic grid-connected scheme file to be reviewed can be analyzed from the perspective of photovoltaic capacity, thereby accurately obtaining the review result of the photovoltaic grid-connected scheme file to be reviewed, and improving the accuracy of the review result of the photovoltaic grid-connected scheme file to be reviewed.

[0069] In some embodiments, data to be reviewed are screened out from the photovoltaic grid-connected scheme file to be reviewed according to voltage level information and preset mapping rules, including: when the voltage level information corresponding to the photovoltaic grid-connected scheme file to be reviewed is the second voltage level, determining the second data category according to the second voltage level and the preset mapping rules; the second data category includes transformer capacity, photovoltaic short-circuit current, short-circuit ratio, power factor, maximum voltage deviation and system protection configuration information; the voltage of the first voltage level is higher than the voltage of the second voltage level; and the data corresponding to the second data category in the photovoltaic grid-connected scheme file to be reviewed is used as the data to be reviewed.

[0070] Among them, the second voltage level may refer to information indicating that the voltage / voltage range of the distribution network to which the photovoltaic power generation system to be connected needs to be connected is the second voltage. In actual applications, the voltage of the second voltage level may be reported as but not limited to 380V.

[0071] Among them, the second data category may refer to information that represents the represented meaning of the data. In actual applications, the represented meaning of the data may include but is not limited to transformer capacity, photovoltaic short-circuit current, short-circuit ratio, power factor, maximum voltage deviation and system protection configuration information, etc. The system protection configuration information may include inverter protection function configuration parameters and grid connection point relay protection configuration parameters. The represented meaning of the data can be used as a data type.

[0072] As an example, when the voltage level information corresponding to the photovoltaic grid-connected plan file to be reviewed is the second voltage level, the server can determine that the voltage / voltage range of the distribution network to which the photovoltaic power generation system to be connected needs to be connected is the second voltage (such as 380V), and then the server can determine the second data category based on the second voltage level and the preset mapping rules. The server can use the data corresponding to the second data category in the photovoltaic grid-connected plan file to be reviewed (such as transformer capacity, photovoltaic short-circuit current, short-circuit ratio, power factor, maximum voltage deviation and system protection configuration information, etc.) as the data to be reviewed.

[0073] In this embodiment, when the voltage level information corresponding to the photovoltaic grid-connected scheme file to be reviewed is the second voltage level, the second data category is determined according to the second voltage level and the preset mapping rule; the second data category includes transformer capacity, photovoltaic short-circuit current, short-circuit ratio, power factor, maximum voltage deviation and system protection configuration information; the voltage of the first voltage level is higher than the voltage of the second voltage level; the data corresponding to the second data category in the photovoltaic grid-connected scheme file to be reviewed is used as the data to be reviewed, and it can be combined with the preset mapping rules and based on the second voltage level information, the corresponding category data can be accurately screened out from the photovoltaic grid-connected scheme file to be reviewed as the data to be reviewed, thereby providing a data basis for the subsequent determination of the review results based on the data to be reviewed.

[0074] In some embodiments, the review reference data includes the total installed capacity, and the review result of the photovoltaic grid-connected scheme file to be reviewed is determined based on the review reference data and the data to be reviewed, including: obtaining the transformer capacity of each transformer corresponding to the photovoltaic grid-connected scheme file to be reviewed; comparing the transformer capacity of each transformer with the total installed capacity one by one, and determining the review result of the photovoltaic grid-connected scheme file to be reviewed based on the comparison result.

[0075] The total installed capacity may refer to the total installed capacity of the photovoltaic power generation system to be connected.

[0076] As an example, the server can obtain the transformer capacity of each transformer corresponding to the photovoltaic grid-connected scheme file to be reviewed, and then compare the transformer capacity of each transformer with the total installed capacity in the review reference data one by one, and determine the review result of the photovoltaic grid-connected scheme file to be reviewed based on the comparison result. Specifically, if the transformer capacity of each transformer is greater than or equal to the total installed capacity in the review reference data, the server can determine that the photovoltaic power generation system to be connected has passed the transformer capacity review. At this time, the transformer capacity review result of the photovoltaic power generation system to be connected can be expressed as the transformer capacity review passed. Similarly, the server can also determine the corresponding review result based on other data to be reviewed (such as photovoltaic short-circuit current, short-circuit ratio, power factor, maximum voltage deviation and system protection configuration information) and the corresponding review reference data. The server can determine the review result of the photovoltaic grid-connected scheme file to be reviewed based on the review results of each data to be reviewed.

[0077] In this embodiment, by obtaining the transformer capacity of each transformer corresponding to the photovoltaic grid-connected scheme file to be reviewed; comparing the transformer capacity of each transformer with the total installed capacity one by one, and determining the review result of the photovoltaic grid-connected scheme file to be reviewed according to the comparison result, the data to be reviewed in the photovoltaic grid-connected scheme file to be reviewed can be analyzed from the perspective of transformer capacity, thereby accurately obtaining the review result of the photovoltaic grid-connected scheme file to be reviewed, and improving the accuracy of the review result of the photovoltaic grid-connected scheme file to be reviewed.

[0078] In some embodiments, the review results include review opinion information, and the above method also includes: determining the quantity information and review opinion information of the data to be reviewed that failed the review based on the review results; obtaining the review result generation time corresponding to the review results; sending the quantity information, review opinion information and review result generation time to the terminal; the terminal is used to display the quantity information, review opinion letter and review result generation time to the user.

[0079] The quantity information may refer to information representing the quantity of the to-be-examined data that has not passed the examination.

[0080] Among them, the examination opinion information may refer to the information of the examination opinion on the pending data that failed the examination. In practical applications, the examination opinion information may include a detailed description of the reasons why the pending data failed the examination. The pending data that failed the examination may be regarded as a kind of examination question.

[0081] The time taken to generate the review result may refer to information representing the time required to generate the review result.

[0082] As an example, the server can determine the amount of data to be reviewed that failed the review and obtain the review opinion information of the data to be reviewed that failed the review according to the review result, and then the server can send the review result generation time corresponding to the review result, the amount of data to be reviewed that failed the review, and the review opinion information to the terminal, such as Figure 3 As shown, a schematic diagram of a display interface is provided.
