[0043] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] The operation mode of the power system refers to the working state and operation strategy of the power system under different conditions, which ensures that the power system can operate safely, reliably and economically. Figure 1 , Figure 1 A schematic diagram of a related technology of an online splicing method for a power grid operation mode provided by an embodiment of the present application, such as Figure 1 As shown in the figure, the power grid company can be classified into annual, quarterly, monthly and daily operation modes according to the time scale. Each time the operation mode is done, the person in charge of each province needs to adjust the data in the form of text files and then hand it over to the general dispatching. Then the relevant personnel of the general dispatching will verify and manually merge the text data files. Because the whole process is manually processed based on text files, it is not only inefficient, but also prone to errors. There is no effective distinction between which data is not editable by the authority. All data is squeezed into a text file, which is not intuitive to browse. If the data is changed incorrectly, there is no effective verification prompt. In addition, the learning cost for novices is high, so a lot of manpower and time costs have to be invested.

[0045] The method provided by the present application has strict data authority control. In addition to the management user, only the group users corresponding to the current mode can view and edit the mode data. The method provided by the present application can be implemented in the form of a work platform, with a friendly data editing and data verification interface, which reduces the editing difficulty and submission operation efficiency of the user and improves the fault tolerance rate. The background application is fully automatic, and data splicing and merging can be completed without manual intervention in the middle. It is not only efficient, but also free of other problems caused by manual misoperation. In the process of mode splicing, the mode splicing conditions are set through the work platform, so that the automation of mode splicing and the verification of the validity of mode splicing can be realized. By setting the line distribution, flow characteristics, stability and safety conditions between the main mode and each subordinate mode, the validity of the mode splicing process and the data applied for mode splicing are ensured, thereby ensuring the validity of the target operation mode.

[0046] Specifically, implementing the method corresponding to this application can achieve at least the following technical effects:

[0047] The data is presented intuitively in a table format;

[0048] Provides a rich data display interface, where data is displayed by type, and different device types have their own list display pages;

[0049] Provides quick retrieval and sorting functions to facilitate users to observe and locate data quickly;

[0050] Convenient editing function not only improves user work efficiency but also avoids data errors caused by misoperation;

[0051] Provide effective data permissions so that each user can see the data within the corresponding permission range and the editable data, thus avoiding data leakage and misoperation problems;

[0052] Provide effective data verification and restrict data formats to prevent users from mistakenly filling in or randomly filling in data that is not allowed;

[0053] It has fully automatic and efficient data splicing, and the data splicing process can be completed without user intervention, which greatly reduces labor and time costs.

[0054] Among them, for the mode splicing process, this application sets corresponding mode splicing conditions to ensure the validity of the mode splicing part.

[0055] In summary, the technical concept of the present application is that the method provided by the present application is applied to a target configuration system including a general regulation point and multiple intermediate regulation points to realize data coordination between the general regulation point and each intermediate regulation point, the general regulation point determines the overall first operating mode and delegates it to each intermediate regulation point, each intermediate regulation point generates a second operating mode according to the first operating mode and reports it to the general regulation point, the general regulation point determines the main mode and the subordinate mode in the second operating mode, and restricts the splicing process of each operating mode through one or more of topological conditions, flow conditions or risk coefficient conditions, and realizes online splicing based on the splicing conditions. Therefore, since a process of determining and verifying whether each second operating mode meets the mode splicing conditions is added in the process of determining the target operating mode, the validity of the mode splicing process and the data applied for mode splicing is ensured, thereby ensuring the validity of the target operating mode, and the interaction process of the operating mode data is carried out online, realizing online data interaction and data sharing of the entire mode configuration process, and improving the coordination and real-time performance between nodes in the process of configuring the power grid operation mode.

[0056] See also Figure 2 , Figure 2 A flow chart of an online splicing method for power grid operation mode provided by an embodiment of the present application is as follows: Figure 2 As shown, the method is applied to a target configuration system, the target configuration system includes a total adjustment point and multiple intermediate adjustment points, and the method includes:

[0057] S101, determining a first operating mode through the master regulating point, and sending the determined first operating mode to each of the intermediate regulating points;

[0058] S102, processing the first operation mode through each of the intermediate adjustment points to generate a second operation mode, and reporting the determined second operation mode to the overall adjustment point;

[0059] S103, determining a main mode and at least one subordinate mode in each of the second operating modes through the total adjustment point, and performing mode splicing on the main mode and each of the subordinate modes according to a splicing condition to determine a target operating mode;

[0060] Wherein, the splicing condition includes one or more of a topological condition, a flow condition or a risk coefficient condition;

[0061] Among them, the topological condition is used to indicate the line distribution between the main mode and each of the slave modes, the flow condition is used to indicate the flow characteristics of the main mode and each of the slave modes, and the risk coefficient condition is used to indicate the stability and safety of the main mode and each of the slave modes.

[0062] The method provided in the present application is applied to a target configuration system including a general regulation point and multiple intermediate regulation points to achieve data coordination between the general regulation point and each intermediate regulation point. The general regulation point determines the overall first operating mode and delegates it to each intermediate regulation point. Each intermediate regulation point generates a second operating mode according to the first operating mode and reports it to the general regulation point. The general regulation point determines the master mode and the slave mode in the second operating mode, and restricts the splicing process of each operating mode through one or more of topological conditions, flow conditions or risk coefficient conditions, and realizes online splicing based on the splicing conditions. Therefore, since a process of determining and verifying whether each second operating mode meets the mode splicing conditions is added in the process of determining the target operating mode, the validity of the mode splicing process and the data applied for mode splicing is ensured, thereby ensuring the validity of the target operating mode, and the interaction process of the operating mode data is carried out online, realizing online data interaction and data sharing in the whole process of mode configuration, and improving the coordination and real-time performance between nodes in the process of configuring the power grid operation mode.

[0063] As a feasible implementation method, the topological conditions include:

[0064] Determine whether the lines of each of the subordinate modes have an intersection with the main mode, and if there is an intersection, take the line corresponding to the main mode as the first target line;

[0065] It is determined whether there is an intersection between the lines of each subordinate mode. If there is an intersection, the lines are overwritten according to the order in which the data of each subordinate mode is stored in the database, and the line corresponding to the newly stored subordinate mode is used as the second target line.

[0066] Specifically, the splicing methods based on topological structure analysis in practical applications can include:

[0067] Identification and processing of line intersections: When the master control point receives the second operation mode reported by each intermediate control point, it first analyzes the line intersections of the slave mode and the master mode. For each line, it can be regarded as a topological structure consisting of multiple nodes and branches connecting these nodes. Using graph theory algorithms, such as depth-first search (DFS) or breadth-first search (BFS), traverse the line topology of each slave mode and the master mode.

[0068] For example, if a line of a slave mode has common nodes and branches with a line of the master mode in topology, it is determined that there is an intersection. In this case, the line corresponding to the master mode is used as the first target line. This means that when splicing, the topological integrity of the line of the master mode is retained, and the line parameters of the intersection of the slave mode and the master mode are adjusted to be consistent with the master mode.

[0069] Intersection processing between subordinate modes: When processing the intersection of lines between subordinate modes, overwrite them according to the order in which the data of each subordinate mode is stored. Record the storage timestamp of the line data of each subordinate mode in the system. When it is found that there is a line intersection between subordinate modes, compare their storage times.

[0070] Specifically, suppose there are two subordinate modes A and B, and the storage time of A is earlier than that of B. If their routes intersect, in the splicing process, the route corresponding to B (the newly stored subordinate mode) is used as the second target route. This can be achieved by modifying the route parameters of the intersection part of A with B to make it consistent with B.

[0071] Since the splicing conditions include one or more of topological conditions, flow conditions or risk coefficient conditions, wherein the topological conditions are used to indicate the line distribution between the main mode and each of the subordinate modes, the flow conditions are used to indicate the flow characteristics of the main mode and each of the subordinate modes, and the risk coefficient conditions are used to indicate the stability and safety of the main mode and each of the subordinate modes, the specific application scenarios may also include a splicing method based on flow calculation or a splicing method based on risk assessment, etc.

[0072] For the splicing method based on power flow calculation, the specific application scenarios may include:

[0073] Flow calculation initialization: After determining the master mode and slave mode, for each operation mode (including master mode and slave mode), the flow calculation model is constructed based on its line parameters (such as resistance, reactance, admittance, etc.) and node injection power (generated power, load power, etc.). The flow calculation method such as Newton-Raphson method or fast decomposition method is used to initialize the flow calculation for each operation mode.

[0074] Consider the flow adjustment of intersection: When there is a line intersection between the slave mode and the master mode, the flow calculation result of the master mode is used as the benchmark during the flow calculation process. Analyze the flow distribution on the intersection line, such as power flow direction, voltage amplitude, etc. According to the flow state of the master mode, adjust the relevant parameters of the intersection line in the slave mode to ensure that the flow characteristics of the intersection line are consistent with the master mode after splicing.

[0075] When there is a line intersection between subordinate modes, the power flow calculation results of the subordinate mode that enters the warehouse later will overwrite the power flow parameters of the subordinate mode that enters the warehouse earlier on the intersection line according to the order of entry. For example, if the voltage amplitude and phase angle calculated by the subordinate mode that enters the warehouse later on the intersection line are different from those of the subordinate mode that enters the warehouse earlier, the corresponding parameters of the subordinate mode that enters the warehouse earlier will be adjusted to the values ​​of the subordinate mode that enters the warehouse later to achieve mode splicing.

[0076] For the splicing method based on risk assessment, specific application scenarios may include:

[0077] Determination of risk assessment indicators: In order to comprehensively consider the safety of system operation during the splicing process, a risk assessment indicator system is established for each operation mode (master mode and slave mode). The indicators may include line overload risk, voltage over-limit risk, transient stability risk, etc. The weight and evaluation criteria of each indicator are determined through historical data, simulation calculation and other methods.

[0078] Risk-based splicing decision: When judging the intersection of the lines of the slave mode and the master mode, not only the topology structure is considered, but also the risk assessment results are combined. If there is a high risk in the intersection of the lines of a slave mode and the master mode (such as the line overload risk exceeds the set threshold), the intersection is optimized and adjusted on the basis of taking the master mode as the first target line. For example, the power generation plan or load distribution of the master mode or slave mode on the intersection line can be adjusted to reduce the risk.

[0079] For the intersection of the lines between the subordinate modes, they are covered according to the order of entry and the risk assessment results. If the risk assessment result of the newly entered subordinate mode on the intersection line is better than that of the old subordinate mode, the line corresponding to the newly entered subordinate mode is used as the second target line, and the parameters of other subordinate modes are adjusted accordingly to ensure that the target operation mode after splicing has a lower operation risk.

[0080] This implementation is based on the line distribution between the main mode and each slave mode, and determines whether there is a line intersection between the modes according to the preset topological conditions, and performs corresponding data coverage or data selection when there is a line intersection. Specifically, when there is an intersection, it is covered according to the principles of main mode priority and latest data priority, avoiding splicing failure caused by data duplication in the splicing process, thereby improving the effectiveness and efficiency of the target operation mode splicing process.

[0081] The present application realizes data interaction through a working platform, and an identity authentication mechanism may be introduced in the data interaction process between the general coordination and the intermediate coordination to ensure the validity and security of the data. Furthermore, in other implementations, the data of each operating mode may be verified to ensure the validity of the splicing process of the final target operating mode, and when it is found that the data does not meet the preset conditions, timely retroactive modification may be performed to improve the validity of the data and the efficiency of method compilation.

[0082] As an optional implementation manner, the overall adjustment point performs mode splicing on the second operating modes of each of the intermediate adjustment points, and before determining the target operating mode, the method further includes:

[0083] Determine the splicing conditions;

[0084] If it is determined that each of the second operating modes meets the splicing condition, the second operating modes of each of the intermediate adjustment points are spliced ​​to determine a target operating mode.

[0085] In this embodiment, before the general adjustment point splices the second operating modes uploaded by each intermediate adjustment point, the mode splicing conditions are first determined to verify whether each second operating mode meets the corresponding splicing conditions. Only when the second operating mode data is complete and the data format, equipment and line conditions meet the preset requirements can the mode splicing be performed to determine the target operating mode, thereby improving the effectiveness of the target operating mode splicing process.

[0086] As an optional implementation, the splicing conditions include one or more of the following combinations:

[0087] The number of the second operating modes is within a preset range;

[0088] The data in each of the second operation modes conforms to a preset format;

[0089] Each of the second operating modes meets the preset verification conditions.

[0090] This embodiment determines the stitching conditions of the second operating mode, determines whether the number and data format of the second operating mode meet the preset requirements, and determines whether the substantive content of each of the second operating modes is valid through preset verification conditions, thereby ensuring the validity of the second operating mode and improving the validity of the target operating mode stitching process.

[0091] As an optional implementation manner, the determination process of the verification condition includes:

[0092] It is determined whether the target areas corresponding to the second operating modes have any intersection. If the target areas corresponding to the second operating modes do not have any intersection, the verification condition is met.

[0093] In actual applications, this embodiment determines whether the target areas corresponding to the second operating modes uploaded by each central adjustment have an intersection. If there is no intersection, it means that the data is valid and meets the verification conditions. Therefore, the validity of the data is restricted from the target area corresponding to the second operating mode, thereby improving the effectiveness of the target operating mode splicing process.

[0094] As an optional implementation manner, the verification condition determination process further includes:

[0095] A power flow calculation is performed for each of the second operating modes. If the power flow calculation results of each of the second operating modes converge, the verification condition is met.

[0096] In actual applications, this embodiment determines whether the power flow calculation results corresponding to the second operating mode uploaded by each central control are converged. If the power flow calculation results of each second operating mode are converged, it means that the data is valid and meets the verification conditions. Therefore, the validity of the data is restricted based on the essential content of the second operating mode, thereby improving the effectiveness of the target operating mode splicing process.

[0097] As an optional implementation manner, the verification condition determination process further includes:

[0098] It is determined whether the second operating mode data corresponding to each of the intermediate adjustment points have been submitted to the overall adjustment point. If the second operating mode data corresponding to each of the intermediate adjustment points have been submitted to the overall adjustment point, the verification condition is met.

[0099] In actual applications, this embodiment determines whether the second operating mode uploaded by each intermediate adjustment has been completely uploaded. If it is completely uploaded, it means that the data is valid and meets the verification conditions. Therefore, the validity of the data is restricted from the data integrity corresponding to the second operating mode, thereby improving the effectiveness of the target operating mode splicing process.

[0100] Specifically, the aforementioned verification methods can be implemented in specific application scenarios in the following ways:

[0101] In the operation mode splicing process, at least 2 or more operation modes are required for splicing, but no more than 10. If there are more than 10, some operation modes can be eliminated or nested splicing can be performed according to specific working conditions;

[0102] Splicing scenarios and processes: If the headquarters needs to make a set of mode data for the entire network, then the general dispatch needs to send the equipment data to the regional dispatch according to their respective areas, and then the regional dispatch will edit the mode data and submit it to the headquarters. At this time, the headquarters needs to splice the data submitted by each regional dispatch to form a new mode data, so it is necessary to ensure the second operating mode of each regional dispatch.

[0103] The selected operation mode sets do not allow the study areas to overlap;

[0104] Before splicing the modes, you need to check whether the selected operating mode can be calculated. If it can be calculated, splicing will be performed. Otherwise, relevant abnormal information will be prompted.

[0105] Verification rules: The study areas of all the selected methods that need to be spliced ​​cannot have intersections. If there are intersections, the verification fails, indicating that the data has an abnormal intersection of the study areas; otherwise, the verification passes. In specific application scenarios, the study area can be the city and province to which the plant station belongs, that is, the corresponding area of ​​the central survey described in this application.

[0106] Mode splicing is to merge data for each operation mode. The first mode is the main mode. The main reason is that the two ends of the AC or DC line are connected to two power plants, and these two plants may belong to different research areas. Therefore, the line is divided according to the research area, which forms the problem of boundary line data ownership. The boundary line problem mainly includes the phenomenon that the power plant to which one end belongs is in the research area of ​​the current mode, while the other end is not. If the boundary line of the non-main mode exists in the main mode, then the main mode shall prevail. Otherwise, the non-main mode shall be sorted in order, and the first-come-first-served order shall prevail. For other devices that do not have boundary problems, data can be merged according to the research area to which they belong.

[0107] See also Figure 3 , Figure 3 A flow chart of an online splicing method for power grid operation mode provided by an embodiment of the present application is as follows: Figure 3 As shown, when various embodiments are combined and applied, the method may include:

[0108] How to create the person in charge of the general dispatch;

[0109] The person in charge of the overall coordination adds team members to the current mode;

[0110] The person in charge or team members can edit the current mode data and can also send it to the person in charge of each province;

[0111] After receiving the issued method, the provincial leaders will assign members to this method:

[0112] When each province completes its own data, the person in charge will submit it to the general survey for consolidation;

[0113] When the general dispatch clicks merge, it verifies whether the methods sent to each province have been submitted. If they have been submitted, the background application will splice the method data. Otherwise, relevant abnormal information will be prompted.

[0114] Among them, provinces and central adjustment should be understood equivalently in this application. Central adjustment divides the target area into provinces, and person in charge, team leader and team member are used to indicate different user identities to illustrate the effect of limiting user permissions in the method provided in this application.

[0115] like Figure 4 As shown, Figure 4 A schematic diagram of the effect of the online splicing method of the power grid operation mode provided by an embodiment of the present application is used to illustrate the judgment conditions for judging whether the data in each of the aforementioned second operation modes meets the preset form:

[0116] The work platform corresponding to this application provides an intuitive data editing interface and complete data verification functions, so there is no need to worry about data confusion or missing caused by misoperation or improper operation.

[0117] The main data verification is as follows:

[0118] Data input is classified by data type. If the numeric type is not allowed to be filled with letters and special symbols, and if the integer type is not allowed to be entered with decimal points and other floating point types;

[0119] For floating point types, do a good job of decimal control. For example, if there are 4 decimal places, you cannot enter 5 decimal places, and can only enter 4 decimal places at most.

[0120] Please make relevant checks when inputting special rules. If the segment number can only be entered from 1 to 9, other numbers cannot be entered.

[0127] And, the data processing includes one or more of adding, deleting, modifying and querying;

[0128] The processing module is also used to report the determined second operating mode to the overall regulating point through each of the intermediate regulating points, and to enable the overall regulating point to splice the second operating modes of each of the intermediate regulating points to determine the target operating mode.

[0129] As an optional implementation manner, the topology condition includes:

[0130] Determine whether the lines of each of the subordinate modes have an intersection with the main mode, and if there is an intersection, take the line corresponding to the main mode as the first target line;

[0131] It is determined whether there is an intersection between the lines of each subordinate mode. If there is an intersection, the lines are overwritten according to the order in which the data of each subordinate mode is stored in the database, and the line corresponding to the newly stored subordinate mode is used as the second target line.

[0132] This implementation is based on the line distribution between the main mode and each slave mode, and determines whether there is a line intersection between the modes according to the preset topological conditions, and performs corresponding data coverage or data selection when there is a line intersection. Specifically, when there is an intersection, it is covered according to the principles of main mode priority and latest data priority, avoiding splicing failure caused by data duplication in the splicing process, thereby improving the effectiveness and efficiency of the target operation mode splicing process.

[0133] As an optional implementation, the processing module is further configured to, before performing mode splicing on the master mode and each of the slave modes according to the splicing condition to determine the target operation mode,

[0134] Determine the method data conditions;

[0135] If it is determined that each of the second operating modes meets the mode data condition, the second operating modes of each of the intermediate adjustment points are spliced ​​to determine a target operating mode.

[0136] In this embodiment, before the general adjustment point splices the second operating modes uploaded by each intermediate adjustment point, it first determines the mode data conditions to limit the data validity of the second operating mode, thereby verifying whether each second operating mode meets the corresponding mode data conditions. Only when the second operating mode data is complete and the data format, equipment and line conditions meet the preset requirements can the mode splicing be performed to determine the target operating mode, thereby improving the effectiveness of the target operating mode splicing process.

[0137] As an optional implementation, the mode data condition includes one or more combinations of the following:

[0138] The number of the second operating modes is within a preset range;

[0139] The data in each of the second operation modes conforms to a preset format;

[0140] Each of the second operating modes meets the verification condition.

[0141] This embodiment determines the mode data conditions of the second operating mode, determines whether the number and data format of the second operating modes meet the preset requirements, and determines whether the substantive content of each of the second operating modes is valid through preset verification conditions, thereby ensuring the effectiveness of the second operating mode and improving the effectiveness of the target operating mode splicing process.

[0142] As an optional implementation manner, the processing module performs the judgment process of the verification condition specifically including:

[0143] It is determined whether the target areas corresponding to the second operating modes have any intersection. If the target areas corresponding to the second operating modes do not have any intersection, the verification condition is met.

[0144] In actual applications, this embodiment determines whether the target areas corresponding to the second operating modes uploaded by each central adjustment have an intersection. If there is no intersection, it means that the data is valid and meets the verification conditions. Therefore, the validity of the data is restricted from the target area corresponding to the second operating mode, thereby improving the effectiveness of the target operating mode splicing process.

[0145] As an optional implementation manner, the processing module performs the judgment process of the verification condition further comprising:

[0146] A power flow calculation is performed for each of the second operating modes. If the power flow calculation results of each of the second operating modes converge, the verification condition is met.

[0147] In actual applications, this embodiment determines whether the power flow calculation results corresponding to the second operating mode uploaded by each central control are converged. If the power flow calculation results of each second operating mode are converged, it means that the data is valid and meets the verification conditions. Therefore, the validity of the data is restricted based on the essential content of the second operating mode, thereby improving the effectiveness of the target operating mode splicing process.

[0148] As an optional implementation manner, the processing module performs the judgment process of the verification condition further comprising:

[0149] It is determined whether the second operating mode data corresponding to each of the intermediate adjustment points have been submitted to the overall adjustment point. If the second operating mode data corresponding to each of the intermediate adjustment points have been submitted to the overall adjustment point, the verification condition is met.

[0150] In actual applications, this embodiment determines whether the second operating mode uploaded by each intermediate adjustment has been completely uploaded. If it is completely uploaded, it means that the data is valid and meets the verification conditions. Therefore, the validity of the data is restricted from the data integrity corresponding to the second operating mode, thereby improving the effectiveness of the target operating mode splicing process.
