Description

Technical Field

[0001] The present invention relates to the technical field of power supply protection for important places, and in particular to a method for safe power supply protection for important places based on a topological structure. Background Art

[0002] The power operation guarantee command platform plays a vital role in the reliable power supply of the guarantee objects and the smooth implementation of power supply guarantee work. The relevant data of power supply guarantee for major events include various types such as power grid information, event competitions, venue energy, and urban operation. During the power supply guarantee period of the World Internet Conference, there was no unified system platform support. Passive methods such as manual squatting, mobile emergency communication, and 3G mobile video were used, which could only be done after the event, and real-time monitoring, pre-judgment, and unified on-site dispatch and command could not be achieved; the emergency communication channel was single and there was no reliable backup channel. The dispatch flexibility and accuracy of the traditional power supply guarantee system are poor, which is not convenient for real-time monitoring of all the various and large number of power supply guarantee equipment in power supply guarantee; and the power supply equipment in different subsystems has different functions and names, making it difficult to accurately control the status of each power supply equipment during the power supply guarantee process.

[0003] For example, a "composition method, device and storage medium of a panoramic information model of power supply security for a venue" disclosed in a Chinese patent document, with the announcement number: CN117034509A, discloses the following steps: obtaining a main grid system model, a distribution grid system model, and a venue power supply system model; splicing the main grid system model, the distribution grid system model and the venue power supply system model to obtain a power grid topology model; obtaining power supply models and data information corresponding to the internal business system, the external business system and the operating environment of the power grid system, as well as a three-dimensional information model of the target venue; associating the power supply model, the corresponding data information and the three-dimensional information model with the grid topology model, respectively, to obtain a panoramic information model of power supply security. However, this solution does not take into account the problem that the working status of the power supply equipment in the system is not accurate enough due to the complex and numerous power supply tasks in the power supply process. Summary of the invention

[0004] In order to solve the problem that the power supply protection process control of important places in the prior art is not accurate and efficient enough, the present invention provides a method for safe power supply protection of important places based on topological structure, which can establish a power supply protection path in combination with the topological path and evaluate the status of the power supply protection equipment, thereby improving the reliability of power supply protection.

[0005] In order to achieve the above object, the present invention provides the following technical solutions: A method for safe power supply in important places based on topological structure, comprising the following steps; Detecting the position information in the power conservation instruction, and establishing the power conservation path according to the position information in the power conservation instruction; The topological power supply path is modeled in combination with the point cloud data of the venue to obtain the power supply path model; Determine whether the power-saving device is in the power-saving path model, and if so, add the power-saving device to the power-saving device group; When the power protection equipment group is constructed, power protection is performed according to the power protection equipment group; Perform topology analysis on the power protection equipment group and calculate the power protection range based on the current topology relationship and real-time status; Obtain the safety index corresponding to the power protection range, and evaluate each power protection device according to the safety index. First, obtain the power protection instruction, determine the power protection path according to the power protection instruction, and determine the power protection path model based on the power protection path combined with the three-dimensional point cloud model; then verify and distinguish the power protection equipment according to the power protection path model, determine the power protection range of the distinguished power protection equipment, determine the output of the power protection equipment within the power protection range and evaluate it. Accurately obtain the power protection effect and efficiently control the power protection equipment.

[0006] Preferably, the topological power-saving path is modeled in combination with the point cloud data of the venue, including each power equipment and connection relationship in the topological power-saving path; the point cloud data of the venue is obtained, and the part about the topological path in the point cloud data is screened for three-dimensional modeling. Determine all the power equipment and connection relationships in the power-saving path to form a topological path. At this time, the power-saving path includes power equipment that does not exist in the original power-saving instructions; obtain point cloud data inside and outside the venue and the main network and distribution network, perform feature matching on the point cloud data and the topological path to identify, obtain the point cloud data of the topological path, and model the point cloud data of the topological path to obtain a three-dimensional model of the topological path. Each topological power-saving path can be three-dimensionally modeled separately, without the need to call all the point cloud data, which greatly reduces the amount of data processing.

[0007] Preferably, when performing three-dimensional modeling on the topological path in the filtered point cloud data, the position information and structural information in the point cloud data are separated; the position information is filtered according to the topological path, and the structural information corresponding to the position information is filtered according to the power equipment in the topological path. The position of the topological path is determined by comparing the position information in the point cloud data with the topological path; the structural information in the point cloud data that conforms to the topological path is filtered at the determined position information, thereby determining the position information and structural information of the power equipment in the topological path in the three-dimensional model. The power protection path obtained in the power protection instruction can be three-dimensionally modeled.

[0008] Preferably, before detecting the position information in the power conservation instruction, the method includes obtaining the power conservation instruction of the dispatching system, the power conservation instruction includes regular instructions and time instructions, and the time instructions perform the power conservation task; only the regular instructions are detected. The dispatching system continuously issues regular instructions and time instructions, the regular instructions are determined according to the daily power conservation plan, the regular instructions are fixedly sent according to the daily power conservation plan, and the time instructions are dynamically generated and randomly sent according to the real-time power conservation task. Temporary power conservation tasks and real-time power conservation tasks are performed through time instructions, and planned power conservation tasks are performed through regular instructions. Regular instructions include multiple groups, each group of regular instructions includes no less than one power conservation task, and the same power conservation task is sent at least once through at least one regular instruction. The power conservation task can be detected and confirmed according to the operation status of the dispatching system.

[0009] Preferably, when adding the power protection device to the power protection device group, the unique identification code of the power protection device is obtained, and the traceability data of the corresponding power protection device is obtained according to the unique identification code. Each power protection device has its own corresponding unique identification code, and the unique identification code represents the different functions and names of each power protection device in different subsystems. Each power protection device has only one unique identification code, and the unique identification code includes multiple groups of characters, each group of characters represents the name in a subsystem, and each group of characters has three levels of grouping, and the three levels of grouping represent the functions in the subsystem; so that all devices can be accurately identified to avoid device confusion. The traceability data corresponding to the device is obtained through the unique identification code, so that multiple power protection devices in the same position do not interfere with each other.

[0010] As a preferred embodiment, the power protection according to the power protection equipment group includes: determining the power protection task according to the power protection equipment in the power protection equipment group, generating the power protection instruction according to the power protection task; and continuously detecting the generated power protection instruction. Obtain information such as the function and connection relationship of the power protection equipment in the power protection equipment group, so as to determine the power protection task that the power protection equipment in the power protection equipment group can achieve, and then determine the corresponding power protection instruction, which is sent in the form of a time instruction. At the same time, all power protection instructions are detected, wherein the power protection instruction generated by the power protection equipment group generates the same power protection equipment group again after detection, which essentially completes the confirmation of each power protection equipment in the power protection equipment group. After confirming the power protection equipment group, the power protection task is sent in the form of a time instruction to execute the corresponding power protection task. It is possible to confirm the power protection equipment in the power protection task multiple times, confirm whether there is a faulty or redundant power protection equipment in each power protection task, and then ensure the accuracy of the power protection equipment in each power protection task, ensure the efficient control of the power protection task, and improve the safety and reliability of the power protection process.

[0011] Preferably, the calculation of the power supply protection scope includes determining the GIS area covered by the power supply protection task and determining the scope of influence of the operation of the main network and distribution network in the covered GIS area. Obtain GIS data, which includes the area covered by all power supply protection equipment; determine the area covered by the power supply protection task according to the GIS data corresponding to the power supply protection equipment in the power supply protection task, determine the operation status of the main network and distribution network in the area covered by the power supply protection task, and determine the actual coverage of the operation status of the main network and distribution network. The power supply protection scope of each power supply protection task can be determined, which is convenient for determining the power supply protection scope of the power supply protection task and adjusting the power supply protection process according to the power supply protection scope of each power supply protection task.

[0012] Preferably, after the operation impact range is determined, the power supply situation is determined, and the operation impact range is divided into a power protection range and a comparative calculation area according to the power supply situation. The power supply situation of each line and branch within the power protection range is determined, and the power supply situation of the power protection target within the power protection range is determined; a power supply situation threshold is set, and the power protection range is divided according to the power supply situation threshold, and the part of the operation impact range except the power protection range is set as the comparative calculation area; the power protection effect is determined by comparing the calculation area and the power protection range. The actual impact on the power protection process in the power protection task can be determined, and the actual power protection effect in the power protection task can be determined, which is convenient for evaluating the power protection task.

[0013] As a preferred method, after determining the comparison calculation area, the safety index of the comparison calculation area is obtained as standard data, and the influence relationship between the safety index and each power protection equipment is determined based on the standard data. By using the safety index of the comparison calculation area as relatively poor standard data, the influence relationship of the equipment with poor power protection effect on the safety index is determined; the power protection equipment whose power protection effect does not meet expectations during the power protection process is analyzed, and each power protection task is evaluated in multiple dimensions.

[0014] As a preferred method, a power protection equipment database is established, in which traceability data of power protection equipment is stored, and the traceability data includes location data and status data. All power protection equipment data is stored in the power protection equipment database, which improves the security of the power protection equipment data and enables the traceability data of the power protection equipment to be stored separately from the power protection process of the dispatching system.

[0019] The following is an explanation of the implementation methods of the present invention through specific embodiments. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figure 1-2 As shown, in a preferred embodiment, the present invention discloses a method for safely maintaining power supply in important places based on topological structure, comprising the following steps; Detecting the position information in the power conservation instruction, and establishing the power conservation path according to the position information in the power conservation instruction; The topological power supply path is modeled in combination with the point cloud data of the venue to obtain the power supply path model; Determine whether the power-saving device is in the power-saving path model, and if so, add the power-saving device to the power-saving device group; When the power protection equipment group is constructed, power protection is performed according to the power protection equipment group; Perform topology analysis on the power protection equipment group and calculate the power protection range based on the current topology relationship and real-time status; Obtain the safety index corresponding to the power protection range and evaluate each power protection equipment according to the safety index.

[0021] First, a power protection instruction is obtained, in which a power protection task and corresponding multi-level power protection equipment are provided. A power protection path is determined according to the location information of the multi-level power protection equipment in the power protection instruction, and the power protection path passes through multi-level main networks and distribution networks.

[0022] The power supply protection path is topologically analyzed to determine the power grid equipment to which the power supply protection command is transmitted. The power grid equipment includes primary equipment, secondary equipment, auxiliary control equipment, poles, towers, station buildings and other equipment nodes.

[0023] Obtain the point cloud information of the venue, perform 3D modeling of the venue based on the point cloud information of the venue, and perform 3D modeling of the power equipment inside and outside the venue. The point cloud information includes the structural information and location information of the building and equipment.

[0024] After modeling based on the point cloud information, the three-dimensional models of the various areas and equipment that make up the power protection path are extracted, and a three-dimensional model of the power protection path is established based on these three-dimensional models.

[0025] All three-dimensional models of power protection paths are traversed, and if the electric power equipment is located in the three-dimensional model of the power protection path, the power protection equipment is added to a power protection equipment group.

[0026] The construction status of each power protection equipment group is detected in real time, and when the power protection equipment group can complete a power protection task, it is determined that the construction of the power protection equipment group is completed.

[0027] After the power protection equipment group is constructed, the power protection task is executed according to the power protection equipment group, and the power protection signal corresponding to the power protection equipment group is sent to the power protection equipment in the power protection equipment group.

[0028] The power protection equipment group is topologically analyzed to obtain a connection relationship diagram of the power equipment therein, and the actual working status of each power equipment in the power protection equipment group is obtained. The actual power protection range of the power protection equipment group is obtained based on the connection relationship diagram and the actual working status.

[0029] The actual safety indicators are determined for the power supply protection range. The safety indicators include the protection effect of the power supply protection range corresponding to different protection stages, the voltage level, protection level, fault optimization effect, etc. corresponding to the power supply protection range.

[0030] The safety index is the sum of the optimized outputs of all power equipment under the overall plan. Each power equipment in the power protection equipment group is evaluated according to the safety index to determine the actual output level of each power equipment during the power protection process.

At the same time, it can improve the actual output of power equipment during the power protection process, reduce the redundancy of the system, and improve the stability of the power protection system.

[0034] In other embodiments, when determining the power protection device, three-dimensional data of the power protection device is obtained and compared with the three-dimensional data of the power protection path. If the power protection device is in the power protection path, the power protection device is added to the power protection device group.

[0035] In other embodiments, the power protection equipment group includes a plurality of character groups stored in a system server, each character group includes at least one character combination, wherein specific character combinations represent different power protection tasks.

[0036] When in use, the system center obtains the characters of the corresponding power equipment from each cloud node, and the characters include the basic information of the corresponding power equipment. Different character combinations representing different power protection tasks are pre-stored, and the power protection equipment group is detected according to the pre-stored character combinations. When the character combination in the power protection equipment group is the same as at least one of the pre-stored character combinations, the power protection equipment group is completed and no power equipment is added.

[0037] In other embodiments, when a character combination of a power protection task exists in the power protection equipment group, a necessity check is performed on the remaining equipment in the power protection equipment group to distinguish between power equipment that completes the corresponding power protection task and power equipment that is unnecessary for the power protection task, and only the power that completes the corresponding power protection task is controlled to provide power protection.

[0038] In other embodiments, in the constructed power equipment group, the character group includes different character combinations of multiple power protection tasks, and the power protection equipment in the power equipment group is controlled according to different power protection tasks. The control order is determined by the safety index of each power protection range, and the power protection tasks with high safety index are controlled first.

[0040] When in use, the planned power supply scope is added to or deleted based on the power supply situation, and the actual power supply situation in various locations within the planned power supply scope is determined. The area within the planned power supply scope where the actual power supply situation is the best is taken as the power supply scope, and the remaining areas within the planned power supply scope are taken as comparison and calculation areas for safety indicators.

[0041] In other embodiments, when obtaining the safety index corresponding to the power supply protection range, a comparative safety index is calculated for the remaining areas within the planned power supply protection range, and the protection effects of different protection stages in the power supply protection range are determined based on the comparative safety index, as well as the voltage level, protection level, fault optimization effect, etc. corresponding to the power supply protection range.

Determine the score of the power protection equipment within the power protection range based on the influence relationship. Evaluate the power protection equipment based on the score and the safety index of the power protection range.

[0043] When in use, the safety index calculation is performed on the planned power protection range, and the calculation results are divided into power protection areas and comparative calculation areas; the correlation matrix between the calculation results of the comparative calculation area and the power protection equipment status within the comparative calculation area is determined. Each power protection equipment has its own correlation matrix.

[0044] The power protection equipment in the power protection area and the comparison calculation area are matched according to the equipment type, and the score of the power protection equipment in the power protection area is determined according to their respective association relationship matrices. The score corresponds to the safety index. The power protection equipment in the power protection area is evaluated according to the difference between the score and the safety index. When the difference exceeds the threshold N, the safety of the power protection equipment is judged to be high. When the difference is less than N2, the power protection equipment is judged to be unstable.

Each power protection device has only one unique identification code, which includes multiple groups of characters, each group of characters represents the name in a subsystem, and each group of characters has three levels of grouping, which represents the functions in the subsystem.

[0050] When in use, unique identification codes including Axxxbbb.M are stored in the power supply command center library of the dispatching system.

[0051] In other embodiments, the power protection according to the power protection equipment group includes: determining the power protection task according to the power protection equipment in the power protection equipment group, generating the power protection instruction according to the power protection task; and continuously detecting the generated power protection instruction.

[0052] When in use, the information such as the functions and connection relationships of the power-saving devices in the power-saving device group is obtained, so as to determine the power-saving tasks that can be achieved by the power-saving devices in the power-saving device group, and then determine the corresponding power-saving instructions, which are sent in the form of time instructions. At the same time, all power-saving instructions are detected, and the power-saving instructions generated by the power-saving device group regenerate the same power-saving device group after detection, which essentially completes the confirmation of each power-saving device in the power-saving device group. After confirming the power-saving device group, the power-saving task is sent in the form of a time instruction to execute the corresponding power-saving task.

[0053] When the power conservation instruction forms only one power conservation equipment group, the power conservation tasks in the power conservation equipment group are directly executed.

[0054] When multiple power protection equipment groups are formed in the power protection instruction, the power protection tasks in the power protection equipment groups are executed in sequence according to the sizes of the power protection equipment groups.

[0055] When there are still unclassified power protection devices in the power protection instruction or they do not constitute at least one power protection device group, the power protection instruction is not executed.

[0056] In other embodiments, the calculation of the power supply protection scope includes determining the GIS area covered by the power supply protection task and determining the impact scope of the main network and distribution network operation in the covered GIS area.

[0062] In other embodiments, after the comparison calculation area is determined, the safety index of the comparison calculation area is obtained as standard data, and the influence relationship between the safety index and each power protection device is determined according to the standard data.

[0063] When in use, the safety index of the calculation area is compared as relatively poor standard data to determine the influence of equipment with poor power protection effect on the safety index.

[0064] Then, the virtual safety index of the power protection equipment within the power protection range is determined according to the influence relationship obtained above, and the reliability of each power protection equipment is determined by comparing the difference between the virtual safety index and the safety index.

[0068] After the power protection device is added to the power protection device group, when the power protection device group is topologically constructed, only the power protection devices in the power protection device group are topologically constructed, and other power devices are not topologically constructed. At this time, the topological model is the actual power protection path, and the safety index is verified according to the power protection path, and the power protection devices in the actual power protection path are verified.

[0069] After determining the power equipment in the comparison calculation area, the comparison calculation area will be used as the target area for other power protection tasks, and the power protection equipment in it will be used as available equipment for other power protection tasks. The equipment within the power protection range will be used as high-security power protection equipment and will not be used as the target area for other power protection tasks.
