Description

Technical Field

[0001] The present invention relates to the field of digitalization of power systems, and in particular to a method and system for maintaining a distributed transmission line diagram. Background Art

[0002] The single grid map is a visual representation of the geographical information of the power grid and an essential material for the operation and management of the power system. It is an inevitable requirement for the lean management of power system equipment to splice cross-provincial lines based on the headquarter's power grid resource business middle platform and display them on the single grid map of the headquarter. Due to the independence of data between different power grid provinces across the country, after the headquarter side completes the line synchronization, the same line may be disconnected between different power grid provinces, seriously violating the requirements of lean management of power system equipment. Summary of the Invention

[0003] Object of the Invention: The object of the present invention is to provide a method and system for maintaining a distributed transmission line diagram, which splices the independent line data between each power grid province across the country on the headquarter side.

[0004] Technical Solution: The method for maintaining a distributed transmission line diagram according to the present invention includes the following steps:

[0005] (1) The headquarter's power grid resource business middle platform obtains the set Pro of provincial main lines.

[0006] (2) A large container container for cross-provincial lines is established, and the elements in Pro associated with the container are matched and sorted.

[0007] (3) Each main line in Pro is traversed. The end device of the ProNth main line is GTN, and the starting device of the ProN+1th main line is GTN+1.

[0008] (4) A connection line between GTN and GTN+1 is created, the set Pro is updated, and the distributed transmission line diagram is updated according to the connection line and the set Pro.

[0009] Further, in the step (1), the headquarter performs data integrity verification on each main line and the equipment under the main line on the provincial side, and establishes a set of provincial main lines for the main lines synchronized from the provincial side to the headquarter.

[0010] Further, in the step (2), the headquarter determines whether the provincial container has been completed for splicing. The types of provincial containers that need to be spliced include lines and substations. If not, the headquarter side creates a large container container for cross-provincial lines. If it has been completed, the completed main line is recorded as the ProNth main line in the step (3).

[0011] Further, in the step (3), it is determined whether it is the splicing of the substation building and the main line. If so, the substation building is denoted as GTN, and the main line on the other end of the provincial side is denoted as the (ProN + 1)-th main line. Otherwise, each main line in Pro is traversed.

[0012] Further, in the step (3), according to the line name, voltage level and line nature of the container, the elements associated with the container in the set Pro are matched; the elements associated with the container in Pro are sorted, and according to the association relationship between the stored elements and the container.

[0013] Further, in the step (3), the topological information under the main line is found according to the resource id of the ProN-th main line and a topology is established, and the terminal number on the large-size side is obtained; the data corresponding to the operating pole tower is obtained according to the terminal number on the large-size side and is denoted as GTN;

[0014] The topological information under the main line is found according to the resource id of the (ProN + 1)-th main line and a topology is established, and the terminal number on the small-size side is obtained; the data corresponding to the operating pole tower is obtained according to the terminal number on the small-size side and is denoted as GTN + 1.

[0015] Further, in the step (4), if both the devices GTN and GTN + 1 are pole towers, a connecting line is created according to the coordinates and terminal numbers of the two pole towers;

[0016] If one of the devices GTN and GTN + 1 is a pole tower and the other is a substation building, all the devices under the substation building to which it belongs are found according to the switch at the end point, the terminal numbers are obtained and a topology is performed, and the outgoing line point connected to the switch is obtained; a connecting line is created according to the terminal number and coordinates of this outgoing line point and the terminal number and coordinates of this pole tower.

[0024] Beneficial effects: Compared with the prior art, the advantages of the present invention are as follows: First, the present invention completes the data synchronization of the provincial-side lines, and then associates the provincial-side lines with the large container of the cross-provincial lines created by the headquarters to ensure that there is an association relationship for each provincial-side cross-provincial line on the headquarters side. Then, the start and end devices to be spliced are found by using the methods of topological analysis and ledger query, and finally the splicing is completed, so as to complete the management of the cross-provincial lines on the headquarters side and avoid the problem of the disconnection of the cross-provincial lines in the distributed transmission line diagram.

[0026] Figure 2 is a flowchart of the distributed transmission line diagram maintenance method of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0028] The distributed transmission line diagram refers to the aggregation of transmission lines and the data of the devices under the lines of different management units, and the visual display thereof, including transmission devices such as lines, connecting lines, towers, and span sections, and is used to display the main network transmission grid structure in different regions. The distributed transmission line diagram of this embodiment is a single map of the headquarters' power grid.

[0029] As Figure 1 and Figure 2 shown, the distributed transmission line diagram maintenance method includes the following steps.

[0030] Step1: The headquarters synchronizes the provincial-side lines.

[0031] Step 1: Through the two-level penetration mechanism, the headquarters' power grid resource business middle platform obtains the tokens for authentication of each network province, connects to the Alibaba Cloud csb service bus, accesses the address of the provincial-side middle platform through csb, and obtains the permission to access the provincial-side middle platform through the token.

[0032] Step 2: Perform data verification on each main line and the devices under the main line to ensure the integrity of their data. The provincial-side main lines synchronized are called the set of provincial-side main lines under the cross-provincial main line, denoted as set Pro.

[0033] Step 2: Create cross-provincial line relationships.

[0034] Step 1: Based on the cross-provincial line relationship table, determine whether the provincial-side container has been completed. If not, based on the actual national situation, create the large cross-provincial line container container on the headquarters side, and then continue with the subsequent steps. If it has been completed, record the completed main line as ProN and enter Step 4, Step 2.

[0035] Step 2: Determine whether it is the splicing of the substation building and the main line. If not, continue with the subsequent steps. If so, record the substation building as GTN, and record the provincial-side main line at the other end as the (ProN + 1)-th main line, and enter Step 3, Step 3.

[0036] Step 3: According to the information such as the line name, voltage level, and line nature of the container, match the elements in set Pro that are associated with the container.

[0037] Step 4: Manually sort the elements in set Pro that are associated with the container, denoted as Pro1, Pro2, Pro3, etc.

[0038] Step 5: Based on the cross-provincial line relationship table model M (this model includes the following attributes: the current provincial-side segmented main line id, the id of the next segmented main line, the serial number of the current segmented main line, the id of the large cross-provincial line container to which it belongs), store the association relationships between the provincial-side main line elements such as Pro1, Pro2, Pro3, etc. and the container.

[0039] Step 3: Find the starting and ending devices of the adjacent provincial-side main lines.

[0040] Step 1: Traverse Pro, record the current provincial-side main line as ProN. According to the cross-provincial line relationship data, if ProN is the last segment under the cross-provincial main line, skip this main line. If it is not the last segment, enter Step 2.

[0041] Step 2: According to the resource id of ProN, find the information of all span segments, cable segments, and connecting lines under this provincial-side main line, obtain the terminal numbers of all span segments, cable segments, and connecting lines, perform topology on them. When topology reaches the end point, record the large-side terminal numbers S1, S2, S3, etc. at that point. According to the terminal numbers S1, S2, S3, find the corresponding data of the operating poles and towers, and record it as GTN.

[0042] Step 3: Find the terminal number on the small - size side of the main line according to the resource ID topology of ProN+1, and find the corresponding operating tower data according to the terminal number, denoted as GTN+1.

[0043] Step 4: If the topology fails to find, or when multiple eligible operating towers are found due to T - connection and data quality problems in the provincial - side middle platform, it is considered that the topology analysis fails. At this time, based on the general resource query of the headquarters middle platform, according to the resource ID whose affiliated main line is equal to Pro or ProN+1, and arranging according to the tower number as required, obtain all the operating tower information under the provincial - side main line, so as to find GTN and GTN+1 through manual confirmation.

[0044] Step4: Create a connection line and update the provincial - side main line ledger.

[0045] Step 1: Confirm whether it is a splicing between towers or between the outlet point of a tower and a substation according to its equipment type. When there is a switch at the end point, find all the equipment under the substation according to the substation to which the switch belongs, obtain its terminal number, and perform topology to obtain the outlet point connected to the switch. Create a connection line according to the terminal number, coordinates of this outlet point, and the terminal number and coordinates of the opposite - side tower; when both end - point devices are towers, directly create a connection line according to the coordinates and terminal numbers of the two towers.

[0046] Step 2: Update the resource ID of the superior main line of ProN and ProN+1 to be of the container type, and complete the splicing of the abnormal line.

[0047] Step5: After completing the creation of the connection, update the superior main line attribute of ProN, update the cache data of the headquarters power grid single - map, and complete the splicing of the cross - provincial line in the power grid single - map.

[0048] When there is a subsequent provincial - side line abnormality, for the spliced cross - provincial main line, match the corresponding container in the headquarters cross - provincial line relationship according to the resource ID of ProN or ProN+1, and update the superior line attribute of ProN or ProN+1 to the resource ID of the container, so as to complete the automatic splicing of the incremental abnormal line.
