The CIM file is a file containing the above information. The problems of the power distribution network structure can be comprehensively determined based on the CIM file. The CIM file may be a file in a GIS (Geographic Information System), and a GIS (production management integrated Information System) is a production management integrated Information System that connects power equipment, a substation, a power transmission and distribution network, a power consumer, a power load, and the like of a power enterprise to form power informatization.

Key nodes (nodes on two sides of automatic switch equipment in a line) are searched in the line between a node of a tie switch close to a transformer station side and a node of an outgoing line switch of a transformer substation close to the transformer station side, the key nodes are numbered, and a main line node corresponding to a transformer in the line is determined according to the number of the key nodes (the nodes in the line between the node of the tie switch close to the transformer station side and a first node are main line nodes) so as to determine the line where the transformer is located and the road section of the line where the transformer is located, and therefore the number of the transformers and the number of users in each road section in the line are determined.
Specifically, if it is determined that the number of transformers in any road segment in the line exceeds the corresponding preset transformer number threshold and/or the number of users in any road segment in the line exceeds the corresponding preset user number threshold, it indicates that the line is unreasonable in section, and at this time, it may be determined that the line is unreasonable in section and prompt information that the line is unreasonable in section is sent out to prompt relevant workers to take corresponding measures in time.

Example two
Fig. 2 is a flowchart of a method for determining the segment rationality of a power distribution network frame according to a second embodiment of the present invention, where the second embodiment is applicable to a case of determining the segment rationality of the power distribution network frame, the method may be executed by a device for determining the segment rationality of the power distribution network frame, the device may be integrated in a system for determining the segment rationality of the power distribution network frame, and the method specifically includes the following steps:
And step 220, determining a first node on each transformer substation connecting line in the power distribution network frame according to the CIM file data.
The first node is a node of an outgoing line switch of the transformer substation close to the transformer substation side. The types of the nodes can be determined according to different characteristic fields of each node in the line, and the types of the nodes comprise a first node, a father node, a child node, a main line node, a non-main line node, a tail end node, a key node, a non-key node and the like. And searching the outgoing switch of the transformer substation through the characteristic field to obtain the ID of the outgoing switch, and finding the front end node of the outgoing switch through the characteristic field under the ID of the outgoing switch, wherein the node is the first node. The specific process of determining the first node is as follows: and determining the result as the outlet switch of the transformer substation by searching a field of < cim, power system resource, PSRType rdf, resource ═ PSRTYPE _140,/> and acquiring that the outlet switch ID is 'transformer substation switch ID' (the actual transformer substation outlet switches are different and the codes are also different). And if the < cim: Terminal rdf: ID ═ TERMINAL _ substation switch ID _1 '> is found, the < cim: terminal.ConnectivityNode rdf: resource ═ # NODE _ NODE ID'/>, the ID of the front end NODE of the substation outlet switch is "# NODE _ NODE ID", and the NODE is the first NODE on the substation connecting line.
And step 230, based on a tree table lookup algorithm, looking up each node in the substation connecting circuit by taking the first node as a starting point to determine the connection relation of each node and generate a topological relation table.
Specifically, a < cim: Terminal rdf: ID ═ Terminal _ device ID _1 > is used as a front-end NODE of the device, and a < cim: Terminal rdf: ID ═ Terminal _ device ID _2 > is used as a back-end NODE of the device, and a < cim: terminal.connectitvynode rdf: resource ═ NODE ID "/> field is found under the two items, so that device front-end and back-end NODE IDs are obtained. The topological relation can be analyzed according to the connection relation of the front end node and the rear end node of the equipment, so that the first node starts to search, the topological relation of each node in the connecting line of the transformer substation is obtained, and a topological relation table is generated, wherein the topological relation table comprises but is not limited to the connection relation of the front end node and the rear end node of the equipment, the nodes on two sides of the connecting equipment and the like.
And 240, determining a tie switch in the transformer substation connecting line according to the topological relation table.
The interconnection switch is a switch associated with at least two lines, and the switch associated with at least two lines may be a switch in which a line in which a node at one end of the switch is located is different from a line in which a node at the other end of the switch is located. If the fields of "< cim: switch.isring > true" and "< cim: power system resource.owenership > 1" are searched, the device with the fields simultaneously existing at the target is determined as the tie switch.
And step 250, based on a sequence searching algorithm, searching the nodes of the interconnection switches close to the transformer substation side step by step in a reverse sequence by taking the interconnection switches as starting points until the first node in the transformer substation connecting line is searched.
The first node is a node of an outgoing line switch of the transformer substation close to the transformer substation side. And searching front end nodes of the interconnection switches, namely nodes of the interconnection switches close to the transformer substation side, in a reverse sequence step by taking the interconnection switches as starting points until a first node in a transformer substation connecting circuit is searched, marking all nodes under the path as main line nodes, forming a main line by the main line nodes, and using other nodes outside the main line nodes as non-main line nodes.
And step 260, searching a key node in a line between the node of the tie switch close to the transformer station side and the first node, and numbering the key node.
The key nodes are nodes on two sides of automatic SWITCH equipment in a line, the key nodes can be searched on a main line, and if fields of < cim and equipment type rdf, ID, SWITCH _ equipment ID >are searched on the main line, and the equipment type is non-Breaker or LoadBreakSwitch, the nodes on two sides of the equipment are determined to be the key nodes. The device class defined in the CIM file may include "Breaker" and "loadbreak switch," and the device class is determined by looking up the corresponding field. The key nodes are arranged in a reverse order to carry out sectional numbering, namely, the sectional numbering is carried out from far to near according to the distance from the key nodes to the transformer substation, and the specific numbering can be 1, 2, 3, 4.
And 270, determining a main line node corresponding to the transformer in the line according to the number of the key node so as to determine the line where the transformer is located and the road section of the line in the transformer substation connection line.
And all nodes in a line between a node of the tie switch close to the transformer station side and the first node are main line nodes. "TransforrmeWindingType > primary" and "< cim: TransforrmeWindingrdf can be found: the ID is "wind _ transformer ID", and the device with the above fields is determined as a transformer. And performing reverse-order searching by using a sequence searching algorithm and taking the transformer as a starting point until the searched node is a key node, namely determining the main line node of the transformer, and determining the section of the transformer, namely the line where the transformer is located and the road section of the line where the transformer is located.
And step 280, determining the number of transformers and the number of users in each section of the line based on the line where the transformers are located in the transformer station connecting line and the sections of the line where the transformers are located.
Specifically, when the line where each transformer is located in the transformer substation connection line and the section of the line where the transformer is located are determined, the sum of the transformers in a certain section can be used as the number of the transformers in the section, and correspondingly, the sum of the number of users corresponding to the transformers in the certain section can be used as the number of the users in the section.
And 290, comparing the number of transformers on each road section in the line with a corresponding preset transformer number threshold value, comparing the number of users on each road section with a corresponding preset user number threshold value, and when the number of transformers on any road section in the line exceeds the corresponding preset transformer number threshold value and/or the number of users on any road section in the line exceeds the corresponding preset user number threshold value, determining that the line is unreasonable in section and sending out prompt information.
Specifically, if it is determined that the number of transformers in any road segment in the line exceeds the corresponding preset transformer number threshold and/or the number of users in any road segment in the line exceeds the corresponding preset user number threshold, it indicates that the line is unreasonable in section, and at this time, it may be determined that the line is unreasonable in section and prompt information that the line is unreasonable in section is sent out to prompt relevant workers to take corresponding measures in time.
It should be noted that specific values of the preset transformer quantity threshold and the preset user quantity threshold may be specifically set according to actual conditions, and specific values of the preset transformer quantity threshold and the preset user quantity threshold in different road sections may be different, which is not limited herein.
And 291, generating a data table and displaying and outputting the data table based on the determined number of the transformers and the number of the users of each section in the line.
The data table comprises the number of transformers and the number of users of each road section in the circuit and unreasonable road sections, wherein the number of transformers exceeding the corresponding preset transformer number threshold value and the number of users exceeding the corresponding preset user number threshold value in the circuit can be marked in different fonts or colors and the like, the data table is displayed, relevant workers can conveniently and visually observe the number of transformers and the number of users of each road section, and therefore the workers can know the conditions of each road section. Through outputting the data table, related personnel can extract different data according to actual requirements, and requirements of planning personnel are fully met; the data in the data table can also be used for line automation segment number calculation, automation segment user number calculation and the like, and the expanded application range is wide.
The method for judging the piecewise rationality of the power distribution network frame provided by this embodiment generates a topological relation table of each substation connection line in the power distribution network frame according to the obtained CIM file data, thereby determining a line where a transformer in the substation connection line is located and a section of the line where the transformer is located based on the topological relation table, determining the number of transformers and the number of users in each section of the line, comparing the number of transformers in each section of the line with a corresponding preset transformer number threshold, comparing the number of users in each section of the line with a corresponding preset user number threshold, determining that the line is in unreasonable piecewise form and sending out prompt information when the number of transformers in any section of the line exceeds the corresponding preset transformer number threshold and/or the number of users in any section of the line exceeds the corresponding preset user number threshold, based on the determined number of transformers and the number of users in each section of the line, and generating a data table and displaying and outputting the data table. Compared with the conventional method for judging the section rationality of the power distribution network frame, the method for judging the section rationality of the power distribution network frame provided by the embodiment determines the number of transformers and the number of users in each road section in a line according to a line topology relation table generated by CIM file data, automatically determines whether the line section is reasonable or not according to the number of the transformers and the number of users in each road section in the line, does not need manual assistance, can quickly and efficiently determine the problem of the line structure of the power distribution network frame, and avoids wrong judgment of the section rationality caused by errors in manually collected information, so that the reliability of the judgment of the section rationality is improved, and the power supply reliability of the power distribution network frame is improved; the data information which is fussy to read and judge is not needed to be manually read, and is displayed in an intuitive table form, so that the workload of planning personnel is greatly reduced, unreasonable lines of the net rack can be automatically analyzed, and the quality and the efficiency are synchronously improved; because a GIS user can continuously update input data, only the latest CIM file needs to be acquired, the latest CIM file data is calculated and then stored in a database, and the data is updated quickly; through outputting the data table, related personnel can extract different data according to actual requirements, and requirements of planning personnel are fully met; the data in the data table can also be used for line automation segment number calculation, automation segment user number calculation and the like, and the expanded application range is wide.
