Description

Technical Field

[0001] The present invention relates to the technical field of relay protection of power systems, and in particular to a method and system for constructing a virtual circuit verification rule base for an intelligent substation. Background Art

[0002] The substation configuration description (SCD) reflects the configuration connection relationship of the secondary equipment in the station with a virtual terminal loop. It is the bridge to realize the protection and control functions of the whole station. The correctness of the virtual loop of the configuration file will directly affect the accuracy and reliability of the protection and safety device action, equipment monitoring and control. Therefore, it is particularly important to ensure the correctness of the virtual terminal loop of the configuration file. With the rapid development of smart substation technology, the design, configuration and debugging methods of secondary equipment have changed significantly. As the key to realizing the protection and control functions, the correctness of the virtual terminal loop is crucial to the safe and stable operation of the smart substation.

[0003] The configuration files of smart substations involve many types of devices, a huge number of virtual circuits, and complex coupling relationships. Currently, they are mainly checked through manual review, debugging and verification. However, the on-site schedule is tight and the tasks are heavy, and the technical capabilities of the personnel are limited. There are common problems such as incomplete test items and inadequate verification of virtual circuits. Hidden dangers such as missing and wrong connections of virtual circuits have not been discovered in time. In recent years, there have been many incidents of incorrect protection action caused by virtual circuit problems in the configuration files of smart substations.

[0004] In view of the above problems, relevant domestic research institutes and equipment manufacturers have carried out research on the automatic verification of virtual circuits in smart substations. The mainstream technical solution is to compare the virtual circuit in the configuration file to be checked with the standard template. When the two are inconsistent, it is judged as an error, otherwise it is correct. However, after years of iterative development, the smart substation technology has many types, models, and versions of secondary equipment on site. There are differences in the virtual terminals of equipment from different manufacturers and different periods. At the same time, the connection of virtual circuits must also consider factors such as the voltage level of the substation and the primary main wiring method. The method of manually formulating standard templates has high technical requirements and a large workload. It is difficult to fully cover all kinds of working conditions, which has become a key problem restricting the engineering application of the automatic verification technology of virtual circuits in smart substations.

[0005] In summary, the development of a method for constructing a virtual circuit verification rule base for smart substations is of great significance for improving the safe and stable operation level of smart substations and reducing operation and maintenance costs and risks. Summary of the invention

[0006] The present invention aims to address the technical defects of the prior art and provide a method and system for constructing a virtual circuit verification rule base for a smart substation. The virtual circuit verification rule base for a smart substation is quickly constructed through sample learning, effectively solving the problems of incomplete virtual circuit verification rules in the current smart substation configuration file and large workload for manual establishment, reducing the risk of incorrect protection action caused by virtual circuit errors and improving the safety and stability of the power grid.

[0007] The first aspect of the present invention discloses a method for constructing a virtual circuit verification rule base for a smart substation, comprising the following steps:

[0008] Step 1, creating a smart substation virtual circuit verification rule model;

[0009] Step 2: Obtain a sample of the smart substation configuration file;

[0010] Step 3: parse the sample of the smart substation configuration file, extract the secondary equipment entity attribute labels and the relationship topology between the equipment;

[0011] Step 4, searching the smart substation virtual circuit verification rule database to see whether the extracted secondary equipment entity attribute labels and the relationship topology between the secondary equipment entities exist, and returning the search results;

[0012] Step 5, the search result response is, no rule creation is performed;

[0013] Step 6, if the search result is negative, the expert verifies the virtual circuit between the current secondary equipment entities;

[0014] Step 7, instantiating the virtual circuit verification rule model of the secondary equipment entity for which the search result responds to "no", and generating the virtual circuit verification rule between the secondary equipment with specific attributes.

[0015] Preferably, step 1 includes recording the entity attribute labels of secondary devices, the relationship topology between secondary devices, and the virtual circuit connections between secondary devices, automatically generating virtual circuit verification rules between devices with specific attributes, and inputting them into the virtual circuit verification rule database of the smart substation to generate a verification rule model, wherein the verification rule model includes the attribute labels of secondary devices on the receiving side and the sending side and the index of virtual terminals with connection relationships between secondary devices, virtual terminal descriptions, and circuits between virtual terminals.

[0016] Preferably, the secondary device entity attribute tag includes one or more combinations of a secondary device type attribute tag, a primary device type attribute tag to which the secondary device belongs, a secondary device manufacturer attribute tag, a secondary device model attribute tag, a secondary device software version attribute tag, a voltage level attribute tag of a primary device to which the secondary device belongs, and a main wiring mode attribute tag to which the secondary device belongs;

[0018] The primary equipment type attribute tags to which the secondary equipment belongs include lines, transformers, circuit breakers, busbars, reactors, bus tie circuit breakers, section circuit breakers, station transformers, and capacitors. The primary equipment type attribute tags to which the secondary equipment belongs can be defined and extended;

[0019] The voltage level attribute labels of the primary equipment to which the secondary equipment belongs include 1000kV, 750kV, 500kV, 330kV, 220kV, 110kV, 66kV, 35kV, and 10kV, and the voltage level attribute labels of the primary equipment to which the secondary equipment belongs can be defined and extended;

[0020] The main connection mode attribute labels of the primary equipment to which the secondary equipment belongs include single bus, single bus segment, double bus, double bus single segment, double bus double segment, three-half, inner bridge, and outer bridge. The main connection mode attribute labels of the primary equipment to which the secondary equipment belongs can be defined and extended.

[0021] Preferably, the process of extracting the secondary device entity attribute labels and the relationship topology between the secondary device entities in step 3 includes:

[0022] Step 3-1, parse the imported SCD file sample, and obtain the device name, description, model, manufacturer, and version attribute information list of all secondary equipment entities in the SCD file sample;

[0023] Step 3-2, according to the naming specification of intelligent electronic devices in smart substations, parse the names of physical devices of each secondary device respectively, and obtain the type of secondary device, the type of primary device to which the secondary device belongs, and the voltage level information of the primary device to which the secondary device belongs;

[0024] Step 3-3, parse the description of each secondary equipment entity, obtain the voltage level of the primary equipment to which the secondary equipment belongs, the type of primary equipment to which the secondary equipment belongs, the type of secondary equipment, and the secondary equipment set information, and proofread and supplement the secondary equipment entity attribute label extracted by parsing the secondary equipment entity device name;

[0025] Step 3-4, according to the information obtained by parsing the physical device name and device description of the secondary device, the primary device is matched and associated with the secondary device to which it belongs, the relationship topology between the primary and secondary devices is generated, and the secondary device is retrieved;

[0026] Step 3-5, parse the imported SCD file sample to obtain the physical virtual circuit connection network of the entire station secondary equipment;

[0027] Step 3-6, according to the generated relationship topology between the primary and secondary devices and the virtual circuit connection relationship between the secondary devices, determine the main wiring mode of the primary device to which the secondary device belongs;

[0028] Step 3-7, split the virtual circuit connection network of the entire station secondary equipment into multiple sub-networks in the format of "receiving end secondary equipment-sending end secondary equipment", and generate a relationship topology between secondary equipment entities.

[0029] Preferably, the retrieving of secondary devices in step 3-4 includes a first screening process and a second screening process;

[0030] The first screening process uses a Bloom filter to filter out completely incorrect device relationship topologies in the smart substation virtual circuit verification rule database; according to the generated secondary device entity relationship topology, the device set is G(d)={d1,d2}, and the information set of each device is D(i)=(i1,i2,…,i n ), the Bloom filter consists of a bit vector B = {B[1], B[2], ..., B[m]} and k hash functions hash(1), hash(2), ..., hash(k) with a mapping range of {1, 2, ..., m}. Each device calculates k hash functions to obtain k independent mapping positions, and sets the contents of these positions to 1 in the bit vector to store elements. The device search operation obtains k devices to be searched according to the hash function hash calculation. i The index value hash(d i ), check the value B[hash(d i )],if B[hash(d i )]=1, it indicates that the device belongs to the inter-device relationship topology, otherwise it does not belong to the inter-device relationship topology, and the inter-device relationship topology set T1=(G(1), G(2), …, G(i), …, G(n)) containing device d1 in the virtual circuit verification rule database is obtained. The Bloom filter is continued to be used for secondary screening in the inter-device relationship topology set T1=(G(1), G(2), …, G(i), …, G(n)) to obtain the inter-device relationship topology set T2=(G(1), G(2), …, G(i), …, G(m)) containing both device d1 and device d2, where m≤n;

[0031] The second screening process is based on the matching of the global clustering coefficient of the topology, and obtains the unique relationship topology between the secondary device entities from the device relationship topology set T2 = (G(1), G(2), ..., G(i), ..., G(m)) obtained in the first screening process. The global clustering coefficient of the relationship topology set G(i) (G(i)∈T) between devices is equal, where the global clustering coefficient C of the relationship topology is:

[0032]

[0033] Where n represents the number of devices in the relationship topology, n = 2; v i represents the i-th device; V represents the node set, that is, V = v1, v2, ..., v n );C vi represents the individual clustering coefficient of the ith device; T Vi Indicates that the device (v i The vector value of the virtual circuit between adjacent devices, that is, the difference between the number of receiving virtual circuits and the number of sending virtual circuits; K Vi Indicates that in the relationship topology with the device v i The sum of the number of virtual circuits that exist.

[0034] Preferably, in step 4, according to the extracted secondary device entity attribute tags and the relationship topology between the devices, the receiving-end secondary device entity attribute tags are input into the receiving-end secondary device of the smart substation virtual circuit verification rule database, the corresponding secondary device is retrieved, and the sending-end secondary device entity attribute tags are input into the sending-end secondary device in the above search results, and then the search is performed. If both the receiving-end and sending-end secondary device entities are retrieved and exist, the search result output is yes; if one or both of the receiving-end and sending-end secondary device entities are retrieved and do not exist, the search result output is no;

[0035] In step 5, the search result response is that it indicates that the virtual circuit verification rule between the secondary device entities currently searched already exists, and no rule creation is performed;

[0036] In step 6, if the search result responds to "no", it is marked with a certain color or symbol, indicating that the virtual circuit verification rule between the secondary equipment entities currently searched does not exist. The expert manually verifies the virtual circuit between the current secondary equipment entities. If the current virtual circuit is incorrect, the expert improves it to ensure that the virtual circuit is connected correctly.

[0037] Preferably, in step 3-4, according to the number of the primary device to which the secondary device belongs obtained by parsing the physical device name of the secondary device, the secondary devices with the same number are associated with the same primary device, indicating that such secondary devices belong to the same primary device, and according to the name of the primary device to which the secondary device belongs obtained by parsing the physical device description of the secondary device, the secondary devices with the same primary device name are associated with the same primary device, indicating that such secondary devices belong to the same primary device.

[0038] Preferably, in the steps 3-6, the number of bus segments is determined by the number of bus voltage transformers configured, and then the main connection mode of the bus is determined according to the number of segmentation and bus-connecting primary devices.

[0039] The second aspect of the present invention discloses a system for constructing a virtual circuit verification rule base for a smart substation, comprising:

[0040] Data server, used for storage and management of virtual circuit verification rules of smart substations;

[0041] The application terminal is used to establish a verification rule model, parse configuration file samples, visualize configuration file virtual circuits and other information, and interact with the data server.

[0042] Preferably, the application terminal includes:

[0043] Model creation module, used to create a virtual circuit verification rule model for smart substations and define secondary equipment attribute labels and data formats;

[0044] The file parsing module is used to obtain and parse the sample of the smart substation configuration file, extract the secondary equipment entity attribute labels and the relationship topology between the equipment;

[0045] A rule retrieval module is used to retrieve secondary equipment entity attribute labels and relationship topology between secondary equipment in the intelligent substation virtual circuit verification rule database;

[0046] Visualization module, used to display the configuration file of the smart substation, including the secondary equipment information list, the virtual terminal index of the secondary equipment, the virtual terminal description and the link between the virtual terminals;

[0047] The editing module is used to edit the configuration files of the smart substation, complete the device naming definition, and delete and add virtual circuits;

[0048] The rule creation module is used to map the secondary equipment entity attribute labels, the relationship topology between secondary equipment and the virtual terminal information to the verification rule model, and generate the virtual circuit verification rules between the specific attribute devices.

[0049] Compared with the prior art, the present invention has the following beneficial effects:

First, the main factors causing differences in virtual circuits of secondary equipment in smart substations are fully considered, a virtual circuit verification rule model for smart substations is created, and secondary equipment attribute labels are defined to ensure the uniqueness of verification rules and the accuracy of calling. Then, by parsing a sample of a configuration file of a smart substation, the entity attribute labels and relationship topology of secondary equipment are obtained, and further intelligently matched with a verification rule database layer by layer to avoid repeated learning. Finally, the entity attribute labels of equipment in the sample, the relationship topology, and the virtual circuit connections between equipment are automatically recorded to generate virtual circuit verification rules between equipment with specific attributes. The present invention utilizes machine learning technology to replace manual automatic generation of virtual circuit verification rules through sample case learning, thereby greatly improving the construction efficiency and quality of the virtual circuit verification rule base for smart substations, thereby promoting the engineering application of the automatic verification technology for virtual circuits in smart substations.

[0051] The construction of the virtual circuit verification rule base of the smart substation is a complex but crucial process. It ensures that the logical connection of the secondary system in the substation is correct. Through steps 1-7, the verification rule model is created, samples are obtained, samples are parsed, samples are retrieved, and verification rules are generated according to the retrieval results. The entire construction process combines multiple technical means such as automated parsing, database retrieval, and expert verification to ensure the comprehensiveness and accuracy of the virtual circuit verification rule base of the smart substation. Through continuous iteration and improvement, the rule base can effectively support the operation and management of smart substations and improve the safety and reliability of substations.

The main connection mode attribute labels of the primary equipment connected to the secondary equipment can be defined and expanded according to the actual situation in the region.

[0079] Preferably, the process of extracting the secondary device entity attribute labels and the relationship topology between the secondary device entities in step 3 includes:

[0080] Step 3-1, parse the imported SCD file sample, and obtain the device name, description, model, manufacturer, and version attribute information list of all secondary equipment entities in the SCD file sample;

[0081] Step 3-2, according to the naming specification of intelligent electronic devices in smart substations, parse the names of physical devices of each secondary device respectively, and obtain the type of secondary device, the type of primary device to which the secondary device belongs, and the voltage level information of the primary device to which the secondary device belongs;

[0082] Step 3-3, parse the description of each secondary equipment entity, obtain the voltage level of the primary equipment to which the secondary equipment belongs, the type of primary equipment to which the secondary equipment belongs, the type of secondary equipment, and the secondary equipment set information, and proofread and supplement the secondary equipment entity attribute label extracted by parsing the secondary equipment entity device name;

[0083] Step 3-4, according to the information obtained by parsing the physical device name and device description of the secondary device, the primary device is matched and associated with the secondary device to which it belongs, the relationship topology between the primary and secondary devices is generated, and the secondary device is retrieved;

[0084] Step 3-5, parse the imported SCD file sample to obtain the physical virtual circuit connection network of the entire station secondary equipment;

[0085] Step 3-6, according to the generated relationship topology between the primary and secondary devices and the virtual circuit connection relationship between the secondary devices, determine the main wiring mode of the primary device to which the secondary device belongs;

[0086] Step 3-7, split the virtual circuit connection network of the entire station secondary equipment into multiple sub-networks in the format of "receiving end secondary equipment-sending end secondary equipment", and generate a relationship topology between secondary equipment entities.

[0087] According to the naming specification of intelligent electronic equipment in smart substations, parse the names of each secondary equipment entity to obtain the secondary equipment type, the type of primary equipment to which the secondary equipment belongs, and the voltage level attribute label of the primary equipment to which the secondary equipment belongs. Take a secondary equipment entity as an example, the device name is "PL2201A", and it is parsed according to the naming specification of intelligent electronic equipment in smart substations. "P" indicates that the secondary equipment type attribute label is a protection device, "L" indicates that the primary equipment type attribute label to which the secondary equipment belongs is a line, "2201" indicates the number of the primary equipment to which the secondary equipment belongs, and "22" indicates that the voltage level attribute label of the primary equipment to which the secondary equipment belongs is 220 kV, and "A" indicates that the secondary equipment is the first set of protection for the primary equipment to which it belongs;

[0088] Further parse the description of each secondary equipment entity device, obtain the voltage level of the primary equipment to which the secondary equipment belongs, the type of primary equipment to which the secondary equipment belongs, the type of secondary equipment, the set of secondary equipment, and other information, and proofread and supplement the secondary equipment entity attribute labels extracted by parsing the secondary equipment entity device name. Take a certain secondary equipment entity as an example, the device description is "220 kV City Light Line 1 First Protection Set PCS-931A-DG-GR", parse the device description, the attribute label of the voltage level of the primary equipment to which the secondary equipment belongs is 220 kV, the name of the primary equipment to which it belongs is City Light Line 1, the attribute label of the secondary equipment type is protection device, the set is the first set, the attribute label of the primary equipment type to which the secondary equipment belongs is line, and the secondary equipment model is PCS-931A-DG-GR;

[0089] According to the information obtained by parsing the physical device name and device description of the secondary device, the primary device is matched and associated with the secondary device to which it belongs, and a relationship topology between the primary and secondary devices is generated. Specifically, according to the number of the primary device to which the secondary device belongs obtained by parsing the physical device name of the secondary device, the secondary devices with the same number are associated with the same primary device, indicating that such secondary devices belong to the same primary device. Furthermore, according to the name of the primary device to which the secondary device belongs obtained by parsing the physical device description of the secondary device, the secondary devices with the same primary device name are associated with the same primary device, indicating that such secondary devices belong to the same primary device;

[0090] Parse the SCD file sample to obtain the physical virtual circuit connection network of the entire station's secondary equipment. Figure 3 The virtual circuit connection network diagram of the entire station secondary equipment of the present invention is shown. Figure 4 The topological diagram of the relationship between the secondary devices of the example of the present invention is shown. It should be noted that one of the connecting lines represents one or more virtual circuits;

[0091] According to the generated relationship topology between the primary and secondary devices and the virtual circuit connection relationship between the secondary devices, the main wiring mode of the primary device to which the secondary device belongs is determined. Specifically, the number of bus voltage transformers configured is the same as the number of bus segments, so the number of bus segments is determined by the number of bus voltage transformers configured, and then the main wiring mode of the bus is determined according to the number of segmented and bus-coupled primary devices. One bus is a single bus, two bus segments and one segment are single bus segments, two bus segments and one bus coupler are double buses, three bus segments, two bus couplers, and one segment are double bus single segments, and four bus segments, two bus couplers, and two segments are double bus double segments. For the two-thirds wiring mode, there are generally two bus segments, and the interval protection has a startup failure virtual circuit connection with at least two circuit breaker protections. Since the virtual circuit of the circuit breaker protection is also related to its access position, the circuit breakers are further distinguished into line-side circuit breakers, transformer-side circuit breakers, reactor-side circuit breakers, line-line series circuit breakers, line-transformer series circuit breakers, and line-reactor series circuit breakers according to the opening of the starting failure circuit of the circuit breaker protection. If the circuit breaker protection only receives the phase-splitting starting failure of the line protection, the circuit breaker is a line-side circuit breaker; if the circuit breaker protection only receives the three-phase starting failure of the transformer protection, the circuit breaker is a transformer-side circuit breaker; if the circuit breaker protection only receives the three-phase starting failure of the reactor protection, the circuit breaker is a reactor-side circuit breaker; if the circuit breaker protection receives the phase-splitting starting failure of two line protections, the circuit breaker is a line-to-line circuit breaker; if the circuit breaker protection receives the phase-splitting starting failure of one line protection and the three-phase starting failure of the transformer protection, the circuit breaker is a line-to-transformer circuit breaker; if the circuit breaker protection receives the phase-splitting starting failure of one line protection and the three-phase starting failure of the reactor protection, the circuit breaker is a line-to-reactor circuit breaker;

[0092] The virtual circuit connection network of the secondary equipment of the entire station is split into multiple sub-networks in the format of "receiving end secondary equipment-sending end secondary equipment" to generate an example of the present invention. Figure 4 In the example of the relationship topology between the secondary devices, the secondary device entity 1 is connected with the secondary device entity 5, the secondary device entity 7, and the secondary device entity 8 by virtual loops, and the secondary device entity 2 is connected with the secondary device entity 6, the secondary device entity 9, and the secondary device entity 10 by virtual loops.

[0093] Preferably, Figure 6 As shown, the retrieval of secondary devices in step 3-4 includes a first screening process and a second screening process;

[0094] The first screening process uses a Bloom filter to filter out completely incorrect device relationship topologies in the smart substation virtual circuit verification rule database; according to the generated secondary device entity relationship topology, the device set is G(d)={d1,d2}, and the information set of each device is D(i)=(i1,i2,…,i n ), the Bloom filter consists of a bit vector B = {B[1], B[2], ..., B[m]} and k hash functions hash(1), hash(2), ..., hash(k) with a mapping range of {1, 2, ..., m}. Each device calculates k hash functions to obtain k independent mapping positions, and sets the contents of these positions to 1 in the bit vector to store elements. The device search operation obtains k devices to be searched according to the hash function hash calculation. i The index value hash(d i ), check the value B[hash(d i )],if B[hash(d i )]=1, it indicates that the device belongs to the inter-device relationship topology, otherwise it does not belong to the inter-device relationship topology, and the inter-device relationship topology set T1=(G(1), G(2), …, G(i), …, G(n)) containing device d1 in the virtual circuit verification rule database is obtained. The Bloom filter is continued to be used for secondary screening in the inter-device relationship topology set T1=(G(1), G(2), …, G(i), …, G(n)) to obtain the inter-device relationship topology set T2=(G(1), G(2), …, G(i), …, G(m)) containing both device d1 and device d2, where m≤n;

[0095] The second screening process is based on the matching of the global clustering coefficient of the topology, and obtains the unique relationship topology between the secondary device entities from the device relationship topology set T2 = (G(1), G(2), ..., G(i), ..., G(m)) obtained in the first screening process. The global clustering coefficient of the relationship topology set G(i) (G(i)∈T) between devices is equal, where the global clustering coefficient C of the relationship topology is:

[0096]

[0097] Where n represents the number of devices in the relationship topology, n = 2; v i represents the i-th device; V represents the node set, that is, V = v1, v2, ..., v n );C vi represents the individual clustering coefficient of the ith device; T Vi Indicates that the device (v i The vector value of the virtual circuit between adjacent devices, that is, the difference between the number of receiving virtual circuits and the number of sending virtual circuits; K Vi Indicates that in the relationship topology with the device v i The sum of the number of virtual circuits that exist.

[0098] The database retrieval in step 4 is based on the secondary device entity attribute labels and the relationship topology between devices extracted in step 3. The receiving-end secondary device entity attribute labels are input into the receiving-end secondary device in the smart substation virtual circuit verification rule database to retrieve the corresponding secondary device. The retrieval process is divided into two parts: the first screening process uses the Bloom filter to filter out completely incorrect relationship topologies between devices in the smart substation virtual circuit verification rule database; the second screening process uses the eigenvalue matching algorithm to match the accurate relationship topology between devices.

[0099] In the first screening process, the device set in the secondary device entity relationship topology obtained in step 3-4 is G(d) = {d1, d2}, and the information set of each device is D(i) = (i1, i2, ..., i n ), the Bloom filter consists of a bit vector B = {B[1], B[2], ..., B[m]} and k hash functions hash(1), hash(2), ..., hash(k) with a mapping range of {1, 2, ..., m}. Each device in the device set uses k hash functions to obtain k independent mapping positions, and sets the contents of these positions to 1 in the bit vector to store elements. For device search operations, the k devices to be searched are obtained according to the hash function hash calculation. i The index value hash(d i ), and then check the value B[hash(d i)],if B[hash(d i )]=1, it indicates that the device belongs to the inter-device relationship topology, otherwise it does not belong to the inter-device relationship topology. When the Bloom filter works normally, the probability that B[i] is set to 1 is

[0100] The probability of misjudgment pos at this time is:

[0101]

[0102] when Therefore, under the premise of the lowest error rate, the best effect is obtained by calculating m and k:

[0103]

[0104] According to the above steps, use Bloom filter to filter the device d1 in the secondary device entity relationship topology, and obtain the device relationship topology set T1 = (G(1), G(2), ..., G(i), ..., G(n)) that contains device d1 in the virtual circuit verification rule database; continue to use Bloom filter to perform secondary screening in the device relationship topology set T1 = (G(1), G(2), ..., G(i), ..., G(n)) to obtain the device relationship topology set T2 = (G(1), G(2), ..., G(i), ..., G(m)) (m≤n) that contains both devices d1 and d2.

[0105] In the second screening process, based on the matching of the global clustering coefficient of the topology, the relationship topology set T2 = (G(1), G(2), ..., G(i), ..., G(m)) obtained in the first screening process is used to obtain the unique relationship topology between the secondary device entities. The global clustering coefficient of the relationship topology set G(i) (G(i)∈T) between devices is equal, where the global clustering coefficient C of the relationship topology is:

[0106]

[0107] In the formula, n represents the number of devices in the relationship topology, and in the present invention, n=2; v i represents the i-th device; V represents the node set, that is, V = (v1, v2, ..., v n );C vi represents the individual clustering coefficient of the ith device; T Vi Represents the device v in the relational topology i The vector value of the virtual circuit between adjacent devices, that is, the difference between the number of receiving virtual circuits and the number of sending virtual circuits; K Vi Indicates that in the relationship topology with the device v i The sum of the number of virtual circuits that exist.

[0108] If the global clustering coefficient of the relationship topology between devices in the relationship topology set T2 between devices is equal to the global clustering coefficient of the relationship topology of the secondary device entity, the returned result is "yes".

[0109] If the global clustering coefficient of the relationship topology between devices does not exist in the relationship topology set T2 between devices and is equal to the global clustering coefficient of the secondary device entity relationship topology, the returned result is "no".

[0110] Preferably, in step 4, according to the extracted secondary device entity attribute tags and the relationship topology between the devices, the receiving-end secondary device entity attribute tags are input into the receiving-end secondary device of the smart substation virtual circuit verification rule database, the corresponding secondary device is retrieved, and the sending-end secondary device entity attribute tags are input into the sending-end secondary device in the above search results, and then the search is performed. If both the receiving-end and sending-end secondary device entities are retrieved and exist, the search result output is yes; if one or both of the receiving-end and sending-end secondary device entities are retrieved and do not exist, the search result output is no;

[0111] In step 5, the search result response is that it indicates that the virtual circuit verification rule between the secondary device entities currently searched already exists, and no rule creation is performed;

[0112] In step 6, if the search result responds to "no", it is marked with a certain color or symbol, indicating that the virtual circuit verification rule between the secondary equipment entities currently searched does not exist. The expert manually verifies the virtual circuit between the current secondary equipment entities. If the current virtual circuit is incorrect, the expert improves it to ensure that the virtual circuit is connected correctly.

[0113] Specifically, Figure 4 Taking the "Secondary Equipment Entity 1 - Secondary Equipment Entity 5" relationship topology shown in the figure as an example, the retrieval steps are as follows:

[0114] Obtain the attribute tag of the receiving-end secondary device entity 1, and search the attribute tag of the secondary device entity 1 in the receiving-end secondary device of the smart substation virtual circuit verification rule database. If the corresponding device can be matched, it means that the secondary device entity 1 already exists in the verification rule database, otherwise, it does not exist;

[0115] Obtain the attribute tag of the secondary device entity 5 of the sending end, and search the attribute tag of the secondary device entity 5 in the secondary devices of the sending end in the above search results. If the corresponding device can be matched, it means that the virtual loop verification rule of "secondary device entity 1-secondary device entity 5" already exists in the verification rule database, otherwise, it does not exist;

[0116] If both secondary device entity 1 and secondary device entity 5 are retrieved and exist, the search result output is yes; if one or both of secondary device entity 1 and secondary device entity 5 are retrieved and do not exist, the search result output is no. Specifically, the search result responds to yes, that is, the virtual loop verification rule of the currently retrieved secondary device entity and the relationship "secondary device entity 1-secondary device entity 5" already exists, and no rule creation is performed. Specifically, the search result responds to no, that is, the virtual loop verification rule of the currently retrieved secondary device entity and the relationship "secondary device entity 1-secondary device entity 5" does not exist, and a certain color and / or symbol is used to distinguish it from the secondary device entity attribute label and the relationship topology between secondary devices in the search result response yes, so as to facilitate experts to conduct targeted reviews;

[0117] Verification rule review experts manually verify and confirm the virtual circuits between the current secondary equipment entities. The verification and confirmation content includes whether the virtual terminal description and virtual terminal index, the connection relationship between virtual terminals is correct, whether there are any virtual terminal selection errors, virtual circuit omissions, or multiple connections. If the current virtual circuit is incorrect, the experts will improve it to ensure that the virtual circuit connection is correct.

[0118] Preferably, in step 3-4, according to the number of the primary device to which the secondary device belongs obtained by parsing the physical device name of the secondary device, the secondary devices with the same number are associated with the same primary device, indicating that such secondary devices belong to the same primary device, and according to the name of the primary device to which the secondary device belongs obtained by parsing the physical device description of the secondary device, the secondary devices with the same primary device name are associated with the same primary device, indicating that such secondary devices belong to the same primary device.

[0119] Specifically, according to the number of the primary device to which the secondary device belongs obtained by parsing the physical device name of the secondary device, the secondary devices with the same number are associated with the same primary device, indicating that such secondary devices belong to the same primary device. According to the name of the primary device to which the secondary device belongs obtained by parsing the physical device description of the secondary device, the secondary devices with the same primary device name are associated with the same primary device, indicating that such secondary devices belong to the same primary device.

[0120] Preferably, in the steps 3-6, the number of bus segments is determined by the number of bus voltage transformers configured, and then the main connection mode of the bus is determined according to the number of segmentation and bus-connecting primary devices.

[0121] Specifically, the number of bus voltage transformer configurations is the same as the number of bus sections, so the number of bus sections is determined by the number of bus voltage transformer configurations, and then the main bus connection method is determined according to the number of segmentation and bus coupling primary equipment. One bus section is a single bus, two bus sections and one segment are single bus segmentation, two bus sections and one bus coupling are double bus, three bus sections, two bus couplings, and one segment are double bus single segmentation, and four bus sections, two bus couplings, and two segments are double bus double segmentation. For the two-thirds wiring method, there are generally two bus sections, and the interval protection is connected to at least two circuit breaker protections by a startup failure virtual circuit. Since the virtual circuit of the circuit breaker protection is also related to its access position, the circuit breakers are further distinguished into line-side circuit breakers, transformer-side circuit breakers, reactor-side circuit breakers, line-line series circuit breakers, line-transformer series circuit breakers, and line-reactor series circuit breakers according to the startup failure circuit of the circuit breaker protection. If the circuit breaker protection only receives the phase-splitting starting failure of the line protection, the circuit breaker is a line-side circuit breaker; if the circuit breaker protection only receives the three-phase starting failure of the transformer protection, the circuit breaker is a transformer-side circuit breaker; if the circuit breaker protection only receives the three-phase starting failure of the reactor protection, the circuit breaker is a reactor-side circuit breaker; if the circuit breaker protection receives the phase-splitting starting failure of two line protections, the circuit breaker is a line-line series circuit breaker; if the circuit breaker protection receives the phase-splitting starting failure of one line protection and the three-phase starting failure of the transformer protection, the circuit breaker is a line-transformer series circuit breaker; if the circuit breaker protection receives the phase-splitting starting failure of one line protection and the three-phase starting failure of the reactor protection, the circuit breaker is a line-reactor series circuit breaker.
