Description

Technical Field

[0001] This invention relates to the field of Internet technology, and in particular to a method, apparatus, device, and medium for verifying relay protection settings. Background Technology

[0002] Relay protection devices are crucial equipment in power systems used to monitor and protect the safety of power facilities. They can quickly disconnect power in the event of a fault, ensuring the stable operation of the power system. Protection settings are a series of pre-set logic parameters within the relay protection device. These settings are used to determine whether a fault or anomaly has occurred in the power system and to decide whether to activate the relay protection device's protective actions, such as tripping or issuing an alarm. The purpose of protection setting verification is to ensure that the actual settings of the relay protection device are consistent with the current power system's required setting scheme.

[0003] With the optimization of relay protection devices, the protection functions of individual relay protection devices have become more diverse. For example, a single relay protection device can have overcurrent protection, undervoltage protection, differential protection, and distance protection. Each protection function has corresponding protection setting parameters that need to be set and verified. Therefore, the number of protection settings that need to be verified is large. However, manual verification is inefficient, consuming a lot of time and posing a risk of errors. Furthermore, because relay protection devices produced by different manufacturers or located in different power plant areas have different names for setting items, the matching degree of automatic protection setting verification systems is low, requiring multiple manual verifications and resulting in low automation. Therefore, existing protection setting verification suffers from low verification efficiency and low automation. Summary of the Invention

[0018] According to another aspect of the present invention, embodiments of the present invention also provide a relay protection setting verification device, the relay protection setting verification device comprising:

[0019] At least one processor; and

[0020] A memory that is communicatively connected to at least one processor; wherein,

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0032] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0033] In the technical solutions of the embodiments of the present invention, the acquisition, storage and application of the fixed value standard information and fixed value knowledge graph, etc., all comply with the provisions of relevant laws and regulations and do not violate public order and good morals.

[0034] Figure 1 This is a flowchart illustrating a relay protection setting verification method provided in an embodiment of the present invention. This embodiment is applicable to the verification of relay protection settings. The method can be executed by a relay protection setting verification device, which can be implemented in hardware and / or software. This relay protection setting verification device can be configured in a server.

[0035] See Figure 1 The relay protection setting verification method shown includes:

[0036] S101. Obtain the fixed value standard information and fixed value knowledge graph sent by the server; the fixed value standard information includes at least one first fixed value item, at least one first fixed value group and application information of each first fixed value group, each first fixed value group includes the first attribute value of each first fixed value item; the first attribute values ​​of each first fixed value item in each first fixed value group are not all the same.

[0037] Among them, the setting standard information is the setting information of protection equipment formulated according to the power system operation requirements. The setting standard information is used to verify the correctness of the information set by the protection equipment.

[0038] Setting items are attribute items set to protect protective equipment. For example, a setting item could be: zero-sequence current, stage I current. The first setting item is a setting item in the setting standard information.

[0039] Attribute values ​​are the values ​​of setpoints. For example, the attribute value of the zero-sequence current (section I) setpoint is 0.80, meaning the zero-sequence current (section I) cannot exceed 0.80A. A setpoint can have multiple attribute values. Different setpoints can use different attribute values ​​to form different setpoint groups. A setpoint group is a set of attribute values ​​configured for all setpoints by a protection device under a specific operating scenario. A protection device can have multiple setpoint groups. For example, a protection device might run setpoint group 1 in a dual-busbar operation scenario and setpoint group 2 in a single-busbar operation scenario. Setpoint groups 1 and 2 include all setpoints, but the attribute values ​​of the same setpoints in setpoint groups 1 and 2 are not all the same. "Not all the same" means that at least one setpoint has a different attribute value in setpoint groups 1 and 2.

[0040] The first setpoint group is the setpoint group in the setpoint standard information. The first attribute value is the attribute value of the first setpoint item in the first setpoint group. The first attribute values ​​of the first setpoint items in different first setpoint groups are not all the same, that is, at least one first setpoint item has a different first attribute value in different first setpoint groups. For example, both first setpoint group 1 and first setpoint group 2 have a first setpoint item: zero-sequence current segment I current setpoint item. The attribute value of the zero-sequence current segment I current setpoint item in first setpoint group 1 is 0.80, and the attribute value of the zero-sequence current segment I current setpoint item in first setpoint group 2 is 0.85. Therefore, first setpoint group 1 and first setpoint group 2 meet the requirement that the first attribute values ​​of the first setpoint items in each first setpoint group are not all the same.

[0041] The application information of the first setpoint group is the information of the operating scenarios that each first setpoint group is adapted to. For example, the first setpoint group 1 is adapted to the operating scenario of double busbar operation, and the first setpoint group 2 is adapted to the operating scenario of single busbar operation.

[0042] Knowledge graphs are semantic networks constructed with entities as nodes and the relationships between entities as edges. They are used to structurally describe entities and the relationships between them. Fixed-value knowledge graphs are knowledge graphs with fixed-value related entities as nodes and the relationships between fixed-value related entities as edges.

[0043] Optionally, the fixed value standard information and fixed value knowledge graph can be obtained from the server, and the handheld terminal can send a request to the operation and maintenance management server, which in turn sends the fixed value standard information and fixed value knowledge graph to the handheld terminal.

[0044] S102. Obtain the target setting information and current operation information of the protection device in the connected state; the target setting information includes at least one second setting item and at least one second setting group, the second setting group includes the second attribute value of each second setting item.

[0045] Among them, the current operating information reflects the current operating status of the protection equipment in the current power system; the current operating information can refer to information collected in real time; the target setpoint information is the setpoint information that needs to be verified in the protection equipment; the target setpoint information can refer to the setpoint information obtained in real time from the protection equipment currently in a connected state; the second setpoint item is the setpoint item of the target setpoint information; the second setpoint group is the setpoint group in the target setpoint information; and the second attribute value is the attribute value of the second setpoint item in the target setpoint information. The first attribute value of the first setpoint item is a parameter preset according to the power system operating requirements, and the second attribute value of the second setpoint item is a parameter obtained in real time from the protection equipment currently in a connected state.

[0046] Optionally, before obtaining the target setting information and current operating information of the protection device in the connected state, the protection device in the connected state is authenticated from three dimensions: model, manufacturing number, and location, to determine that the protection device in the connected state is the protection device to be verified.

[0047] S103. Based on the fixed value knowledge graph and each of the first fixed value items, verify each of the second fixed value items to obtain the fixed value item verification result.

[0048] Based on the relationships between the fixed-value related entities in the fixed-value knowledge graph and the first fixed-value item, the second fixed-value item is matched with the first fixed-value item. If the second fixed-value item can be matched with the first fixed-value item, the fixed-value item verification result is passed; if the second fixed-value item does not match any of the first fixed-value items, the fixed-value item verification result is failed.

[0049] S104. Based on the verification results of the fixed value items and each of the first fixed value groups, verify each of the second fixed value groups to obtain the verification results of the fixed value groups.

[0050] If the verification result of the fixed value item is passed, the correspondence between the first and second fixed value items can be obtained. The second attribute value of the corresponding second fixed value item is verified based on the first attribute value of each first fixed value item. For each second fixed value item, if the second attribute value of the second fixed value item is consistent with the first attribute value of its corresponding first fixed value item, then the attribute value verification result of the second fixed value item is passed.

[0051] If the attribute value verification results of each second fixed value item in a second fixed value group are all passed, then the verification of the fixed value group is passed; if there is a second fixed value item whose attribute value verification result is not passed, then the verification of the fixed value group is not passed.

[0052] If all the verifications of the second setpoint groups in the protection device pass, then the verification result of the setpoint groups is determined to be passed.

[0053] In an optional embodiment, the step of verifying each second setpoint group based on the verification result of the setpoint item and each first setpoint group to obtain the setpoint group verification result includes:

[0054] Based on the verification results of the fixed value items, determine the second fixed value item corresponding to each first fixed value item; for each first fixed value group, check whether there is a corresponding second fixed value group for the first fixed value group, and the first attribute value of each first fixed value item in the first fixed value group is consistent with the second attribute value of the corresponding second fixed value item in the corresponding second fixed value group; if each first fixed value group corresponds one-to-one with each second fixed value group, determine that the fixed value group verification result is verified as passed; if each first fixed value group does not correspond one-to-one with each second fixed value group, determine that the fixed value group verification result is verified as failed.

[0055] Based on the verification results of the fixed value items, the second fixed value item corresponding to the first fixed value item can be determined. Using each first fixed value item in the first fixed value group as a benchmark, the corresponding second fixed value item in the second fixed value group is verified. The verification content includes verifying the second attribute value of the corresponding second fixed value item in the second fixed value group using the first attribute value of each first fixed value item in the first fixed value group, and obtaining the attribute value verification result.

[0056] For example: the first setting group contains the first setting item, the overcurrent protection setting, whose first attribute value is 0.80; the second setting group contains the second setting item, the overload current setting, whose second attribute value is 0.80. Based on the setting item verification results, the overcurrent protection setting in the first setting item corresponds to the overload current setting in the second setting item. Therefore, the first attribute value of the overcurrent protection setting is used to verify the second attribute value of the overload current setting. Since the attribute values ​​are consistent (both are 0.80), the attribute value verification result is passed.

[0057] If each first fixed value item in the first fixed value group has a corresponding second fixed value item, and the first attribute value of the first fixed value item is consistent with the second attribute value of the corresponding second fixed value item, then it is determined that the first fixed value group has a corresponding second fixed value group.

[0058] For example, the first setting group A contains three first setting items: overcurrent protection setting, overvoltage protection setting, and undervoltage protection setting. The first attribute values ​​of the first setting items are 0.80 for overcurrent protection, 250 for overvoltage protection, and 180 for undervoltage protection, respectively. The second setting group a contains three second setting items: overload current setting, overvoltage protection setting, and undervoltage protection setting. The second attribute values ​​of the second setting items are 0.80 for overload current, 250 for overvoltage protection, and 180 for undervoltage protection, respectively. According to the setting item verification results, the overcurrent protection setting, overvoltage protection setting, and undervoltage protection setting in the first setting group A correspond to the overload current setting, overvoltage protection setting, and undervoltage protection setting in the second setting group a, respectively, and the corresponding attribute values ​​of the corresponding setting items are also consistent. Therefore, it is determined that the first setting group A has a corresponding second setting group a.

[0059] If each first set of fixed values ​​has one and only one corresponding second set of fixed values, and each second set of fixed values ​​corresponds to one first set of fixed values, then each first set of fixed values ​​is said to have a one-to-one correspondence with each second set of fixed values. If each first set of fixed values ​​corresponds to each second set of fixed values, the verification result of the fixed value group is "passed"; if each first set of fixed values ​​cannot correspond to each second set of fixed values, the verification result of the fixed value group is "failed".

[0060] For example: the standard setting information contains three first setting value groups, namely first setting value group A, first setting value group B, and first setting value group C; the target setting value information contains three second setting value groups, namely second setting value group a, second setting value group b, and second setting value group c. If first setting value group A corresponds to second setting value group a, first setting value group B corresponds to second setting value group b, and first setting value group C corresponds to second setting value group c, then the setting value group verification result is "passed". If first setting value group A cannot correspond to any second setting value group, or second setting value group a cannot correspond to any first setting value group, then the setting value group verification result is "failed".

[0061] It is evident that by limiting the fixed value group verification method to determining the second fixed value item corresponding to each first fixed value item based on the verification result of the fixed value item; for each first fixed value group, checking whether there is a corresponding second fixed value group; and then determining the fixed value group verification result based on the one-to-one correspondence between each first fixed value group and each second fixed value group, the verification logic is rigorous, ensuring the consistency between the second fixed value group and the first fixed value group, and improving the accuracy of the verification.

[0062] In an optional embodiment, the first attribute value of each first attribute item in the first set value group is consistent with the second attribute value of the corresponding second set value item in the corresponding second set value group, including: the numerical deviation between the first attribute value and the second attribute value of the numeric type is less than or equal to a preset error threshold, or the first attribute value and the second attribute value of the character type are consistent.

[0063] Distinguishing between numeric and character type attribute values ​​allows for flexible adaptation to different protection devices based on their display standards.

[0064] If the attribute value is a numeric type, the numerical deviation between the first attribute value and the second attribute value must be less than or equal to a preset error threshold. Optionally, the preset error threshold can be set according to the display accuracy of the protection device. For example, if the display accuracy of the protection device is 0.01, the preset error threshold can be 0.01. When the first attribute value is 0.80 and the second attribute value is 0.81, it is determined that the numerical deviation does not exceed the preset error threshold, and the detection results of the first attribute value and the second attribute value are consistent.

[0065] If the attribute value is a character type, the first attribute value and the second attribute value must be exactly the same. For example, if the first attribute value is "input" and the second attribute value is "operation", then the detection results of the first attribute value and the second attribute value are inconsistent.

[0066] As can be seen, by setting consistency detection rules based on the type of attribute value, for numeric attribute values, considering factors such as protecting the display accuracy of the device, the rules limit the allowable numerical deviation of numeric attribute values ​​to be less than or equal to a preset error threshold. This can avoid inconsistencies in multiple detection results caused by device display issues, making the verification results of numeric attribute values ​​more stable. For character attribute values, considering that subtle differences in expression may cause ambiguity, the rules limit the character attribute values ​​to be completely consistent, making the verification results of character attribute values ​​more accurate.

[0067] S105. Based on the current operating information, determine the current setting group of the protection device in the second setting group.

[0068] The current operating information reflects the operating status of the protection equipment in the current power system. Based on the current operating information, the operating scenario of the current power system and the current set value group of the protection equipment can be obtained.

[0069] S106. Based on the application information of each of the first set value groups, the current set value group is verified to obtain the running verification result.

[0070] Verifying the current setpoint group can refer to verifying whether the current setpoint group of the protection device meets the requirements. For example, if the application information of the first setpoint group requires the operation of the first setpoint group 1 in a dual-bus operation scenario, and if the current power system operation scenario is a dual-bus operation scenario, and the current setpoint group is the second setpoint group 1, and the second setpoint group 1 corresponds to the first setpoint group 1, then the verification passes.

[0071] In an optional embodiment, after verifying the current setpoint group based on the application information of each of the first setpoint groups and obtaining the running verification result, the method further includes:

[0072] If any of the verification results of the setpoint item, the setpoint group, and the operation verification result fail, the user is prompted to modify the target setpoint information of the protection device to obtain the modified target setpoint information.

[0073] Based on the modified target setpoint information, each of the second setpoint items is verified to obtain the modified setpoint item verification result, the setpoint group verification result, and the operation verification result.

[0074] When there are any failed verifications in the setpoint item verification results, setpoint group verification results, and operation verification results, the failed items can be marked, prompting the user to modify the failed items, save the modified target setpoint information, and perform verification again to obtain the modified setpoint item verification results, setpoint group verification results, and operation verification results.

[0075] Optionally, when any of the verification results of the setpoint item, the setpoint group, and the operation verification result fail, the handheld terminal highlights the failed item and indicates the type of failure, such as: setpoint item verification failed, setpoint group verification failed, or operation verification failed. Furthermore, for numerical attribute values, the deviation rate can be automatically calculated. For example, if the first attribute value is 0.80 and the second attribute value is 0.85, the deviation rate is calculated by subtracting the second attribute value from the first attribute value to obtain the error amount. The absolute value of the error amount is then divided by the first attribute value and multiplied by 100%, resulting in an automatically calculated deviation rate of 6.25%.

[0076] Optionally, to ensure successful storage of the modified target value information, the data from each verification can be generated into a hash sequence in the format of "second value item + second attribute value + unit of measurement." This hash sequence is a sequence of related data generated using a hash function. For example, "second value item 1 + second attribute value 1 + unit of measurement" generates hash value 1, "second value item 2 + second attribute value 2 + unit of measurement + hash value 1" generates hash value 2, and so on. After iterative calculations for the target number of times, a final hash value is obtained. The target number of times is the same as the number of second value items. The final hash value, the unique identifier for this protection value verification, and the time of this protection value verification are packaged, encrypted, and sent to the blockchain node. After the node verifies the permissions, the hash value is written to the private blockchain storage. After verifying the second value item for the modified target value information, the previous final hash value can be retrieved for comparison to ensure that the modification of the target value information takes effect.

[0077] As can be seen, by prompting users to modify the target setting information that fails the verification, and then re-verifying the modified target setting information, a closed loop of protection setting verification is achieved, ensuring that the protection setting in the final protection device is accurate.

[0078] The technical solution of this invention obtains setting standard information and setting knowledge graph sent by a server. The setting standard information includes a first setting item, a first setting group, and application information of each first setting group. Each first setting group also includes a first attribute value of each first setting item. The invention then obtains target setting information and current operating information of a protection device in a connected state. The target setting information includes a second setting item and a second setting group. Each second setting group includes a second attribute value of each second setting item. The invention verifies each second setting item based on the setting knowledge graph and each first setting item to obtain a setting item verification result. This result is then combined with each first setting group to verify each second setting group, resulting in a setting group verification result. Finally, based on the current operating information, the current setting group of the protection device is determined from the second setting group. The current setting group is then verified with reference to the application information of each first setting group to obtain an operating verification result. This invention replaces the traditional process of manually querying standards and comparing items one by one with an automated information acquisition and verification process, significantly improving the efficiency of protection setting verification, solving the problem of low efficiency in existing protection setting verification, and reducing manual operation costs and the probability of human error. Based on the association relationship of setting-related entities in the setting knowledge graph, the second setting item is matched with the first setting item, solving the problem that the names of setting items with the same function may differ due to relay protection devices produced by different manufacturers or relay protection devices located in different power plant areas, requiring multiple manual verifications of setting items, thus improving the automation level of relay protection setting verification.

[0079] Figure 2 This is a flowchart of a relay protection setting verification method provided by an embodiment of the present invention. Based on the above embodiments, this embodiment verifies each second setting item according to the setting knowledge graph and each first setting item to obtain a setting item verification result. Specifically, the method involves: querying the entity information corresponding to the protection device in the setting knowledge graph; determining the equivalent entity corresponding to each second setting item based on the entity information corresponding to the protection device; performing consistency checks on each first setting item with each second setting item and its corresponding equivalent entity; determining that the setting item verification result is passed when it is determined that each first setting item corresponds one-to-one with each second setting item; determining that the setting item verification result is failed when there is no correspondence between a first setting item and each second setting item or its corresponding equivalent entity; and determining that the setting item verification result is failed when there is no correspondence between a second setting item and its corresponding equivalent entity and each first setting item.

[0080] It should be noted that for parts not described in detail in the embodiments of the present invention, please refer to the descriptions in other embodiments.

[0081] See Figure 2 The relay protection setting verification method shown includes:

[0082] S201. Obtain the fixed value standard information and fixed value knowledge graph sent by the server; the fixed value standard information includes at least one first fixed value item, at least one first fixed value group and application information of each first fixed value group, each first fixed value group includes the first attribute value of each first fixed value item; the first attribute values ​​of each first fixed value item in each first fixed value group are not all the same.

[0083] S202. Obtain the target setting information and current operation information of the protection device in the connected state; the target setting information includes at least one second setting item and at least one second setting group, the second setting group includes the second attribute value of each second setting item.

[0084] S203. Query the entity information corresponding to the protection device in the fixed value knowledge graph.

[0085] Among them, entity information refers to the information of fixed-value related entities in the fixed-value knowledge graph.

[0086] In the setting knowledge graph, the setting group information of the protection device to be verified is obtained by obtaining the model of the protection device, and the setting items and their relationships under each setting group are queried.

[0087] In an optional embodiment, the fixed value knowledge graph includes: nodes of protection devices and nodes of fixed value entities; the entity information corresponding to the protection device in the fixed value knowledge graph includes: information associated with the nodes of the fixed value entities connected to the nodes of the protection devices.

[0088] In this context, a node for a protection device can refer to a node generated based on that protection device. Nodes can be generated according to the model of the protection device. Nodes generated based on the device model are used to represent and store the models of protection devices from different manufacturers and series.

[0089] A setting entity can refer to information related to the setting items of a protection device. A setting entity node is a node that represents and stores information related to the setting entity. Setting entity nodes can include setting group entity nodes and setting item entity nodes. Setting item entity nodes can include standard setting item nodes and extended setting item nodes. Standard setting item nodes represent and store standard expressions related to settings that are uniformly regulated within the power industry. Extended setting item nodes represent and store non-standard expressions related to settings from different manufacturers or in actual field applications.

[0090] In the setting value knowledge graph, the nodes of the protection device and the setting value group nodes are associated based on the attribute information of the protection device. This is used to establish the attribution association between a specific device model and the setting value groups that the device can configure, indicating the range of setting value groups supported by a certain device model.

[0091] The setting group node and the standard setting item node are associated according to the protection functions required by the power system, which is used to reflect the composition of the setting group and clarify the setting items included in each setting group.

[0092] Standard and extended value item nodes are associated based on the similarity of the value items. This is used to map non-standard expressions related to the value to standard expressions related to the value, establishing a correspondence between non-standard and standard expressions. Optionally, the similarity between the first and second value items is calculated based on the edit distance algorithm as the target similarity. A standard similarity is set, and the target similarity is compared with the standard similarity. If the target similarity is higher than the standard similarity, the first and second value items are automatically associated. If the target similarity is not higher than the standard similarity, the user is prompted for confirmation, and manual association is possible. For example, if the standard similarity is set to 90%, and there is a first value item "zero-sequence current segment I" and a second value item "zero-current segment I", the similarity between "zero-sequence current segment I" and "zero-current segment I" calculated by the edit distance algorithm is 92%, which is higher than the standard similarity of 90%, so "zero-sequence current segment I" and "zero-current segment I" are automatically associated.

[0093] The entity information corresponding to the protection device in the fixed value knowledge graph includes the information on the relationships between the above nodes.

[0094] As can be seen, by specifying the nodes of the setting value knowledge graph as nodes of protection devices and nodes of setting value entities, and by specifying the entity information corresponding to the protection devices in the setting value knowledge graph as the information associated with the nodes of the setting value entities connected to the nodes of the protection devices, a method for constructing a setting value knowledge graph is provided. This method standardizes and organizes the information of protection devices, making it easier to efficiently query the association relationships of setting value items.

[0095] S204. Based on the entity information corresponding to the protection device, determine the equivalent entity corresponding to each of the second setting items.

[0096] Here, equivalent entities can refer to entities with similar semantics. In reality, the names of the defined value items may differ between manufacturers in different scenarios, but they refer to the same value item. By querying the entity information corresponding to the protection device and finding the value item similar to the second value item, the equivalent entity corresponding to the second value item can be obtained.

[0097] Optionally, in the extended value item node, query the non-standard expression value item with the same expression as the second value item. Based on the association information between the standard value item node and the extended value item node, obtain the standard expression value item in the standard value item node associated with the non-standard expression value item, and determine the standard expression value item as the equivalent entity corresponding to the second value item.

[0098] S205. Perform consistency checks on each of the first fixed value items with each of the second fixed value items and the corresponding equivalent entities.

[0099] Each first fixed value item is checked for consistency with each second fixed value item and the corresponding equivalent entity.

[0100] For example: the first setting is an overcurrent protection setting, the second setting is an overload current setting, and the equivalent entity corresponding to the second setting is an overcurrent protection setting. The consistency of the first setting's overcurrent protection setting and the second setting's overload current setting is checked. Similarly, the consistency of the first setting's overcurrent protection setting and the equivalent entity's overcurrent protection setting is also checked. This process is repeated, with each first setting being checked for consistency with each second setting and its corresponding equivalent entity.

[0101] Optionally, consistency detection can use the edit distance algorithm to calculate the similarity between the first fixed value item and the second fixed value item and the corresponding equivalent entity. If any of the obtained similarities is higher than the set standard, it is determined to be consistent.

[0102] S206. When it is determined that each of the first fixed value items corresponds one-to-one with each of the second fixed value items, the verification result of the fixed value item is determined to be that the verification is passed.

[0103] When there is a first fixed value item that does not correspond to any of the second fixed value items and their corresponding equivalent entities, the verification result of the fixed value item is determined to be a verification failure.

[0104] When there is a second fixed value item and its corresponding equivalent entity that do not correspond to any of the first fixed value items, the verification result of the fixed value item is determined to be a verification failure.

[0105] Perform a consistency check on the first fixed value item, the second fixed value item, and their equivalent entities. If the check result is consistent, it means that the first fixed value item and the second fixed value item correspond.

[0106] If each of the first and second fixed values ​​corresponds one-to-one, then the verification result of the fixed value is that the verification is passed.

[0107] If a first value item cannot correspond to any second value item, and the first value item cannot correspond to an equivalent entity of the second value item, then the value item verification result is that the verification fails.

[0108] If there exists a second value item and its equivalent entity that cannot correspond to any of the first value items, then the value item verification result is that the verification fails.

[0109] In an optional embodiment, determining that each of the first setpoints corresponds one-to-one with each of the second setpoints includes:

[0110] For each of the first value items, when the first value item and the second value item are semantically similar or the equivalent entity corresponding to the first value item and the second value item is semantically similar, it is determined that the first value item and the second value item correspond.

[0111] When each of the first fixed value items has one and only one corresponding second fixed value item, and each of the second fixed value items has one and only one corresponding first fixed value item, it is determined that each of the first fixed value items and each of the second fixed value items are in one-to-one correspondence.

[0112] Based on the first fixed value term, if the second fixed value term or its equivalent entity is semantically similar to the first fixed value term, then the first fixed value term is determined to correspond to the second fixed value term.

[0113] For example: the first setting is an overcurrent protection setting, the second setting is an overload current setting, and the equivalent entity corresponding to the second setting is an overcurrent protection setting. If the equivalent entity corresponding to the second setting is semantically similar to the first setting, then the overcurrent protection setting of the first setting and the overload current setting of the second setting are determined to correspond.

[0114] If each first fixed value has one and only one corresponding second fixed value, and each second fixed value corresponds to one first fixed value, then it is determined that each first fixed value corresponds to each second fixed value.

[0115] For example: the standard setting information includes a first setting item A, a first setting item B, and a first setting item C; the target setting information includes a second setting item a, a second setting item b, and a second setting item c. If first setting item A corresponds to second setting item a, first setting item B corresponds to second setting item b, and first setting item C corresponds to second setting item c, then each first setting item corresponds one-to-one with each second setting item. If first setting item A cannot correspond to any second setting item, or second setting item a cannot correspond to any first setting item, then each first setting item does not correspond one-to-one with each second setting item.

[0116] As can be seen, by determining a one-to-one correspondence between each of the first and second value items, specifically if the second value item or its corresponding equivalent entity is semantically similar to the first value item, then the first and second value items are determined to correspond; if each first value item has one and only one corresponding second value item, and each second value item corresponds to one first value item, then each first and second value item is determined to correspond one-to-one. This provides a method for determining a one-to-one correspondence between the first and second value items, making the consistency detection of value items more accurate.

[0117] S207. Based on the verification results of the fixed value items and each of the first fixed value groups, verify each of the second fixed value groups to obtain the verification results of the fixed value groups.

[0118] S208. Based on the current operating information, determine the current setting group of the protection device in the second setting group.

[0119] S209. Based on the application information of each of the first setpoint groups, the current setpoint group is verified to obtain the running verification result.

[0120] The technical solution of this invention verifies each second fixed value item based on a fixed value knowledge graph and each first fixed value item to obtain the fixed value item verification result. Specifically, it first queries the entity information corresponding to the protection device in the fixed value knowledge graph, then determines the equivalent entity corresponding to each second fixed value item based on the entity information, and then performs consistency checks on each first fixed value item with each second fixed value item and its corresponding equivalent entity. If all first fixed value items can be matched one-to-one with each second fixed value item, the verification result is determined to be passed. If there are first fixed value items that cannot be matched with each second fixed value item and its corresponding equivalent entity, or if there are second fixed value items and their corresponding equivalent entities that cannot be matched with each first fixed value item, the verification result is determined to be failed. By using the entity information in the fixed value knowledge graph to set verification rules, the fixed value item verification is completed, ensuring that there are no errors or omissions in the correspondence between the first and second fixed value items, thus improving the accuracy of the fixed value item verification.

[0121] Figure 3 This is a schematic diagram illustrating the structure for relay protection setting verification according to an embodiment of the present invention. This embodiment is applicable to relay protection setting verification, and the device can execute a relay protection setting verification method. The device can be implemented in hardware and / or software.

[0122] See Figure 3 The relay protection setting verification device shown includes:

[0123] The standard information acquisition module 301 is used to acquire the fixed value standard information and fixed value knowledge graph sent by the server; the fixed value standard information includes at least one first fixed value item, at least one first fixed value group and application information of each first fixed value group, each first fixed value group includes the first attribute value of each first fixed value item; the first attribute values ​​of each first fixed value item in each first fixed value group are not all the same.

[0124] The target information acquisition module 302 is used to acquire the target setting information and current operation information of the protection device in the connected state; the target setting information includes at least one second setting item and at least one second setting group, and the second setting group includes the second attribute value of each second setting item;

[0125] The fixed value item verification module 303 is used to verify each of the second fixed value items based on the fixed value knowledge graph and each of the first fixed value items, and obtain the fixed value item verification result.

[0126] The fixed value group verification module 304 is used to verify each of the second fixed value groups based on the verification results of the fixed value items and each of the first fixed value groups, so as to obtain the fixed value group verification results.

[0127] The operation result verification module 305 is used to determine the current setting group of the protection device in the second setting group according to the current operation information; and to verify the current setting group according to the application information of each first setting group to obtain the operation verification result.

[0128] The technical solution of this invention obtains setting standard information and setting knowledge graph sent by a server. The setting standard information includes a first setting item, a first setting group, and application information of each first setting group. Each first setting group also includes a first attribute value of each first setting item. The invention then obtains target setting information and current operating information of a protection device in a connected state. The target setting information includes a second setting item and a second setting group. Each second setting group includes a second attribute value of each second setting item. The invention verifies each second setting item based on the setting knowledge graph and each first setting item to obtain a setting item verification result. This result is then combined with each first setting group to verify each second setting group, resulting in a setting group verification result. Finally, based on the current operating information, the current setting group of the protection device is determined from the second setting group. The current setting group is then verified with reference to the application information of each first setting group to obtain an operating verification result. This invention replaces the traditional process of manually querying standards and comparing items one by one with an automated information acquisition and verification process, significantly improving the efficiency of protection setting verification, solving the problem of low efficiency in existing protection setting verification, and reducing manual operation costs and the probability of human error. Based on the association relationship of setting-related entities in the setting knowledge graph, the second setting item is matched with the first setting item, solving the problem that the names of setting items with the same function may differ due to relay protection devices produced by different manufacturers or relay protection devices located in different power plant areas, requiring multiple manual verifications of setting items, thus improving the automation level of relay protection setting verification.
