Description

Technical Field

[0001] The embodiments of the present invention relate to the operation and maintenance technology of relay protection equipment, and particularly to a method, device, computer equipment and storage medium for verifying the setting value of relay protection. Background Technology

[0002] With the steady development of my country's national economy and the year-by-year improvement of people's living standards, the demand for electricity in the whole society is also increasing. In order to protect the stable operation of the power system, relay protection equipment is widely used in all voltage levels of the power system. With the development of technology and the increasing demands of the people for power stability, the types of relay protection are becoming more diverse and the protection functions are becoming more detailed. This has resulted in a variety of types of relay protection equipment used in the power system. At the same time, due to the differences in the software settings of products from different manufacturers, the setting and adjustment of relay protection devices are complicated.

[0003] Currently, the relay protection setting system and the online verification and early warning system for relay protection settings are independent of the equipment operation and maintenance management system. When a power grid accident occurs or other reasons arise, it may be necessary to verify and assess whether certain setting principles need adjustment, depending on the system operation mode and the requirements for coordination between higher and lower levels. When the setting principles are assessed as needing adjustment, it is impossible to quickly obtain the number of operating devices on-site and the specific substations and bays involved. A manual survey of each substation, bay, and device is required, which is labor-intensive, time-consuming, and prone to errors and omissions.

[0004] While relay protection setting systems and online verification and early warning systems can assist in verifying and evaluating setting principles, they lack functions for maintaining a register of operating equipment and managing equipment settings. They cannot compile a list of operating equipment and their settings as needed. Although relay protection operation and maintenance management systems possess equipment register and setting management functions, these functions are relatively independent, lacking horizontal connections between modules. For example, while remote access is possible for statistical output of specific settings for a particular type, manual checks of each substation, bay, and device are still required, resulting in low efficiency and a high risk of errors. Summary of the Invention

[0005] This invention provides a method, device, computer equipment, and storage medium for verifying the settings of relay protection, so as to realize the equipment ledger information management and setting management function modules throughout the relay protection operation and maintenance management system, realize intelligent verification and automatic recall of settings, greatly improve work efficiency and reduce the scope of manual verification.

[0020] If the relay protection device is in a communication interruption state, and the set value is within the inspection cycle and is the set value before the communication interruption, then the set value is taken as the effective set value.

[0026] If the verification fails, the setting list and / or the relay protection device category shall be corrected based on the rated parameters of the relay protection device.

[0027] Optionally, after performing setting verification on the relay protection device based on the setting value sequence number and setting value name, the method further includes:

[0028] A message prompting the staff to review the verification results is generated.

[0045] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0046] Figure 1 This is a network architecture diagram of a relay protection operation and maintenance management system in the prior art. The relay protection operation and maintenance management system can obtain the equipment ledger of each access station through the protection and information substation / control substation and intelligent waveform recorder management unit. The equipment ledger information management supports the statistical management and retrieval of information such as equipment identification code, model, version, check code, program generation time, and equipment manufacturer of relay protection equipment. The system's setting value management function has functions such as setting value recall model modeling, setting value recall strategy, setting value comparison and verification, and setting value storage.

[0047] However, the system's equipment ledger and fixed value management functions are relatively independent, and there is a lack of horizontal connection between the functional modules. For example, when it is necessary to output the statistical values ​​of a certain type of fixed value, although it is possible to retrieve them remotely, it is still necessary to manually conduct a general survey of each plant, bay, and device, which is inefficient and prone to errors.

[0048] Example 1

[0049] Figure 2 This is a flowchart illustrating the relay protection setting verification method provided in Embodiment 1 of the present invention. This embodiment is applicable to intelligent setting verification in relay protection operation and maintenance management systems. The method can be executed by a relay protection setting verification device, which can be implemented using software and / or hardware. This device can be configured in a terminal device / server. The method specifically includes:

[0050] S110. Obtain the list of settings that need to be verified, and determine the category of relay protection equipment to which the settings in the list belong;

[0051] In power systems, relay protection equipment can be categorized into different types, including line protection, transformer protection, capacitor protection, and motor protection. These different types of relay protection equipment have different setpoints. Furthermore, due to varying demands within the power system, such as ambient temperature and circuit load, even the same relay protection equipment may have different setpoints. In a power system, relay protection equipment can automatically disconnect faulty equipment in the shortest time and within the smallest possible area, thereby mitigating or preventing the impact of faulty equipment on the power supply of neighboring areas. However, after prolonged operation, relay protection equipment ages and components fail frequently, requiring operators to conduct regular relay protection testing and maintenance.

[0052] The setpoint list is a list of setpoints stored in the relay protection operation and maintenance management system that needs to be verified. The setpoints are of different types and may belong to multiple relay protection devices of multiple types, or they may belong to a single relay protection device. The setpoints can be numbers or characters, such as 100V, 55Hz, or 0X3FFF.

[0053] Specifically, the setting management function of the relay protection operation and maintenance management system can be used to select the setting values ​​of the relay protection equipment to be checked from the setting values ​​stored in the system to generate a setting value list. The setting value list includes the device model, bay, and substation of the relay protection equipment to which the setting value belongs. Preferably, the category of relay protection equipment corresponding to the setting value can be determined based on the device model and bay in the setting value list.

[0054] S120. Determine the target relay protection standard model corresponding to the setting list from the candidate relay protection standard models belonging to the relay protection equipment category;

[0055] The standard model of the relay protection equipment can be a calculation model used to generate a power system that meets the requirements of the power system. This model can be built into the CPU of the relay protection equipment. The standard model of the relay protection equipment can also be an information model that defines the principle of setting value generation.

[0056] In power systems, different types of relay protection equipment have different relay protection standard models, such as line protection, transformer protection, capacitor protection, or motor protection. Even for the same type of relay protection equipment, power systems have different requirements, such as system parameters, protection function configurations, and coordination of operating values ​​and timing between different protection functions. Relay protection systems of the same type typically have one or more principle-based relay protection standard models used to generate one or more sets of protection settings suitable for the specific equipment. Under different standards, the value of the same setting item for the same type of relay protection equipment may differ.

[0057] After determining the category of relay protection equipment to which the values ​​in the value list belong, it is unclear what principle the values ​​in the value list are generated based on for that relay protection equipment. Therefore, they cannot be directly used to verify whether the value list meets the requirements of the power system.

[0058] Specifically, the setting management function of the relay protection operation and maintenance management system can be used to analyze setting items in multiple relay protection standard models belonging to the same type of product using fuzzy recognition and intelligent matching technologies. This allows for the determination of the relevant target relay protection standard models involved in the setting values ​​in the setting value list. For example, based on the relay protection standard models of similar products, multiple sets of setting values ​​under the corresponding models can be generated. Correlation analysis can then be performed with the setting values ​​in the setting value list that needs to be verified to determine the target relay protection standard model corresponding to the setting value list.

[0059] S130. Based on the target relay protection standard model, determine the setting value serial number and setting value name of the setting value in the setting value list;

[0060] S140. Determine the relay protection equipment that needs to be checked based on the aforementioned setting list;

[0061] Wherein, the setting value serial number can refer to the number assigned to the setting value among all the setting values ​​owned by the relay protection device, the setting value name can refer to the protection function name of the setting value in the relay protection device, and the relay protection device to be checked can be the relay protection device to which the setting value belongs in the setting value list.

[0062] Typically, a relay protection device has multiple setpoint protection functions. For example, a circuit breaker can have overload protection tripping current, short-circuit protection tripping current, rated ultimate short-circuit breaking capacity, and rated operating short-circuit breaking capacity. Under a relay protection standard model, there can be a setpoint dataset, for example, a setpoint dataset consisting of: No. 001, Name: Protection Enable / Disable Control Word, Setpoint 0X3FFF; No. 009, Name: Low Voltage Disconnection Stage I Setpoint, Setpoint 100V; No. 020, Name: High Frequency Cutting Machine First Round Setpoint, Setpoint 55Hz.

[0063] Therefore, after determining the target relay protection standard model, the setting value serial number and setting value name in the setting value list can be determined based on the target relay protection standard model. For example, a mapping relationship can be established between the setting value serial number and setting value name of the relay protection device and the setting values ​​in the setting value list. After establishing the mapping relationship, the serial number, name, and corresponding relay protection device of the setting value to be verified can be obtained.

[0064] In existing technologies, after obtaining the list of settings that need to be verified, the setting management function of the relay protection operation and maintenance control system can obtain the setting serial number, setting name, and the relay protection equipment to which the setting belongs, and remotely access the setting of relay protection equipment in each plant. However, due to the lack of information integration platform support, the various functional modules are relatively independent and exist in information silos, lacking coordination. It is still necessary to manually conduct a general survey of each plant, bay, and device to determine whether relay protection equipment exists, the relay protection standard model for the relay protection equipment, the communication status of the relay protection equipment, and the operating status, etc. Staff members find it difficult to adapt to and correctly use the information and services provided by each system. As a result, the information systems not only fail to improve operation and maintenance efficiency, but also increase the workload of operation and maintenance personnel and increase operation and maintenance costs.

[0065] The technical solution of this application embodiment, in conjunction with the existing relay protection equipment ledger, determines the relay protection equipment to which the set values ​​in the set value list belong, that is, the relay protection equipment that needs to be checked in this task.

[0066] The relay protection equipment ledger refers to the summary of information on relay protection equipment and related devices within the power system, supporting statistical management and retrieval of information such as equipment identification code, model, version, check code, program generation time, and equipment manufacturer of relay protection equipment.

[0067] Optionally, determining the relay protection equipment to be checked according to the setting list includes:

[0068] If the plant, bay, and device model in the setpoint list are consistent with the equipment ledger record of the plant, then the relay protection equipment in that plant shall be considered as the relay protection equipment to be verified.

[0069] For example, the system's equipment ledger management module can be used to review the ledger records of each plant and station to view the actual relay protection equipment models and their corresponding bays. This data can then be compared with the setting list to determine the specific plant and relay protection equipment requiring investigation. Furthermore, the ledgers of each plant and station can be used to view the actual relay protection standard models used by the relay protection equipment and their communication status.

[0070] S150. Verify the settings of the relay protection device according to the setting sequence number and setting name.

[0071] Specifically, after identifying the relay protection device, the setting value serial number and setting value name to be checked can be checked based on the target relay protection standard model used by the relay protection device. First, it can be determined whether the setting value to be checked is within the setting value inspection cycle. Setting values ​​within the cycle are retained, while setting values ​​outside the cycle are recalled.

[0072] The technical solution of this embodiment obtains a list of set values ​​to be verified and determines the category of relay protection equipment to which the set values ​​in the set value list belong; determines the target relay protection standard model corresponding to the set value list from candidate relay protection standard models belonging to the category of relay protection equipment; determines the set value sequence number and set value name of the set values ​​in the set value list based on the target relay protection standard model, and determines the relay protection equipment to be verified based on the target relay protection standard model; and verifies the set value of the relay protection equipment according to the set value sequence number and set value name. This embodiment of the application runs through the equipment ledger information management and set value management function modules of the relay protection operation and maintenance management system. First, the equipment to be checked is determined according to the equipment ledger information management module. Then, a mapping relationship is established between the set values ​​to be checked and the set values ​​stored in the set value management function based on the determined equipment to be checked. The specified set value items are verified, which greatly improves work efficiency and reduces the scope of manual verification.

[0073] Optionally, based on the above technical solution, step S150 preferably allows for verification based on the communication status and operating status of the relay protection equipment that needs to be checked.

[0074] Preferably, it may include:

[0075] Determine the setpoint inspection cycle of the relay protection equipment;

[0076] When the relay protection device is in operation, if the set value is detected to be within the inspection cycle, the set value within the inspection cycle is taken as a valid set value; otherwise, a call to the set value is performed to obtain a valid set value.

[0077] When the relay protection equipment is under maintenance, if the set value is detected to be within the inspection cycle and the set value is the set value before maintenance, then the pre-stored set value will be used as the effective set value.

[0078] If the relay protection device is in a communication interruption state, and the set value is within the inspection cycle and is the set value before the communication interruption, then the set value is taken as the effective set value.

[0079] Example 2

[0080] Figure 3This is a flowchart illustrating a relay protection setting verification method provided in Embodiment 2 of the present invention. Based on the above embodiments, this embodiment preferably adds the following addition: determining the relay protection voltage level corresponding to the relay protection equipment category; and verifying the accuracy of the relay protection voltage level, the relay protection equipment category, and the setting list. This embodiment is a further optimization of the above embodiments, and the same terminology has similar definitions, principles, processes, and technical effects as in the above embodiments. The method specifically includes:

[0081] S210. Obtain the list of settings that need to be verified, and determine the category of relay protection equipment to which the settings in the list belong;

[0082] S220. Determine the relay protection voltage level corresponding to the relay protection equipment category;

[0083] S230. Verify the accuracy of the relay protection voltage level, the relay protection equipment category, and the setting list;

[0084] The relay protection voltage can be the protection voltage of the object protected by the relay protection device, and the relay protection voltage level can be a voltage range used to ensure the normal operation of the protected object. The protected device can be a line or the load of electrical equipment on the line.

[0085] Optionally, the setting list may include the relay protection voltage of the corresponding relay protection device, and the relay protection voltage is determined according to the setting list. Alternatively, since the setting values ​​of relay protection devices of the same type have certain similarities, the relay protection voltage level of the relay protection device can be inferred based on experience. Specifically, the operator can preset the relay protection voltage of the relay protection device in the system, and after determining the setting list, determine the relay protection voltage by querying the preset information. Alternatively, after determining the setting list, the relay protection voltage can be determined through the system's intelligent matching technology.

[0086] Next, the accuracy of the relationship between the relay protection voltage level, the relay protection equipment category, and the setting list needs to be verified. Optionally, the accuracy verification of the relay protection voltage level, the relay protection equipment category, and the setting list includes:

[0087] Based on the rated parameters of relay protection devices in the relay protection device network access information database, the accuracy of the relay protection voltage level, the relay protection device category, and the setting list is verified.

[0088] If the verification fails, the setting list and / or the relay protection device category shall be corrected based on the rated parameters of the relay protection device.

[0089] The relay protection equipment network access information database can refer to the information database that the relay protection equipment reports to the management department when it is manufactured, or it can refer to the information database that the relay protection equipment backs up when it enters the power grid. This includes information such as the equipment identification code, model, version number, check code, production time, equipment manufacturer, supported setting range, and rated setting of the relay protection equipment.

[0090] The rated parameters of the relay protection equipment can be obtained by consulting the network access information database of the relay protection equipment. This allows for verification of whether the determined relay protection voltage level, the relay protection equipment category, and the setting value list correspond. If the verification is abnormal, the setting value list and / or the relay protection equipment category are corrected based on the rated parameters of the relay protection equipment. This generates a relay protection equipment category and setting value list that fully match the relay protection equipment in the network access information database. For settings that do not match the determined relay protection equipment category during the verification process, they can be removed from the list and recorded for subsequent manual verification.

[0091] S240. Determine the target relay protection standard model corresponding to the setting list from the candidate relay protection standard models belonging to the relay protection equipment category;

[0092] S250. Based on the target relay protection standard model, determine the setting value serial number and setting value name of the setting value in the setting value list;

[0093] S260. Determine the relay protection equipment that needs to be checked based on the aforementioned setting list;

[0094] S270. Verify the settings of the relay protection device according to the setting sequence number and setting name.

[0095] Optionally, after performing setting verification on the relay protection device based on the setting value sequence number and setting value name, the method further includes:

[0096] A message prompting the staff to review the verification results is generated.

[0097] Specifically, the verification results can be obtained by checking the setpoint list, relay protection equipment, the corresponding relay protection standard model for each relay protection equipment, the valid setpoints of each relay protection equipment stored in the relay protection operation and maintenance management system, and the output setpoint investigation results based on the relay protection equipment's operating status and communication status.

[0098] The output can include the plant name, relay protection device name, relay protection device model, relay protection device version, settings to be verified (serial number, name), valid settings, called settings, setpoint call time, remarks, etc. Devices under maintenance or with communication interruptions can be listed separately for further manual verification. Afterwards, reminders can be sent to staff via mobile phone, SMS, email, etc., for their review.

[0099] The technical solution of this embodiment can automatically link the equipment ledger information management and setting value management function modules of the relay protection operation and maintenance management system. It can verify the accuracy of the relay protection voltage level, the relay protection equipment category, and the setting value list. Then, it can intelligently identify the relay protection equipment category and setting value list that have passed the verification by performing relay protection standard model matching and setting value intelligent matching technology. It can automatically recall relay protection equipment that has no setting value record in the system, and sort out the setting value credibility according to the on-grid operation status, and list the credible setting values ​​and the list that need further manual verification, which greatly improves work efficiency and reduces the scope of manual verification.

[0100] Optionally, Embodiment 2 of the present invention also provides a schematic diagram of a relay protection setting verification process in a specific example, see [link to schematic diagram]. Figure 4 .

[0101] The specific implementation steps are as follows:

[0102] 1. Determine the list of relay protection equipment to be checked, and determine the category of the relay protection equipment to be checked and the range of its voltage level based on the required verification values.

[0103] 1) Verify the correctness of the required protection category, setting item list, and voltage level information;

[0104] The system compares the relay protection equipment with the relay protection equipment network access information database in the system to determine the correctness of the verification work content and generates a relay protection equipment category and setting list that fully matches the relay protection equipment in the relay protection equipment network access information database.

[0105] 2) Determine the standard models of relay protection involved in the verification setting list;

[0106] By using fuzzy recognition and intelligent matching technologies, the set values ​​in the standard models of relay protection devices belonging to the same category are analyzed to determine the target standard models of relay protection involved in the investigation, as well as the serial number and name of the set value item to be investigated in the set value dataset of the model.

[0107] 3) Based on the standard models of relay protection involved in the investigation, compile a list of relay protection devices that need to be investigated;

[0108] Using the system's equipment ledger management function module, the actual relay protection standard models used by the protection equipment of each plant are compared with the target relay protection standard models identified above, forming a list of specific plants, specific equipment, and their operating and communication status to be investigated.

[0109] 2. Verify the validity of the system settings.

[0110] Optionally, Embodiment 2 of the present invention also provides a flowchart illustrating the verification of the validity of a system setting in a specific example, see [link to flowchart]. Figure 5 .

[0111] The specific implementation steps are as follows:

[0112] 1. Determine the operating status;

[0113] Verify the communication status of the device under investigation and the operation and maintenance status of the relay protection equipment.

[0114] 2. Verification of the validity of the set value;

[0115] a. For operating equipment, according to the setpoint inspection cycle of the setpoint management module, check the setpoints stored in the system within the inspection cycle and use them as valid setpoints (the setpoint management inspection module determines the correctness of the setpoints);

[0116] b. For operating equipment, if the set value stored in the system has exceeded the set value inspection cycle, the current set value of the current area will be summoned. The set value after successful summoning will be used as the effective set value. If the summoning fails three times in a row, the corresponding set value item will not be filled in and manual verification is required. The note "Pending manual verification" will be added.

[0117] c. For equipment under maintenance, the set values ​​stored in the system that are within the set inspection cycle and are set values ​​before maintenance are considered valid set values, with the note "before maintenance";

[0118] d. For equipment under maintenance, the setpoints stored in the system are the setpoints during the maintenance period. List the current setpoints and the reference setpoints, and note "Under Maintenance";

[0119] e. For devices that are experiencing communication interruptions, the system stores the corresponding setpoints within the set inspection cycle, retrieves the corresponding setpoints recorded by the system, and notes "communication interruption".

[0120] f. For devices that are experiencing communication interruptions, if the set values ​​stored in the system have exceeded the set inspection cycle or there are no set value records in the system, the corresponding set value item should not be filled in and manual verification is required. The note should be "Communication interrupted, pending verification".

[0121] Example 3

[0122] Figure 6The diagram shown is a schematic representation of the relay protection setting verification device provided in Embodiment 3 of the present invention. The specific structure of the device is as follows:

[0123] It includes a category acquisition module 610, a model determination module 620, a set value determination module 630, an equipment determination module 640, and a set value verification module 650.

[0124] The category acquisition module 610 is used to acquire a list of settings that need to be verified and to determine the category of relay protection equipment to which the settings in the list belong.

[0125] The model determination module 620 is used to determine the target relay protection standard model corresponding to the setting list from the candidate relay protection standard models belonging to the relay protection equipment category;

[0126] The setting value determination module 630 is used to determine the setting value serial number and setting value name of the setting value in the setting value list based on the target relay protection standard model;

[0127] The device determination module 640 is used to determine the relay protection devices that need to be checked based on the setting list;

[0128] The setting verification module 650 is used to perform setting verification on the relay protection equipment according to the setting sequence number and setting name.

[0129] This application embodiment runs through the equipment ledger information management and setting value management function modules of the relay protection operation and maintenance management system. First, the equipment to be investigated is determined according to the equipment ledger information management module. Then, a mapping relationship is established between the setting value to be checked and the setting value stored in the setting value management function based on the determined equipment. The specified setting value items are checked, which greatly improves work efficiency and reduces the scope of manual verification.

[0130] As an optional implementation, the equipment determination module is specifically used to identify the relay protection equipment in the plant as the relay protection equipment to be verified if the plant, bay, and device model in the setting list are consistent with the equipment ledger record of the plant.

[0131] As an optional implementation, the setting verification module is specifically used to verify the communication status and operating status of the relay protection equipment as needed.
