[0048] The technical solution of the present invention is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical solution of the present application, rather than limitations on the technical solution of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other.

For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0050] Embodiment 1:

[0051] Figure 1 This is a flow chart of a method for generating a secondary safety measure list for a power system in the first embodiment of the present invention. This flow chart only shows the logical sequence of the method described in this embodiment. In other possible embodiments of the present invention, different methods may be used without conflict. Figure 1 The steps shown or described are accomplished in the order shown.

[0052] The method for generating a secondary safety measure list for a power system provided in this embodiment can be applied to a terminal and can be executed by a personal computer, a server or other device. The device can be implemented by software and / or hardware. Figure 1 The method of this implementation specifically includes the following steps:

[0053] Obtain the physical relationship SPCD and logical relationship SCD of the power system, and make a digital model based on the physical relationship and logical relationship;

[0054] Acquire the isolation strategy, execution sequence strategy, statement template strategy and safety measure ticket template of the power system, configure the digital model according to the isolation strategy, execution sequence strategy, statement template strategy and safety measure ticket template strategy, and obtain the configured digital model;

[0055] Input the work tasks and maintenance equipment information into the configured digital model to generate a secondary safety measures sheet.

[0056] Among them, the isolation strategy mainly refers to the isolation strategy of physical components such as soft pressure plates, hard pressure plates, optical fibers, circuit breakers and switch handles. After the statement template strategy and the safety measures ticket template strategy are configured in the digital model, a ticketing style library and a general statement library consisting of a general statement library and a regional statement library should be generated in the digital model, and the secondary safety measures sheet should be output based on the ticketing style library and the general statement library.

[0057] It is not difficult for those skilled in the art to see that the main safety hazard in the power system comes from electrical out-of-control, and the propagation of electricity between different components has strong traceability and predictability in physical and logical relationships. Therefore, this embodiment mainly uses physical and logical relationships to produce a digital model, which improves the efficiency of generating secondary safety measures and lays the foundation for the formulation of secondary measures for multi-dimensional safety protection.

[0058] In this embodiment, in the process of generating secondary safety measures for the power system, the secondary safety dimensions are divided into four dimensions: isolation, execution order, statement template, and safety measures ticket template. The isolation strategy mainly corresponds to the complex physical relationships in the power system, and the execution order strategy mainly corresponds to the complex logical relationships in the power system. The digital model is configured according to the isolation strategy and the execution order strategy respectively, which improves the generation efficiency of these two safety dimensions when generating the secondary safety measures ticket, ensuring that the main safety dimensions can be covered.

[0059] When the digital model is configured according to the isolation strategy and the execution order strategy to generate a secondary safety measures sheet, the two security dimensions are difficult to coordinate in terms of statements, which can easily lead to confusion and may cause the secondary safety measures sheet to not conform to industry terminology habits. At the same time, the readability and language logic of a secondary safety measures sheet is also a long-ignored security dimension. Therefore, this embodiment also configures the digital model according to the statement template strategy and the safety measures ticket template strategy, wherein the statement template is used to organize the security steps for different isolation strategies and execution order strategies, replacing the original manual process and greatly improving efficiency; and the safety measures ticket template sorts and outputs the steps organized in the statement.

[0060] After inputting the work tasks and maintenance equipment information into the configured digital model, the digital model formulates corresponding isolation strategy steps and execution sequence strategy steps according to the mapping of the physical and logical relationships between the work tasks and maintenance equipment information, and then outputs the secondary safety measures sheet according to the configured statement template and safety measures ticket template, thereby improving the generation efficiency of the secondary safety measures sheet of the power system and the various safety dimensions covered, thereby improving safety.

[0061] Embodiment 2:

[0062] This embodiment provides a method for generating a secondary safety measures list for a power system. This embodiment is optimized on the basis of the first embodiment to improve the technical effect and refine the technical solution. For the contents not fully described in this embodiment, please refer to the first embodiment.

[0063] As one of the embodiments, the industry currently has a means of refining the physical and logical relationships of the power system with high accuracy and efficiency, but there is a lack of industry experience in making digital models based on physical and logical relationships, and digital models may be modeled through semi-manual and semi-automatic methods; the logical relationship can be extracted by identifying the electrical circuits in the electronic drawings, and it is difficult to make mistakes; but the existing drawing recognition technology still has loopholes in identifying the physical relationships in the electronic drawings, and manual work may be used when it comes to the physical restoration of cutting-edge electrical phenomena. Therefore, there may be many errors in restoring the physical relationship of the power system in the digital model through electronic drawings. In order to ensure the accuracy of the key physical relationships in the digital model, a digital model is made according to the physical and logical relationships, including obtaining a physical relationship verification module; using the physical relationship verification module to verify the "interval-panel-equipment" relationship, "substation-small room" relationship, "panel-equipment / accessory" relationship and "device-accessory" relationship in the digital model, respectively, to obtain the verification result; in response to the verification result being an error, the digital model is remade or the digital model is corrected.

[0064] The digital model verified by the physical relationship verification module has good accuracy in physical relationships.

[0065] As one of the embodiments, in the process of making a digital model according to physical and logical relationships, this embodiment at least includes the step of building a model data table. This embodiment mainly builds a model data table according to logical relationships, and the purpose of building a model data table is to facilitate the acquisition of the logical relationship data of the virtual circuit and the soft pressure plate from the model data table; the logical relationship data of the virtual circuit and the soft pressure plate are input into the automatic configuration tool, and the automatic configuration tool is used to build the logical relationship between the virtual circuit and the soft pressure plate in the digital model; wherein the automatic configuration tool can be implemented in other forms known in the art, which will not be repeated here; the logical relationship of the soft pressure plate in the digital model is identified, and a first interactive interface is constructed based on the identification result; the staff member corrects the logical relationship between the virtual circuit and the soft pressure plate in the first interactive interface; then, the correction configuration parameters are obtained from the first interactive interface, and the logical relationship of the soft pressure plate is corrected using the correction configuration parameters.

[0066] As one embodiment, the automatic configuration tool can be based on Checksum calculation tool SafeCheckTool Development.

[0067] As mentioned above, the identification of electrical circuits in electronic drawings can be used to construct logical relationships in digital models, and the correction steps mentioned above are intended to perform later modifications to the logical relationships. Correction of logical relationships using the above method only requires personnel to input correction configuration parameters in the first interactive interface, which simplifies the process and improves efficiency.

[0068] As one embodiment, the work tasks and maintenance equipment information are input into the configured digital model to generate a secondary safety measures list, including:

[0069] Extract the strategy library from the configured digital model. The strategy library can be regarded as the mapping of work tasks and maintenance equipment information in the configured digital model.

[0070] Find the physical relationship mapping and logical relationship mapping related to the maintenance equipment in the configured digital model;

[0071] Generate configuration mapping of maintenance equipment according to work tasks and related physical relationship mapping and logical relationship mapping;

[0072] Generate a policy template in the policy library based on the configuration mapping;

[0073] Obtain a region selection, determine a corresponding statement template in a policy template according to the selected region, output multiple security measure tickets according to the statement template, and organize the security measure tickets as a secondary security measure sheet.

[0074] By extracting the policy library and generating policy templates based on configuration mapping and the policy library, the efficiency of generating secondary security measures sheets can be improved.

[0075] When the power system is a substation, different substations have different execution sequence strategies. In this embodiment, the execution sequence strategy is formulated based on the substation type as the main distinction and the safety measure type as the subdivision means.

[0076] Obtain the substation type sequence and formulate execution order strategies for different substation types, taking the substation types of smart substation and conventional substation as examples.

[0077] In response to the substation type being a smart station, the smart station often has certain automatic safety controls for current and voltage circuits. Therefore, in the early stage of executing the sequential strategy, attention is paid to hardware safety, including formulating maintenance steps for the hard pressure plate in each maintenance equipment according to the safety measures data table; in response to the completion of the formulation of the maintenance steps for the hard pressure plate in each maintenance equipment, traversing all types of safety measures, and formulating safety measures for the interlocking circuits of each maintenance equipment according to the priorities corresponding to the safety measures data table based on different safety measures types; in response to the completion of the formulation of the interlocking circuit safety measures, formulating safety measures for the sampling circuits of each maintenance equipment according to the priorities corresponding to the safety measures data table based on different safety measures types; in response to the completion of the formulation of the sampling circuit safety measures, formulating process safety measures for each maintenance equipment according to the priorities corresponding to the safety measures data table based on different safety measures types.

[0078] In response to the substation type being a conventional station, all types of safety measures are traversed, and according to the different safety measures types and the priorities corresponding to the safety measures data table, the interlocking circuit safety measures steps for each maintenance equipment are formulated; conventional stations need to strengthen the safety measures in terms of current and voltage, so in response to ending the formulation of the interlocking circuit safety measures steps, according to the different safety measures types and the priorities corresponding to the safety measures data table, the current circuit safety measures steps and the voltage circuit safety measures steps for each maintenance equipment are formulated; in response to ending the formulation of the current circuit safety measures steps and the voltage circuit safety measures steps, according to the different safety measures types and the priorities corresponding to the safety measures data table, the process safety measures steps for each maintenance equipment are formulated.

[0079] As one embodiment, the process of formulating the execution sequence strategy should also include formulating the power outage type (power outage and no power outage).

[0080] In summary, this embodiment provides an outline for formulating an execution order strategy based on the usage characteristics and security weaknesses of intelligent stations and conventional stations.

[0081] As one embodiment, the method of obtaining the safety measures data table includes:

[0082] Obtain the work task sequence, maintenance equipment sequence and the type of safety measures for each work task. The types of safety measures are generally divided into three categories: technical transformation, defect elimination and verification;

[0083] Calculate the maintenance equipment involved in each work task based on physical and logical relationships;

[0084] According to the type of safety measures, all types of maintenance equipment under each work task are prioritized. The priorities include the first-level maintenance equipment directly involved in the work task, the second-level maintenance equipment that has a direct virtual loop association with the first-level maintenance equipment, and the remaining maintenance equipment is the third-level maintenance equipment.

[0085] The priority of executing secondary safety measures for maintenance equipment is also a safety dimension. By reasonably grading the maintenance equipment, the final generated secondary safety measures list will focus on maintenance equipment with high priority.

[0086] As one of the embodiments, the statement template strategy example is as follows:

[0087] "Settings: 'Record %IED setting setting area: Area';

[0088] Soft pressure plate: 'Record all soft pressure plates of %IED: %GOOSE sends soft pressure plate (throw, withdraw), %GOOSE receives soft pressure plate (throw, withdraw), %SV receives soft pressure plate (throw, withdraw), % functional soft pressure plate (throw, withdraw)';

[0089] Hard Strap: 'Record all hard strap positions in front of the %IED screen: %FunHardStrap (throw, withdraw), %TestHardStrap (throw, withdraw), %ExHardStrap (throw, withdraw)'. ”

[0090] As one embodiment, the data structure of the security measure ticket in the ticketing style library is as follows:

[0091] "Public Information:

[0092] "Company"

[0093] "Num" (ticket number)

[0094] "Principal"

[0095] "Signer"

[0096] "Executor"

[0097] "ExeGuardian"

[0098] "Restorer"

[0099] "ReGuardian"

[0100] "BeOpePer" (BeOpePer)

[0101] "BeTestPer" (BeTestPer)

[0102] "AfOpePer" (AfOpePer)

[0103] "AfTestPer" (finishing confirmation and maintenance personnel)

[0104] }

[0105] Security ticket information:

[0106] "Work"

[0107] "testDevName" (name of the device to be repaired)

[0108] }

[0109] "OriRecord" (Original Status Record): {

[0110] "Item"

[0111] Type

[0112] "Content" (content, can support image and string input)

[0113] "BeWorkCon" (confirmation of work start, 0, 1)

[0114] "AfWorkCon" (confirmation of completion of work, 0, 1)

[0115] }

[0116] "Measure": {

[0117] "Item"

[0118] Type

[0119] "Content"

[0120] "Execute" (execution confirmation, 0, 1)

[0121] "Restore" (restore confirmation, 0, 1)

[0122] }".

[0123] As one embodiment, the digital model should include a functional soft pressure plate sub-model according to the logical relationship, identify the functional soft pressure plate device based on the configuration software, and correct the configuration parameters through the interactive interface. Define the extended protection function type in combination with the identified device, and set the database element node attributes to complete the creation of this model.

[0124] As one of the embodiments, the isolation strategy of the soft pressure plate is sent using GOOSE (Generic Object-Oriented Substation Event). An example of the isolation strategy is as follows:

[0125] “(1) All GOOSEs of the maintenance equipment send soft pressure plates. The calculation method is: all GOOSEs corresponding to the maintenance equipment GOOSEPUB send soft pressure plates;

[0126] (2) GOOSE sending soft pressure plates from maintenance equipment to operating equipment is calculated as follows: all GOOSE sending soft pressure plates corresponding to the GOOSEPUB of the relevant operating equipment in the maintenance equipment;

[0127] (3) All GOOSEs of the running device send soft pressure plates. The calculation method is: all GOOSEs corresponding to the running device GOOSEPUB send soft pressure plates;

[0128] (4) GOOSE sends soft pressure plates from the operating equipment to the maintenance equipment. The calculation method is: all GOOSE sends soft pressure plates corresponding to the relevant maintenance equipment GOOSEPUB in the operating equipment;

[0129] (5) The GOOSE soft pressure plates sent from the transmission test equipment to the secondary operating equipment are calculated as follows: all GOOSE soft pressure plates sent by the corresponding GOOSEPUBs of the relevant secondary operating equipment in the transmission test equipment.

[0130] As one of the embodiments, when the substation type is an intelligent station and the safety measure type is defect elimination or verification, the safety measure step of the inter-jump circuit includes sequentially calling the "GOOSE sending soft pressure plate from maintenance equipment to operating equipment", "GOOSE sending soft pressure plate from operating equipment to maintenance equipment", "GOOSE receiving soft pressure plate from operating equipment to maintenance equipment", "GOOSE receiving soft pressure plate from maintenance equipment to operating equipment", and "direct jump optical fiber from maintenance equipment to operating equipment" strategies, which are intended to calculate all maintenance equipment inter-jumping operating equipment-related GOOSE sending soft pressure plates, operating equipment inter-jumping maintenance equipment-related GOOSE sending soft pressure plates, operating equipment inter-jumping maintenance equipment-related GOOSE receiving soft pressure plates, maintenance equipment inter-jumping operating equipment GOOSE receiving soft pressure plates, and maintenance equipment inter-jumping operating equipment direct jump optical fiber. If the safety measure type is technical transformation, then the step of "technical transformation equipment device power circuit breaker" is called again after the above steps, which is intended to calculate the device power circuit breaker model data corresponding to the technical transformation equipment.

[0131] As one of the embodiments, when the substation type is a smart station and the safety measures type is technical transformation, defect elimination and verification, the interlocking circuit safety measures steps include sequentially calling the "export hard pressure plate from maintenance equipment to operating equipment", "export hard pressure plate from operating equipment to maintenance equipment", "export hard pressure plate of maintenance equipment", and "function hard pressure plate of maintenance equipment" strategies, aiming to calculate all the maintenance equipment interlocking operating equipment-related export hard pressure plates and operating equipment interlocking maintenance equipment-related export hard pressure plates. If the type of safety measure is only technical transformation, then in the subsequent steps of the above steps, the strategies of "maintenance equipment to operating equipment tripping terminal", "operating equipment to maintenance equipment tripping terminal", "maintenance equipment to operating equipment start failure terminal", "operating equipment to maintenance equipment start failure terminal", "maintenance equipment to operating equipment decompression locking terminal", "operating equipment to maintenance equipment decompression locking terminal", "maintenance equipment to operating equipment bus coupling jump terminal", "operating equipment to maintenance equipment bus coupling jump terminal", "maintenance equipment to operating equipment bus coupling hand-closing terminal", "operating equipment to maintenance equipment bus coupling hand-closing terminal", and "power supply side device power circuit breaker" are called again to calculate the device power circuit breaker model data corresponding to the technical transformation equipment.

[0132] As one of the embodiments, when the substation type is an intelligent station and the intelligent station has a merging unit, the sampling loop safety measures step includes sequentially calling "SV receiving soft pressure plate from operating equipment to maintenance equipment" and "direct sampling optical fiber from maintenance equipment to operating equipment". When the substation type is a conventional station, the sampling loop safety measures step is divided into voltage and current loop safety measures steps. For the current loop safety measures step, if the safety group measures type is defect elimination, verification and technical transformation, the current loop safety measures step includes "current terminals of maintenance equipment" and "current terminals of maintenance equipment to operating equipment" strategies, which are designed to calculate the terminal number of the same panel cabinet and the same terminal row in ascending order. If the safety group measures type is only technical transformation, the "current terminals of operating equipment to maintenance equipment" strategy is called after the above steps to calculate the terminal number of the same panel cabinet and the same terminal row in ascending order. For the voltage circuit safety measures step, if the safety group measures type is defect elimination, verification and technical transformation, then the voltage circuit safety measures step is "voltage terminals from maintenance equipment to operating equipment". If the safety group measures type is only technical transformation, then "voltage terminals from operating equipment to maintenance equipment" is called, aiming to calculate the terminal number and the same terminal row in the same panel cabinet and sort them from small to large.

[0133] If the substation type is smart station and the safety measure type is technical transformation, the process safety measure steps include “(1) calculating all directly connected running equipment based on the current maintenance equipment, defining the transmission test equipment with expanded maintenance scope, and calling the calculation model data of ‘transmission test equipment maintenance hard pressure plate’;

[0134] (2) Sequentially call the 'GOOSE sending soft pressure plate from the transmission test equipment to the second-class operating equipment', 'GOOSE receiving soft pressure plate from the transmission test equipment to the second-class operating equipment' and 'direct jump optical fiber from the transmission test equipment to the second-class operating equipment' to calculate the GOOSE sending and receiving pressure plates and optical fiber disconnection points that need to be disconnected from the second-class operating equipment during the transmission test process.

[0135] If the substation type is a conventional substation, the safety measure type is only technical transformation, and the process safety measure steps include "power supply side device power circuit breaker" and "power supply side device control power circuit breaker". The safety measure type is defect elimination, verification and technical transformation, and the process safety measure steps include sequentially calling the "maintenance equipment to operating equipment fault recording terminal" and "operating equipment to maintenance equipment fault recording terminal" strategies to calculate model data.
