[0052] The embodiments of the present invention provide a line protection debugging outline template instantiation method, a line protection debugging outline template instantiation device, an electronic device and a storage medium, which are used to solve or partially solve the technical problem that most of the debugging outline editing work in the existing related technology is completed manually by testers, and the process is time-consuming and labor-intensive, which greatly reduces the debugging efficiency of substation secondary equipment.

[0053] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] In order to enable those skilled in the art to better understand the technical solution provided by the embodiment of the present invention, some technical features involved in the solution are briefly described first:

[0055] SCD file: A standardized file format used to describe the configuration and communication settings of all IEDs (Intelligent Electronic Devices) in a smart substation. In an SCD file, common information includes basic information such as the name, number, and physical topology of the substation, as well as detailed properties and configurations of each device (such as circuit breakers, transformers, switches, etc.), and network-related information such as communication configuration, communication protocols, and communication interfaces. SCD files can be used in various stages of smart substation design, construction, commissioning, and operation and maintenance.

[0056] MMS (Manufacturing Message Specification): In smart substations, MMS messages are a standard protocol for communication. MMS messages can carry various types of data, including control commands, status reports, event records, etc. The station control layer and the bay layer use MMS messages to perform object-oriented modeling of actual devices, thereby enabling interoperability between different manufacturing devices in a network environment.

[0057] GOOSE (Generic Object Oriented Substation Event): A message passing mechanism. It can be used to transmit real-time protection information between multiple IEDs in a smart substation. It can also be used to transmit circuit breaker status and other key control signals.

[0058] SV (Sampled Values): The value obtained by sampling electrical quantities through sensors in the power system and digitizing them. The SV protocol is a communication protocol for transmitting analog sampled values. The SV protocol is mainly used for high-speed transmission of analog data between IEDs in smart substations, such as current, voltage and other measurement values.

[0059] As an example, currently, before debugging equipment, the debugging personnel will edit and modify the general debugging outline for each different device to generate a specific debugging outline. During the actual debugging, the debugging personnel will debug according to the debugging outline of the specific device and fill in the debugging results. However, with this debugging method, since most of the debugging outline editing work needs to be done manually by the debugging personnel, the process is time-consuming and labor-intensive, which greatly reduces the debugging efficiency of substation secondary equipment.

[0060] Therefore, one of the core inventive points of the embodiment of the present invention is: in view of the deficiencies in the prior art, a method for digitizing and instantiating a line protection debugging outline template for an intelligent substation is proposed. On the one hand, by establishing a universal debugging object model, the secondary equipment models of various manufacturers can be integrated to solve the differentiation problem of the same type of secondary equipment models from different manufacturers (such as equipment line protection, intelligent terminals, merging units, integrated intelligence and other device models). On the other hand, through manual modeling, the line protection debugging outline document is converted into a universal digital debugging outline template, and templated debugging objects, test items, test logic and associated signal points are defined, and combined with the substation SCD file, the line protection debugging outline instance is automatically instantiated and generated, so that the debugging outline template can be edited once and used by multiple devices, thereby greatly reducing the workload of debugging outline editing and improving the debugging efficiency of substation line protection devices.

[0061] Reference Figure 1 , shows a flowchart of a method for instantiating a line protection debugging outline template provided by an embodiment of the present invention, which may specifically include the following steps:

[0062] Step 101, obtaining an SCD file, a debugging outline, and a plurality of general debugging object models of a smart substation, wherein the debugging outline corresponds to at least one test item, and each of the test items corresponds to a test logic;

[0063] In practical applications, first of all, it is necessary to build a universal debugging object model for each different type of debugging object. For example, for debugging objects of the measurement and control device class, build a universal debugging object model, and for debugging objects of the protection device class, build another universal debugging object model. Then, according to the standards of each debugging object, establish a unified universal information point, integrate the differentiated information points of each manufacturer, and form a dictionary library.

[0064] The debugging object standard refers to the substation secondary equipment information model standard, which may include device standards such as substation equipment information model technical specifications, relay protection information specifications, relay protection and related secondary equipment information description specifications, etc.

[0065] Specifically, universal debugging object models corresponding to different types of debugging objects are established, and universal information points of each universal debugging object model are established respectively; each universal information point is mapped and associated with the device model signal point actually corresponding to the smart substation to form a dictionary library; the dictionary library is used to describe the mapping association relationship between the universal information point and the device model signal point actually corresponding to the smart substation.

[0066] Among them, the debugging objects are mainly the line interval secondary equipment in the smart substation, and the line interval secondary equipment can include line protection devices of various voltage levels, measurement and control devices, universal voltage level line intelligent terminals, merging units, and integrated intelligence. General information points include station control layer MMS signal points, process layer GOOSE signal points, and SV signal points. Each signal point is identified by a unique name, and a mapping relationship is established with the model signal points of each manufacturer and model device.

[0067] Furthermore, the debugging outline template document of the line protection of the smart substation can be obtained, and by parsing the debugging outline template document of the line protection, text, table and other information can be extracted to form a digital debugging outline table and text content (i.e., debugging outline). The basic attributes of the debugging outline can also be automatically analyzed based on the keywords in the document. Among them, the basic attributes can mainly include information such as the device type, interval type, voltage level, and device set of the line protection device measured by the debugging outline. The basic attributes are used to compare and match the debugging outline with the line protection device.

[0068] The line protection commissioning outline template is a document template used to guide the commissioning of line protection devices. This type of document usually includes the purpose, scope, preparation, commissioning steps, test items, acceptance criteria, etc. of the commissioning, so that the line protection device can work correctly and reliably.

[0069] For each test item in the digital commissioning outline, a general line protection test process, i.e., general test logic, can be written using general information points. For test items that cannot be written using general test logic, a specific line protection test process, i.e., dedicated test logic, can be written for a specific model of IED.

[0070] Among them, the test items of line protection can mainly include protection input and output test, distance protection setting value inspection, zero sequence protection setting value verification, longitudinal differential protection verification, etc. The test logic (i.e. the test process) can mainly include pressure plate, control word throw-in and throw-out operation, voltage and current output state sequence, action output state sequence, result judgment logic, etc.

[0071] It is understandable that, although in most cases, the writing of the test logic follows the order of the pressure plate, the control word throw-in and throw-out operation, the voltage and current output state sequence, the action output state sequence, and the result judgment logic. However, in actual applications, the test logic does not need to be written strictly in this order. Those skilled in the art can make adjustments according to actual test requirements. It is understandable that the present invention is not limited to this.

[0072] Due to the differences in protection equipment of different manufacturers, for some special test items, the line protection test methods and processes of each manufacturer are different, so it is impossible to use the general test logic to write the test process. In this case, a specific test process can be written for each specific manufacturer and model of IED.

[0073] For example, a relay line protection device of a certain manufacturer has a steady-state differential I-stage protection function, while other manufacturers' protection devices do not have this function. Therefore, it is necessary to write a specific test process for the steady-state differential I-stage protection of the relay line protection device of this manufacturer.

[0074] For example, the distance protection function algorithms of line protection devices from different manufacturers are different. Therefore, for the distance protection test item, different test procedures need to be written for the devices of different manufacturers.

[0075] In the specific implementation, for each test item in the debugging outline, we can first determine whether the test item is a general test item; if so, we will reference the general information point and write the general line protection test process (general test logic) of the test item; if not, we will define the test item as a special test item, determine the special model IEDs corresponding to the special test item, and write the special test logic of the special test item under different special model IEDs. Therefore, for a specific test item, we can write specific test processes (special test logic) for different models of line protection devices.

[0076] Step 102, determining at least one target debugging object that conforms to the general debugging object model according to the SCD file and the debugging outline, and generating debugging outline instances of each of the target debugging objects respectively through instantiation;

[0077] In this step, the debugging object of the line protection debugging outline is instantiated based on the SCD file, and a debugging outline instance for a specific line protection device (that is, the target debugging object obtained through screening) is generated.

[0078] Specifically, according to the SCD file and the debugging outline, at least one target debugging object that conforms to the general debugging object model is determined, which can be: parsing the SCD file, analyzing the basic properties of all line interval secondary equipment in the smart substation, and screening out all line protection devices from all line interval secondary equipment; through comparison and matching, screening out at least one target debugging object that is consistent with the basic properties of the debugging outline and corresponds to the general debugging object model from each line protection device.

[0079] More specifically, the SCD file is imported and parsed. According to the IED name of the line bay secondary device in the SCD, the voltage level, device type, bay type and other attributes of each line bay secondary device are analyzed. Based on the analysis results, all line protection devices are filtered out. By comparing and matching the attributes of the screened line protection devices with the basic attributes of the debugging outline such as voltage level and device set (which can be regarded as constraint attributes here), all line protection devices that meet the conditions (i.e., the device type, bay type, voltage level, and device set are all consistent) are further screened out as target debugging objects. Then, debugging outline instances are generated for these target debugging objects (actual line protection devices).

[0080] Step 103: instantiate all debugging objects to be instantiated that are associated with the test logic of the debugging outline instance, and instantiate all information points to be instantiated that are referenced in the test logic.

[0081] In this step, the main task is to instantiate all debugging objects to be instantiated (i.e., IEDs to be instantiated) associated in the test logic of the debugging outline instance according to the virtual connection of the line protection device, as well as instantiate all information points to be instantiated referenced in the test logic, and instantiate the information points to specific signal point references in the SCD.

[0082] In a specific implementation, all debugging objects to be instantiated associated in the test logic of the instantiated debugging outline instance can be: first, all debugging objects to be instantiated associated in the test logic of the debugging outline instance are recorded as set S1; based on the SCD file, the virtual connection of the target debugging object is analyzed, and all associated secondary devices having a virtual connection relationship with the target debugging object are determined, which are recorded as set S2; then the device type of each device in set S1 and set S2 is compared one by one, and when there is a successful match between the device type of the target debugging object to be instantiated and the target associated secondary device, the target debugging object to be instantiated is replaced with the target associated secondary device.

[0083] More specifically, for the line protection debugging outline instance obtained in the above steps, all the IEDs to be instantiated (general debugging objects to be instantiated) associated in the test logic of the debugging outline instance are recorded as set S1. Based on the SCD file, the virtual connection of the actual line protection device (target debugging object) is analyzed, and all IED devices (associated secondary devices) that have a virtual connection relationship with the line protection are found, recorded as set S2, and the device type of each IED device is recorded. There is at most one device of the same type in the line interval. For example, there is at most one intelligent terminal, merging unit, or integrated intelligent device. Therefore, the device type of each device in sets S1 and S2 can be compared one by one. When the device types are the same, it is considered that the match is successful, that is, the instantiation is successful. Replace the IED to be instantiated (target debugging object to be instantiated) with the instantiated IED (target associated secondary device with the same device type as the target debugging object to be instantiated).

[0084] Then instantiate all the information points to be instantiated that are referenced in the test logic. The process can be specifically as follows: first determine all the information points to be instantiated that are referenced in the test logic; then, based on the mapping relationship between the general information points described in the dictionary library and the corresponding device model signal points in the smart substation, for each information point to be instantiated, traverse all the actual device model signal points associated with the information point to be instantiated, and compare the information point to be instantiated with each actual device model signal point one by one; when there is a successful match between the target information point to be instantiated and the target actual device model signal point, replace the target information point to be instantiated with the target actual device model signal point.

[0085] Among them, for each information point to be instantiated, the dictionary library describes the mapping relationship between the information point and the actual corresponding device model signal point in the smart substation. Therefore, all actual device model information points associated with the information point to be instantiated are traversed, and the device manufacturer, device model, device version, and signal reference information in the information point to be instantiated are compared with each actual device model signal point. When the information is the same, it is considered that the match is successful. At this time, the general information point to be instantiated is replaced with the instantiated information point.

[0086] For a specific test item, it may be impossible to instantiate the current test logic based on the general debugging object model. According to the above content, specific test procedures are written for different types of line protection devices in step 101. Therefore, in this case, according to the manufacturer and model of the actual line protection device corresponding to the debugging outline instance to which the current debugging object belongs, a matching dedicated test logic can be selected as the test procedure of the specific test item. Then, referring to the relevant process of instantiating all the information points to be instantiated referenced in the test logic introduced in the above steps, all the information points to be instantiated referenced in the dedicated test logic are instantiated.

[0087] In a specific implementation, when the current test logic cannot be instantiated based on the general debugging object model, a dedicated debugging outline instance of the current debugging object is generated by instantiation; the target dedicated model IED and the target dedicated test item to which the dedicated debugging outline instance belongs are determined, and the target dedicated test logic matching the target dedicated model IED is screened out from multiple dedicated test logics corresponding to the target dedicated test item; all information points to be instantiated referenced in the target dedicated test logic are instantiated.

[0088] In an embodiment of the present invention, a method for digitizing and instantiating a line protection debugging outline template for a smart substation is proposed. On the one hand, by establishing a universal debugging object model, the secondary equipment models of various manufacturers can be integrated to solve the differentiation problem of the same type of secondary equipment models from different manufacturers (such as equipment line protection, intelligent terminals, merging units, integrated intelligence and other device models). On the other hand, the line protection debugging outline document is converted into a universal digital debugging outline template through manual modeling, and templated debugging objects, test items, test logic and associated signal points are defined. In combination with the substation SCD file, the line protection debugging outline instance is automatically instantiated and generated, so that the debugging outline template can be edited once and used by multiple devices, thereby greatly reducing the workload of debugging outline editing and improving the debugging efficiency of substation line protection devices.

[0089] For better explanation, refer to Figure 2 , showing a schematic diagram of the overall process of a line protection debugging outline template instantiation method provided by an embodiment of the present invention. It should be pointed out that this embodiment only briefly describes the general process of line protection debugging outline template instantiation, and the specific implementation process of each step can be understood by referring to the relevant content in the aforementioned embodiment, which will not be described here. It can be understood that the present invention is not limited to this.

[0090] Step 201: Establish a general debugging object model and general information points to form a dictionary library;

[0091] Step 202: parsing the line protection debugging outline template document to form a digital debugging outline;

[0092] Step 203: Write the test logic of each test item in the debugging outline;

[0093] Step 204: Determine whether instantiation can be performed based on a general method; if not, jump to step 205; if yes, jump to steps 206 to 208;

[0094] Step 205: Enable instantiation in a dedicated manner; jump to step 208;

[0095] Step 206: Screening the target debugging object and generating a debugging outline instance;

[0096] Step 207: instantiate the debugging object to be instantiated associated in the debugging outline instance test logic;

[0097] Step 208: Instantiate the information points to be instantiated that are referenced in the test logic.

[0098] For ease of understanding, in combination with the foregoing embodiments, an embodiment of the present invention is described below by using a specific example.

[0099] Step 1: Establish a general debugging object model for line bay secondary equipment of smart substation.

[0100] Firstly, for different types of debugging objects, a universal debugging object model for line interval secondary equipment is constructed, which can mainly include 220kV line protection device (named P_L220_N), universal intelligent terminal device (named I_O00_N), and universal merging unit device (named M_O00_N).

[0101] Then, according to the standards of the new generation of autonomous and controllable devices, general information points are established, mainly including MMS signal points (parameters, set values, pressure plates, telesignaling, telemetering, remote control, etc.) of line protection, GOOSE sending and receiving signal points, GOOSE sending and receiving signal points of intelligent terminals, and SV sending signal points of merging units.

[0102] These common information points are then associated and mapped with the signal points of the corresponding device model in the actual SCD file of the smart substation to form a dictionary library.

[0103] Step 2: Parse the line protection debugging outline template document.

[0104] By parsing the line protection debugging outline template document, extracting text, tables and other information in the document, a digital debugging outline (including tables, text content and other information) is formed. According to the keywords in the document, the basic attributes of the debugging outline template can be automatically analyzed. Specifically, it includes the voltage level and device type of the line protection device measured in the debugging outline.

[0105] Specifically, the program can automatically read the table text information in the document to form a digital debugging outline. And automatically analyze the basic attributes of the debugging outline template such as voltage level and device type according to the keywords in the document. For example, when identifying the voltage level, fuzzy matching can be performed based on the keywords 750kV, 500kV, 330kV, 220kV, 110kV, 66kV, 35kV, 110kV, and 380V. The analysis of other basic attributes is similar and will not be repeated here.

[0106] Step 3: For each test item in the digital debugging outline, use common information points to write common line protection test logic.

[0107] Specifically, several test processes can be set to flexibly edit and combine test logic. When writing test logic, signal points (ie, general information points) of standard signals of the general debugging object model can be referenced.

[0108] For example:

[0109] (1) Manual confirmation: output test results through manual selection;

[0110] (2) Platen / control word launch and retreat: Automatic launch and retreat of the platen / control word device is realized through MMS communication;

[0111] (3) GOOSE sending: sending GOOSE position change message;

[0112] (4) State sequence: realize the sending of voltage and current digital / analog state in sequence;

[0113] (5) Logical judgment: You can edit the logical formula arbitrarily to judge the test results;

[0114] by Figure 3 Take the distance protection setting test item of 220kV line protection as an example.

[0115] For example, the action behavior under the setting value of 105% of section I - the test process of phase A fault writing is as follows:

[0116] first step:

[0117] Pressure plate / control word throw and withdraw: P_L22_0N$ENA$distance protection soft pressure plate$Val=ON; P_L22_0N$CW$distance protection stage I$Val=ON;

[0118] Step 2:

[0119] Output normal voltage and current Ua1=57.735∠0°, Ub1=57.735∠-120°, Uc1=57.735∠120°, Ia1=Ib2=Ic3=0, duration 5s;

[0120] Step 3:

[0121] Output fault state voltage and current Ua1=10∠0°, Ub1=57.735∠-120°, Uc1=57.735∠120°, Ia1=6 / 1.05 / P_L22_0N$SET$ground distance I stage constant value $Val, Ib2=Ic3=0, duration 80ms;

[0122] Step 4:

[0123] Logical judgment: [P_L22_0N$TRII$Ground distance stage I action$Act]=0&& [P_L22_0N$TRII$Phase distance stage I action$Act]=0&& I_O00_0N$GTX$A phase circuit breaker position$Val=0.

[0124] Step 4: Generate a debug outline instance.

[0125] Import the SCD file and analyze the voltage level, device type, bay type, and device set of the IED according to the IED name. Then use the 220kV line protection device as the general debugging object model screening condition, and filter out all the line protection devices that meet this condition from all the IEDs parsed from the SCD file. In this example, the four line protection devices P_L2201A, P_L2201B, P_L2202A, and P_L2202 can be filtered out. Then, for these four 220kV line protection devices, the corresponding debugging outline instances can be generated respectively.

[0126] Step 5: Instantiate all IEDs associated in the test logic of the debug outline instance.

[0127] Specifically, take the P_L2201A line protection debugging outline example obtained in step 4 as an example. According to the SCD file, it is analyzed that the IEDs having a virtual connection relationship with the P_L2201A line protection device include the intelligent terminal I_L2201A and the merging unit M_L2201A.

[0128] The IEDs to be instantiated associated with the distance protection setting verification test process in step 3 are the line protection P_L220_N and the intelligent terminal I_O00_N. Therefore, the line protection P_L220_N should be instantiated as the line protection P_L2201A, and the intelligent terminal I_O00_N should be instantiated as the intelligent terminal I_L2201A.

[0129] Step 6: Instantiate all the information points to be instantiated that are referenced in the test logic, and instantiate the information points to reference specific signal points in the SCD.

[0130] Specifically, for the information point "P_L22_0N$SET$ground distance segment I constant value $Val" in step 3, the dictionary library describes the mapping relationship between the general information point and the signal point ground distance segment I constant value of the actual IED device model (ie, line protection P_L2201A).

[0131] By traversing all mappings of the ground distance I section constant value of the general information point, you can find the mapping that is consistent with the manufacturer, device model, and device version information of the line protection P_L2201A device. Finally, the information point to be instantiated "P_L22_0N$SET$ground distance I section constant value $Val" is instantiated into the actual device model signal point "P_L2201A$SET$ground distance I section constant value $Val" by replacement. Record the specific signal reference associated with it: P_L2201APROT / PDIS1.GndStr.

[0132] According to the above method, the common information points of all test items can be instantiated one by one.
