[0001] The present application relates to the technical field of power systems, and particularly to a fault recording method, device, electronic device, and storage medium. Background Art

[0002] In a power system, a fault recorder is a device that collects, records, and analyzes electrical parameters (such as current, voltage, and switch quantity) of the power system. It can record the change process of electrical parameters before and after a large disturbance in the power system, as well as record the action behavior of relay protection and safety automatic devices, thereby providing assistance for disturbance analysis and fault handling. As the "black box" for recording power grid faults or abnormal conditions, the fault recorder is an important basis for power grid fault analysis.

[0003] Currently, the sampled values of analog quantities and switch quantities in a substation can be converted into digital quantities, and the IEC 60044-8 protocol is used as the data sending protocol to transmit to the fault recorder on the receiving side.

[0049] In a power system, a fault recorder is a secondary device for substation relay protection. A fault recorder is a device that collects, records, and analyzes electrical parameters (such as current, voltage, and switch signals) of the power system. It can record the change process of electrical parameters before and after a large disturbance in the power system, as well as record the action behaviors of relay protection and safety automatic devices, thus providing assistance for disturbance analysis and fault handling. As the "black box" for recording power grid faults or abnormal conditions, fault recording equipment is an important basis for power grid fault analysis.

[0050] With the popularization of the intelligent substation solution characterized by the digitization of analog quantity sampling and the networking of data transmission, the sampled values of analog quantities and switch quantities in the substation are converted into digital quantities and transmitted to the fault recorder. The device extracts the current, voltage analog quantities, and switch quantities from the messages for recording. During the digital development process of the substation, two digital access methods have emerged. One is the access method based on the sampled value SV data of ICE 61850-9-2 and the Generic Object Oriented Substation Events GOOSE data of Ethernet, and the other is the access method based on the IEC 60044-8 protocol of serial communication and a custom frame format.

[0051] In some application scenarios, for example, in order to improve the fault recording effect, users will adjust the number of bytes occupied by the sampled value of the electrical parameter in the data frame, transform the standard FT3 frame format adopted by the IEC 60044-8 protocol into a custom frame format, and send the data frame based on the custom frame format of the IEC 60044-8 protocol. In this way, for each custom frame format, users need to write corresponding parsing programs for the fault recorder, which is cumbersome for users and has low development efficiency. Moreover, in order to cope with different application scenarios, different parsing programs need to be loaded for the produced fault recorders, which is not conducive to the standardization of products.

[0052] Based on this, in various embodiments of the present application, the second electronic device generates a first data frame according to electrical parameters and a first mapping table, and sends the first data frame to the first electronic device, where the first mapping table is used to describe at least one bit corresponding to the electrical parameters in the data frame. The first electronic device receives the first data frame sent by the second electronic device, and checks the second identifier of the mapping table stored in the first electronic device based on the first identifier to obtain a check result. When the check result indicates that there is a second identifier matching the first identifier in the first electronic device, the first electronic device determines the electrical parameters in the first data frame based on the first mapping table by calling a set component. In the related art, for each data frame sent in a custom frame format, the user needs to write a corresponding parsing program for the fault recorder, resulting in low development efficiency. In the above solution, based on the mapping table in the first electronic device that matches the mapping table identifier corresponding to the data frame, the bit corresponding to the electrical parameters in the data frame is determined by calling a set component, so that the first electronic device can determine the electrical parameters in the data frame. In this way, regardless of whether the received data frame is in a custom frame format or a standard frame format, the first electronic device can determine the electrical parameters in the data frame. In other words, the user does not need to write a corresponding parsing program for the first electronic device for each custom frame format, thereby improving the development efficiency.

[0053] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0054] Figure 1 The following is a schematic flowchart of the implementation of the fault recording method provided by the embodiments of the present application. The embodiments of the present application provide a fault recording method applied to a first electronic device, where the first electronic device has the function of fault recording, including but not limited to a fault recorder. As Figure 1 shown, the fault recording method includes:

[0055] Step 101: Receive a first data frame sent by a second electronic device.

[0056] The first data frame is generated according to electrical parameters and a first mapping table, and carries a first identifier of the first mapping table.

[0057] Step 102: Check the second identifier of the mapping table stored in the first electronic device based on the first identifier to obtain a check result.

[0058] Step 103: When the verification result indicates that there is a second identifier in the first electronic device that matches the first identifier, call a set component to determine the electrical parameters in the first data frame based on the first mapping table.

[0059] The first mapping table is used to describe at least one bit position corresponding to the electrical parameter in the data frame.

[0060] The first electronic device receives the first data frame sent by the second electronic device, verifies the second identifier in the mapping table stored in the first electronic device based on the first identifier carried in the first data frame. When the verification result indicates that there is a second identifier in the first electronic device that matches the first identifier, the first mapping table is stored in the first electronic device. The first electronic device calls a set component to run a set program, and imports the first mapping table stored in the first electronic device into the set program. The set program determines the corresponding electrical parameters based on the corresponding relationship between the electrical parameters described in the first mapping table and at least one bit position in the data frame, based on the information of at least one bit position in the first data frame. Here, the first electronic device can record the determined electrical parameters to record the change process of the electrical parameters before and after the occurrence of a large disturbance in the power system, thereby providing assistance for disturbance analysis and fault handling.

[0061] Among them, combined with the specific needs of the fault recording scenario, for example, in order to obtain better results, parameters such as the sampling rate are usually adjusted, and correspondingly, the number of bytes occupied by the sampled value of the electrical parameter in the data frame is adjusted. For this reason, the custom frame format is described in text form through a frame format document. The electronic device cannot directly parse the frame format document, and the frame format document is converted into a mapping table that can be parsed by the electronic device. The component represents the interface of the program. By calling a set component, a set program is run to at least implement the parsing of the data frame. Here, calling a set component causes the electronic device to run a set program. Through a determined program, the program determines the electrical parameters of the data frame according to the imported mapping table. That is to say, the electronic device can determine the electrical parameters in the data frames of various frame formats through a determined program, without writing corresponding parsing programs for the electronic device for each custom frame format.

[0062] Here, the first electronic device represents the receiving-side electronic device of the data frame, and the second electronic device represents the sending-side electronic device of the data frame. The mapping table is stored in the electronic device in the form of a file, and there can be one or more mapping tables stored in the electronic device. Each mapping table corresponds to an identifier. It can be seen that there can be multiple second identifiers in the first electronic device.

[0063] The electrical parameter is the actual parameter value of the electrical parameter. In the fault recording of the power system, the electrical parameter represents the actual parameter value of the electrical parameter of the power system.

[0064] When describing the correspondence between electrical parameters and data frame information, the first mapping table can describe the relationship between the data frame and the electrical parameters by bytes. In other words, the first mapping table can combine bytes and bit positions to describe the position of the electrical parameters corresponding in the data frame. For example, the byte sequence number of the virtual input channel 001 is 4, and the bit position is 0.

[0065] When determining the electrical parameters in the data frame based on the mapping table, the electrical parameters can be directly extracted from the data frame, or the corresponding bit data can be processed (such as decoded) to obtain the electrical parameters.

[0066] In the above solution, based on the mapping table in the first electronic device that matches the mapping table identifier corresponding to the data frame, the bit positions corresponding to the electrical parameters in the data frame are determined by calling the set components, enabling the first electronic device to determine the electrical parameters in the data frame. In this way, regardless of whether the received data frame is a custom frame format or a standard frame format, the first electronic device can determine the electrical parameters in the data frame. In other words, based on the mapping table in the first electronic device that matches the mapping table identifier corresponding to the data frame, the user does not need to write a corresponding parsing program for the first electronic device for each custom frame format, thereby improving the development and maintenance efficiency of the electronic device.

[0067] Moreover, through the set interface, the corresponding set program is run in the electronic device to enable the electronic device to support the compatible access of the IEC 60044-8 protocol based on serial communication and the custom data frame format, thereby being generally applicable to various fault recording scenarios and improving the standardization degree of the production of electronic devices.

[0068] As mentioned above, in some application scenarios, the user will adjust the number of bytes occupied by the sampled value of the electrical parameter in the data frame, and transform the standard FT3 frame format adopted by the IEC 60044-8 protocol into a custom frame format. In one embodiment, before receiving the first data frame sent by the second electronic device, the method further includes:

[0069] Updating the first mapping table in the first electronic device.

[0070] Here, the way to update the first mapping table can be to replace the existing mapping table or to store the mapping table additionally.

[0071] Inputting the corresponding first mapping table to the first electronic device to update the mapping table stored in the first electronic device. In this way, when the first electronic device receives the first data frame sent by the second electronic device, it can determine the correct electrical parameters based on the updated first mapping table.

[0072] In one embodiment, the identifier of the mapping table includes at least one of the following:

[0073] Table check code;

[0074] Version number.

[0075] Among them, the table check code can be set and can be generated based on algorithms such as the check code algorithm and the SnowFlake algorithm. In this embodiment, the method for generating the table check code is not limited.

[0076] The version number represents the version of the mapping table, and the custom frame format corresponding to the mapping table can be determined according to the version number.

[0077] When verifying the identifier of the mapping table, it can be based on the table check code, based on the version number, or based on both the table check code and the version number.

[0078] In practical applications, the identifier of the mapping table can be determined according to at least one of the following methods: the file name of the mapping table, the table name of the mapping table, and / or at least one record in the table of the mapping table. Taking the determination of the identifier of the mapping table according to the file name of the mapping table as an example, the file name of the mapping table is in the following format: Portxx_xxxxxxxxx_Vx.x_xxxx.xlsx. Among them: the Portxx field represents the access fiber optic port number; the xxxxxxxxx field is a mnemonic description; the Vx.x field is the version number; the xxxx field is the table check code.

[0079] In one embodiment, the mapping table is used to describe at least one bit position in the data frame corresponding to at least one of the following electrical parameters:

[0080] Optical fiber parameters;

[0081] Analog quantity; and / or,

[0082] Virtual switch quantity.

[0083] Here, the mapping table may include at least one worksheet, and each worksheet corresponds to one or more electrical parameters.

[0084] In practical applications, it can be set that the mapping table includes three worksheets, namely the optical fiber parameter table, the analog quantity table, and the virtual switch quantity table, corresponding to the optical fiber parameters, the analog quantity, and the virtual switch quantity respectively.

[0085] Such as Figure 2 As shown in the schematic diagram of the optical fiber parameter table, the optical fiber parameter table includes four columns of attributes: short address, parameter name, value, and unit. Here, the short address represents the internal parameter variable name of the electronic device.

[0086] Such as Figure 3Schematic diagram of the analog scale shown. The analog value table includes multiple columns of attributes: serial number, analog channel number, channel name, starting byte number, number of bytes occupied, virtual switch quantity, channel input, analog type, analog flag, phase flag, unit.

[0087] As Figure 4 Schematic diagram of the virtual switch quantity table shown. The virtual switch quantity table includes multiple columns of attributes: serial number, switch quantity channel number, channel name, byte number, bit position, channel input, signal type, channel flag, contact type, trigger permission.

[0088] In one embodiment, the method further includes:

[0089] In the case where the verification result indicates that there is no second identifier matching the first identifier in the first electronic device, output a prompt message.

[0090] When the verification result indicates that there is no second identifier matching the first identifier in the first electronic device, the electronic device outputs a prompt message. In this way, the user can input the mapping table in a timely manner based on the prompt message, and the electronic device can receive the input mapping table in a timely manner, thus ensuring the fault recording effect of the electronic device. At the same time, the workload of manually verifying the mapping table is reduced, thereby improving the development efficiency.

[0091] Figure 5 Schematic diagram of the implementation process of the fault recording method provided by the embodiment of the present application. The embodiment of the present application provides a fault recording method, which is applied to a second electronic device, where the second electronic device includes but is not limited to electrical secondary devices. It includes:

[0092] Step 501: Generate a first data frame according to the electrical parameters and the first mapping table.

[0093] Step 502: Send the first data frame to the first electronic device.

[0094] Wherein, the first mapping table is used to describe at least one bit corresponding to the electrical parameter in the data frame.

[0095] The second electronic device generates a first data frame based on the electrical parameters according to the corresponding relationship between the electrical parameters described by the first mapping table and at least one bit in the data frame, and sends the first data frame to the first electronic device. Among them, the first data frame carries a first identifier, and the first identifier is used for the device that receives the first data frame to verify the mapping table and determine the matching mapping table.

[0096] Here, the first electronic device represents the receiving-side device of the data frame, and the second electronic device represents the sending-side electronic device of the data frame. The mapping table may include at least one worksheet, and each worksheet corresponds to one or more electrical parameters. The mapping table is stored in the electronic device in the form of a file, and there may be one or more mapping tables stored in the electronic device. Each mapping table corresponds to an identifier. Obviously, there may be multiple identifiers in the second electronic device.

[0097] Based on the mapping table in the electronic device, the second electronic device generates and sends a first data frame by calling a set component. Here, the component represents the interface of the program. By calling the set component, the set program runs to at least implement the parsing of the data frame. Here, calling the set component causes the electronic device to run the set program. That is to say, here it is a definite program that can implement the parsing of the custom frame format according to the mapping table. The set component in the second electronic device and the set component in the first electronic device may be the same or different.

[0098] The electrical parameter is the actual parameter value of the electrical parameter. In the fault recording of the power system, the electrical parameter represents the actual parameter value of the electrical parameter of the power system.

[0099] When describing the correspondence between the electrical parameter and the data frame information, the first mapping table can describe the relationship between the data frame and the electrical parameter by bytes. In other words, when the first mapping table is used to describe at least one bit position corresponding to the electrical parameter in the data frame, the relationship between the data frame and the electrical parameter can be described in combination with bytes and bit positions.

[0100] In the above solution, based on the electrical parameter and the first mapping table describing at least one bit position corresponding to the electrical parameter in the data frame, the second electronic device generates the first data frame and sends it to the first electronic device. In this way, regardless of whether the sent data frame is a custom frame format or a standard frame format, based on the mapping table corresponding to the frame format, the second electronic device can generate the data frame corresponding to the electrical parameter. In other words, the user does not need to write a corresponding parsing program for the electronic device for each custom frame format, thereby improving the development and maintenance efficiency of the electronic device.

[0101] In an embodiment, the first data frame carries a first identifier of the first mapping table; the first identifier is used to verify the mapping table.

[0102] In this way, after receiving the first data frame, the first electronic device can verify the stored mapping table based on the first identifier carried in the first data frame.

[0103] In an embodiment, before generating the first data frame according to the electrical parameter and the first mapping table, the method further includes:

[0104] Update the first mapping table in the second electronic device.

[0105] Here, the way to update the first mapping table can be to replace the existing mapping table or to store the mapping table additionally.

[0106] Input the corresponding first mapping table to the first electronic device to update the mapping table stored in the first electronic device. In this way, when the first electronic device receives the first data frame sent by the second electronic device, it can determine the correct electrical parameters based on the updated first mapping table.

[0107] Next, in combination with application embodiments, the present application will be further described in detail.

[0108] In the early stage of each engineering design, the user will record the frame format in text form to form a frame format document, and write parsing programs corresponding to the frame format for the transmitting-side electronic device and the receiving-side electronic device respectively according to the frame format document. However, in actual applications, since the transmitting-side electronic device and the receiving-side electronic device of the data frame are usually not from the same manufacturer, when writing programs based on non-standard frame format documents, the programs written by both sides may not correspond, resulting in the receiving-side electronic device being unable to obtain electrical parameters from the data frame.

[0109] Moreover, for each custom frame format, a corresponding parsing program needs to be written, and the newly written parsing program needs to undergo a large number of tests, which is cumbersome for the user to operate.

[0110] In addition, since the number of bytes occupied by the sampled value of the electrical parameter in the data frame also needs to be adjusted according to requirements during use, that is to say, the parsing program needs to be updated in real time, and the maintenance cost is relatively high.

[0111] In the practical process, due to the mismatch between the parsing programs on the transmitting side and the receiving side, the parsed data cannot be used, resulting in low efficiency in the engineering design, equipment manufacturing, and engineering construction of intelligent substations.

[0112] Based on this, Figure 6 FIG. shows a schematic flowchart of custom frame format processing provided by an application embodiment of the present application.

[0113] First, a custom frame format description method based on frame bit mapping.

[0114] The determined custom frame format document table of IEC 60044-8, as shown in Table 1 and Table 2 below, describes the frame format in text form, and the electronic device cannot directly parse it. The content that needs to be recorded in the frame format document is mapped into a format that can be parsed by the electronic device according to the bit position through the frame bit mapping table and stored in the form of an Excel table.

[0115] Table 1 Custom Frame Format Table of IEC 60044-8

[0116]

[0117] Table 2 Supplementary Explanation Table of the Status Word in Table 1

[0118]

[0119] The frame bit mapping table includes three worksheets, as Figures 2 to 4 shown.

[0120] When the transmitting optical fiber of the ICE 60044-8 data with a communication rate of 20 Mb / s, a data block length of 4 bytes, a sampling rate of 100000 Hz, and a custom multi-byte sampling value accesses the fault recording receiving port 01, the parameter settings of the mapping table are as Figure 2 shown.

[0121] The analog quantity to be acquired is a 24-bit analog quantity sampling value defined by the 2nd, 3rd, and 4th bytes in Table 1. The 24-bit analog quantity sampling value is interpreted as starting byte sequence number 1, occupying 3 bytes, and the parameters are as shown in Table Figure 3 shown. The analog quantity sampling value can also be 8 bits, 16 bits, or 32 bits;

[0122] The switch quantity to be acquired is the 5th and 6th bytes in Table 1. The 16-bit status information is called a virtual switch quantity (the 16-bit status information is made up of 2 bytes and is called a virtual switch quantity). Each bit represents a different meaning. The byte sequence numbers of the mapping table are 4 and 5 respectively, and the bit positions are 0 to 7. At the same time, the virtual switch quantity value at the position occupied by this byte in the analog quantity setting value table is set to 1, indicating that this position is occupied by the virtual switch quantity and cannot be processed as analog quantity data.

[0123] The R & D personnel on the sending side process the custom frame structure and parameter mapping described in words into a formatted table according to the above method, that is, the mapping table. When storing the mapping table, the file name can be set in the following format: Portxx_xxxxxxxxx_Vx.x_xxxx.xlsx. Among them: the Portxx field represents the access optical fiber port number; the xxxxxxxxx field is the mnemonic description; the Vx.x field is the version number; the xxxx field is the table check code. The electronic device can parse the formatted content described by Excel.

[0124] Then, the implementation process of the custom frame format is described.

[0125] For a custom frame format based on IEC 60044-8, establish the corresponding standard format and process. At the initial stage of engineering design, after the frame format is agreed upon by both parties, the R & D personnel of the sending-side electronic device convert the frame format document into a fixed-format frame bit mapping table using the bit mapping method, and the sending party is responsible for unified maintenance.

[0126] The table is designed in a fixed format, and the frame content is filled in according to the data types of bits, bytes, words, or 4 bytes. With a fixed format, a set program can be used for parsing and processing, eliminating the need to separately compile a receiving program for each project.

[0127] During project implementation, the sending-side device imports this table, and the program automatically sends data according to the table content. Similarly, the receiving-side device also imports the same formatted table, and the standard program parses this table and extracts the frame content according to the table format. Each time the frame format is adjusted, the sending party is responsible for revising the table content, generating a check code, and forming a version number. The engineering personnel on-site for commissioning of both the sending side and the receiving side respectively check the version numbers of the imported mapping tables.

[0128] After importing the mapping table, through processing, the electronic device makes the sent frame content include the table check code and version number. If the table imported by the receiving-side device is inconsistent with the check code or version of the table imported by the sending party, the receiving-side device will automatically identify and give a prompt or warning.

[0129] In the application embodiment of this application, according to a unified description method of a custom frame format based on bit mapping, a corresponding implementation process of a custom frame format based on bit mapping is adopted. Based on the bit mapping table, the fault recording is processed with the data frame of the custom frame format, which is used to implement fault recording and realize the compatible access of the IEC 60044-8 protocol based on serial communication and the custom data frame format.
