[0041] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0043] Currently, the relay protection and control devices for power and new energy systems vary across different countries and regions. Common distinguishing features include analog quantities, digital quantities, and system parameters, such as power supply voltage, system frequency, and PT / CT rated values, as shown in Table 1 below:

[0044] Table 1. Distinguishing Features of Domestic and International Power and New Energy Systems

[0045]

[0046] As shown in the table above, compared to China, foreign countries offer a wider variety of power supply voltages, input voltages, and voltage ratings. Furthermore, their human-machine interface and device export models differ. Therefore, traditional relay protection and control devices typically require hardware with varying voltage levels, system parameters, or ratings tailored to different countries, regions, and user needs. Simultaneously, corresponding fixed system parameters are matched in the software to achieve protection and control functions. This results in numerous hardware and software versions of traditional relay protection and control devices, making them difficult to manage. When user needs change, the corresponding hardware or software versions must be directly modified to meet those needs, leading to lengthy modification times.

[0047] To address the issues of numerous hardware and software versions and difficulties in modification in traditional relay protection measurement and control devices, this application provides a relay protection measurement and control system. This system can effectively solve the problems of developers facing heavy inventory pressure from managing multiple hardware versions and high development and maintenance costs for multiple software versions.

[0048] The following description, in conjunction with the accompanying drawings, provides an example of the relay protection measurement and control system provided in this application.

[0049] Figure 1 A schematic diagram of the relay protection measurement and control system provided in this application embodiment. See also... Figure 1 As shown, it includes a general-purpose hardware device 100 and a software configuration device 200. The general-purpose hardware device 100 includes multiple general-purpose boards.

[0050] The software configuration device 200 is configured to modularly encode the board drive function and the protection and control function to obtain a meta template file. The meta template file includes the board drive function module and the protection and control function module.

[0051] It also instantiates the meta template file to obtain a backup file, and obtains the driver file from the backup file according to the user's configuration instructions.

[0052] The general-purpose hardware device 100 is configured to store meta template files, backup files, and driver files, and to start the general board, board driver function, and protection and control function according to the driver files to realize the protection and control process of the device under test.

[0053] In this embodiment, multiple general-purpose boards are provided within the general-purpose hardware device 100, each used to implement different functions of the relay protection and control device, such as power supply, signal acquisition, central processing, or signal output. Each general-purpose board has multiple hardware types. For example, the power supply module has a wide range of power supply voltages from 24 to 250VDC. The packaged meta template file has six independent options for hardware types: 24V, 48V, 76V, 110V, 125V, and 220V, allowing users to select the corresponding power supply voltage as needed.

[0054] For example, in the implementation process of a typical complex-phase overcurrent protection and control device, corresponding required attributes can be added during modular programming for each type of board driver to drive the board, as shown in Table 2 below:

[0055] Table 2 Device Interface Attribute Definitions

[0056]

[0057] The software configuration device 200 modularizes the board drive function and protection and control function into a meta template file. The board drive function includes power supply options with multiple voltage types, such as 24V, 48V, 76V, 110V, 125V, and 220V, which are six independent power supply voltage types. The protection and control function module includes multiple logic functions, such as independent voltage recovery function and phase overcurrent protection function.

[0058] Then, the meta-template file is instantiated to obtain a backup file. The software configuration device 200 includes a board drive processing unit and a protection and control processing unit. The board drive processing unit is configured to instantiate the attribute configuration of the board drive function module; the protection and control processing unit is configured to instantiate the logical relationships of the protection and control function module. For example, the board drive function module includes power module voltage types, and the instantiated backup file has six options: 24V, 48V, 76V, 110V, 125V, and 220V, for the user to choose from. The protection and control function module includes overvoltage protection and phase overcurrent protection functions. In the instantiated backup file, the overvoltage protection relay and the phase overcurrent protection relay have established logical relationships (e.g., sequential operation). Then, according to the user's configuration instructions, the driver file is selected from the backup file. For example, if the user selects the 220V voltage type option, the power supply voltage type in the driver file will be 220V. The driver file and the backup file are then downloaded to the relay protection and control device.

[0059] For example, the modularization of protection and control functions can include basic modules such as analog quantity acquisition, setting value acquisition, event storage, three-phase over / under supply relays, phase quantity judgment, single-phase over / under supply relays, time delay relays, AND, OR, and NOT logic gates, as well as protection and control function modules configured from these basic modules. Among them, the extended relay adopts a general inverse time curve formula, and realizes a definite-time or inverse-time delay element by setting the parameter setting value. The formula is as follows:

[0060]

[0061] Among them, G represents the fault current I in current protection, and Gs represents the starting current Is. When 0 < G / Gs < 1, t is the reset time; when G / Gs > 1, t is the tripping time. A, B, C, p, and k are fixed parameter values. By setting the curve type fixed value, a definite-time limit or a standard inverse time limit curve or a user-defined curve can be selected. When the definite-time limit is selected, A = 0, and the delay fixed value is t = B × k; when the International Electro technical Commission (IEC) standard inverse time limit is selected, referring to the IEC inverse time limit curve specification, the corresponding coefficients are shown in Table 3 below; when the user-defined option is selected, the curve required by the user can be customized by setting the parameters A, B, C, p, and k.

[0062] Table 3 Curve Parameters of IEC Inverse Time Limit Curve

[0063] Inverse time-limited curve type A*k B*k P C IEC Normal Inverse 0.14 0 0.02 1 IEC is very inverse. 13.5 0 1 1 IEC Extreme Inverse 80 0 2 1

[0064] Download the backup file and the driver file to the hardware general device 100 and restart the hardware general device 100. Analyze the content of the driver file to start the general board, the board driver function, and the protection and measurement and control functions, so as to implement the protection and measurement and control process for the device under test. For example, through the 220V power supply voltage type in the driver file, the 220V power supply voltage connected to the relay protection measurement and control device is corresponded to supply power to the entire relay protection measurement and control device. Among them, the device under test includes primary equipment in power and new energy systems and equipment that appears in other application scenarios.

[0065] Exemplarily, the configuration file includes a meta-template file, a backup file, and a driver file.

[0066] The meta-template file is configured to store the modular content of the board driver function and the protection and measurement and control functions.

[0067] The backup file is configured to store the meta-template file and the instantiated content. The instantiated content includes the instantiated data of the board driver function and the protection and measurement and control functions.

[0068] The driver file is configured to store the instantiated data selected from the backup file according to the user's configuration instructions for use.

[0069] In this embodiment, the meta-template file stores the individual sub-modules within the board drive function module and the protection and control function module. The backup file stores the attribute configuration data of the sub-modules within the board drive function module and the logical relationships between them. This is for users to use when updating or upgrading the relay protection control device later. Because most or even all hardware types are modularly packaged, users only need to select the board and configure it within the software configuration device. When user needs change, the board selection and software configuration can be modified and adjusted, and a driver file can be generated based on the adjusted backup file. The driver file then drives the relay protection control device. For example, the backup file may contain all content such as input acquisition information, output execution information, interaction information between protection and control logic, settings, events, and waveform recordings. The driver file contains only the functions that the relay protection control device needs to load and run; that is, it only contains the functions that the user selects and configures to be used in the relay protection control device.

[0070] For example, the backup file includes a meta template file and instantiated content, the instantiated content including parameter units, data resource units, and logical units.

[0071] Parameter units are configured as instantiation parameters for storage systems, devices, and boards.

[0072] A data resource unit is configured to store instantiated data of a data resource.

[0073] The logical unit is configured as an instantiation of storage protection and measurement and control logic.

[0074] In this embodiment, the relay protection control device transmits information through a configuration file, that is, storing the meta-template file and instantiation information in the configuration file according to a predefined format. The general-purpose hardware device reads and parses the configuration file content to achieve information interaction with the software configuration device, as well as subsequent instantiation modifications or upgrades. The configuration file uses the extensible markup language (XML) file format. XML provides a method for describing things, capable of representing common data structures such as lists and trees, and has good extensibility; it stores structured data in plain text, allowing for free definition of attributes and hierarchical relationships. By adding tags to various things, the purpose of completely representing the attributes of things can be achieved. This application uses three XML files to implement the storage of configurable functional information:

[0075] (1) Meta template file (CellTemp.xml) is used to store various board drive function modules and protection and control function modules.

[0076] (2) Backup file (Cellcfg_backup.xml): The configurable software imports the meta template file. After the user instantiates the board, functions, and parameters according to their needs, a backup file containing the meta template file and the instantiation content is exported. The instantiation part includes: system and board parameters, named Parameter; data resources Const; and logical functions Logic: containing system logic.

[0077] (3) Driver file (Cellcfg.xml), used to store the drive information of the relay protection and control device, only contains the functions of the board that need to be put into operation. The specific functions are shown in Table 4 below:

[0078] Table 4 Function Table of Meta Template Files and Configuration Files

[0079]

[0080] For example, Figure 2 This is a schematic diagram of the configuration file XML format provided in the embodiments of this application, such as... Figure 2 As shown, the contents of the parameter unit, data resource unit, and logical unit in the configuration backup file are instantiated according to the user's actual needs.

[0081] For example, such as Figure 1 As shown, the general-purpose hardware device 100 includes multiple general-purpose boards such as a data acquisition module 101, a central processing module 102, and a data output module 103; the central processing module 102 is electrically connected to the data acquisition module 101 and the data output module 103 respectively.

[0082] The data acquisition module 101 is configured to acquire analog and digital signals from the device under test.

[0083] The central processing module 102 is configured to generate protection and control signals based on analog and digital signals.

[0084] The data output module 103 is configured to trip, alarm, or control the device under test based on protection and control signals.

[0085] In this embodiment, the data acquisition module 101 is used to acquire analog and digital signals from the device under test (DUT). For example, the analog signals can be analog signals such as system voltage and current acquired by a phase voltage transformer / current transformer (PT / CT), and the digital signals can be digital signals representing the status of primary equipment such as circuit breakers, isolating switches, and grounding switches. The central processing module 102 is used to generate protection and control signals based on the analog and digital signals. For example, it sends output signals based on input quantities to control the system to operate normally and complete various functions. The data output module 103 is used to trip, alarm, or control the DUT based on the protection and control signals. For example, it implements protection and control processes, sends digital output signals such as trip / close or alarm, and controls the DUT to trip or perform corresponding actions.

[0086] For example, such as Figure 1 As shown, the general-purpose hardware device 100 also includes a communication module 104, a human-computer interaction module 105, and a power supply module 106, all of which are electrically connected to the central processing module 102.

[0087] The communication module 104 is used for data transmission with other devices or network layers.

[0088] The human-computer interaction module 105 is used to display the device status and information, making it easier for staff to operate the machine.

[0089] Power module 106 is used to provide operating power for the entire system.

[0090] In the embodiments of this application, power and new energy systems currently commonly use wired communication, such as RJ485 electrical ports and LC / ST optical ports, as well as serial ports.

[0091] The aforementioned relay protection and control system encapsulates and modularizes protection and control functions and board driver functions through software configuration equipment to obtain meta-template files. These meta-template files are then instantiated to generate backup files. Based on user configuration commands, driver files are selected from the backup files. General-purpose hardware devices then activate the corresponding general-purpose boards, board driver modules, and protection and control modules according to the driver files, thus realizing the protection and control process for the device under test. When user requirements change, modifications can be made directly through the software configuration equipment, making changes convenient and simple.

[0092] Based on the relay protection measurement and control system provided in this embodiment, the relay protection measurement and control methods will be described in detail below.

[0093] For example, Figure 3This is a flowchart of the relay protection measurement and control system provided in the embodiments of this application, such as... Figure 3 As shown, a relay protection measurement and control method includes the following steps:

[0094] S201. The software configuration device modularizes the board drive function and protection and control function modules to obtain a meta template file. The meta template file includes the board drive function module and the protection and control function module.

[0095] S202. The software configures the device to instantiate the meta template file to obtain a backup file.

[0096] S203. The software configures the device to obtain the driver file from the backup file.

[0097] S204. The general hardware device starts the corresponding general board, board driver function and protection and control function according to the driver file to realize the protection and control process of the device under test.

[0098] In this embodiment, the software configuration device first modularly encodes the board driver function and protection and control functions to obtain a meta-template file, providing the foundation for the entire relay protection and control system. Then, the meta-template file is instantiated, that is, the attributes of the board driver function module are configured, and the logical relationships of the protection and control function module are configured, resulting in a backup file with all instantiated content. When the user uses the system, they input the required configuration commands, and based on these commands, select the appropriate instantiated content from the backup file to obtain the driver file. Finally, the general-purpose hardware device starts the general board, board driver function, and protection and control functions according to the driver file, thereby realizing the protection and control process of the device under test for user use.

[0099] For example, instantiating a meta template file to obtain a backup file includes:

[0100] Instantiate the property configuration of the board driver function module.

[0101] And to instantiate the logical relationships of the protection and control function modules.

[0102] In this embodiment, after a user configures their requirements in a software configuration device (e.g., a computer), they obtain a backup file and a driver file. Both the backup file and the driver file are downloaded to a general-purpose hardware device. The driver file directly drives the logic relationships within the general-purpose board, the board's driver functions, and the protection and control functions. The backup file is typically stored in the general-purpose hardware device. When a user needs to change the configuration of the relay protection and control device, the user re-enters new configuration commands. The software configuration device then modifies the configuration based on the backup file, obtaining both the backup file and the new driver file. Finally, the relay protection and control device is restarted based on the driver file.

[0103] For example, the relay protection measurement and control method further includes:

[0104] Various configuration permissions can be set according to different user roles. The higher the user role level, the more configuration permissions are available.

[0105] In this embodiment, the user roles using the software configuration device may include: manufacturer, super user, engineer, and operator, etc. The rights granted by the software configuration device differ for each user role; for example, the level of user role configuration permissions includes: manufacturer > super user > engineer > operator. Specifically, as shown in Table 5 below:

[0106] Table 5 Example of User Role Permissions

[0107]

[0108] The following is an exemplary description of the relay protection and control system of this application. When a user needs to construct a relay protection and control device, they can obtain the driver file by selecting specific instantiation content from the backup file through software configuration. This includes, for example, the power supply voltage type in the board driver module and the overcurrent protection function in the protection and control module. The backup file, driver file, and meta-template file are all in XML flow description format. Upgrades can also be completed by referring to the configuration files of existing similar projects. The following describes the configurable process using the overcurrent protection configuration process as an example; the configuration methods for other functions are the same.

[0109] After selecting the appropriate device boards based on site requirements, configure the terminal attributes of each board to complete the device's power supply and interface functions. Configure the parameters of the third LED in the device by configuring its attributes, as shown in Table 6 below. The device's output configuration is similar. Index represents the specific LED object; Latch indicates whether to hold; Color is the color, which can be configured as red, green, or yellow.

[0112] The parameters for the first input are configured by setting the input attributes, as shown in Table 7 below. Index is the corresponding specific input data, HoldSet is the anti-jitter time, and HoldVoltage is the start-up voltage level.

[0115] The parameters of the first analog quantity are configured by configuring the analog quantity attributes, as shown in Table 8 below. Star Point refers to the voltage polarity. The default value is FromObject from bus to line, and ToObject from line to bus. TAIn1 / 2 are the primary and secondary values ​​of the rated voltage, respectively.

[0118] Figure 4 This is a flowchart illustrating the configuration of the overcurrent protection for the complex voltage phase provided in an embodiment of this application. Figure 4 As shown, by configuring the encapsulated functional modules to implement the overcurrent protection under complex voltage conditions, the instantiation process of the device's internal software functions can be completed. First, modules such as "Analog Input I3p", "Three-phase Overcurrent Relay", and "Phase Number Judgment" are instantiated to implement the phase current protection starting element. Modules such as "Analog Input U3p", "Three-phase Undercurrent Relay", and "OR Logic" are instantiated to implement the overcurrent protection element starting judgment. At the same time, overcurrent protection element enabling / disabling elements and phase current protection enabling / disabling elements are instantiated. By combining the overcurrent protection element starting element and the phase overcurrent protection element, the overcurrent protection function with complex voltage blocking is obtained.

[0119] This relay protection and control system can be applied to feeder protection in a specific engineering project, including protection functions such as phase overcurrent, zero-sequence overcurrent, voltage, frequency, failure, and reclosing; control functions such as switch synchronization and remote control; and telemetry functions such as protection analog quantities and measurement analog quantities. Through the factory output of typical general configuration files, on-site users can add and upgrade functions according to their temporary needs without changing the program; the configuration can be changed simply by configuring the equipment through software.

[0120] The relay protection and control system described in this application requires only one set of universal boards from the same series for factory hardware. Combined with software configuration equipment, the board driver function and protection and control functions are modularized, allowing for selective configuration for different applications. Users do not need to concern themselves with the implementation details of the modules (e.g., coding process); they only need to call the required module types. Therefore, only a small amount of instantiation and development configuration is required to meet various user needs. It is flexible, simple, and convenient to use, effectively improving the efficiency of engineering project development, reducing hardware storage and management costs both inside and outside the factory, as well as software development and maintenance costs. It enables the rapid acquisition of relay protection and control devices that meet user requirements.

Figure 5As shown, for ease of explanation, only the parts related to this embodiment are shown. For example, this application embodiment provides a terminal device 300, including a processor 301, a memory 302, and a computer program stored in the memory 302 and executable on the processor 301. When the processor 301 executes the computer program, it implements the steps of a management method.
