[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] In existing technologies, protection and control systems mostly adopt multi-chip solutions such as MCU, DSP, and FPGA in terms of hardware. They also design complex parallel bus based on FPGA to meet the interconnection of various boards and chips in the device. The multi-platform, multi-chip, and parallel port interconnection make the system design modification complex and difficult, and the research and development workload is large.

[0042] Therefore, this application discloses a method for generating a distributed relay protection system, which reduces the difficulty of system implementation, significantly reduces the amount of research and development work, and improves development efficiency.

[0043] See Figure 1 As shown in the embodiments of this application, a method for generating a distributed relay protection system includes:

[0044] S101: Receive configuration instructions for the target relay protection system; the configuration instructions are instructions to configure the functions required to be implemented at each system layer according to business requirements; the system layers include data layer, device layer, protocol layer, and interface layer;

[0045] In this step, the system receives configuration instructions from the user based on business needs, specifying the configuration of the target relay protection system. Specifically, this can be done by configuring each pre-defined system layer, i.e., configuring the functions required for each system layer.

[0046] It should be noted that the distributed relay protection system in this embodiment may specifically include: a data layer, a device layer, a protocol layer, and an interface layer. The data layer is used to handle data input, output, and processing. Supported data types include, but are not limited to, single-byte, integer, floating-point, string, array, and vector data. Supported logical operations include, but are not limited to, addition, subtraction, multiplication, division, AND, OR, NOT, delay, cloning, Fourier transform, vector multiplication, addition, and frequency calculation. The device layer represents the collection of data processing operations. Device types include, but are not limited to, server devices, client devices, sampling devices, logic devices, computing devices, and root devices. Specifically, server devices provide data, client devices consume data, sampling devices provide sampling point data, logic devices and computing devices provide logical calculation services, and the root device has the authority to operate the entire data element. The protocol layer is used to extract and encapsulate data, describing which protocol the current device uses for communication, including but not limited to traditional protocols such as 61850 and 103, or proprietary protocols. The interface layer represents the data transmission channel and describes what physical interface the current device uses, including but not limited to traditional interfaces such as network ports, serial ports, and CAN, or shared memory.

[0047] In this embodiment, the interface layer separates the code from the hardware, thereby achieving hardware independence and improving software portability.

[0048] As a preferred embodiment, the process of receiving configuration instructions for the target relay protection system can be specifically described as follows: receiving the configuration instructions through a visual interface. Specifically, the visual interface can be used to display the system hierarchy stored in a preset relational database and all achievable functions in each system hierarchy; then, the user can receive selection instructions to choose the achievable functions according to their needs, that is, configuration instructions for the functions to be implemented in each system hierarchy.

[0049] It is understood that the embodiments of this application utilize a relational database to store information describing the system layers in advance. Specifically, it can store data elements, logical elements, and computational elements in the data layer, device type information in the device layer, communication protocol types and corresponding protocol parameters in the protocol layer, and physical interface types and corresponding interface parameters in the interface layer. After displaying the above information, users can achieve visual and configurable design for each system layer according to business needs, separating business from code and improving business adaptability.

[0050] In practical implementation, the data elements in the aforementioned data layer can specifically be the general data tables that the current device needs to process, such as remote signaling point tables, telemetry point tables, remote control point tables, and setpoint tables. The aforementioned logic elements can specifically refer to the logical functions that the current device needs to process. Logic types include, but are not limited to, addition, subtraction, multiplication, division, AND, OR, NOT, exponential calculation, trigonometric calculation, comparison operations, multiplexing calculation, absolute value calculation, and delay calculation. The consistent logic type interfaces improve scalability. Specifically, the implementation method for each logic element can be pre-written, so that after obtaining the configuration command, the required logic can be componentized according to the configuration command and the implementation method. The aforementioned computational elements can specifically refer to the computational functions that the current device needs to process. Computational types include, but are not limited to, full-wave Fourier transform, half-wave Fourier transform, real and imaginary part calculation, sequence component calculation, frequency calculation and tracking, and differentiation.

[0051] It should be further explained that, in this embodiment of the application, the aforementioned preset relational database can also be used to store relationships between various logical elements, such as: the output of logical element A is the input of logical element B; relationships between logical elements and computational elements, such as: a logical element can use or modify a data element; relationships between computational elements and data elements; and dependencies between computational elements, such as: computational element A depends on the computation result of computational element B. It is understood that all of the above relationships can be stored using foreign keys in the database.

[0052] S102: Parse the configuration instructions and generate a corresponding configuration file based on the parsed configuration parameters;

[0053] In this step, after obtaining the configuration instructions for the target relay protection system, the configuration instructions are further parsed to obtain the configuration parameters in the configuration instructions, and then the corresponding configuration file is generated based on the above configuration parameters.

[0054] It should be noted that in specific implementations, the aforementioned configuration files can specifically include station control layer configuration files and bay layer configuration files. The station control layer application runs on a Linux system, and its main functions include: parsing system configuration files to complete the initialization of the substation control layer; to implement station control layer services, its data layer includes interlocking, remote control, data synthesis and forwarding, etc.; the equipment layer includes the backend, interlocking devices, recording devices, etc.; the protocol layer includes MMS (Microsoft Media Server Protocol), 103 protocol, custom protocols, etc.; and the interface layer includes shared memory, network ports, serial ports, CAN (Controller Area Network) bus, etc. The bay layer application runs on one or more metal systems, and its program architecture is the same as that of the station control layer, meaning that the two configuration files have the same format, thereby enabling distributed deployment for substation control layer services and bay layer services.

[0055] S103: Load the configuration file to generate the target relay protection system according to the configuration file.

[0056] It is understandable that by loading the above configuration files, the corresponding target relay protection system is generated. If the configuration files include station control layer configuration files and bay layer configuration files, then the above station control layer configuration files and bay layer configuration files can be loaded and parsed respectively to complete the initialization of the substation station control layer and bay layer, and generate the target relay protection system.

[0057] In practical implementation, the target relay protection system may include one or more chips, each of which includes all complete system layers: data layer, device layer, protocol layer, and interface layer. That is, all chips have the same system architecture, allowing identical or different services to be deployed across multiple chips for processing. Compared to traditional technologies that require centralized computation using high-performance chips, this embodiment utilizes multiple distributed chips with identical system architectures to collaboratively process computationally intensive services, significantly improving processing efficiency.

[0058] As can be seen from the above scheme, the distributed relay protection system generation method provided in this application includes: receiving a configuration instruction for a target relay protection system; the configuration instruction is an instruction to configure the functions required to be implemented at each system layer according to business needs; the system layers include a data layer, a device layer, a protocol layer, and an interface layer; parsing the configuration instruction and generating a corresponding configuration file based on the configuration parameters obtained after parsing; loading the configuration file to generate the target relay protection system according to the configuration file. It can be seen that this application pre-defines the system layers based on object-oriented principles, allowing users to issue configuration instructions based on the preset system layers to design the required target relay protection system. This layered design reduces the difficulty of system implementation, significantly reduces R&D workload, improves development efficiency, and is also beneficial to system stability and subsequent maintenance.

[0059] This application discloses a specific method for generating a distributed relay protection system. Compared with the previous embodiment, this embodiment further explains and optimizes the technical solution. Specifically:

[0060] The current relay protection system suffers from a complex hardware structure, with multiple chips and architectures leading to high development and hardware costs. Furthermore, the complex application environment of relay protection necessitates manufacturers designing various boards and supporting programs to meet specific field requirements. This significantly increases the workload of research and development, maintenance difficulty, and expansion challenges, requiring substantial R&D effort.

[0061] To enable distributed business expansion, this application provides a main program for loading business functions, which is not responsible for any actual business operations. The business is described by a database file; specifically, a visual configuration is provided based on the database file. That is, the data, devices, protocols, interfaces, logic, and calculations of a single system are entirely determined by the configuration file. Therefore, this application pre-creates a relational database and provides a visual configuration method based on this relational database.

[0062] It is understandable that the above configuration file describes the following: a general data table that the device needs to process, i.e., data elements, which may specifically include remote signaling point tables, telemetry point tables, remote control point tables, sampling point tables, etc., and supports dynamic expansion. The remote signaling point table describes the various remote signaling processing types supported by the currently configured system, and whether remote signaling anti-jitter processing is supported. The telemetry point table describes the telemetry types supported by the currently configured system, supports floating-point and integer processing, and sets the corresponding coefficients and offsets. The remote control point table sets the remote control operation object, remote control type, remote control timeout, remote control pulse width, interlocking logic, and remote control position of the currently configured system. The sampling point table describes the sampling value coefficients.

[0063] The configuration file may also include the computations and logic that the device needs to process, including: various logical functions required by the current configuration system, i.e., logical elements, whose corresponding parameters include logical type, the relationship between logical elements, the relationship between logical elements and computational elements; and various computational functions required by the current configuration system, i.e. computational elements, whose corresponding parameters include computational element type, the relationship between computational elements and data elements, and the dependency relationship between computational elements.

[0064] The configuration file is also used to describe external or built-in devices, protocols, and interfaces, which can be described by information such as device type, physical interface type, interface layer parameters, protocol type, and protocol parameters.

[0065] This application embodiment is based on object-oriented principles and uses C language to implement all functions, ensuring that the main program can run on various operating systems and even bare metal. The interfaces between layers are clear and unambiguous, and the code is highly reusable. By using a unified hardware platform, hardware and R&D costs are reduced, R&D workload is decreased, and product development speed is increased. Business functions are abstracted and refined into independent, common modules, and corresponding business expansion can be achieved through visual configuration between modules. This increases system flexibility and reduces system dependence on hardware.

[0066] As can be seen from the above, when facing different business needs, the main program of this application embodiment does not need to be modified. Only the data elements, logic elements, computing elements, devices and corresponding protocol interfaces required to support the business need need to be modified using a visual tool. The main program will automatically load the configured business logic to realize the corresponding different business needs and improve the scalability of the function.

[0067] The following describes a distributed relay protection system designed using the distributed relay protection system generation method disclosed in this application, through a specific implementation scenario. (See also...) Figure 2 As shown, specifically:

[0068] Each core of each chip contains a complete data layer, device layer, protocol layer, and interface layer, utilizing Zynq (a scalable processing platform) as its hardware carrier. The shared memory and LVDS (Low-Voltage Differential Signaling) bus of the interface layer enable distributed interaction. The MCU (Microcontroller Unit) board is responsible for central regulation. The shared memory is specifically divided into 16 channels, each 1 Mbyte, further subdivided into 1024 smaller channels, each 1024 bytes. The LVDS bus connects the shared memory of different chips, enabling memory sharing between them. Furthermore, using a serial LVDS bus allows for the introduction of different operating systems to each core based on business requirements or real-time demands. The entire system is flexible and configurable, enabling distributed heterogeneous systems. Relay protection functions can be mapped to different cores of different chips. The data layer and device layer are identical in each core, while the interface layer is highly reused, significantly reducing workload. Simultaneously, the distributed design can flexibly adapt to complex substation operations or high-intensity computations.

[0069] See Figure 3 As shown, relay protection systems should at least have a station control layer data center and a bay layer data center. The station control layer data center is equipped with a heterogeneous Linux operating system, while the bay layer data center is equipped with a real-time operating system, depending on business requirements. If the bay layer is complex, multiple bay layer data centers can be added. Devices within the same data center interact through the data center; these devices can be data producers or data consumers. Devices in different data centers interact through protocols and interfaces. Devices with different chips and cores are ultimately combined to form the relay protection system. This system has highly reusable functions, strong stability, and can be easily extended to adjacent business areas such as power distribution.

[0070] Traditional embedded debugging methods are inefficient and difficult to implement. The embodiments of this application use a distributed architecture and the code achieves hardware independence. Therefore, the debugging code can be deployed on a PC, which facilitates the debugging and maintenance of the code.
