Abstract
Description
Technical Field
[0001] This invention relates to a panoramic intrinsic monitoring system and method for protection and control devices, belonging to the field of power system protection and control technology. Background Technology
[0002] The safety and reliability of power systems are crucial for the normal operation of modern society. With the large-scale integration of renewable energy and the increase in distributed energy, my country's power supply structure is shifting from being dominated by fossil fuel power generation to providing reliable power support from new energy sources. The system form is changing from the three elements of "source, grid, and load" to the four elements of "source, grid, load, and storage." Multiple new technologies coexist in the power grid, making the operating environment increasingly complex. Protection and control devices are crucial for the safe and stable operation of the power grid, and the requirements for their security and data reliability are becoming increasingly stringent. With the vigorous development of smart substation technology, the types of data interaction between equipment within the substation are becoming increasingly complex, and the data flow is growing rapidly. Integrated circuit components are widely used in secondary equipment, significantly improving the performance of protection and control devices. However, at the same time, problems such as component instability leading to critical data anomalies and single-event upsets caused by high-energy particle bombardment are gradually emerging. These problems have become a major cause of incorrect behavior by protection and control devices, leading to the destruction or tampering of internal data and seriously affecting the safe and stable operation of the power grid.
[0003] Protection and control devices are core equipment for the safe and stable operation of power systems. Their operational status directly determines the reliability of power supply. Hardware failures, FPGA logic anomalies, or CPU software malfunctions can easily lead to malfunctions or failures to operate, potentially triggering power system accidents and causing significant economic losses and adverse social impacts. Therefore, comprehensive, real-time, and endogenous monitoring of protection and control devices is crucial for fault diagnosis and location, and is essential for ensuring the safe operation of power systems, possessing significant engineering application value.
[0004] Currently, the existing intrinsic monitoring systems of protection and control devices differ from actual operation and maintenance needs in several ways: First, the monitoring scope is incomplete, focusing primarily on single-dimensional monitoring (such as monitoring only hardware status or only software operation), failing to achieve panoramic coverage of device hardware, FPGA logic, and CPU software, and making it difficult to capture complex faults caused by multi-dimensional collaboration; second, data acquisition is incomplete, with many errors on the FPGA side simply marked as invalid, without accurate counting and statistics of errors at each stage, resulting in the CPU side receiving only the results and being unable to obtain information on the root causes of faults. Therefore, implementing a monitoring method for protection and control devices that can achieve panoramic intrinsic monitoring and storage of panoramic operational information has become a pressing technical challenge in the field of power system protection and control. Summary of the Invention

[0049] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solution of the present invention, rather than limitations thereof. In the absence of conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.
[0050] Example 1:
[0051] This embodiment introduces a panoramic intrinsic monitoring system for protection and control devices, such as... Figure 1 As shown, it includes:
[0052] The device includes a unified interface module, a data acquisition module, a data fusion module, a panoramic intrinsic monitoring module, and a data storage module. All modules work together through the device's internal bus.
[0053] The unified interface module is used to provide a unified information access interface to obtain the operating data of each plug-in in the protection and control device;
[0054] The data acquisition module is connected to the unified interface module and is used to acquire multi-source operating data of the protection and control device through the unified interface module.
[0055] The data fusion module is connected to the data acquisition module and is used to fuse the multi-source operating data and construct a comprehensive feature vector characterizing the operating status of the protection and control device.
[0056] The panoramic intrinsic monitoring module is connected to the data fusion module and is used to monitor the hardware, logic and software functions of the protection and control device in real time, and issue corresponding alarm signals when abnormalities occur.
[0057] The data storage module is connected to the data acquisition module and the data fusion module, and is used to store operational data.
[0058] The multi-source operational data includes hardware status data of each plug-in in the protection and control device, FPGA logic operation data, bus operation data, and CPU software operation data, providing comprehensive and accurate basic data support for panoramic endogenous monitoring and data fusion.
[0059] The hardware status data is collected through the board-level support package, including voltage monitoring information, chip temperature monitoring information, optical power information, hardware self-test information, memory monitoring information, flash abnormal errors and other hardware monitoring information of this board; at the same time, hardware performance information of this board, such as memory usage rate, CPU usage rate, flash usage rate, task scheduling latency rate, communication latency rate and other hardware performance information of this board, are also collected.
[0060] The FPGA logic operation data focuses on collecting the operating status data of each functional module of the FPGA, including error counts (pulse error statistics, error statistics of each module) at each stage of data input and output. This replaces the existing technology that simply invalidates FPGA errors, providing accurate data support for fault location.
[0061] The bus operation data includes bus monitoring information such as real-time error information for high-speed bus operation, statistical error information for high-speed bus operation, real-time error information for CAN bus operation, statistical error information for CAN bus operation, real-time error information for slow bus operation, and statistical error information for slow bus operation.
[0062] The CPU software operation data includes the CPU-side software operation status, task execution status, and software error information, clearly distinguishing the boundaries between software and hardware errors and avoiding misdiagnosis of faults.
[0063] The results of the data acquisition module are accessed through a unified interface module, which balances scalability and compatibility and strengthens the uniformity of data access methods. The unified interface obtains information fusion from multi-source data through a type + information approach, realizing unified acquisition, transmission and interaction of multi-source data, including the local board with a CPU chip and other non-local boards without CPU chips, to obtain the operating data of each plug-in of the entire device.
[0064] The unified information access interface includes the information access interface for this board and the information access interface for other boards.
[0065] This board's information access interface integrates the board's operational information, including the board-level support package, FPGA, and its own information access requirements. It adopts a general interface design, with the reference interface format as follows: , To fix the address of this board, this interface can uniformly obtain hardware monitoring information, hardware performance information, and bus monitoring information of this board, simplifying the data access process.
[0066] Non-local information access interface: The CPU periodically queries the operating data of remote plug-ins according to a preset cycle, and synchronously transmits the queried real-time data to the data storage module and data fusion module to ensure that the operating status of remote plug-ins can be monitored in real time and the data can be traced in a timely manner. The reference interface format is as follows: , This is the actual address for other boards.
[0067] The data fusion module is used to fuse multi-source operational data from the data acquisition module, employing a combination of data-level fusion and feature-level fusion. This effectively eliminates data redundancy, fills in missing data, and extracts effective operational and fault features, providing high-quality and high-reliability support for panoramic intrinsic monitoring and data storage.
[0068] The data-level fusion normalizes and weights multi-source operational data of the same type (such as error statistics data of different buses and error count data of different modules) to improve data consistency and reliability; the weighted fusion includes weighting and fusing the error count data of each module of the FPGA to highlight the error information of key modules.
[0069] The feature-level fusion extracts the core feature parameters of each type of data (such as hardware temperature threshold, FPGA error rate, CPU utilization threshold, and bus error frequency), fuses multi-dimensional features, and constructs a comprehensive feature vector of the operating status of the protection and control device, thereby achieving a comprehensive characterization of the device's operating status.
[0070] The panoramic endogenous monitoring module includes a hardware panoramic endogenous monitoring submodule, an FPGA logic monitoring submodule, and a CPU software monitoring submodule.
[0071] The hardware panoramic intrinsic monitoring submodule is used to monitor hardware status data and hardware performance data in real time. When hardware parameters (such as chip temperature, voltage, and optical power) exceed preset thresholds or hardware abnormalities occur (hardware self-test failure, flash abnormality, and memory ECC error), a hardware alarm signal is issued. At the same time, it displays performance parameters such as memory usage and CPU usage in real time, promptly identifies hardware performance bottlenecks, and provides early warnings for operation and maintenance.
[0072] The FPGA logic monitoring submodule is used to monitor the operating status and error count data of each module of the FPGA in real time. When the error count exceeds the preset threshold or a bus abnormality occurs (such as bus CRC check error or encoding error), an FPGA logic alarm signal is issued. Through the error count data, the faulty module and fault type on the FPGA side can be accurately located, providing a clear direction for fault diagnosis.
[0073] The CPU software monitoring submodule is used to monitor the running status and task execution of the CPU software in real time, and to issue software alarm signals when software errors, task scheduling delays exceeding limits, or communication delays exceeding limits occur.
[0074] The CPU software monitoring submodule is also used to strictly distinguish between hardware and software errors. Hardware errors are defined as hardware and FPGA-related errors, while software errors are defined as board-level support package and CPU-related errors, which facilitates fault classification and location and improves troubleshooting efficiency.
[0075] The data storage module adopts a dual storage scheme that combines memory storage and text recording;
[0076] The memory storage is used to store short-term real-time running data;
[0077] The text records are used to store long-term operational data in a text format, including all information output by the data fusion module, and support offline text analysis and data traceability.
[0078] The memory storage adopts a cyclic overwrite method, focusing on storing hardware and software error data and distinguishing between hardware and software errors, which facilitates quick retrieval and real-time analysis, and improves the real-time performance of fault location.
[0079] Example 2:
[0080] This embodiment introduces a panoramic endogenous monitoring method for a protection and control device, including:
[0081] Multi-source operational data of protection and control devices are collected through a unified information access interface;
[0082] The multi-source operating data is fused to construct a comprehensive feature vector characterizing the operating status of the protection and control device;
[0083] The hardware, FPGA logic, and CPU software functions of the protection and control device are monitored in real time based on the comprehensive feature vector, and corresponding alarm signals are issued when an anomaly is detected.
[0084] Example 3:
[0085] This embodiment describes the overall operation process of a panoramic endogenous monitoring system for a protection and control device, such as... Figure 2 As shown:
[0086] I. System Initialization
[0087] After the protection and control device is started, each module completes initialization, including device resource configuration, hardware driver, bus driver, data structure creation, memory allocation, file creation, etc., to ensure that the system can run normally.
[0088] II. Data Acquisition and Transmission
[0089] like Figure 3 As shown, through a unified access interface The system performs data reading operations, combining the operating data returned by pinfo with the data from each board. Based on the device's hardware resource configuration, it communicates with each board to obtain operating information. The operating information reading cycle for this board is 10ms, while the reading cycle for other boards is 100ms. It comprehensively collects multi-source data from hardware, FPGA, CPU, and bus, and after preliminary processing, transmits it to the data fusion module.
[0090] III. Data Fusion
[0091] like Figure 4 As shown, multi-source data undergoes data-level and feature-level fusion to eliminate data redundancy, fill in missing data, and extract core features. Data-level fusion primarily involves direct operational errors, including normalized and weighted fusion of multi-source data of the same type (such as execution errors from modules on different buses or execution errors from different logic modules) to improve data consistency and reliability. For example, weighted fusion of error count data from various FPGA modules highlights error information from key modules, improving the identification of fault characteristics; and the direct operational results of each software module. Since the acquisition rates of local and non-local data differ, data alignment is also necessary for subsequent storage and processing. Feature-level fusion mainly extracts core feature parameters of various types of devices or modules (such as hardware temperature, voltage, communication reconnection count, CPU utilization, and bus bit error rate), fusing multi-dimensional features to construct a comprehensive feature vector of the device's operating status. This provides a comprehensive characterization of the device's operating status for comprehensive system status analysis.
[0092] IV. Panoramic Endogenous Surveillance
[0093] The panoramic intrinsic monitoring module, based on the data output from the data fusion module, enables real-time panoramic intrinsic monitoring of the hardware, FPGA logic, and CPU software functions of the protection and control device. It is divided into three functional sub-modules, which work together to ensure that the device's operating status can be fully controlled. Each module displays all relevant information.
[0094] V. Data Storage
[0095] A dual storage scheme of "memory storage + text records" is adopted to balance data access speed and data storage capacity. The memory storage includes all erroneous data after the aforementioned data-level fusion, which is saved in real time and replaced periodically. The text records include all data from both data-level and feature-level fusion, and support both long-term data storage and fast retrieval, meeting the dual needs of real-time analysis and historical tracing.
