Description

Technical Field

[0001] The present invention relates to the field of power system automation technology, and in particular to a high-voltage direct current protection constant value cloud-edge collaborative management system, method and medium. Background Art

[0002] In HVDC transmission control and protection systems, DC protection settings are core parameters for ensuring the safe and stable operation of power equipment. Their accuracy and real-time performance are directly related to the accuracy of key operation and maintenance services such as grid fault diagnosis and status assessment. In actual operation, DC protection setting management involves the coordinated operation of multiple converter stations and multiple types of protection devices, and needs to adapt to complex and changing operating environments. However, traditional setting management methods have exposed many defects in the actual operation and maintenance scenarios of HVDC transmission systems, making it difficult to meet the modern power grid's requirements for safety, real-time performance, and intelligence.

[0003] In HVDC transmission scenarios, protection settings need to be dynamically adjusted according to the grid's operating status. For example, when the load at a converter station suddenly increases or the ambient temperature changes drastically, the protection device settings need to be updated promptly to match the new operating conditions. However, traditional setting updates rely on manual on-site operations or offline modifications. This manual intervention method results in the inability to synchronize setting updates to the cloud and various edge devices in a timely manner, causing inconsistencies between the operation and maintenance system and the protection device settings, leading to misjudgments in the protection logic. For example, due to a delay in setting updates at a converter station, the protection device failed to operate in time when a short-circuit fault occurred, ultimately causing equipment damage.

[0004] The high-voltage direct current transmission network covers multiple converter stations, and the settings of the protection devices at each station must remain consistent globally. However, traditional setting management lacks a unified comparison and analysis mechanism across sites. For example, in a regional power grid, different converter stations have different setting settings for the same type of protection device, resulting in some devices malfunctioning during regional faults, while other devices do not respond, ultimately expanding the scope of the fault. In addition, the current setting transmission mainly relies on the local network and does not fully combine the cloud-edge collaborative architecture to achieve distributed verification and disaster recovery backup, which makes the setting data at risk of tampering during transmission. Once the local network fails, the setting data is easily lost and there is a lack of effective recovery methods.

[0005] In summary, the traditional DC protection setting management method has many problems and is difficult to meet the needs of HVDC transmission systems for safe and efficient operation and maintenance. Therefore, there is an urgent need for a setting management technology based on a cloud-edge collaborative architecture to improve the safety and efficiency of power grid operation and maintenance.

[0062] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings. The embodiments are provided for illustrative purposes only and are not to be construed as limiting the present invention. The accompanying drawings are provided for reference and illustration only and do not constitute a limitation on the scope of protection of the present invention. Many changes may be made to the present invention without departing from the spirit and scope of the present invention.

[0063] Traditional converter station setting management technology relies on manual on-site operation or offline modification, resulting in significant delays in customized updates of multiple converter stations. It also lacks a unified coordination mechanism, making it difficult to achieve multi-station collaborative optimization. Furthermore, traditional solutions mostly use a single-core processing mode at the hardware architecture level, resulting in low inter-core communication efficiency and inability to meet the real-time requirements of large-scale power systems. To address the above issues, reference Figure 1 The embodiment of the present invention provides a cloud-edge collaborative management system for HVDC protection settings, which achieves remote second-level synchronization through the Transmission Control Protocol / Internet Protocol (TCP / IP) and combines the task distribution and inter-core interrupt mechanism of the multi-core central processing unit (CPU) to ensure the real-time collaborative update of the settings of multiple converter stations. Figure 1 As shown, the system includes an operation control module 101 , a control and protection module 102 , a field measurement module 103 and an edge protection device 104 .

[0064] In the specific implementation process, Figure 2 As shown in the figure, after the engineer modifies the fixed value parameters or enters new parameters in the Engineer Workstation (EWS), the system establishes a connection with the fixed value management CPU of the protection host through the local area network (LAN), and completes the data transmission according to the three-step handshake protocol of the fixed value length message, the fixed value data message and the execution command message to ensure the integrity of data transmission. After the fixed value management CPU receives the complete message, it generates three backup files: current, redundant and historical in the local file system, and writes the new parameters into the shared memory area of the master core. The shared memory area is connected to each slave core through the peripheral component interconnect express bus (PCIE). The master core triggers the message interrupt signal (MSI) SignaledInterrupt) drives each slave core to synchronously read the new set value from the shared memory area and update its own local storage. After the update of each core is completed, the protection host sends the updated set value to the control device and measurement and control device through the communication board or interface board, and completes the update of the equipment protection logic through the actuators such as circuit breakers or disconnectors. In terms of system architecture, the operation control module builds a cloud-based unified management platform to support parameter input, verification and structured message generation; the control and protection module deploys the set value management central processor to undertake communication analysis and inter-core distribution tasks; the field measurement module collects real-time data through sensors and other equipment, and uploads it to the protection host through the measurement and control device. The high-voltage DC protection set value cloud-edge collaborative management system realizes zero-delay distribution of data between cores through shared memory, and cooperates with PCIE bus and MSI interrupt technology to realize efficient collaborative control from the cloud to the edge, ensuring instantaneous synchronization of set value updates between multiple cores, and to a certain extent solves the technical bottlenecks of traditional solutions in terms of collaboration and real-time performance.

[0065] In some embodiments, the operation control module includes a cloud-based constant value management platform, which is used to respond to the converter station protection constant value adjustment signal, verify the input converter station protection constant value adjustment data according to a preset value range, generate a structured constant value message sequence, and send the structured constant value message sequence to the control protection module through a three-step handshake protocol.

[0066] Specifically, the operation control module is used to coordinate the constant value management of multiple converter stations. The operation control module builds a unified cloud constant value management platform, engineer workstation (EWS, Engineer Work Station), monitoring workstation (OWS, Operator Work Station) and background workstation in the cloud. Among them, the engineer workstation is used to enter, modify and update the constant value parameters. The monitoring workstation is used to monitor the system operation status and constant value parameters in real time. The background workstation is used to run the VIGET application (VIGET Application), which is responsible for data analysis and logic control. The power system engineering personnel input or modify the protection constant value parameters of each converter station (such as the differential protection fast-break constant value or the overcurrent protection delay time, etc.) through the engineer workstation, triggering the generation of the converter station protection constant value adjustment signal, and uploading the converter station protection constant value adjustment signal to the cloud constant value management platform. After receiving the converter station protection constant value adjustment signal, the cloud constant value management platform performs upper and lower limit verification on the new constant value parameter entered by the engineer based on the preset safety range to ensure that the parameter value is within a reasonable upper and lower limit range. If If the new set value parameter exceeds the upper and lower limits of the allowed set value, an alarm will be triggered and execution will be refused to prevent unreasonable parameters from affecting the safe operation of power equipment. On the contrary, if the new set value parameter is within the upper and lower limits of the allowed set value, it is determined that the verification has passed. The cloud-based set value management platform will convert the set value parameter into a structured set value message sequence, and establish a secure communication link through the transmission control protocol / Internet protocol. Using the three-step handshake protocol of the fixed length message, the fixed value data message and the execution command message, the structured set value message sequence will be sent to the protection device of the control and protection module to ensure the integrity and reliability of data transmission.

[0067] It should be noted that if Figure 3As shown, after the engineer enters the new fixed value parameters at the engineer workstation, the system generates a fixed value length message (including the total length information of the fixed value data) and sends it to the protection host through the Ethernet interface. After the protection host receives the message, it will save the fixed value length information and immediately reply with a success or failure message to inform the engineer station whether the length information is successfully received. After the engineer workstation receives the successful reply of the protection host to the fixed value length message, the engineer workstation packages the fixed value parameters into a fixed value data message according to the protocol format and sends it to the protection host through Ethernet. After receiving it, the protection host saves the fixed value data and replies with a success or failure message again to confirm whether the data is saved correctly. The engineer workstation then sends a fixed value call message to the protection host. After receiving the call request, the protection host organizes the fixed value data stored locally, generates a fixed value data return message, and sends the fixed value data return message through the send buffer (Send The protection host sends the fixed value data packet back to the engineer workstation. After receiving the fixed value data packet from the protection host, the engineer workstation verifies the fixed value called back to verify the accuracy and consistency of the data. After the verification is completed, the engineer workstation sends a reply message to the protection host to inform the success or failure of the verification. At this point, a complete fixed value interaction process is completed.

[0068] In some embodiments, the control and protection module is used to parse the received structured fixed value message sequence to obtain the latest valid fixed value, and trigger the multi-core collaboration mechanism to perform a fixed value instantaneous update synchronization operation on multiple converter stations in the high-voltage direct current transmission system through the latest valid fixed value to obtain the updated fixed value of the converter station. In this embodiment, the control and protection module includes a protection host, a measurement and control device, and a converter station control device. The protection host is equipped with a multi-core central processing unit (CPU), a fixed value management central processing unit, a peripheral component interconnect high-speed bus (PCIE, Peripheral Component Interconnect Express) and a communication interface board, the communication interface board includes a communication board and an interface board, the communication board is connected to the multi-core central processing unit through a peripheral component interconnection high-speed bus to achieve inter-core data sharing; the interface board is directly connected to the field layer equipment through a cable; the multi-core central processing unit includes a master core CPU2 and multiple slave cores CPU3, wherein the master core is used for fixed value management, message parsing and inter-core coordination, and the slave core is used to execute specific protection algorithms and logical operations. The master core of the multi-core central processing unit is connected to each slave core through a peripheral component interconnection high-speed bus. The functions of each module of the control protection module are specifically as follows:

[0069] The fixed value management central processor is used to receive a structured fixed value message sequence from the cloud fixed value management platform, parse the structured fixed value message sequence to obtain the latest valid fixed value, and synchronously write the latest valid fixed value into the fixed value triple backup file system and the peripheral shared memory space through the peripheral component interconnect high-speed bus;

[0070] The master core is used to generate a memory write request when writing the latest valid constant value into the peripheral shared memory space, and trigger the generation of an inter-core interrupt signal according to the memory write request, so that each of the slave cores reads the latest valid constant value from the peripheral shared memory space according to the inter-core interrupt signal, and instantaneously update and synchronize the constant values of multiple converter stations in the high-voltage direct current transmission system through the latest valid constant value read by each slave core to obtain the updated constant value of the converter station.

[0071] The communication interface board is used to distribute the converter station updated set value to the converter station control device and the measurement and control device, so that the converter station control device drives the primary equipment to perform protection actions according to the converter station updated set value to cut off the high-voltage direct current transmission line fault.

[0072] Specifically, such as Figure 4 、 Figure 5As shown, the fixed value management central processor receives a structured fixed value message sequence from the cloud through an Ethernet interface and a transmission control protocol / internet protocol, parses the structured fixed value message sequence, parses out a fixed value parameter table, extracts key parameters of the fixed value parameter table, obtains the latest valid fixed value, and performs a cyclic redundancy check (CRC) and a hash-based message authentication code (HMAC) double check on the latest valid fixed value to effectively prevent middleman attacks and message tampering. After the check passes, this embodiment writes the parsed latest valid fixed value into the shared memory area of the device temporary storage area (DDR, Dynamic Random Access Memory), and then triggers a file write task to persistently store the fixed value in the form of three copies (current, redundant, and historical) to the local file system of the flash memory (FLASH). At the same time, the main core writes the latest valid fixed value in batches to the peripheral component interconnect high-speed bus (PCIE, Peripheral Component Interconnect The peripheral shared memory space is a shared memory space for peripherals connected to the CPU Express. The shared memory space adopts a physically continuous allocation method, allocates physically continuous memory through the peripheral component interconnect high-speed bus, and maps it to the same virtual address space of the master core and all the slave cores. Specifically, through address mapping, the master core (CORE0) and all the slave cores (CORE1 to COREn) access the same virtual address space to achieve zero-copy data sharing. In this embodiment, the peripheral shared memory space includes multiple shared memory blocks, each of which corresponds to a fixed value storage space of the slave core.

[0073] In terms of synchronous update and inter-core communication, in order to ensure that each core in the system maintains constant value consistency, the master core (CORE0) writes the updated constant value to the multi-core shared memory, and then notifies other slave cores (CORE1~COREn) to update the relevant constant value through the inter-core interrupt mechanism. After receiving the interrupt signal, all cores will immediately update the local storage and synchronously update the constant value, so that all cores of the entire protection device can synchronously update the constant value within seconds, ensuring the efficiency and consistency of the system. Specifically, after the master core completes the shared memory write, it immediately executes the write memory barrier to ensure that all write operations are visible to other cores. After the write is completed, the master core sends an inter-core interrupt signal (MSI, Message Block) to each slave core through the peripheral component interconnect high-speed bus. The inter-core interrupt signal carries a constant value update flag and a shared memory address pointer. The constant value update flag and the shared memory address pointer can indicate the constant value location that the slave core needs to read. After receiving the inter-core interrupt signal, the slave core executes a read memory barrier to ensure that it can read the updated shared area data. Then the slave core reads the constant values in batches from the shared memory and updates the local storage. The slave core updates its own operating parameters and control logic based on the parsed constant value information to ensure that each core is based on the latest constant value setting when executing tasks. After completing the update, each slave core feedbacks the status to the master core and sends a synchronization completion signal if successful. If an error occurs during reading or verification, it is immediately reported to the master core to trigger automatic rollback or retry. After the master core summarizes the status of all slave cores, it uniformly reports the constant value update completion status of the entire device. This embodiment uses the peripheral component interconnect high-speed bus and multi-core collaboration to achieve multi-core constant value synchronous update in seconds, which significantly improves efficiency compared to traditional single-core serial processing.

[0074] It should be noted that during the constant value file saving process, the system will perform redundant reading operations to ensure the integrity and reliability of the constant value file. If a constant value reading error or update failure occurs, the system can restore the constant value by reading redundant files or old version constant value files to ensure stable operation of the system.

[0075] In some embodiments, the field measurement module is used to collect edge device action status data of the edge protection device in the high-voltage direct current transmission system through a voltage transformer (TV), a current transformer (TA) and an optical current sensor (OCT), and upload the edge device action status data to the measurement and control device of the control and protection module, so that the measurement and control device can perform fixed value update effectiveness verification on the updated fixed value of the converter station according to the edge device action status data, and when the fixed value update effectiveness verification is passed, generate a fixed value update effectiveness report and feed it back to the operation control module.

[0076] In some embodiments, the HVDC protection constant value cloud-edge collaborative management system further includes a constant value comparison and analysis system, and the functions of the constant value comparison and analysis system are specifically as follows:

[0077] Real-time collection of current setting data of the same type of edge protection devices deployed at each converter station and current converter station environmental parameters;

[0078] Based on the current set value data of the same type of edge terminal protection device in different converter stations, the set value mean and set value standard deviation are calculated;

[0079] Performing a horizontal fixed value analysis of multiple converter stations based on the fixed value mean and the fixed value standard deviation; when it is detected that the fixed value mean and the fixed value standard deviation of the edge end protection device exceed a preset value difference threshold, marking the corresponding edge end protection device as a potential abnormality and generating a horizontal comparison alarm log;

[0080] Establishing a correlation model between the fixed value and the environmental parameter based on the historical fixed value data and the historical environmental parameters, and using the correlation model to predict and obtain theoretical fixed value data based on the current converter station environmental parameters;

[0081] Comparing the theoretical fixed value data with the current fixed value data to obtain a fixed value error, and when the fixed value error is greater than a preset error threshold, determining that the corresponding edge end protection device has an environmental adaptability abnormality;

[0082] The fixed value deviation is calculated based on the current fixed value data and historical fixed value data of the edge end protection device of the same converter station in the high-voltage direct current transmission system, and when the fixed value deviation exceeds the preset value difference range, an abnormal deviation alarm signal is triggered.

[0083] Specifically, this embodiment regularly collects the current set value data of the edge protection device from each converter station, and transmits it to the cloud database through the transmission control protocol / internet protocol. The cloud database can realize horizontal comparative analysis of the set values of the edge protection devices of the same model in each converter station. Specifically, the changes in the device set values can be compared according to the preset threshold value. If it is found that the set value of a certain site deviates from the normal working range, or the setting difference with other sites is too large, the system will automatically generate an alarm message. For example, when the set value of a certain device is too high or too low, it means that the working environment of the equipment has changed or there is an error in the set value setting. At this time, the system will immediately issue an alarm. At the same time, the cloud database can identify abnormal set values based on the preset safety range. When the system detects that the set value is abnormal, it automatically generates an early warning message and notifies the power operation and maintenance personnel. After receiving the alarm, the power operation and maintenance personnel can contact the engineer The workstation enters the relevant site to view the specific settings and historical changes of the constants. By obtaining real-time equipment status and constant information, operation and maintenance personnel can quickly locate the problem and reduce the risk of failure. In addition, the cloud database can also combine the temperature, humidity, load and other environmental parameters of each converter station to perform environmental adaptability analysis and other functions. Given that the optimal constant settings of equipment in different environments may be different, this embodiment uses horizontal comparative analysis. The system can more accurately identify unsuitable constants, thereby preventing equipment failures caused by environmental changes. At the same time, operation and maintenance personnel can use historical data analysis to find out the change rules of the equipment's constants under different environmental conditions, providing a scientific basis for future constant adjustment. This intelligent analysis and early warning function greatly improves the operation and maintenance efficiency of the power grid and reduces safety risks caused by human factors or improper equipment settings.

[0084] In some embodiments, the high-voltage direct current protection constant value cloud-edge collaborative management system also includes a safety disaster recovery module, which includes a constant value triple backup file system and blockchain log evidence; in this embodiment, the constant value triple backup file system is used to store the current constant value file, redundant constant value file and old version constant value file, and automatically rolls back to the old version constant value file when an abnormality occurs in the constant value triple backup file system, wherein the constant value update effectiveness verification includes checking the correctness of the constant value loading status and verifying the expected matching of the protection action execution of the edge protection device; the blockchain log evidence is used to record the constant value operation log.

[0085] This embodiment effectively improves the intelligence level of constant value management through system redundancy and fault-tolerant mechanisms, enabling operation and maintenance personnel to promptly discover potential abnormal constant values and avoid power equipment failures caused by constant value errors, thereby ensuring the safe and stable operation of the power system. In the entire constant value update process, this embodiment adopts a triple backup storage strategy to save all constant value files as the current version, redundant version and historical version respectively. When a system abnormality or update failure is detected, the system automatically triggers the rollback mechanism and restores to the historical stable version to ensure that the constant value information is not lost and the system quickly resumes normal operation. This mechanism effectively solves the delay and error problems existing in traditional manual operations, realizes the rapid and accurate remote update of DC core constant value parameters, and greatly improves the safety and reliability of power grid operation.

[0086] In summary, in view of the defects of DC transmission system protection setting value management such as low efficiency of manual on-site review leading to mismatch of cloud and edge setting value versions, inability of core processing architecture to meet the collaborative update needs of large-scale converter stations, and lack of historical tracing and horizontal comparison capabilities leading to difficulty in early warning of hidden risks, the cloud-edge collaborative setting value management system proposed in this embodiment adopts HCM5000 control and protection host as hardware platform. The HCM5000 control and protection host uses multi-core central processing unit collaborative processing and PCIE high-speed bus architecture, combined with transmission control protocol or Internet protocol to build cloud-edge communication channel, realize real-time synchronization of protection device setting value and operation and maintenance system, ensure data consistency, and use the shared memory mechanism and Inter-core interrupt technology enables parallel processing and data synchronization of multi-core central processing units, greatly improving the efficiency of constant value updates. In addition, this embodiment integrates historical data comparison and multi-site horizontal analysis functions, which can automatically identify constant value anomalies and generate risk warnings, providing data support for power grid operation and maintenance decisions. Therefore, this embodiment not only achieves second-level synchronization of constant value parameters through the cloud-edge collaborative architecture, significantly improving the system's real-time performance and data accuracy, but also adopts multi-core collaborative processing and redundant backup mechanisms to enhance the system's fault tolerance and operational reliability. In addition, this embodiment effectively reduces the power grid operation risks caused by improper constant value settings through intelligent analysis functions, providing reliable technical guarantees for the safe and stable operation of the DC protection system.
