Description

Technical Field

[0001] This invention belongs to the field of substation remote monitoring technology, and particularly relates to a substation monitoring system and remote fault location method based on master-slave station service. Background Technology

[0002] In recent years, unmanned substations and centralized control stations have been continuously built. Most substations have adopted centralized monitoring and unmanned operation mode. Substations have realized remote control and remote adjustment functions through the remote operation and maintenance master station monitoring system and substation monitoring system of automated equipment. The reliability of remote control has an important impact on the safe and reliable operation of the power grid.

[0003] Regarding the remote operation and maintenance master station for automated equipment, the key to ensuring the safe and reliable operation of unattended substations lies in how the on-duty personnel can promptly grasp the substation's operating status based on the information provided by the monitoring system and correctly operate the equipment or handle abnormal situations.

[0004] The substation automation equipment condition monitoring and intelligent diagnostic system adopts a hierarchical architecture, consisting of a master station and station-level systems. The station-level automation equipment condition monitoring and intelligent diagnostic system uniformly collects operational status information from automation equipment such as the station control layer monitoring host and bay layer measurement and control devices, and performs storage, analysis, display, and transmission to the master station. The master station automation equipment condition monitoring and intelligent diagnostic system can be deployed at the dispatch master station or centralized control master station, receiving data from multiple station-level systems to achieve remote monitoring, operation and maintenance management, and other functions for multiple substation automation equipment.

[0005] Currently, data exchange between the dispatching and centralized control master station and the substation communication gateway typically uses the 104 protocol. The 104 protocol is a process-oriented interaction protocol with poor scalability, transmitting remote monitoring, remote control, and remote equipment data through the substation communication gateway's forwarding table. However, remote monitoring of substation equipment status and remote equipment diagnostics require access to substation model files, engineering backup files, and offline historical data. Therefore, the current data exchange method based on the substation communication gateway's forwarding table cannot meet the needs of remote substation operation and maintenance. Summary of the Invention

[0039] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, apparatus, product, or device that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0041] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0042] Example 1

[0043] like Figure 1-2As shown, this embodiment provides a substation monitoring system based on a master-slave station service-oriented interaction mechanism, including a remote operation and maintenance master station for automated equipment and a remote operation and maintenance substation for automated equipment. The remote operation and maintenance substation for automated equipment communicates with the remote operation and maintenance master station for automated equipment and with the inspection equipment of the substation. The remote operation and maintenance substation for automated equipment includes a virtual equipment module, which includes multiple virtual intelligent electronic devices. Each virtual intelligent electronic device corresponds to each intelligent electronic device (IED) in the substation and is used to store the monitoring information of the automated equipment.

[0044] To meet the needs of remote operation and maintenance services for substation automation equipment for accessing various types of substation data, this project adopts a service-oriented master-slave data communication model, enabling the remote operation and maintenance master station of automation equipment to access various types of substation data on demand.

[0045] The master and slave stations communicate via the DL / T860 protocol. To enable communication between the remote operation and maintenance slave station and the remote operation and maintenance master station of the automation equipment, the slave station adopts a proxy communication mode, which maps each intelligent electronic device in the substation to a virtual intelligent electronic device of the slave station. The data models of the virtual intelligent electronic devices and the physical intelligent electronic devices are consistent, and the same virtual access point and server are used. The slave station provides the same network address for all virtual intelligent electronic devices, uses domain-specific objects to access variables and information, and realizes data interaction services with the master station client.

[0046] The file interaction mechanism for remote services mainly includes a list query mechanism, a report triggering mechanism, and a write file query mechanism. These three mechanisms can be used in combination to achieve file interaction between the master and sub-sites.

[0047] Example 2

[0048] like Figure 3 As shown, the present invention also provides a substation inspection method based on a master-slave station service-oriented interaction mechanism. Based on the aforementioned substation monitoring system, the method includes the following steps: the remote maintenance master station for automated equipment configures an inspection strategy and sends it to the remote maintenance substation for automated equipment; the remote maintenance substation for automated equipment parses the inspection strategy and sends an inspection command to the inspection equipment; the inspection equipment performs an inspection on the automated equipment according to the inspection command, generates an inspection result file after the inspection is completed, and sends it to the remote maintenance master station for automated equipment; the remote maintenance master station for automated equipment parses the inspection result file.

[0049] With the comprehensive advancement of smart grid construction and the large-scale commissioning of smart substations, as well as the widespread application of unmanned substations, the logic and configuration of intelligent substation automation equipment are more complex than traditional substation equipment, leading to a sharp increase in maintenance workload and difficulty. Under the traditional substation's periodic manual maintenance model, the rich equipment operating status information provided by intelligent substation automation equipment is not being prioritized for utilization. Monitoring the status of automated equipment relies on on-site inspections by maintenance personnel, resulting in slow response times to accidents and defects. With the widespread adoption of unmanned substation models, there is an urgent need for remote maintenance methods such as remote status monitoring and remote automatic inspection of substation automation equipment to reduce the heavy maintenance workload of substations.

[0050] The automated remote inspection process is based on service-oriented master-slave data interaction technology. It develops remote inspection services for slave stations, enabling the master station to check the operating status and various operating parameters of substation automation equipment, thereby improving inspection efficiency and reducing the number of on-site manual inspections.

[0051] The master station configures the inspection strategy using the inspection strategy configuration tool and sends a start inspection command to the substation via the DL / T860 file writing service. Upon receiving the inspection strategy file, the substation parses it, starts the inspection, and the automated equipment inspection module inspects the automated equipment according to the inspection equipment, sequence, and content specified in the inspection strategy file. After all inspections are completed, an inspection result file is generated based on the inspection results. The master station is notified of the inspection result file generation via the DL / T860 report service. Upon receiving the report, the master station reads the automated equipment inspection result file using the message reading service. The master station then parses the inspection result file and automatically displays it in a visual format.

[0052] The main site provides a visual interface for configuring automated equipment inspection strategies. The inspection strategy includes: the equipment to be inspected, the inspection order, and the inspection content for each device. The inspection strategy is saved as an XML file.

[0053] The patrol strategy can be configured as follows:

[0054] <?xml version="1.0" encoding="UTF-8"?>

"yyyyMMddhhmmss" represents the inspection time (year, month, day, hour, minute, second). The year is a 4-digit number, and the month, day, hour, minute, and second are all 2-digit numbers.

[0102] Example 3

[0103] like Figure 4-5 As shown, the present invention also provides a substation monitoring system based on a master-slave station service-oriented interaction mechanism, including the aforementioned substation monitoring system, substation communication gateway, and measurement and control device. The remote operation and maintenance master station for the automated equipment of the substation monitoring system further includes a message interaction module; the substation communication gateway includes a message interaction module and a remote control command processing module, and the substation communication gateway communicates with the message interaction module of the remote operation and maintenance master station for the automated equipment through its own message interaction module; the measurement and control device includes a message interaction module and a remote control command processing module, and the measurement and control device communicates with the message interaction module of the substation communication gateway through its own message interaction module.

[0104] Each layer's message interaction module and remote control command processing module is equipped with observation points, which are used to generate remote control operation process log files.

[0105] In automated equipment remote maintenance, remote control operations are performed from the main station. The main station sends remote control commands to the substation communication gateway, which in turn sends them to the monitoring and control device. The monitoring and control device then sends the commands to the smart terminal, which in turn sends them to the operating mechanism. When an anomaly occurs during remote control operations from the main station, the existing solution involves capturing the remote control command messages between the main station and the smart terminal and analyzing them step by step. This requires a high level of expertise from the analysts, takes a considerable amount of time, and results in low efficiency in fault location.

[0106] The secondary equipment of the intelligent substation provides a wealth of self-test and operation status monitoring information, mainly including the internal operating voltage, CPU temperature, optical port light intensity, optical port power, link status, etc. This information mainly characterizes the internal operating status of the secondary equipment. However, this data does not include the internal logic processing process of the device. If a problem occurs during the various logic processing processes of the data within the device, the operation and maintenance personnel cannot locate it. The manufacturer's developers must conduct on-site debugging to determine the problem.

[0107] This embodiment establishes observation points on each node device involved in the issuance and execution of remote control commands. Each observation point records the internal remote control command logic processing of that device, and this record is stored in a file. If a remote control failure occurs, the central control station retrieves the files from all observation points via file access and automatically analyzes them layer by layer to pinpoint the fault. This method generates its own internal remote control processing log for each node device through which the remote control command passes, eliminating the need for third-party message capture and analysis tools and requiring operators to analyze complex message interactions. This results in short fault location time and high efficiency.

[0108] The master station deploys a control operation module, a remote control fault analysis module, and a message interaction module with the next-level equipment. The remote control fault analysis module collects remote control operation log files generated by each node device from the master station to the monitoring and control unit, analyzes the records from each node, locates the fault point, and displays the results graphically to the user. The message interaction module with the next-level equipment uses DL / T 860 messages to send remote control command messages to the substation and receives remote control result messages; it also sends remote control log file retrieval commands and receives remote control operation log files. The message interaction module with the next-level equipment is responsible for establishing observation points, i.e., writing remote control operation log files according to the specified format after the remote control message is sent and upon receiving the remote control result return message.

[0109] The substation communication gateway is equipped with a message exchange module for communication with the upper-level equipment, a remote control command processing module, and a message exchange module for communication with the lower-level equipment. The upper-level equipment message exchange module receives remote control command messages from the master station, sends remote control result messages and remote control operation log files to the master station, and receives remote control operation log file retrieval commands from the master station, sending the remote control operation log files to the master station. The remote control command processing module is responsible for parsing remote control commands, performing error-prevention logic calculations, and determining whether remote control operations can be executed based on the calculation results. The lower-level equipment message exchange module sends remote control command messages to the monitoring and control device, receives remote control result messages from the monitoring and control device, sends remote control operation log file retrieval messages to the monitoring and control device, and receives the remote control operation log files from the monitoring and control device. The lower-level equipment message exchange module communicates with the monitoring and control device via DL / T 860 messages.

[0110] The monitoring and control device is equipped with a message exchange module for communication with the upper-level equipment, a remote control command processing module, and a message exchange module for communication with the lower-level equipment. The upper-level communication module receives remote control command messages from the substation communication gateway and sends remote control command result messages to the substation communication gateway. The remote control command processing module is responsible for parsing remote control commands, calculating anti-misoperation interlocking logic, and determining whether to issue a remote control command based on the calculation results. The lower-level communication module sends control messages to the process-level intelligent terminal and receives control result messages from the intelligent terminal.

[0111] Observation points are established at each node along the path of the remote control command. As the command passes through each observation point, the corresponding module records the remote control command processing information according to a prescribed format, generating a remote control operation log file.

[0112] When a remote control command is sent down: After each observation point receives a remote control command, it records the received remote control point parameters, the time of receipt, the remote control target value, and the result processed by this module, including whether the interlocking logic meets the conditions, whether the concurrent control is met, whether the communication status is normal, whether the remote control point is valid, the position status verification result, and whether the module successfully sends the command to the next processing logic.

[0113] When the remote control command returns: After each observation point receives the return result of the remote control command, it records the remote control parameters received by the observation point, the time of receipt, the remote control result, and whether this module successfully returned the result to the upper layer processing logic.

[0114] Example 4

[0115] This invention also provides a substation remote control fault location method based on a master-slave station service-oriented interaction mechanism. Based on the aforementioned substation monitoring system, the method includes the following steps: the remote maintenance master station for automation equipment sends a command to the substation communication gateway to request the remote control operation process log file; upon receiving the command, the communication gateway requests and stores the remote control processing log file from the monitoring and control device; the remote maintenance master station for automation equipment reads the remote control processing log files from the communication gateway and the monitoring and control device; and the remote maintenance master station for automation equipment analyzes all the remote control processing log files to locate the remote control fault location.

[0116] When the master station receives a remote control fault, clicking "Remote Control Fault Location" on the remote control interface will automatically initiate the remote control fault location logic. The process is as follows:

[0117] The master station remote control fault analysis module requests the remote control processing log file from the substation communication gateway through the DL / T 860 file read service;

[0118] After receiving the data, the substation communication gateway device retrieves the remote control processing log file from the monitoring and control unit.

[0119] The substation communication gateway places its own remote control processing log files and the log files of the measurement and control device into a fixed directory;

[0120] The substation communication gateway notifies the master station that the remote control process log file is ready in the form of DL / T860 reporting service;

[0121] The master station received the notification and read the remote control process log files of the measurement and control device and the substation communication gateway in the form of DL / T860 message;

[0122] The master station remote control fault analysis module integrates the master station log files, substation communication gateway log files, and measurement and control device log files to analyze the processing results of remote control commands at each observation point, determine the fault location, and visualize the fault node in a graphical manner.
