[0002] Substations, as hub facilities in the power system, integrate power transformation, distribution, and transmission, and are crucial infrastructure for the system. Their core function is not only to convert power between different voltage levels (stepping down power from the ultra-high voltage transmission system to a safe voltage for users), but also to undertake important tasks such as regional power dispatching, power flow control, and reactive power compensation. The stable operation of substations is directly related to industrial automation production, the operation of urban lifeline systems, and the energy security foundation of modern social and economic operations.

[0003] Traditional substation routine inspections and maintenance rely primarily on manual labor, using fixed monitoring and detection equipment and manual intervention detection equipment for inspection and fault diagnosis. Traditional substation inspection and maintenance methods suffer from the following issues: 1. The inspection workload is high and efficiency is low; 2. Personnel have varying technical capabilities, and subjective initiative impacts the accuracy and effectiveness of monitoring data; 3. During inspections, personnel have poor awareness of the on-site environment.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The following description of some of the technologies involved in the embodiments of this application is provided to facilitate understanding and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of this application. Similarly, for the sake of clarity and conciseness, some descriptions of well-known functions and structures are omitted from the following description.

[0020] Figure 1 This is a structural diagram of a centralized control operation and maintenance system for a substation provided in an embodiment of the present application, including a central management module, and a substation intelligent patrol module, a high-voltage cable fault warning module, an electrical monitoring module, a fault recording module and an electrical error prevention module that are communicatively connected to the central management module, and the substation intelligent patrol module is communicatively connected to the electrical error prevention module, as follows.

[0021] In an embodiment of the present application, the central management module is configured to: analyze and integrate the received data, generate scheduling instructions based on the analysis and integration results, and distribute the scheduling instructions to the corresponding modules.

[0022] Specifically, the central management module receives inspection data from the dual-view infrared temperature measurement pan / tilt in the substation intelligent inspection module, the operating environment and equipment status of each substation device captured by a spherical camera, the sulfur hexafluoride gas status of substation equipment collected by the SF6 detection unit, and the dissolved gas content in the transformer oil collected by the transformer oil online chromatography analysis unit. The central management module also receives high-voltage cable temperature data collected by the cable temperature monitoring unit in the high-voltage cable fault warning module, the sheath current collected by the cable sheath current monitoring unit, the operating environment of the high-voltage cable collected by the cable video monitoring unit, and the partial discharge values ​​of the high-voltage cable acquired in real time by the cable online partial discharge monitoring unit. The central management module also receives power system operating data collected by the monitoring server in the electrical monitoring module. It also receives the changing waveform and target waveform from the fault recording working unit in the fault recording module. It also receives operation logs from the anti-error workstation unit in the electrical anti-error module, as well as monitoring data captured by the remote viewing working unit.

[0023] After receiving this data, the central management module first cleans it, removing low-quality data (such as low-resolution images). The corresponding data is then stored in the database, keyed by the acquisition time. Furthermore, based on the device-related data (such as the operating environment and device status of each substation device captured by a spherical camera, the sulfur hexafluoride gas status of substation equipment collected by the SF6 detection unit, and the dissolved gas content in transformer oil collected by the transformer oil chromatogram online analysis unit), a lifecycle tree for the corresponding device is established. Faults are used as nodes, and each node is bound to the database based on the time of fault occurrence. By browsing the device lifecycle tree, staff can clearly understand the device's fault history and estimate its health status and service life. By clicking on a node in the lifecycle tree, they can access the database to learn the specific details of the fault, significantly reducing search cycles. The central management module can also assess the device's health based on the lifecycle tree and corresponding data in the database.

[0024] On the other hand, the central management module can analyze and integrate the received data to generate corresponding dispatch instructions and distribute them to the corresponding modules. For example, if the central management module finds that the temperature data of the high-voltage cable has been approaching the set threshold for a long time (such as 10 minutes), but has not yet reached the alarm threshold, but the temperature remains high, the central management module will send a dispatch instruction to the substation intelligent inspection module, dispatching the inspection robot to the ground in the persistently high temperature area to conduct an inspection to determine whether abnormal ground conditions are causing the high temperature of the high-voltage cable for a long time.

[0025] In this embodiment of the present application, the substation intelligent inspection module is configured to: plan inspection routes for inspection robots, acquire inspection data from the inspection robots, and transmit this data to the central management module. Inspections are conducted in target areas in response to the central management module's dispatch instructions. The module also monitors the operating environment, equipment status, and gas information of each device in the substation and transmits this information to the central management module. This gas information includes the gas state and dissolved gas content of sulfur hexafluoride.

[0026] like Figure 2 As shown in the figure, the substation intelligent inspection module includes an inspection host, an inspection robot connected to the inspection host, an inspection switch, a dual-view infrared temperature measurement pan / tilt head, a spherical camera, an intelligent lighting controller, an SF6 detection unit, and a transformer oil chromatography online analysis unit.

[0027] Specifically, the inspection host is used to access and visualize data from the dual-view infrared temperature measurement platform, spherical camera, SF6 detection unit, and transformer oil chromatogram online analysis unit. The displayed data is transmitted or filtered in response to user operations. The host receives inspection tasks from the central management module, plans inspection routes based on the tasks, and transmits these routes to the inspection robot. An alarm is generated when the sulfur hexafluoride concentration in the received sulfur hexafluoride gas state exceeds a set safety threshold. An alarm is also generated when the received dissolved gas content exceeds a preset threshold. The inspection switch is communicatively connected to the central management module and transmits data from the dual-view infrared temperature measurement platform, spherical camera, SF6 detection unit, and transformer oil chromatogram online analysis unit to the central management module. The inspection robot is equipped with a dual-view infrared temperature measurement platform and an intelligent lighting controller. It conducts inspections according to the received inspection routes, collects inspection data in real time using the dual-view infrared temperature measurement platform, and transmits this data to the inspection host. This inspection data includes both infrared and visible light images. A dual-view infrared temperature measurement pan / tilt head is used to capture real-time infrared and visible light images of each device in the substation to monitor its temperature and operating status. Spherical cameras are distributed at monitoring points throughout the substation. They utilize zoom, focus, and aperture adjustment functions to meet monitoring needs in different scenarios. They monitor the operating environment and status of each device in the substation in real time and transmit the captured data to the inspection host. An intelligent lighting controller senses ambient light and adjusts lighting brightness and color temperature accordingly. The SF6 detection unit communicates with multiple sensors installed throughout the substation to collect sulfur hexafluoride gas levels from equipment within the substation and transmits these levels and alarm information to the inspection host. The transformer oil chromatogram online analysis unit monitors the dissolved gas content in transformer oil and transmits this information to the inspection host.

[0028] Specifically, the dual-view infrared temperature measurement gimbal captures infrared images, allowing you to understand the temperature distribution of equipment and promptly identify temperature-related anomalies. It also supports nighttime photography. Combining normal light images with infrared images provides a more comprehensive understanding of equipment status, improving the accuracy of fault diagnosis.

[0029] There are multiple spherical cameras, all of which are fixedly installed at monitoring points in the substation (such as the area corresponding to the main transformer, emergency equipment area, switch cabinet and circuit breaker area and other important areas) to monitor the operating environment and equipment status of important areas.

[0030] The intelligent lighting controller senses the ambient light based on its built-in brightness sensor and adjusts the lighting brightness and color temperature according to the ambient light. It can provide fill light for the dual-view infrared temperature measurement gimbal to ensure the clarity of the normal light images captured.

[0031] The SF6 detection unit communicates with multiple SF6 gas sensors installed in key substation locations (such as switchgear, circuit breakers, and transformers, particularly key equipment like high-voltage switchgear and gas-insulated combination units). It monitors the temperature, humidity, concentration, and pressure of sulfur hexafluoride (SF6) at these locations and transmits this data to the inspection host. The inspection host generates an alarm based on the concentration, issuing an alert if the SF6 concentration exceeds a set safety threshold. Furthermore, the system analyzes SF6 gas for harmful decomposition products to assess equipment health. SF6 gas leaks not only degrade equipment insulation but also pose environmental risks (SF6 is a potent greenhouse gas). Under high temperatures or arcing, SF6 can decompose to produce toxic substances such as SF4 and SOF2, which pose potential threats to both equipment and human health. The SF6 detection unit and the inspection host can promptly detect gas leaks and pressure anomalies in the substation, ensuring safe substation operation.

[0032] In addition, those skilled in the art can also use oxygen sensors to collect oxygen concentrations in key areas and send them to the inspection host. Since SF6 gas leakage can cause localized oxygen deficiency, the inspection host will issue an alarm when the oxygen concentration falls below the safe limit.

[0033] The transformer oil chromatography online analysis unit is specifically designed to monitor the dissolved gas content in transformer oil. Using techniques such as gas chromatography, it can monitor the real-time concentrations of various dissolved gases in transformer oil, including hydrogen (H2), methane (CH4), ethane (C2H6), ethylene (C2H4), acetylene (C2H2), carbon monoxide (CO), and carbon dioxide (CO2). During normal operation, transformer oil and solid insulation gradually age and deteriorate, releasing very small amounts of gases. When the transformer experiences internal overheating, discharge faults, or moisture in the internal insulation, the levels of these gases gradually increase. Monitoring these gas levels can promptly identify potential transformer faults and provide important evidence for fault early warning. Furthermore, different types of faults can cause variations in the content and ratio of dissolved gases in transformer oil. For example, localized overheating may lead to increased ethylene and methane levels, while discharge faults may significantly increase acetylene levels. Therefore, monitoring the content and ratio of dissolved gases in transformer oil can help determine the type and severity of the fault.

[0034] Furthermore, the substation intelligent inspection module communicates with the electrical error prevention module to obtain the module's device operational status, preventing the inspection robot from accidentally contacting energized areas. For example, if the module detects that a device is in an operational state or presents a risk of misoperation, the robot can halt its current inspection mission or mark it as a faulty area, automatically navigating to the nearest non-faulty area to resume its current inspection mission.

[0035] Specifically, the patrol robot conducts inspections according to the inspection route and receives In this embodiment of the present application, the high-voltage cable fault warning module is configured to monitor the high-voltage cable's temperature, sheath current, operating environment, and partial discharge (PD) value in real time and send the information to the central management module. It then issues an alarm if the temperature, sheath current, operating environment, or PD value of the high-voltage cable exceeds a set threshold.

[0036] like Figure 3 As shown, the high-voltage cable fault warning module includes a cable temperature monitoring unit, a cable sheath circulating current monitoring unit, a cable video monitoring unit, a cable online partial discharge monitoring unit and an alarm unit.

[0037] Specifically, the cable temperature monitoring unit is used to acquire real-time temperature data of the high-voltage cable via a temperature-sensing optical fiber installed on the surface of the high-voltage cable and transmit it to the central management module. The cable temperature monitoring unit also includes a temperature measurement host. The temperature measurement host is communicatively connected to an optical transmitter and an optical receiver located at each end of the temperature-sensing optical fiber, receiving optical data from the optical receiver and converting the received optical data into temperature data. The cable sheath circulating current monitoring unit is communicatively connected to a current transformer located at the ground terminal of the high-voltage cable to acquire the sheath circulating current of the high-voltage cable and transmit it to the central management module. The cable video monitoring unit is communicatively connected to cameras installed at intervals on the high-voltage cable bridge to capture the operating environment of the high-voltage cable and transmit it to the central management module. The cable online partial discharge monitoring unit is communicatively connected to a partial discharge collector located at the ground terminal of the high-voltage cable to acquire the partial discharge value of the high-voltage cable in real time and transmit it to the central management module. The alarm unit is used to acquire temperature data, sheath circulating current, and partial discharge value, and compare them to see if they exceed set thresholds. An alarm is generated when the temperature data, sheath circulating current, or partial discharge value exceeds the set threshold.

[0038] For example, the high-voltage cable here is a 35kV single-core cable. The temperature threshold is set at 55°C in winter and 70°C in summer. The sheath current threshold is set at 5A. The partial discharge threshold is set at 500pC amplitude and 100 frequency. Each high-voltage cable corresponds to a channel, enabling one-to-one monitoring of the cable's temperature, sheath current, and partial discharge.

[0039] Furthermore, the operating environment data collected by the cable video monitoring unit is named according to different locations of the bridge and sent to the central management module to ensure that the bridge and cable loop names can be quickly located when the high-voltage cable is abnormal.

[0040] In this embodiment of the present application, the electrical monitoring module is configured to: acquire real-time operational data from the substation's power system to monitor for anomalies; identify potential faults by analyzing historical operational data to ensure stable grid operation; and transmit the operational data and identified potential faults to the central management module.

[0041] like Figure 4 As shown, the electrical monitoring module includes a monitoring server, an electrical monitoring switch, a reporting unit and an electrical monitoring operation unit.

[0042] Specifically, the monitoring server is communicatively connected to multiple sensors for real-time monitoring of the power system's operating data and for performing anomaly analysis based on the monitored operating data. The electrical monitoring switch is communicatively connected to the monitoring server, the reporting unit, and the electrical monitoring operation unit for data exchange between the monitoring server, the reporting unit, and the electrical monitoring operation unit, and for transmitting operating data to the central management module. The switch receives dispatch instructions from the central management module and transmits them to the electrical monitoring operation unit. The reporting unit generates graphic reports based on the operating data monitored by the monitoring server. The electrical monitoring operation unit generates operational instructions based on the results of the monitoring server's anomaly analysis to assist personnel in handling anomalies. The switch then executes the received dispatch instructions.

[0043] Furthermore, the sensors that are communicatively connected to the monitoring server include current sensors, voltage sensors, temperature sensors, and humidity sensors. These sensors are deployed at various key locations in the power system and are used to collect real-time operating data of the power system, namely, parameters such as current, voltage, temperature, and humidity of the power system. The sensors can transmit the collected data to the monitoring server via wired or wireless means. By monitoring the operating data of the power system in real time and performing anomaly analysis, potential faults can be discovered and handled in a timely manner, thereby improving the stability and reliability of the power system. If anomalies are identified in the operating data, the results of the anomaly analysis are sent to the electrical monitoring operation unit. For example, the anomaly analysis here can be performed by setting a threshold or by machine learning.

[0044] The electrical monitoring and operation unit generates operational instructions based on the results of the abnormality analysis and sends them to the staff so that they can handle the abnormality. Or it can cut off part of the circuit according to the dispatch instructions received to ensure the safety of the power system.

[0045] The report unit analyzes operational data and user needs to design the report layout, style, and content, then selects appropriate chart types (such as bar charts, line charts, and pie charts) to present the data. Graphical reports can also be automatically generated based on pre-existing templates and formats.

[0046] In an embodiment of the present application, the fault recording module is configured to record the changing waveform of the operating data before and after the abnormality according to the abnormality monitoring result of the electrical monitoring module, and send it to the central management module.

[0047] like Figure 5 As shown, the fault recording module includes a fault recording working unit and a fault recording switch that are communicatively connected.

[0048] Specifically, the fault recording work unit is used to: record the changing waveform of the operating data before and after the abnormality according to the results of the abnormality monitoring of the electrical monitoring module. Record the corresponding target waveform according to the dispatch instruction. The fault recording switch is used to receive the changing waveform and target waveform from the fault recording work unit and send them to the central management module, receive the dispatch instruction from the central management module, and send the dispatch instruction to the fault recording work unit. The anti-error workstation unit is used to verify the authority of the operator. Record the operation log according to the operator's operation and send the operation log to the anti-error server. Adjust the authority verification result in response to the instruction of the central management module. The remote viewing work unit is used to monitor key areas in the substation using a remote viewing camera to prevent emergencies. And send the captured monitoring data to the anti-error server. The anti-error server is used to encrypt the received monitoring data and operation log and send them to the central management module. And transcode the monitoring data and / or operation log according to bandwidth requirements and resolution.

[0049] Furthermore, by recording fluctuations in operating data before and after an anomaly—that is, waveform data of parameters such as current, voltage, and temperature—then and after the anomaly occurs, the fault point can be more accurately located and appropriate repair measures can be taken. The fault recording unit can also record target waveforms (current, voltage, etc.) over a specific period of time based on dispatch instructions from the central management module and send them to the fault recording switch, which then sends them to the central management module.

[0050] In an embodiment of the present application, the electrical error prevention module is configured to perform simulation rehearsals and logical judgments on switching operations to prevent power grid accidents.

[0051] like Figure 6 As shown, the electrical error prevention module includes an error prevention workstation unit, a remote viewing work unit and an error prevention server.

[0052] Specifically, the error prevention workstation unit is used to verify operator permissions. It records an operation log based on the operator's actions and sends the log to the error prevention server. It adjusts the permission verification results in response to instructions from the central management module. It simulates and conducts logical judgments on the operator's switching operations. The remote viewing workstation is used to monitor key areas in the substation using remote viewing cameras to prevent emergencies. It also sends the captured monitoring data to the error prevention server. The error prevention server is used to encrypt the received monitoring data and operation log and send them to the central management module. Furthermore, it transcodes the monitoring data and / or operation log based on bandwidth requirements and resolution.

[0053] Furthermore, the anti-error workstation unit can verify the operator's permissions based on their facial image or the account (or password) they entered, and then unlock the corresponding space (for example, by controlling an electronic lock to open the corresponding electrical box or operating room). It also records the operator's operation log to facilitate fault tracing. Furthermore, staff can apply for operating permissions through the anti-error workstation unit. The anti-error workstation unit sends the staff member's request to the central management module via the anti-error server. After the central management module approves it (which is pushed to the corresponding management personnel for manual approval), the anti-error workstation unit adjusts the staff member's permissions.

[0054] The error-prevention workstation unit also provides a simulation environment for staff training. This environment allows operators to rehearse and logically evaluate switching operations. By performing logical analysis on each operator's actions, the correctness and completeness of the operations can be verified. This helps improve operators' operational skills and safety awareness, thereby enhancing the safety and reliability of the power system and ensuring the stability and continuity of power supply.

[0055] The anti-error server encrypts monitoring data and operation logs to prevent unauthorized access or tampering, enhancing system security. Furthermore, the anti-error server determines the appropriate resolution and bitrate for data transcoding based on current bandwidth and resolution requirements. This is particularly true for monitoring data involving large amounts of video, which can slow transmission.
