Description

Technical Field

[0001] This application relates to the field of power transmission and transformation equipment, specifically to a power transmission and transformation equipment and relay protection linkage system. Background Technology

[0002] With the progress and development of the times, people have increasingly higher requirements for the reliability of power supply. Transmission lines extend for tens or even hundreds of kilometers, traversing diverse geographical and meteorological environments. With the rapid development of municipal construction, construction vehicles and heavy machinery frequently operate beneath transmission lines, all of which become potential hazards affecting their normal operation. When a line fault occurs, the traditional fault location process is cumbersome and time-consuming. Therefore, shortening fault handling time and reducing the average power outage time for users is particularly important.

[0003] Currently, there is no relevant linkage system on the market. The power transmission system and the relay protection system operate separately and do not affect each other. However, when these two different systems, power transmission and transformation equipment and relay protection devices, interact, there are situations where line faults prevent them from linking.

[0004] However, in practice, data exchange does occur between the two disciplines, usually through manual information transmission. This results in a delay in the transmission of fault information, preventing real-time delivery. Summary of the Invention

[0005] In view of this, the embodiments of this application are committed to providing a power transmission and transformation equipment and relay protection linkage system. By setting up a power transmission and transformation equipment and relay protection linkage system including a protection and information system, an information push system and a power transmission equipment monitoring system, the real-time, targeted and proactive monitoring of the operation status of line equipment is improved.

[0006] According to one aspect of this application, an embodiment of this application provides a power transmission and transformation equipment and relay protection linkage system, characterized in that it includes: a protection and information system, which is communicatively connected to a relay protection device and a waveform recorder in the power line, and is used to collect and analyze fault information of the power line; an information push system, which is communicatively connected to the protection and information system, and is used to send information when the power line fails; and a power transmission equipment monitoring system, which is communicatively connected to the protection and information system, and is used to capture fault images of the power line.

[0007] In one embodiment, the information protection system includes: a first information protection substation fault analysis module, which is communicatively connected to the relay protection device and is used to analyze the status information of the power line after the relay protection device operates; and a second information protection substation fault analysis module, which is communicatively connected to the waveform recorder and is used to analyze the status information of the power line after the waveform recorder operates.

[0008] In one embodiment, the fault analysis module of the first protection substation calculates the fault phase, fault distance, and fault current based on the action information, waveform data, and corresponding settings and pressure plate status generated by the relay protection device.

[0009] In one embodiment, the fault analysis module of the first protection substation is configured to: acquire the result of the ranging information protection transmission; when the result of the ranging information protection transmission is successful, output the protection ranging; when the result of the ranging information protection transmission is unsuccessful, determine the result of the protection waveform analysis ranging; when the result of the protection waveform analysis ranging is successful, output the protection waveform analysis ranging; when the result of the protection waveform analysis ranging is unsuccessful, output an empty result.

[0010] In one embodiment, when both ends of the power line are faulty and there are fault recorders at both ends of the power line, the fault analysis module of the second information protection substation performs dual-end ranging calculation based on the analog data from the recorders at both ends and the line parameters.

[0011] In one embodiment, the second information protection substation fault analysis module is configured to: obtain the waveform recording results sent by the waveform recorders at both ends; when the waveform recording results sent by the waveform recorders at both ends are successful, determine the line parameter configuration result; when the line parameter configuration result is successful, determine the waveform recording category; when the waveform recording category is fault waveform recording, perform dual-end ranging calculation and output the dual-end ranging result.

[0012] In one embodiment, the information push system includes: a data interface, which is communicatively connected to the information protection system and is used to acquire data analysis results from the information protection system; an information content generation module, which includes an important warning identification system, a fault overview generation system, and an information template generation system, and is used to generate information content; a sending control system, which is used to generate an information sending list; and a sending interface, which is communicatively connected to the SMS modem and is used to send information to the SMS modem.

[0013] In one embodiment, the SMS modem is used to send information in a fixed pattern to the mobile phone of the relevant person or the corresponding interface server.

[0014] In one embodiment, the power transmission equipment monitoring system includes: an information receiving module for receiving and controlling fault information sent by the power transmission equipment monitoring system; an information analysis module for parsing the information content and extracting keywords according to built-in software, matching the keywords with devices in the power transmission equipment monitoring system, and using the matching result to trigger a photo-taking signal; and a camera for taking pictures.

[0015] In one embodiment, the matching mode between the keyword and the equipment in the power transmission equipment monitoring system includes: exact matching and fuzzy matching; the information analysis module selects the corresponding matching mode according to the fault level analyzed by the information protection system.

[0016] This application provides a linkage system for power transmission and transformation equipment and relay protection. The system uses a data transmission and transformation system (BRIS) as an intermediate module and employs two BRIS substation fault analysis modules to link data exchange between these two different professional systems. The BRIS collects and analyzes power line fault information and transmits it to an information push system. The data interface in the information push system can then obtain alarm information, fault report notifications, fault reports, and analysis reports. Next, by acquiring equipment models, personnel information, and permission information, a fixed-pattern SMS message can be generated in the information content generation module. The sending control system then generates an SMS sending list, and finally, the SMS message is transmitted to an SMS modem via a sending interface. The SMS modem is used to send SMS messages generated from the information analyzed during power line faults to the power transmission equipment monitoring system. Upon receiving the information, the power transmission equipment monitoring system receives and controls the fault information sent by the BRIS through its information receiving module. After the information analysis module parses and extracts keywords, it triggers a shooting command based on the keywords, and the camera captures images of the power line fault. Because the power transmission and transformation system enables linkage between power transmission and transformation equipment and relay protection devices, it solves the problem of triggering power transmission monitoring functions through relay protection signal actions, greatly improves the data exchange rate between the two specialized devices, and effectively shortens the maintenance time for power line faults.

[0057] Figure 5 The diagram shown is a structural schematic of an information push system according to an embodiment of this application. Figure 6 The diagram shown is a structural schematic of a text messaging modem provided in an embodiment of this application. Figure 5 , Figure 6 As shown, the information push system 2 includes:

[0058] Data interface 21 communicates with the information protection system 1 and is used to obtain the data analysis results from the information protection system 1; information content generation module 22 includes an important warning identification system, a fault summary generation system, and an information template generation system, and is used to identify fault conditions and generate information content; sending control system 23 is used to generate an information sending list; and sending interface 24 communicates with the SMS modem 25 and is used to send information to the SMS modem 25. The SMS modem 25 is used to send fixed-pattern information to relevant personnel's mobile phones or corresponding interface servers.

[0059] After the power line fault information is collected and analyzed by the information protection system 1 and transmitted to the information push system 2, the data interface 21 in the information push system 2 can obtain alarm information, fault report notifications, fault reports and analysis reports. The data interface 21 can also obtain equipment models, personnel information and permission information. After collecting the above information, the information content generation module 22 will generate SMS content in a fixed pattern. After generating the SMS content, an SMS sending list is generated by the sending control system 23. Finally, the SMS is transmitted to the SMS modem 25 through the sending interface 24. By setting the SMS modem 25, the SMS generated after analysis and processing can be quickly sent to the power transmission equipment monitoring system, which reduces the time required for information to be transmitted to the relevant personnel or equipment.

[0061] Information receiving module 31 is used to receive and control fault information sent by the information protection system 1;

[0062] Information analysis module 32 parses the information content and extracts keywords according to the built-in software, and matches the keywords with the equipment in the power transmission equipment monitoring system 3. The matching result is used to trigger the photo-taking signal.

[0063] And camera 33, which is used to take pictures.

[0064] The matching modes between the keywords extracted by the information analysis module 32 and the equipment in the power transmission equipment monitoring system 3 include: precise matching and fuzzy matching. Based on the fault level analyzed by the information protection system 1, the information analysis module 32 selects the corresponding matching mode to trigger image capture using keywords. Different keyword matching modes can handle different fault levels. When the fault level is low, fuzzy matching provides a faster matching speed, enabling quick resolution of faults in power lines. When the fault level is high, precise matching can handle more complex fault situations in power lines. Keyword commands prompt the camera to capture more accurate images, facilitating a more accurate understanding of the fault situation by operators. Additionally, the power transmission equipment monitoring system 3 can also install an image storage and display module, providing historical data support for operators to view fault images, retrieve historical images for comparison, and browse the latest fault images.

The sum of the double-end ranging values ​​at the local end and the double-end ranging values ​​at the opposite end equals the total line length.
