Description

Technical Field

[0001] The present invention relates to a wave recording device, in particular to a wave recording device for power faults in an intelligent substation, belonging to the technical field of substations. Background Art

[0002] Power fault recorders, commonly known as fault recorders, are automatic recording devices used in power systems. They can record the dynamic changes in various electrical quantities, including current, voltage, and frequency, when a fault or anomaly occurs in the system.

[0003] Substations use transformers and other equipment to raise and lower the voltage of the electricity generated by power plants to meet the needs of users at different distances and voltage levels, and transmit electricity to various power consumption areas. Therefore, substations have a large number of lines.

[0004] When recording power faults on multiple lines using power fault recording equipment, it is generally necessary to use multiple recording equipment for recording detection. In order to save storage space, multiple recording equipment will be neatly arranged and placed, and each recording equipment is provided with buttons and a display screen for operation on the front. The cabinet door frame of the recording equipment is divided into two openable left and right doors. After opening the cabinet door frame on the outside, the recording equipment is controlled and detected through the operation buttons and the display screen. However, when multiple recording equipment are neatly placed, if multiple technicians are required to perform maintenance on multiple recording equipment at the same time, the open doors of adjacent cabinets will interfere with each other, causing inconvenience in maintenance and affecting the operation and use of the operators.

[0005] The power system is a complex and large system, and its stable operation is crucial to the normal development of the social economy. However, due to various reasons (such as equipment aging, natural disasters, human error, etc.), faults may occur in the power system. If these faults are not handled in a timely manner, they may cause serious consequences such as power outages, equipment damage, and even casualties. Although power systems often perform maintenance work to detect them, it is difficult to quickly locate the fault when a fault occurs. Therefore, this application proposes an intelligent substation power fault recording device. Summary of the Invention

When the mobile frame slides to the front of the corresponding fixed frame, the multiple operation buttons and display screens set on the front of the recording cabinet are exposed, which is convenient for operation and use. After use, the set mobile unit is used again to drive the mobile frame to slide vertically upward in front of the fixed frame until the mobile frame is reset. At this time, the front of the recording cabinet can be protected by the mobile frame and the fixed frame.

When multiple operation buttons and display screens need to be used, the provided moving unit can drive the moving frame to slide vertically downward in front of the fixed frame. When the moving frame slides to the front of the corresponding fixed frame, the multiple operation buttons and display screens provided on the front of the recording cabinet are exposed, which is convenient for operation.

Under the elastic force of the extrusion spring 47 , the extrusion block 46 is tightly pressed against the inner wall of the slide groove 25 .

[0055] Furthermore, a handle 421 is fixedly mounted on the front side of the linkage bar 42 .

[0056] During use, first pull the handles 421 on both sides toward the middle, so that the ends of the linkage bar 42 slide toward the inside of the positioning square tube 41, and then the other end of the linkage bar 42 drives the linkage block 44 to move horizontally. When the linkage block 44 moves horizontally, the other end of the linkage block 44 drives the extrusion block 46 to slide on the inner wall of the extrusion groove 45, compressing the extrusion spring 47 and separating the side of the extrusion block 46 from the inner wall of the slide groove 25.

When the recording cabinet 1 needs to be inspected as a whole, the cabinet door frame 2 can be directly opened for easy use.

[0058] By setting up a heat insulation unit 3, the heat insulation unit 3 is composed of a heat insulation strip 31, a plurality of heat dissipation slots 32 and a plurality of heat-conducting fins 33. The heat insulation strip 31 is set to block the two adjacent recording cabinets 1, and the heat on the side of the recording cabinet 1 is transferred to the plurality of heat dissipation slots 32 through the heat insulation strip 31 and the plurality of heat-conducting fins 33.

[0059] The recording cabinet 1 has a built-in merging unit, an acquisition unit, a recording unit, a management unit and a protection control unit connected in sequence. Specifically:

[0060] The merging unit is mainly responsible for collecting analog signals from multiple current transformers and voltage transformers, and synchronously processing, digitally converting and time-stamping these signals. The processed digital signals will be packaged into a standard message format. The acquisition unit receives the digital signals from the merging unit and sends the digital signals to the protection control unit. The protection control unit processes and judges these signals according to the preset protection logic and control strategy; when faults and abnormal conditions are detected in the power system, the protection control unit will take prompt measures to prevent the fault from expanding and protect the safety of the power system.

[0061] The acquisition unit includes a message acquisition module, a message analysis module, and a wave recording module which are connected in sequence.

[0062] The message collection module is responsible for receiving message data packets and converting the message data packets into a format that can be analyzed to obtain the converted message data packets;

[0063] The message analysis module is responsible for identifying the message type and analyzing the converted message data packets to obtain the analyzed data;

[0064] The recording module is responsible for calculating the real-time recording value and starting the recording based on the fault judgment criteria according to the analyzed data.

[0065] The message analysis module has built-in message parsing algorithms and data preprocessing algorithms. Specifically:

[0066] The message parsing algorithm is used to receive messages from the merging unit and the protection control unit, and these messages are parsed to extract the sampled value data and the switching quantity data. The specific communication protocol (such as IEC 61850) is parsed. After the data is extracted, the data is preprocessed by the data preprocessing algorithm, such as filtering, denoising, and standardization, to improve the accuracy and reliability of the data.

[0067] The recording unit includes a database module and a message recording module connected in sequence;

[0068] The database module is used to store the data uploaded by the acquisition unit and the analysis results;

[0069] The message recording module is responsible for recording and managing the received messages.

[0070] The recording unit has a built-in database and message recording and analysis algorithm connected in sequence;

[0072] The management unit includes a system configuration module, an online monitoring module, an offline analysis module and an external communication module which are connected in sequence.

[0073] The system configuration module is used to configure the system parameters and configuration;

[0074] The online monitoring module is used to monitor the system status and network message flow in real time;

[0075] The offline analysis module is used to perform fault analysis and waveform correlation analysis on the stored data;

[0076] The external communication module is responsible for communication and data exchange with the main station;

[0077] The management unit has built-in system configuration and parameter optimization algorithms, online monitoring and fault warning algorithms, and offline analysis algorithms.

[0078] Use system configuration and parameter optimization algorithms to configure system parameters and configurations, including parameter optimization algorithms such as parameter search and optimization based on genetic algorithms and particle swarm algorithms.

[0079] Online monitoring and fault warning algorithms are used to monitor the system status and network packet traffic in real time, and to implement fault warnings based on this data. Specifically, knowledge based on machine learning and deep learning is used to identify abnormal patterns and predict faults.

[0080] Offline analysis algorithms are used to perform fault analysis and waveform correlation analysis on the stored data, including signal processing, pattern recognition, and data mining.

[0081] The power fault recording equipment in the smart substation realizes real-time monitoring, recording and analysis of power system faults through the built-in management unit, recording unit and acquisition unit, as well as message parsing algorithm and data preprocessing algorithm. When the equipment fails, the fault location can be found quickly.

[0082] The acquisition unit and management unit devices can monitor the operating status of the power system in real time. Once an abnormality or potential fault is found, an early warning signal can be immediately issued to remind the operation and maintenance personnel to take timely measures to deal with it, which helps to prevent the fault from further expanding and reduce losses.

[0083] By collecting and analyzing various data in the power system, the equipment can accurately locate the location and cause of the fault, which provides valuable reference information for operation and maintenance personnel, enabling them to quickly find the problem and take effective repair measures;

[0084] The recording unit records various data during power system operation, including both normal and fault conditions. This data is crucial for subsequent analysis and troubleshooting. Through data analysis, operations and maintenance personnel gain a deeper understanding of the power system's operating status, identifying potential problems and hidden dangers, and providing a basis for optimizing and improving the power system.

[0085] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
