[0045] Relay protection of power systems is one of the key links to ensure safe and stable operation of power grids. In traditional relay protection systems, the relay protection room usually relies on cable number plates to identify circuit numbers and terminal numbers, and uses paper drawings to indicate circuit principles and wiring methods. Although this method meets the needs of construction, commissioning, operation and maintenance to a certain extent, with the increasing complexity of power systems and technological advances, the limitations of traditional methods are gradually emerging.

[0046] In recent years, with the development of smart substations, the design of secondary circuits has been digitized, and sampling values, protection control signals, etc. are digitally encoded and transmitted through optical fibers. This change has brought about a "one-to-many" relationship between physical media (such as optical fibers) and signals, that is, one fiber core can transmit multiple different information at the same time. However, in practical applications, these optical fibers are still identified by traditional cable number plates or optical cable numbers, which can describe very limited information.

[0047] In actual operation, such as when debugging equipment or troubleshooting, workers often need to frequently refer to SCD files (System Configuration Description) and cable connection diagrams. This not only increases the workload, but can also lead to errors. In addition, during the construction phase, when printing labels, it is also necessary to refer to the cable connection diagram and enter information one by one. This process is cumbersome and inefficient, and fails to fully utilize the advantages of digital design.

[0048] Therefore, this application proposes a relay protection visualization monitoring method, system, equipment and medium, so as to conveniently, quickly and comprehensively display the full path information and virtual circuit information of the optical cable, achieve the goal of panoramic visualization status monitoring of relay protection, and improve the working efficiency and reliability of the relay protection system.

[0049] In a first aspect, an embodiment of the present application provides a method for visual monitoring of relay protection. Figure 1 It is a flow chart of visual monitoring of relay protection, such as Figure 1 As shown, a visual monitoring method for relay protection includes:

[0050] Step S101: receiving the physical port information entered in the SCD file, and creating a target SCD file, wherein the target SCD file includes the logical virtual circuit information between the intelligent electronic devices.

[0051] Step S102: construct a topology diagram of the physical port connection relationship based on the physical port information in the target SCD file and the connection relationship of the power plant optical fiber. The topology diagram is used to describe the real-loop connection relationship of the physical ports of the intelligent electronic device.

[0052] Step S103: Match the logical virtual circuit according to the topology diagram, establish the corresponding relationship between the virtual circuit and the real circuit, and monitor the corresponding relationship on the terminal in a graphical interface.

[0053] In summary, the embodiment of the present application provides a method for visual monitoring of relay protection, which creates a target SCD file by receiving the entered physical port information in the SCD file, and the target SCD file includes the logical virtual circuit information between the intelligent electronic devices. According to the connection relationship between the physical port information in the target SCD file and the optical fiber of the power plant, a topological diagram of the physical port connection relationship is constructed, and the topological diagram is used to describe the physical port real circuit connection relationship of the intelligent electronic device. According to the topological diagram, the logical virtual circuit is matched, the correspondence between the virtual circuit and the real circuit is established, and the correspondence is monitored on the terminal with a graphical interface. The virtual circuit is automatically matched through the physical port information, and the virtual-real correspondence is displayed in a graphical manner, and the on-off status of the physical connection and the virtual circuit is monitored in real time, thereby realizing the panoramic visual status monitoring of the secondary information circuit of the intelligent power plant combined with the virtual circuit and the real circuit, improving the visual monitoring efficiency and expanding the monitoring range. Solve the problems of low visual monitoring efficiency and narrow monitoring range in the related technology.

[0054] In one embodiment, step S101, receiving the physical port information entered in the SCD file, creating a target SCD file, the target SCD file including the logical virtual circuit information between the intelligent electronic devices. Specifically including:

[0055] The physical port information is entered into the physical connection sub-file in the IED information folder, where the physical port information includes the IED's physical port number, port type, connection status, and name of the connection object.

[0056] Optionally, during the configuration process of the smart substation, the physical port information is entered into the physical connection subfolder in the SCD file through a specific tool or software (which is prior art and will not be described again). This information includes but is not limited to the physical port number, port type (such as optical port, electrical port), connection status (such as connected, not connected) of the intelligent electronic device (IED), and the IED name of the connected object. The target SCD file is a new version of the SCD file generated by adding physical port information on the basis of the original SCD file. This file not only contains the original logical virtual circuit information, but also records in detail the physical connection details between IEDs, so that the SCD file can fully reflect the logical configuration and physical connection status of the IED. Logical virtual circuit information. Logical virtual circuit information refers to the virtual connection information established by intelligent electronic devices (IEDs) in smart substations through network communication protocols (such as GOOSE, SV, etc.). These connections do not rely on traditional hard wiring, but are transmitted on the network through digital signals, including the logical nodes (LN) and data objects (DO) of IEDs: Each IED contains multiple logical nodes, and the logical nodes contain data objects, which are the basic units of information interaction between IEDs.

[0057] By adding physical port information to the SCD file, the SCD file is upgraded from a simple logical configuration description to a comprehensive configuration file containing physical connection details. This step enables the SCD file to more comprehensively describe the secondary system of the substation, providing a solid foundation for the subsequent construction of the physical connection topology and the establishment of the virtual-real correspondence. The entry of physical port information allows the physical connections between IEDs to be clearly marked in the SCD file, making it easier for designers and construction personnel to understand the physical connection relationship between IEDs.

[0058] In one embodiment, step S102, based on the physical port information in the target SCD file and the connection relationship between the power plant optical fiber, a topological diagram of the physical port connection relationship is constructed, and the topological diagram is used to describe the real loop connection relationship of the physical port of the intelligent electronic device. Specifically, it includes:

[0059] Optionally, in the target SCD file, the physical port information coexists with the logical virtual circuit information between each intelligent electronic device (IEDs). Using this physical port information, combined with the connection relationship of the power plant fiber optic network, the system can construct a detailed physical port connection relationship topology diagram. This topology diagram not only shows the physical connection between IEDs, but also indicates the type, status and object of the connection, making the complex network structure visual and easy to understand. The physical connection relationship between IEDs is automatically analyzed based on the physical port number, port type, connection status and IED name of the connection object of the IEDs. By traversing the information in the SCD file, the system can identify which IEDs are directly or indirectly connected through which physical ports, as well as the nature of these connections (such as optical cable, twisted pair, etc.).

[0060] Step S102 achieves a high degree of visualization of the physical connections of the secondary system of the smart substation by constructing a topological diagram of the physical port connection relationship, significantly improves the monitoring efficiency of relay protection, and effectively combines the abstract logical information in the SCD file with the actual physical connection to form a visualization that comprehensively reflects the physical architecture, solving the problem of narrow monitoring range of relay protection.

[0061] In one embodiment, step S103, according to the topology diagram, matches the logical virtual circuit, establishes the correspondence between the virtual circuit and the real circuit, and monitors the correspondence on the terminal with a graphical interface. Specifically includes:

[0062] By traversing the physical port information in the topology map and the target SCD file, the real circuit of the physical port on the topology map is matched with the logical virtual circuit, and the corresponding relationship between the real circuit and the virtual circuit is established.

[0063] Optionally, by traversing the topology map and the physical port information in the target SCD file, the real circuit at the physical level can be matched with the virtual circuit at the logical level, thereby establishing a corresponding relationship between the real circuit and the virtual circuit.

[0064] Figure 2 is a flow chart showing a corresponding relationship between a virtual loop and a real loop according to an exemplary embodiment, such as Figure 2 As shown, by traversing the topology map and the physical port information in the target SCD file, the real circuit of the physical port on the topology map is matched with the logical virtual circuit to establish the corresponding relationship between the real circuit and the virtual circuit. The following steps are included:

[0065] Step S1031: read the physical port information of the local intelligent electronic device from the target SCD file.

[0066] Optionally, the target SCD file contains detailed configuration information of IEDs, including logical virtual circuits and physical port information. Step S1031 is to read the physical port information of the local IED from the SCD file, which is the basis for the subsequent matching of real circuits and virtual circuits. It ensures that the IED can be accurately located from the physical level in the subsequent steps, providing key data for the matching of real circuits and virtual circuits.

[0067] Step S1032: Using the physical port of the local intelligent electronic device as the search starting point, traverse from the starting point to the physical port of the opposite intelligent electronic device according to the physical connection relationship in the topology diagram, and obtain the path of the real loop from the local physical port to the opposite physical port.

[0068] Optionally, the physical connection relationship recorded in the topology diagram is used to find the path to the physical port of the opposite IED from the physical port of the local IED through a traversal algorithm. A physical path from the local IED to the opposite IED is established, providing physical path information for the subsequent matching of the logical virtual circuit and the physical real circuit.

[0069] Step S1033: Find the logical virtual circuit corresponding to the intelligent electronic device name and physical port information in the target SCD file.

[0070] Optionally, in the SCD file, the IED name and physical port information are associated with the logical virtual circuit. By matching the IED name and the physical port information, the corresponding logical virtual circuit is found.

[0071] Step S1034: Determine the logical path of the virtual circuit according to the intelligent electronic device name and the logical node information.

[0072] Optionally, the IED name and the logical node information together constitute the identification of the logical virtual circuit, and the path of the virtual circuit at the logical level can be determined through this information, thereby clarifying the logical path of the logical virtual circuit.

[0073] Step S1035: Map the path of the logical virtual loop and the path of the real loop to establish a corresponding relationship between the virtual loop and the real loop.

[0074] Optionally, by mapping the physical path obtained in step S1032 with the logical path determined in step S1034, the correspondence between the logical virtual circuit and the physical real circuit is achieved, ensuring that the data exchange at the logical level is consistent with the actual connection at the physical level.

[0075] Through the correspondence between the real circuit and the virtual circuit, the on / off status of the physical connection and the virtual circuit is monitored in real time, thus realizing the panoramic visualization status monitoring of the secondary information circuit of the smart power plant combining the virtual circuit and the real circuit. This solves the problems of low visualization monitoring efficiency and narrow monitoring range in related technologies.

[0076] In one embodiment, the physical port information is entered into a physical connection subfile in the intelligent electronic device information folder, wherein the physical port information includes the physical port number, port type, connection status and name of the connection object of the intelligent electronic device.

[0077] Optionally, in the secondary information loop of the smart substation, the physical port information is the key data connecting IEDs (intelligent electronic devices), which determines how IEDs communicate through physical media (such as optical fiber or cable). Entering these physical port information into the physical connection subfile in the intelligent electronic device information folder is an important step to ensure the integrity and accuracy of the SCD file (system configuration description file). Specifically, the physical port description is added in the "intAddr" attribute of the "ExtRef" element, as shown in the following example:

[0078] <ExtRef daName=“stVal”doName=“Pos”iedName=“IL2201A”ldInst=“RPIT”lnClass=“XCBR”lnInst=“1”prefix=“Q0A”intAddr=“1-A:PIGO / GOINGGIO1.DPCSO1.stVal” / >

[0079] The ExtRef element is used to identify the intelligent electronic device information, including the name, logical node class, data object, and data attributes of the intelligent electronic device, and the intAddr attribute is used to identify the physical port information of the intelligent electronic device.

[0080] In one embodiment, before constructing a topology diagram of the physical port connection relationship based on the physical port information in the target SCD file and the connection relationship between the power plant optical fiber, the method further includes:

[0081] Obtain message information by sniffing process layer messages and MMS messages; identify the status of the physical connection.

[0082] According to the message information, identify whether the status of the physical connection is normal, including whether the status of the physical connection is normal, whether there is data loss or delay, and whether the communication is interrupted.

[0083] When the identification result is an abnormal state, an alarm is issued and corresponding processing is performed according to the alarm, wherein the abnormal state includes data loss, delay or communication interruption.

[0084] Optionally, the communication between IEDs is monitored at the physical level to capture process layer messages such as GOOSE, SV, and MMS messages. These messages carry data exchange information between IEDs, such as state changes, measured values, etc. By analyzing the captured message information, the system can determine the status of the physical connection, including whether it is normal, whether there is data loss or delay, whether the communication is interrupted, etc. For example, if the arrival frequency of the message is lower than the preset threshold, or the order of the message is disordered, it may indicate that there is data loss or delay; if no message from a specific IED is received for a period of time, the communication may be interrupted. Once it is identified that the physical connection is in an abnormal state (such as data loss, delay, or communication interruption), the system will trigger an alarm mechanism and take corresponding countermeasures according to the preset processing flow, such as trying to reconnect, starting a backup communication path, or notifying maintenance personnel.

[0085] By monitoring the physical connection status in real time, the system can respond quickly to abnormal situations and reduce system instability caused by communication failures. When a physical connection abnormality is identified, the system can dynamically adjust resource allocation according to actual conditions, such as enabling redundant links to ensure continuous transmission of critical data.

[0086] In one embodiment, the corresponding relationship is monitored on the terminal using a graphical interface, specifically including:

[0087] The corresponding relationship can be monitored on the terminal in a graphical interface through a QR code label and / or a database storing the corresponding relationship between the virtual circuit and the real circuit.

[0088] Optionally, each IED (intelligent electronic device) or physical port is provided with a QR code label, which contains the name of the IED, the physical port information, and the virtual circuit information related thereto. When the operation and maintenance personnel scan the QR code using a mobile terminal, the terminal will automatically call the corresponding relationship database stored locally or on the server to display the virtual and real circuit connection information related to the IED or physical port. Alternatively, the corresponding relationship can be directly viewed based on the database storing the corresponding relationship between the virtual circuit and the real circuit.

[0089] Through the combined use of QR code tags and databases, operation and maintenance personnel can quickly obtain the required virtual-real circuit correspondence information anytime and anywhere without relying on paper documents or memory, greatly improving work efficiency.

[0090] In summary, the embodiment of the present application provides a method for visual monitoring of relay protection, which creates a target SCD file by receiving the entered physical port information in the SCD file, and the target SCD file includes the logical virtual circuit information between the intelligent electronic devices. According to the connection relationship between the physical port information in the target SCD file and the optical fiber of the power plant, a topological diagram of the physical port connection relationship is constructed, and the topological diagram is used to describe the physical port real circuit connection relationship of the intelligent electronic device. According to the topological diagram, the logical virtual circuit is matched, the correspondence between the virtual circuit and the real circuit is established, and the correspondence is monitored on the terminal with a graphical interface. The virtual circuit is automatically matched through the physical port information, and the virtual-real correspondence is displayed in a graphical manner, and the on-off status of the physical connection and the virtual circuit is monitored in real time, thereby realizing the panoramic visual status monitoring of the secondary information circuit of the intelligent power plant combined with the virtual circuit and the real circuit. Solve the problems of low efficiency and narrow monitoring range of visual monitoring in related technologies.
