Description

Technical Field

[0001] The present invention relates to the technical field of power management, and in particular to a secondary virtual circuit management system, method, device and storage medium. Background Art

[0002] At present, with the completion of construction of a large number of smart substations and the start of grid-connected operation, the challenges of smart substation operation and maintenance are becoming increasingly prominent. The SCD (Substation Configuration Description File) file of the smart substation, that is, the system configuration description file of the entire station, is based on the IEC61850 standard and is used to describe the information of all equipment in the entire substation, including the primary system, secondary equipment and communication network configuration. It plays a vital role in the smart substation. It establishes an overall model for the entire substation, clarifies the relationship between each secondary device, and provides key support for the troubleshooting of relay protection commissioning personnel.

[0003] The secondary virtual circuit mapping in the SCD file configuration of the smart substation reflects the configuration and connection relationship of the secondary equipment in the station, which is the core of the SCD file configuration. However, as the scale of smart substations increases, the number of secondary virtual circuits configured in the SCD file increases. When the secondary virtual circuit of the SCD file changes, the SCD file often needs to be modified and configured. There is a lack of relevant safeguards for the remaining secondary virtual circuits that do not involve modification. For the secondary virtual circuits that are accidentally modified or deleted by humans outside the scope of the work, they can only be compared manually, which is prone to omissions and difficult to ensure efficiency and accuracy. Summary of the invention

[0028] Embodiment 1

[0029] Figure 1 A structural diagram of a secondary virtual circuit management system is provided for the first embodiment of the present invention. This embodiment is applicable to the case where a secondary virtual circuit is changed. The method can be executed by a secondary virtual circuit management device. The secondary virtual circuit management device can be implemented in the form of hardware and / or software. The secondary virtual circuit management device can be configured in an electronic device. Figure 1 As shown, the system includes a configuration description file library 101, a change application module 102, a change authorization module 103 and a file modification module 104.

[0030] The configuration description file library 101 is used to store the system configuration description file corresponding to the system, wherein the system configuration description file at least includes a secondary virtual circuit between secondary devices, and the virtual terminals of the secondary devices are configured with initial virtual terminal feature codes.

[0031] Among them, the system configuration description file may refer to a substation SCD file (Substation Configuration Description File). It is a file type defined in accordance with the IEC 61850 international standard and is mainly used in smart substations. The system configuration description file describes the configuration information between the primary equipment (main equipment such as transformers, circuit breakers, etc.) and secondary equipment (control, protection, measurement equipment, etc.) of the entire substation. The system configuration description file is crucial to ensure the correct communication between the various intelligent electronic devices (IEDs, Intelligent Electronic Devices) in the substation. It establishes a complete digital model for the substation, allowing different devices to recognize each other and work together.

[0032] For example, in the power system, the substation is a key node for transmitting electric energy from the power plant to the user, and its internal equipment can be roughly divided into two categories according to its function: primary equipment and secondary equipment. Among them, the primary equipment is directly involved in the power conversion, transmission, distribution and control process in the power system. They usually deal with high voltage and high current. The main primary equipment includes but is not limited to: transformers, circuit breakers, disconnectors, busbars, power cables and lightning arresters. Secondary equipment is mainly used to monitor, protect, control and adjust the working status of primary equipment. They deal with lower voltage levels and usually indirectly affect the operation of the power system through signals or data. Secondary equipment can refer to intelligent electronic devices. For example, common secondary equipment includes: relays, protection devices, control devices, metering instruments, communication equipment and automation systems.

[0033] Secondary virtual circuits are used to describe the logical connection relationship between secondary devices in smart substations. These logical connections are used for data transmission and exchange, especially in control, protection and measurement. It should be noted that there is a close relationship between secondary virtual circuits and system configuration description files, and secondary virtual circuits are an important part of system configuration description files.

[0034] It should be noted that Virtual Terminal is a concept in smart substations based on the IEC 61850 standard. A virtual terminal refers to a logical connection point that is used to describe how data is exchanged between secondary devices. The virtual terminal connection status of each secondary device reflects the logical position of the device in the network and the data interaction mode between it and other devices. These connections are described in detail through the system configuration description file, and in practical applications, the correct communication and coordination between secondary devices are ensured. The initial virtual terminal feature code can be generated by the feature code generation module to identify the connection information of each virtual terminal at the initial moment. It should be noted that when the connection relationship of the virtual terminal changes, the feature code corresponding to the virtual terminal will also change.

[0035] The change application module 102 is used to receive a configuration change request for the secondary device, and pre-modify the secondary virtual circuit corresponding to the secondary device according to the configuration change request to obtain a change application file.

[0036] The configuration change request may refer to a change request for modifying the function of the secondary device, wherein the configuration change request at least includes the relevant work tasks and work scope of the secondary device, etc. The change application file may refer to a configuration description file after pre-modification of the secondary virtual circuit.

[0037] Specifically, when there is work involving changes to the secondary virtual circuit, an application needs to be made on the system change application module 102. The change application module 102 pre-modifies the secondary virtual circuit according to the configuration change request, and after the modification, the change application module 102 generates a change application file according to the corresponding modified change situation.

[0038] Exemplarily, the change application module includes: a request parsing unit, used to parse the configuration change request to determine the configuration change information corresponding to the secondary virtual circuit; a configuration pre-modification unit, used to pre-modify the secondary virtual circuit based on the configuration change information to obtain a change application file.

[0039] Specifically, the request parsing unit parses the configuration change request to determine the configuration change information corresponding to the secondary virtual circuit, such as related work tasks and work scope, etc. The configuration pre-modification unit pre-modifies the secondary virtual circuit according to the configuration change information to obtain a change application document.

[0040] Exemplarily, a pre-modification unit is configured to: after the secondary virtual circuits are pre-modified, aggregate the pre-modified secondary virtual circuits, and integrate the pre-modification items to obtain a change application document.

[0041] Specifically, the secondary virtual circuits that have been pre-modified are summarized, and the modification items corresponding to the secondary virtual circuits are integrated, so that the change application document can be obtained.

[0042] The change authorization module 103 is used to review the change application document, obtain the reviewed standard application document, and assign authorization verification information to the standard application document, wherein the authorization verification information at least includes the secondary equipment virtual terminal connection change information.

[0043] The standard application document may refer to a change application document that has passed review. The authorization verification information may refer to identification information of the standard application document.

[0044] Specifically, the change application document is reviewed and processed by the change authorization module 103. The review method can be that the change application document is reviewed by manual review using the change authorization module 103, or that the change application document is reviewed by the review program using the change authorization module 103, or that the change application document is reviewed by manual review and the review program together. After the change application document passes the review, the change application document is determined as a standard review document, and authorization verification information is assigned to the standard review document. The authorization verification code contains information about the relevant virtual terminals in the secondary virtual circuit that needs to be changed.

[0045] Exemplarily, the change authorization module is also used to reject the configuration change request and stop generating the authorization verification information when the change application document fails to pass the review.

[0046] The file modification module 104 is used to parse the authorization verification information, determine the file modification range corresponding to the secondary virtual circuit, and modify the secondary virtual circuit based on the file modification range and the standard application file.

[0047] Specifically, after the standard application file is imported into the file modification module 104, the file modification module 104 will prompt to input the corresponding authorization verification information, and the file modification module 104 will parse the authorization verification information to determine the file modification range corresponding to the secondary virtual circuit. In addition, when the authorization verification information is correctly input, the file modification module 104 will open the secondary virtual circuit modification authority related to the standard application file. The file modification module 104 modifies the secondary virtual circuit according to the file modification range and the standard application file.

[0048] Exemplarily, the system also includes a feature code generation module, which is used to determine the initial connection information of the secondary device in the system according to the secondary virtual circuit in the system configuration description file, and for each secondary device, generate an initial virtual terminal feature code corresponding to the virtual terminal of the secondary device according to the initial connection information, or to generate a changed virtual terminal feature code corresponding to the virtual terminal of the secondary device based on the changed connection information of the virtual terminal of the secondary device after modifying the secondary virtual circuit.

[0049] It should be noted that the feature code corresponding to the virtual terminal of the secondary device will change as the connection state of the secondary device changes. The feature code corresponding to the virtual terminal of the secondary device is generated by the feature code generation module. In other words, the feature code generation module generates a feature code for the virtual terminal of the secondary device when the secondary virtual circuit is in the initial state, or generates a change virtual terminal feature code for the virtual terminal of the secondary device when the secondary virtual circuit changes.

[0050] Specifically, when the connection state of the secondary device virtual terminal is the initial state, the initial connection information (such as internal information, internal signal description, receiving port, external information, external signal description, etc.) of the secondary device in the system is determined. According to the initial connection information, an initial virtual terminal feature code is generated for each secondary device virtual terminal. Alternatively, after the secondary virtual circuit modification process occurs, based on the changed connection information of the virtual terminal of the secondary device, a changed virtual terminal feature code is generated for all secondary device virtual terminals.

[0051] Exemplarily, the system also includes a feature code comparison module; wherein the feature code comparison module is used to determine, for each of the secondary device virtual terminals, a target secondary virtual circuit whose connection has changed based on the changed virtual terminal feature code and the initial virtual terminal feature code, and store the target secondary virtual circuit in the configuration description file library.

[0052] It should be noted that after the secondary virtual circuit is modified, the modified secondary virtual circuit needs to be stored in the configuration description file library. Specifically, when the secondary virtual circuit is modified and needs to be uploaded to the management system, the system will again generate a changed virtual terminal feature code for all secondary virtual circuits in the system configuration description file through the feature code generation module, and then compare the changed virtual terminal feature code with the initial virtual terminal feature code through the feature code comparison module, and prompt the secondary virtual circuit with a changed feature code, and perform a second confirmation. After confirmation, the target secondary virtual circuit with a changed connection is saved in the system configuration description file.

[0053] Exemplarily, the feature code comparison module is further used for:

[0054] Before storing the target secondary virtual circuit in the configuration description file library, the change information corresponding to the target secondary virtual circuit is compared with the configuration change request, and when the change information and the configuration change request correspond to each other, the target secondary virtual circuit is stored in the configuration description file library.

[0055] Specifically, before storing the target secondary virtual circuit in the configuration description file library, the change information of the target secondary virtual circuit needs to be compared with the received configuration change request. When the change information and the configuration change request correspond to each other, the target secondary virtual circuit is stored in the configuration description file library.

[0056] The technical solution of the embodiment of the present invention is to store the system configuration description file corresponding to the system through the configuration description file library, wherein the system configuration description file at least includes the secondary virtual circuit between the secondary devices, and the virtual terminal of the secondary device is configured with the initial virtual terminal feature code. A change application module is used to receive a configuration change request for the secondary device, and according to the configuration change request, pre-modify the secondary virtual circuit corresponding to the secondary device to obtain a change application file. A change authorization module is used to review the change application file, obtain a standard application file that has passed the review, and assign authorization verification information to the standard application file, wherein the authorization verification information at least includes the connection change information of the virtual terminal of the secondary device. A file modification module is used to parse the authorization verification information, determine the file modification range corresponding to the secondary virtual circuit, and modify the secondary virtual circuit based on the file modification range and the standard application file. The technical problem of lack of relevant safeguard measures due to the secondary virtual circuit that does not involve modification is solved, while reducing the risk of manual modification misoperation and improving the accuracy of secondary virtual circuit adjustment.
