[0035] Embodiment 1

[0036] See also Figure 1 , shows a flow chart of a method for reconstruction, expansion and operation and maintenance of a substation provided by Embodiment 1 of the present invention, the method can be executed by a reconstruction, expansion and operation and maintenance device of a substation, the reconstruction, expansion and operation and maintenance device of the substation can be implemented in the form of hardware and / or software, and the reconstruction, expansion and operation and maintenance device of the substation can be configured in an electronic device. Figure 1 As shown, the method includes:

[0037] Step 101: When the electrical equipment of a substation is put into reconstruction and expansion as secondary equipment, the substation power grid model file is updated according to the electrical equipment.

[0038] In practical applications, substations are important facilities that use transformers to reduce the voltage of high-voltage electricity to the low-voltage electricity required by users. They include several major categories, such as high-voltage side equipment, low-voltage side equipment, and control and protection equipment.

[0039] Substations include master stations and substations, both of which are part of the substation. The master station of a substation is the core component of the substation. It centrally controls all electrical equipment in the substation, such as transformers, switch cabinets, cables, etc., is connected to the power grid, and monitors and controls the power grid. The substation of a substation is an auxiliary component of the master station, usually placed around or near the substation, responsible for collecting and transmitting the operating status of each electrical equipment in the substation and providing real-time data to the master station.

[0040] The main responsibilities and functions of the master station and the substation of the substation are different. The master station is responsible for mastering the operating status of each device in the substation, monitoring the stability of the power grid, ensuring the safe and stable operation of the power grid, and handling various emergencies. The master station is generally also the control center of the substation. It can control and dispatch various devices in the substation, such as opening or closing the switch cabinet, adjusting the output voltage of the transformer, etc. The main function of the substation is to collect and transmit the operating status data of each device in the substation, provide real-time data to the master station, and usually does not have the control function of the equipment.

[0041] The master station and substation of a substation also differ in their hierarchical structure. The master station is usually the highest level of a substation, while the substation is a subordinate level of the master station. The master station coordinates the operation status and data transmission of all substations.

[0042] In terms of specific electrical equipment, there are also differences between the master station and the substation of the substation. The master station is generally equipped with central processing units, human-machine interfaces and other equipment to monitor and control the various equipment in the substation in real time. The substation is usually equipped with sensors, data acquisition instruments, embedded systems and other equipment to collect and transmit data.

[0043] In summary, the master substation and the substation are different in terms of responsibilities and functions, hierarchical structure and equipment. Although the master substation and the substation are each an independent system, they work closely together and coordinate operations to ensure the stable operation of the substation.

[0044] In a substation, primary equipment and secondary equipment are two equipment concepts.

[0045] Among them, primary equipment refers to high-voltage equipment in substations that is directly connected to the transmission network, mainly including circuit breakers, disconnectors, cables, grounding switches, etc. Among them, circuit breakers are used to open and close circuits to ensure the safe operation of substation equipment; disconnectors are used to isolate cables or electrical equipment for easy maintenance and repair; cables are used to transmit power signals, and grounding switches play the role of electrical grounding or work protection.

[0046] Secondary equipment refers to the equipment connected to the low-voltage side of the substation, mainly including transformers, circuit breakers, intermediate relays, protection devices, metering devices and control devices, etc. Among them, the transformer is mainly used to reduce the voltage, and is also the signal source of the protection and control devices; the circuit breaker is mainly used for switch control, and the protection device is used to protect the safe operation of the primary equipment; the metering device is used to measure and meter the amount of electricity, and the control device is used to control the action of the protection device.

[0047] The difference between primary equipment and secondary equipment is that primary equipment is high-voltage equipment that is in direct contact with the transmission network. Its voltage level is usually higher and it has higher insulation strength and withstand voltage. Secondary equipment is equipment connected to the low-voltage side. Its voltage level is usually lower and it has better control and protection functions.

[0048] In addition, the design, installation and operation of primary and secondary equipment are somewhat different, and different settings and operations are required according to different power system requirements and equipment functions. Therefore, when renovating and expanding the substation, the primary and secondary equipment should be distinguished, and the relevant equipment and facilities should be reasonably configured and deployed to ensure the normal operation of the substation.

[0049] In this embodiment, when the electrical equipment is put into the reconstruction and expansion of the substation as secondary equipment, the substation power grid model file is updated according to the electrical equipment.

[0050] In the specific implementation, the staff can use mobile phones or other tools with scanners to scan the QR code on the electrical equipment at the renovation and expansion site, and transmit the QR code to the substation. Figure 2 As shown, the substation can receive the QR code obtained by scanning the electrical equipment used for renovation and expansion with the barcode scanner, and decode the QR code to obtain the factory identification code and physical ID of the electrical equipment, such as Figure 3 As shown, a relationship table for identifying electrical equipment based on the factory identification code corresponding to the QR code and the physical ID, wherein the relationship table includes the equipment name IEDName, the device identification code and the physical ID.

[0051] Create an account in the OMS (order management system) and write the relationship table into the substation power grid model file.

[0052] For example, Figure 4 As shown in the figure, the structure of the substation power grid model file is as follows:

[0053] (1) File identification level

[0054] The file identification level includes the applicable area Entity, the file data source System, the applicable E language version Version, the file applicable encoding Code, the file version Data, the time Time when the file was generated, etc.

[0055] (2) Regional center level

[0056] The regional center level includes: identifier mRID, region name name, parent region name parent, OMS identifier omsId, operation identifier oflag, operation time oflagTime, etc.

[0057] (3) Substation level

[0058] The substation level includes the identifier mRID, substation name name, standard substation full name with path pathName, highest voltage level voltageLevel, substation type type, OMS identifier omsId, operation identifier oflag, operation time oflagTime, etc.

[0059] (4) Primary equipment model level

[0060] The primary equipment model level includes the identifier mRID, the primary equipment name name, the standard path full name pathName, the type type, the OMS identifier omsId, the physical identifier SWId, the substation identifier substation, the voltage level voltageLevel, the dispatch unit identifier dispatchArea, the operation identifier oflag, the operation time oflagTime, etc.

[0061] (5) Secondary equipment model level

[0062] The secondary equipment model level includes the identifier mRID, secondary equipment name name, standard path full name pathName, manufacturer manufacturer, model model, version type, check code CRC, OMS identifier omsId, physical identifier SWId, IEDName, primary equipment identifier device_one, substation identifier substation, voltage level voltageLevel, dispatch unit identifier dispatchArea, operation identifier oflag, operation time oflagTime, etc.

[0063] Step 102: When the master station senses a change in the substation power grid model file, it generates a secondary equipment online monitoring information description file and a substation management unit remote setting file for the substation and electrical equipment according to the substation power grid model file.

[0064] In the specific implementation, when the substation is renovated or expanded, the substation power grid model file in the control cloud platform is updated. The remote operation and maintenance workstation of the main station perceives the changes in the substation power grid model file in the control cloud platform, and can generate secondary equipment online monitoring information description files and substation management unit remote setting files for the substation and electrical equipment.

[0065] In one embodiment of the present invention, step 102 may include the following steps:

[0066] Step 1021, query the substation for the system configuration file of the entire substation after the reconstruction and expansion.

[0067] In this embodiment, the substation protection team members can be informed of the substation system configuration file after the substation is rebuilt and expanded.

[0068] Step 1022: query the monitoring information configuration description file, the secondary virtual circuit description file and the optical fiber circuit configuration file of the electrical equipment.

[0069] In this embodiment, the substation protection team can be informed to collect the device monitoring information configuration description files and secondary virtual circuit description files of each protection model provided by the secondary equipment manufacturer, and the optical fiber circuit configuration files (or optical cable inventory data) provided by the optical fiber tag manufacturer.

[0070] Step 1023: Update the substation system configuration file according to the electrical equipment in the substation power grid model file.

[0071] In a specific implementation, the substation system configuration file may be updated according to the electrical equipment in the substation power grid model file, so that the substation power grid model file and the substation system configuration file are associated with each other on the electrical equipment.

[0072] In the specific implementation, Figure 5 As shown, the substation power grid model file and the substation full system configuration file are expanded according to the hierarchy; wherein the hierarchy is plant, voltage level, primary equipment and secondary equipment.

[0073] In the expanded substation power grid model file, locate the voltage level to which the electrical equipment belongs as the target level.

[0074] In the expanded substation system configuration file, use the configuration tool to add electrical equipment to the primary equipment at the target level, thereby completing the association configuration of the primary equipment and the secondary equipment between the substation power grid model file and the substation system configuration file.

[0075] Step 1024: If the update is completed, the substation system configuration file, the monitoring information configuration description file, the secondary virtual circuit description file and the optical fiber circuit configuration file are combined into a secondary equipment online monitoring information description file.

[0076] In this embodiment, a configuration tool may be used to combine the substation system configuration file, the monitoring information configuration description file, the secondary virtual circuit description file and the optical fiber circuit configuration file into a secondary equipment online monitoring information description file.

[0077] Step 1025: Generate a remote setting file for the substation management unit according to the secondary equipment online monitoring information description file.

[0078] In this embodiment, a configuration tool may be used to generate a remote setting file of the substation management unit to be configured according to the secondary device online monitoring information description file.

[0079] In a specific implementation, the local online monitoring configuration file may be queried, and the substation management unit remote setting file may be generated using the difference between the secondary device online monitoring information description file and the online monitoring configuration file.

[0080] For example, Figure 6 As shown in the figure, the structure level of the remote setting file of the substation management unit is as follows:

[0088] (4) Homologous object node SamCompDefine

[0089] The homologous object node SamCompDefine contains multiple channel nodes Channel; wherein the Channel node contains a channel type type (01 indicates homologous, 02-switch quantity), and the channel Channel contains multiple device Unit nodes.

[0090] Furthermore, the equipment Unit node includes IEDName, data set reference path, description desc, and belonging data set dsName.

[0100] Step 103: The master station distributes the secondary equipment online monitoring information description file and the slave station management unit remote setting file to the slave station.

[0101] In the specific implementation, the remote operation and maintenance workstation of the main station uses blockchain technology to send the secondary equipment online monitoring information description file and the substation management unit remote setting file to the substation.

[0102] The substation receives the substation renovation and expansion remote maintenance execution file issued by the remote operation and maintenance workstation of the main station, obtains the remotely maintained substation object and the linked remote maintenance file (i.e., the secondary equipment online monitoring information description file and the substation management unit remote setting file) according to the content of the substation renovation and expansion remote maintenance execution file, and completes the issuance of the substation remote maintenance file when the communication status of the substation is normal.

[0103] Generally, the substation can back up the original configuration information of the local system so that it can roll back to the previous configuration when an error occurs during system update.

[0104] Step 104: The substation updates the system according to the secondary equipment online monitoring information description file and the substation management unit remote setting file.

[0105] When receiving the remote execution configuration file command, the substation updates the system according to the secondary equipment online monitoring information description file and the substation management unit remote setting file.

[0106] In a specific implementation, the substation can use a remote operation and maintenance configuration tool to parse the target configuration information required for online monitoring from the secondary equipment online monitoring information description file and the substation management unit remote setting file, thereby upgrading the system according to the target configuration information.

[0107] Exemplarily, the target configuration information includes online monitoring parameter configuration information, alarm configuration information, monitoring and early warning setting configuration information, status quantity configuration information, tripping and closing reverse calibration configuration information, panel indicator light configuration information, back panel configuration information, hard pressure plate configuration information, soft pressure plate configuration information, and the like.

[0108] When the substation completes the system update, the substation conducts a functional acceptance of the updated system; at this time, the protection team in the substation conducts a functional acceptance of the substation renovation and expansion system upgrade item by item according to the acceptance specifications and the substation configuration tools, which includes model acceptance, functional acceptance, data monitoring acceptance, loop acceptance, remote operation acceptance, etc.

[0109] When the functional acceptance is passed, the master station is notified to complete the system update and enable the remote maintenance of the substation. At this time, the substation notifies the master station to complete the system update. When the master station receives the notification that the substation has completed the system update, it completes the model update of the substation according to the original maintenance-free mechanism and completes the remote operation and maintenance process of the entire renovation and expansion.

[0110] If the function acceptance fails, the system will be rolled back to the original configuration information.

[0111] In this embodiment, the substation includes a main station and a substation. When the electrical equipment of the substation is put into renovation and expansion as a secondary equipment, the substation grid model file is updated according to the electrical equipment; when the main station senses the change of the substation grid model file, it generates a secondary equipment online monitoring information description file and a substation management unit remote setting file for the substation and electrical equipment according to the substation grid model file; the main station distributes the secondary equipment online monitoring information description file and the substation management unit remote setting file to the substation; the substation updates the system according to the secondary equipment online monitoring information description file and the substation management unit remote setting file. This embodiment provides a remote operation and maintenance framework for the substation during renovation and expansion, with a high degree of automation, which can greatly reduce the difficulty and complexity of renovation and expansion operation and maintenance, reduce the errors caused by the operation and maintenance personnel modifying the configuration files and the workload and human configuration, and greatly improve the operation and maintenance efficiency of the substation renovation and expansion.
