[0042] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the present invention belongs. "Including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0043] like Figure 1 As shown, an embodiment of the present invention provides a method for automatically generating a secondary circuit safety measure list, the method comprising steps S101 to S103, wherein:

[0044] Step S101: constructing safety measures rules related to the secondary circuit, wherein the safety measures rules include safety measures implementation sequence rules, secondary safety measures rules for opening and closing circuits, secondary safety measures rules for current circuits, and secondary safety measures rules for voltage circuits;

[0045] It should be noted that the safety measures rules constructed are as follows:

[0046] 1. The implementation order of secondary security measures should follow the following principles

[0047] 1) Confirm the position of the soft pressure plate (only executed by the intelligent station);

[0048] 2) Isolate the output and input circuits;

[0049] 3) Isolate the current loop;

[0050] 4) Isolation voltage circuit;

[0051] 5) Isolate signal circuit;

[0052] 6) Isolate AC and DC power supply circuits;

[0053] 7) Put the hard pressure plate into maintenance (only executed at the smart station).

[0054] 2. Secondary safety measures for opening and closing circuits should follow the following principles

[0055] 1) For the first maintenance after the new installation and commissioning of conventional station protection, the isolation of the open circuit from the maintenance equipment to the operating equipment should be implemented at the relevant operating panel cabinet, and other types of maintenance should be implemented at the maintenance panel cabinet.

[0056] 2) For new installation and maintenance of conventional stations, isolation of the incoming circuits from operating equipment to maintenance equipment should be implemented at the relevant operating panel cabinets. The first maintenance after commissioning can be implemented in accordance with the maintenance of new installations. Isolation of the incoming circuits for other types of maintenance is not required.

[0057] 3) For intelligent station protection and maintenance, GOOSE direct jump and network jump optical fiber isolation should be implemented in the maintenance panel cabinet.

[0058] 4) For tripping, starting failure, joint tripping, etc., the outgoing and incoming circuits should be isolated. A group of secondary circuits in a conventional station should be completely isolated, and a group of receiving and transmitting optical fibers in an intelligent station should be completely unplugged.

[0059] 5) During line interval maintenance, the optical fiber (high frequency) channel of the line protection device should be reliably isolated.

[0060] 3. Secondary safety measures for current loops should follow the following principles

[0061] 1) For new installations, first inspections and routine inspections after commissioning of single-bay or single-circuit breaker protection with independent current winding connection, the current circuit isolation of conventional stations should be implemented at the affected busbar protection, safety devices and other operating cabinets (collectively referred to as public protection): the intelligent station should confirm that the SV receiving soft pressure plate of the corresponding maintenance bay has been withdrawn in the affected operating equipment.

[0062] 2) For single-bay or single-circuit breaker protection with 3 / 2 circuit breaker wiring, bridge wiring and other current connection methods, the current circuit isolation should be implemented at the affected operation panel cabinet during the new installation, the first maintenance after commissioning and routine maintenance. If conditions are not met, it can be implemented at the switch field terminal box. The current circuit isolation of the current connection method should be carried out by opening the connecting piece.

[0063] 3) For non-stop protection of primary equipment, for new installations and the first maintenance after commissioning, the isolation of the dedicated current circuit of conventional stations should be implemented at the switch yard terminal box, and the isolation of the series current circuit should be implemented at the upper-level operating cabinet: the direct current and network optical fiber isolation of smart stations should be implemented at the maintenance cabinet.

[0064] 4) Protection failure elimination or upgrade of primary equipment without power outage, routine maintenance of public protection. Conventional station current circuit isolation should be implemented at the maintenance cabinet: Intelligent station current direct network optical fiber isolation should be implemented at the maintenance cabinet. If the current circuit is connected in series with other operating equipment, the affected operating equipment should be withdrawn in principle. If it cannot be withdrawn, the relevant current circuit should be jumpered or short-circuited at the maintenance cabinet.

[0065] 5) Before and after the current circuit is bridged or short-circuited, the current sampling of the running equipment should be checked to see if it is consistent with the actual situation. Only after confirmation can the connection of the relevant current circuit of the maintenance equipment be opened.

[0066] 6) When the secondary safety measures are implemented, the operating current circuit must not lose grounding, otherwise temporary grounding should be added and the temporary grounding should be removed immediately after the permanent grounding is restored.

[0067] 4. The secondary safety measures for voltage circuits should follow the following principles

[0068] 1. For new installation and maintenance of conventional station protection, voltage circuit isolation should be implemented at the source end such as the voltage parallel panel and the switch field voltage transformer terminal box. The first maintenance after commissioning should be implemented in accordance with the maintenance of new installations. Other types of maintenance should be carried out before the voltage switching circuit of the maintenance panel cabinet.

[0069] 2. For intelligent station protection and maintenance, direct voltage sampling, network sampling, and cascaded optical fiber isolation should be implemented at the maintenance panel cabinet.

[0070] Step S102: classifying all secondary circuits involved according to the safety measure rules to obtain multiple circuit type names, and defining corresponding determination conditions for the multiple circuit type names respectively;

[0071] In this step, please refer to Table 1 below. The classification types and judgment conditions of the secondary circuit are as follows:

[0072] Table 1 Circuit type classification and judgment conditions

[0073]

[0074]

[0075] The installation rules are described according to the configuration file, and the installation rules for each type of interval, each type of cabinet, and each type of device are described, thereby supporting automatic finding of the installation object according to the configuration file.

[0076] The establishment of a common secondary circuit safety measure object search method also helps improve efficiency. Through pre-defined logical rules, the automatic generation tool can quickly perform the search task, reduce the need for manual input, reduce the possibility of errors, and speed up the generation process of safety measure sheets. To achieve this, it is necessary to conduct a detailed analysis of different types of circuits and establish a complete set of rules.

[0077] Ultimately, this approach not only improves work efficiency, but also improves design quality. Through precise customization of safety measures, operational risks can be reduced, accidents can be prevented, and the safety and reliability of substation operations can be fundamentally improved. Therefore, establishing universal safety measures and specific search logic based on each circuit is a key step in achieving efficient and accurate automatic generation of secondary circuit safety measures.

[0078] In addition, in some embodiments, there are many types of secondary circuits in the substation, including but not limited to protection circuits, control circuits, measurement circuits, etc. Each circuit has its own specific functions and safety requirements. For example, the protection circuit needs to ensure that the circuit can be quickly disconnected in the event of a fault, while the control circuit needs to ensure the accurate transmission of the operating signal. Therefore, each circuit requires specific safety measures to deal with possible risks.

[0079] Second, the generic safety object lookup logic allows us to establish a basic framework for parsing and applying safety measures common to all circuits. The existence of this logic ensures that all circuits meet at least a basic safety standard when designed. However, relying solely on generic logic is not enough, as it may ignore the special safety requirements of some specific circuits.

[0080] This ensures that the uniqueness of each circuit is taken into account during the design, ensuring the meticulousness and accuracy of the safety measures list. For example, for a high-voltage protection circuit, special isolation measures and a faster response mechanism may be required; while for a control circuit, more attention may be paid to signal continuity and reliability.

[0081] According to the secondary safety measures steps and safety measures principles, all secondary circuits are classified into circuits: DC power supply circuit: ZL (terminal block terminal); AC power supply circuit: JL (terminal block terminal); AC current circuit: JDL (terminal block terminal); AC voltage circuit: JDY (terminal block terminal); DC current circuit: ZDL (terminal block terminal); DC voltage circuit: ZDY (terminal block terminal); hard pressure plate: YYB (general hard pressure plate rule); functional soft pressure plate: GNRYB (functional soft pressure plate for non-virtual circuit reception and transmission); GOOSE sending soft pressure plate: GFYB (virtual circuit reception and transmission soft pressure plate); GOOSE receiving soft pressure plate: GSYB (virtual circuit reception and transmission soft pressure plate); SV receiving soft pressure plate: SSYB (virtual circuit reception and transmission soft pressure plate); Soft pressure plate); optical fiber: GX (optical port); longitudinal differential channel: ZC (optical port); open-in circuit: KR (terminal block terminal); open-out circuit: KC (terminal block terminal); remote control circuit: YK (terminal block terminal); trip circuit: TZ (terminal block terminal); failure circuit: SL (terminal block terminal); re-pressure locking circuit: FYBS (terminal block terminal); function locking circuit: GNBS (terminal block terminal); overload air cooling circuit: GFH (terminal block terminal); signal circuit: XH (terminal block terminal); measurement and control signal circuit: CKXH (terminal block terminal); fault recording signal circuit: LBXH (terminal block terminal); timing: DS (terminal block terminal, device backplane terminal, device backplane optical port); others: QT.

[0082] Step S103: Analyze each type of secondary circuit one by one to obtain the objects that need to take safety measures according to the analysis results, classify, mark and allocate each analyzed object to the corresponding cabinet and circuit to obtain a safety measure ticket.

[0083] It should be noted that in substation project management, data collation and visualization of secondary circuit safety measure objects are key steps, which are directly related to the safety and accuracy of on-site operations. The following will describe in detail how to parse the safety measure objects of each circuit according to the general safety measure object search logic, perform data collation, and how to mark on the secondary circuit connection diagram of the panel cabinet and automatically generate safety measure tickets.

[0084] First, it is necessary to analyze each type of secondary circuit one by one according to the pre-established general safety measure object search logic. Through the automated tool to scan the design drawings and related data, all objects that may need safety measures are parsed. These objects include but are not limited to circuit breakers, disconnectors, transformers, relays, etc. In this process, each object must be classified and coded according to the panel cabinet, bay, circuit type and specific location to which it belongs.

[0085] Data collation is the process of organizing the initially parsed safety measures objects into useful information. This requires the use of software tools to classify, label and assign each parsed object to the corresponding cabinets and circuits. For example, all circuit breakers, grounding switches, measuring devices, etc. belonging to the same cabinet should be grouped together and further subdivided according to their role in the circuit.

[0086] Each object should be given a unique identifier and its precise location in the panel cabinet recorded. This information is then entered into a database to create a comprehensive and detailed list of safety measure objects. During the compilation process, missing information or inconsistent data may be found, which must be resolved in a timely manner. This may involve communication with design engineers, field technicians or project managers and updating database records.

[0087] Visualizing the collated and checked data is a key step in clearly presenting safety measures to operators. Use professional software or customized visualization tools to mark each safety measure object on the secondary circuit connection diagram of the panel cabinet, and use different colors or graphics to identify different types of safety measures. For example, red can be used to identify circuit breaking operations, green for grounding, and blue for equipment that needs to be locked or tagged.

[0088] In addition, the execution sequence of safety measures can be shown on the diagram, such as by using arrows to indicate the flow of operations. The graphical display must be intuitive and easy to understand to help on-site personnel quickly locate the safety measure object and understand how to perform the required safety operations step by step.

[0089] The automatic generation of safety measures tickets is the final product of the entire process. This requires an automated system that integrates databases, CAD systems, and document generation tools. The system automatically fills in the safety measures ticket template in a preset format based on the collated and verified data and the visual secondary circuit connection diagram of the panel cabinet. The generated safety measures ticket will include the following information:

[0090] 1. Detailed description and location of the object of the security measure;

[0091] 2. The specific steps required to implement each safety measure;

[0092] 3. Relevant graphic identification and serial number guide operators to find the corresponding equipment on the secondary circuit connection diagram;

[0093] 4. Precautions and warnings to prevent possible safety risks;

[0094] 5. The signature column of the executor and supervisor ensures clear responsibilities.

[0095] In addition, in some embodiments, the security measure execution location and security measure execution strategy are retrieved from a preset database according to the analysis results, and a security measure ticket is generated according to the security measure execution location and security measure execution strategy.

[0096] For example, if the input and output circuits are isolated, then:

[0097] The place where the safety measures are implemented is: the relevant operation screen (not the measurement and control recording screen). If it is line protection, the operation screen of the optical fiber (high frequency) channel of the line protection device is on the line protection maintenance screen.

[0098] The implementation strategy of the safety measures is: 1. Unlock the input and output terminals of the non-measurement, control and recording related operation screen; unlock the "panel cabinet / terminal box name + terminal number + number tube number + (function)" loop, and wrap it with red insulating tape. Example: Unlock the DI3 remote trip input loop on the 220kV line optical differential protection cabinet 1-21QD3. 2. Unplug the longitudinal differential channel of the line protection device. During line interval maintenance, the optical fiber (high frequency) channel of the line protection device should be reliably isolated: unplug the "panel cabinet / terminal box name + device name + plug-in number + optical port + label number + (function)" optical fiber and cover it with a dust cap. Example: Unplug the optical fiber of the 220kV line optical differential protection cabinet 1-1n line protection device 05 plug-in TX1 optical fiber channel interface 1 optical fiber. (The longitudinal differential fiber has no opposite end cabinet, and the label number information is only half), 1-3n-B07-RX1 / JHJ04(ZW A)→JHJ04-TX6(5063-G138A).

[0099] The object lookup method is:

[0100] 1. By traversing all cables, find the cable with a maintenance cabinet at one end and only at one end in the startCubicle and endCubicle. If this cable has a maintenance cabinet at one end and an operation cabinet associated with it at the other end;

[0105] 6. Based on the connection line Core and the corresponding Point found in steps 4 and 5, output the operation items for opening and closing the loop, as follows:

[0106] 6.1. Cabinet / terminal box name = this running cabinet Cubicle.Name;

[0107] 6.2.Terminal number=Point.DeviceName+Point.SubdeviceName;

[0110] 7. In the maintenance screen, traverse the interfaces where Cubicle.FunctionArea.Interface.class = Communication and Cubicle.FunctionArea.Interface.type = HLDC, as follows:

[0112] 7.2. Device name = Point.DeviceName + Device.desc of the device with the same name on the same screen;

[0113] 7.3.Plugin number = Point.SubdeviceName;

[0114] 7.4.Optical port = Point.pinName;

[0115] 7.5. Tag number = Point.DeviceName-Point.SubdeviceName-Point.pinName / Cable.StartCubicle——Point.DeviceName-Point.SubdeviceName-Point.pinName / Cable.endCubicle

[0116] Function = Interface.desc.

[0125] No power outage: 1. Short-circuit the terminals on the operating panel side that are connected to the maintenance panel.
