[0035] The equipment control commands are sent in parallel to the corresponding substation equipment terminals, so that each substation equipment terminal performs corresponding equipment control processing based on the equipment control commands, and returns the equipment control results of each substation equipment terminal to the power supply dispatch terminal.

[0036] When the equipment control results at each of the aforementioned power equipment terminals meet the preset conditions, the grounding control command is sent in parallel to the corresponding grounding terminal, so that each of the grounding terminals performs the corresponding grounding control processing based on the grounding control command, and returns the grounding control result of each of the grounding terminals to the power supply dispatch terminal;

[0037] The equipment control results and the grounding control results are input into a pre-built state verification model to obtain the state verification results corresponding to the skylight operation section; the state verification results are used to indicate whether the skylight operation section meets the preset operation conditions.

[0039] Fourthly, this application also provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, performs the following steps:

[0040] In response to the operation instruction for the track maintenance section of the power supply dispatch terminal, a parallel control instruction package corresponding to the track maintenance section is generated; the parallel control instruction package includes the equipment control instruction of the substation equipment terminal corresponding to the power supply dispatch terminal, and the grounding control instruction of the grounding terminal corresponding to the power supply dispatch terminal.

[0041] The equipment control commands are sent in parallel to the corresponding substation equipment terminals, so that each substation equipment terminal performs corresponding equipment control processing based on the equipment control commands, and returns the equipment control results of each substation equipment terminal to the power supply dispatch terminal.

[0042] When the equipment control results at each of the aforementioned power equipment terminals meet the preset conditions, the grounding control command is sent in parallel to the corresponding grounding terminal, so that each of the grounding terminals performs the corresponding grounding control processing based on the grounding control command, and returns the grounding control result of each of the grounding terminals to the power supply dispatch terminal;

[0043] The equipment control results and the grounding control results are input into a pre-built state verification model to obtain the state verification results corresponding to the skylight operation section; the state verification results are used to indicate whether the skylight operation section meets the preset operation conditions.

[0044] Based on the status verification results, the skylight operation section is processed accordingly.

[0045] Fifthly, this application also provides a computer program product, including a computer program that, when executed by a processor, performs the following steps:

[0046] In response to the operation instruction for the track maintenance section of the power supply dispatch terminal, a parallel control instruction package corresponding to the track maintenance section is generated; the parallel control instruction package includes the equipment control instruction of the substation equipment terminal corresponding to the power supply dispatch terminal, and the grounding control instruction of the grounding terminal corresponding to the power supply dispatch terminal.

[0047] The equipment control commands are sent in parallel to the corresponding substation equipment terminals, so that each substation equipment terminal performs corresponding equipment control processing based on the equipment control commands, and returns the equipment control results of each substation equipment terminal to the power supply dispatch terminal.

[0048] When the equipment control results at each of the aforementioned power equipment terminals meet the preset conditions, the grounding control command is sent in parallel to the corresponding grounding terminal, so that each of the grounding terminals performs the corresponding grounding control processing based on the grounding control command, and returns the grounding control result of each of the grounding terminals to the power supply dispatch terminal;

[0049] The equipment control results and the grounding control results are input into a pre-built state verification model to obtain the state verification results corresponding to the skylight operation section; the state verification results are used to indicate whether the skylight operation section meets the preset operation conditions.

[0050] Based on the status verification results, the skylight operation section is processed accordingly.

[0051] The aforementioned distributed collaborative control method, device, computer equipment, storage medium, and computer program product for railway power supply maintenance windows based on the SCADA system first responds to the operation instructions for the maintenance window section from the power supply dispatching end, generating a parallel control instruction package corresponding to the maintenance window section. The parallel control instruction package includes equipment control instructions for the substation equipment corresponding to the power supply dispatching end, and grounding control instructions for the grounding terminal corresponding to the power supply dispatching end. Then, the equipment control instructions are sent in parallel to the corresponding substation equipment, enabling each substation equipment to perform corresponding equipment control processing based on the equipment control instructions, and returning the results to each substation equipment. The equipment control results are sent to the power supply dispatching terminal. If the equipment control results at each substation terminal meet the preset conditions, grounding control commands are sent in parallel to the corresponding grounding terminals. Each grounding terminal then performs the corresponding grounding control processing based on the grounding control commands and returns the grounding control results to the power supply dispatching terminal. Next, the equipment control results and grounding control results are input into a pre-built state verification model to obtain the state verification results for the track maintenance window section. The state verification results indicate whether the track maintenance window section meets the preset operating conditions. Finally, based on the state verification results, the track maintenance window section is processed accordingly. In this way, during track maintenance operations, a parallel control command package containing both substation control and grounding control commands is generated in response to the track maintenance operation instructions. These two types of control commands are then sent to the substation equipment end and the grounding terminal in parallel. The two types of control commands are carried out synchronously according to the process, which shortens the time spent on issuing various commands and handling them on-site. Then, based on the pre-built status verification model, the control results fed back from both ends are automatically summarized and the section operation conditions are quickly verified. Based on the verification results, the subsequent section operation is carried out in real time. This avoids the shortcomings of the traditional technology, which uses a serial step-by-step processing method, requiring each item, each station, and each grounding switch to be completed sequentially in the track maintenance operation, which is time-consuming and results in low efficiency. This improves the efficiency of track maintenance operations. Attached Figure Description

[0060] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0061] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, data stored, data displayed, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of the relevant data must comply with relevant regulations.

[0062] The distributed collaborative control method for railway power supply maintenance during track openings based on SCADA systems provided in this application can be applied to, for example... Figure 1 In the application environment shown, the power supply dispatching terminal 102 communicates with the substation equipment terminal 104 and the grounding terminal 106 via a network. Specifically, refer to... Figure 1 In response to the operation command for the maintenance window section of the power supply dispatching terminal 102, the power supply dispatching terminal 102 generates a parallel control command package corresponding to the maintenance window section. The parallel control command package includes equipment control commands for the substation equipment terminal 104 corresponding to the power supply dispatching terminal 102, and grounding control commands for the grounding terminal 106 corresponding to the power supply dispatching terminal 102. The equipment control commands are sent in parallel to the corresponding substation equipment terminal 104, so that each substation equipment terminal 104 performs corresponding equipment control processing based on the equipment control commands, and returns the equipment control results of each substation equipment terminal 104 to the power supply dispatching terminal 102. When the equipment control results at the substation equipment end 104 all meet the preset conditions, grounding control commands are sent in parallel to the corresponding grounding terminals 106. Each grounding terminal 106 then performs corresponding grounding control processing based on the grounding control commands and returns the grounding control results from each grounding terminal 106 to the power supply dispatching end 102. The equipment control results and grounding control results are input into a pre-built state verification model to obtain the state verification results for the maintenance window section. The state verification results indicate whether the maintenance window section meets the preset operating conditions. Based on the state verification results, the maintenance window section is processed accordingly. The power supply dispatching end 102 refers to the server of the dispatching master station equipped with the SCADA system, used for generating command packets, issuing commands, summarizing data, and performing state verification. The substation equipment end 104 refers to the edge measurement and control unit deployed at the substation corresponding to the dispatching master station. The grounding terminal 106 refers to the terminal deployed in the overhead contact line maintenance section. The terminal can be, but is not limited to, various personal computers, laptops, smartphones, and tablets; the server can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services.

[0063] In one exemplary embodiment, such as Figure 2 As shown, a distributed collaborative control method for railway power supply maintenance during track openings based on a SCADA system is provided, and this method is applied to... Figure 1Taking the power supply dispatch terminal as an example, this embodiment of the method includes the following steps:

[0064] Step S201: In response to the operation instruction for the track maintenance section of the power supply dispatching terminal, generate a parallel control instruction package corresponding to the track maintenance section; the parallel control instruction package includes the equipment control instruction of the substation equipment terminal corresponding to the power supply dispatching terminal, and the grounding control instruction of the grounding terminal corresponding to the power supply dispatching terminal.

[0065] Among them, the track maintenance window section refers to the section of the railway catenary that needs to be maintained during the track maintenance window period.

[0066] Among them, the work instruction refers to the power outage maintenance start instruction corresponding to the track maintenance window section.

[0067] Among them, the parallel control instruction package refers to a set of instructions that includes equipment control instructions and grounding control instructions.

[0068] Among them, equipment control commands refer to remote control commands issued to the substation equipment end, which are used to control the circuit breaker to open, the disconnecting switch to open, and the feeder operating power supply to disconnect the substation side to realize the power outage operation.

[0069] Among them, the grounding control command refers to the enable command issued to the grounding terminal (which does not directly drive the grounding to close), and is used to adjust the enable flag bit of the grounding terminal.

[0070] For example, the power supply dispatching terminal receives a work instruction for a track maintenance window section of the power supply dispatching terminal, and performs integrity verification processing on the work instruction to obtain the integrity verification result of the work instruction; if the integrity verification result indicates that the work instruction has passed the verification; in response to the work instruction, it generates equipment control instructions for the substation equipment end corresponding to the power supply dispatching terminal and grounding control instructions for the grounding terminal corresponding to the power supply dispatching terminal, as parallel control instruction packets corresponding to the track maintenance window section.

[0071] Step S202: Parallel equipment control commands are sent to the corresponding substation equipment terminals, enabling each substation equipment terminal to perform corresponding equipment control processing based on the equipment control commands, and the equipment control results of each substation equipment terminal are returned to the power supply dispatch terminal.

[0072] Among them, the equipment control result refers to the feedback data sent back to the power supply dispatching end after the power equipment performs equipment control processing, including equipment execution status, fault and abnormality indicators, etc.

[0073] For example, after the power supply dispatching terminal completes the parsing and verification of the equipment control commands, it sends the equipment control commands to the corresponding substation equipment terminals in parallel, so that each substation equipment terminal performs circuit breaker tripping, disconnection switch disconnection and operation power disconnection based on the equipment control commands, obtains the equipment control results of the substation equipment terminals, and returns the equipment control results of each substation equipment terminal to the power supply dispatching terminal.

[0074] Step S203: When the equipment control results at each substation end meet the preset conditions, grounding control commands are sent in parallel to the corresponding grounding terminals, so that each grounding terminal performs the corresponding grounding control processing based on the grounding control commands, and the grounding control results of each grounding terminal are returned to the power supply dispatching end.

[0075] Among them, the preset conditions refer to the pre-set qualification criteria for substation power outage operations, which are used to indicate that all substation equipment in the track maintenance section has completed the circuit breaker tripping, disconnecting switch disconnection and operation power disconnection in the preset power outage sequence.

[0076] Among them, the grounding control result refers to the feedback data sent back to the power supply dispatching terminal after the grounding terminal performs grounding control processing, including local voltage test data, grounding interlocking verification status, grounding mechanism operation completion status, abnormal fault indicators, etc.

[0077] For example, the power supply dispatch terminal receives and summarizes the equipment control results transmitted from each substation in real time. When all substations in the maintenance window section have completed the circuit breaker tripping, disconnecting switch disconnection, and operation power disconnection according to the preset power outage sequence, the terminal issues grounding control commands to the corresponding grounding terminals in parallel. This enables each grounding terminal to receive the commands synchronously and then autonomously start the voltage testing process. The terminal collects the contact network line voltage data in real time and determines the line's energized status. Under the premise that the voltage testing confirms that there is no residual voltage on the line and that the grounding operation specifications are met, the terminal automatically performs the grounding closing operation. After the grounding operation is completed, the terminal generates grounding control results containing the voltage testing results, grounding status, and operation anomaly information, and returns the grounding control results of each grounding terminal to the power supply dispatch terminal.

[0078] Step S204: Input the equipment control results and grounding control results into the pre-built state verification model to obtain the state verification results corresponding to the skylight operation section; the state verification results are used to indicate whether the skylight operation section meets the preset operation conditions.

[0079] Among them, the state verification model, also known as the global state verification function, refers to a data comparison model deployed at the power supply dispatching terminal based on preset judgment logic.

[0080] Among them, the preset working conditions refer to the pre-configured working conditions for the track maintenance window, such as all substations corresponding to the track maintenance window section being de-energized, and the grounding work corresponding to the track maintenance window section being completed.

[0081] For example, the power supply dispatching terminal inputs the equipment control results and grounding control results into a pre-built state verification model. Based on the judgment rules of the preset operating conditions, the pre-built state verification model compares the equipment control results and grounding control results to obtain the state verification results corresponding to the track maintenance window section. The state verification results are used to indicate whether the track maintenance window section meets the preset operating conditions.

[0082] Step S205: Based on the status verification results, perform corresponding processing on the skylight operation section.

[0083] For example, the power supply dispatching terminal queries the pre-defined correspondence between the status verification results and the section processing methods based on the status verification results, and obtains the section processing method corresponding to the status verification results as the target section processing method for the track maintenance window section; then, the track maintenance window section is processed accordingly according to the target section processing method.

[0084] In the aforementioned distributed collaborative control method for railway power supply maintenance window operations based on the SCADA system, the following steps are taken: First, in response to the operation instructions for the maintenance window section issued by the power supply dispatching end, a parallel control instruction package corresponding to the maintenance window section is generated. This package includes equipment control instructions for the substation equipment corresponding to the power supply dispatching end, and grounding control instructions for the grounding terminal corresponding to the power supply dispatching end. Then, the equipment control instructions are sent in parallel to the corresponding substation equipment, enabling each substation equipment to perform corresponding equipment control processing based on the instructions, and returning the equipment control results to the power supply dispatching end. If the equipment control results of each substation equipment meet preset conditions, grounding control instructions are sent in parallel to the corresponding grounding terminals, enabling each grounding terminal to perform corresponding grounding control processing based on the instructions, and returning the grounding control results to the power supply dispatching end. Next, the equipment control results and grounding control results are input into a pre-built state verification model to obtain the state verification results corresponding to the maintenance window section. The state verification results indicate whether the maintenance window section meets the preset operation conditions. Finally, the maintenance window section is processed accordingly based on the state verification results. In this way, during track maintenance operations, a parallel control command package containing both substation control and grounding control commands is generated in response to the track maintenance operation instructions. These two types of control commands are then sent to the substation equipment end and the grounding terminal in parallel. The two types of control commands are carried out synchronously according to the process, which shortens the time spent on issuing various commands and handling them on-site. Then, based on the pre-built status verification model, the control results fed back from both ends are automatically summarized and the section operation conditions are quickly verified. Based on the verification results, the subsequent section operation is carried out in real time. This avoids the shortcomings of the traditional technology, which uses a serial step-by-step processing method, requiring each item, each station, and each grounding switch to be completed sequentially in the track maintenance operation, which is time-consuming and results in low efficiency. This improves the efficiency of track maintenance operations.

[0085] In an exemplary embodiment, step S201 above, in response to the operation command for the maintenance window section of the power supply dispatching terminal, generates a parallel control command package corresponding to the maintenance window section, specifically including the following: determining candidate substation terminals and candidate grounding terminals associated with the power supply dispatching terminal; in response to the operation command for the maintenance window section of the power supply dispatching terminal, determining the candidate substation terminal located in the maintenance window section from each candidate substation terminal as the substation terminal, and determining the candidate grounding terminal located in the maintenance window section from each candidate grounding terminal as the grounding terminal; generating equipment control commands for the substation terminal corresponding to the power supply dispatching terminal and grounding control commands for the grounding terminal corresponding to the power supply dispatching terminal; and obtaining a parallel control command package corresponding to the maintenance window section based on the equipment control commands and grounding control commands.

[0086] Among them, candidate substation terminals are used to represent all substation terminals within the geographical jurisdiction of the power supply dispatching terminal.

[0087] Among them, candidate grounding terminals are used to represent all grounding terminals within the geographical jurisdiction of the power supply dispatching terminal.

[0088] For example, the power supply dispatching terminal obtains the topology file corresponding to itself and inputs it into the trained information determination model. The trained model then identifies candidate substation terminals and candidate grounding terminals associated with the power supply dispatching terminal. The topology file represents the topological connections between the power supply dispatching terminal, candidate substation terminals, and candidate grounding terminals. Next, the geographical locations of the candidate substation terminals and candidate grounding terminals are obtained. Then, in response to the work instructions for the power supply dispatching terminal's designated work window section, candidate substation terminals with corresponding geographical locations within the work window section are identified from among the candidate substation terminals, and candidate grounding terminals with corresponding geographical locations within the work window section are identified from among the candidate grounding terminals, and designated as grounding terminals. Next, based on the work instructions and the identification information of the substation terminals, equipment control instructions for the substation terminals corresponding to the power supply dispatching terminal are generated, and grounding control instructions for the grounding terminals corresponding to the power supply dispatching terminal are generated based on the work instructions and the identification information of the grounding terminals. Finally, the equipment control instructions and grounding control instructions are encapsulated and integrated to obtain a parallel control instruction package corresponding to the work window section.

[0089] In this embodiment, after receiving the maintenance window instruction, the controlled equipment corresponding to the section is accurately selected as needed and then packaged into a parallel instruction package, thereby quickly locking the control points required for the operation, avoiding irrelevant equipment from issuing instructions by mistake, and relying on the parallel instructions to distribute instructions to the substation and the field grounding terminal at the same time, shortening the overall time of power outage grounding, which is conducive to improving the efficiency of maintenance window operations.

[0090] In an exemplary embodiment, the equipment control commands include a first disconnect command corresponding to a circuit breaker at the substation end, a second disconnect command corresponding to a disconnecting switch, and a power disconnect command for the operating power supply at the substation end. The substation end is further configured to disconnect the circuit breaker according to the first disconnect command; disconnect the disconnecting switch according to the second disconnect command after all circuit breakers have been disconnected; and disconnect the operating power supply according to the power disconnect command after all disconnecting switches have been disconnected. Here, a circuit breaker refers to a high-voltage switchgear in a substation used to connect or disconnect the overhead contact line power supply circuit.

[0091] The first disconnection command refers to the control command used to control the circuit breaker to perform the tripping operation.

[0092] Wherein, the disconnector refers to the supporting switchgear in the traction substation.

[0093] Wherein, the second disconnection instruction refers to a control instruction for driving the disconnector to perform the opening operation.

[0094] Wherein, the operating power supply is a power supply circuit that provides power energy for the electric operating mechanisms of the circuit breaker and the disconnector.

[0095] Wherein, the power supply disconnection instruction refers to a control instruction for disconnecting the operating power supply.

[0096] Exemplarily, the substation equipment side performs disconnection processing on the circuit breaker according to the first disconnection instruction, collects the position signal of the circuit breaker, and determines the opening state of the circuit breaker based on the position signal; under the condition that the opening state of each circuit breaker indicates that the disconnection is completed, the disconnection processing is performed on the disconnector according to the second disconnection instruction, and the position change information of the disconnector is collected; under the condition that the position change information of each disconnector indicates that the disconnection is completed, the operating power supply is disconnected according to the power supply disconnection instruction.

[0097] In this embodiment, the substation equipment side executes the operations step by step strictly in the sequence of circuit breaker disconnection, disconnector disconnection, and operating power supply disconnection, which conforms to the safety regulations for traction power supply switching operations, can effectively prevent the malignant misoperation of pulling the disconnector with load, and fully guarantee the operation standardization of the skylight power outage operation and the operation safety of the power supply system.

[0098] In an exemplary embodiment, the grounding terminal is further configured to generate a power inspection instruction corresponding to the grounding terminal in response to the grounding control instruction, perform corresponding power inspection processing according to the power inspection instruction, and perform corresponding grounding control processing according to the grounding control instruction under the condition that the power inspection result meets the preset power inspection result.

[0099] Wherein, the power inspection instruction refers to a control instruction for detecting the live voltage of the catenary line corresponding to the grounding terminal.

[0100] Wherein, the power inspection result refers to the measured data of the catenary voltage, including the instantaneous voltage value and the live state of the catenary voltage.

[0101] Wherein, the preset power inspection result refers to a pre-set power inspection criterion, which includes that the instantaneous voltage value of the catenary voltage is lower than the preset voltage threshold, and the live state is a no-power state.

[0102] For example, in response to the grounding control command, the grounding terminal generates a corresponding voltage testing command based on the terminal number, voltage testing sampling duration, and voltage acquisition range parameters, and performs corresponding voltage testing processing according to the voltage testing command; if the voltage testing result meets the preset voltage testing result, the grounding switch of the grounding terminal is driven to perform a closing grounding operation according to the grounding control command; if the voltage testing result does not meet the preset voltage testing result, an abnormal alarm message of the grounding terminal is generated and returned to the power supply dispatching terminal.

[0103] In this embodiment, after receiving the grounding control command, the grounding terminal first performs a voltage test. The grounding operation is only performed when the voltage test result meets the preset voltage test result. This can realize live interlocking from the equipment end, eliminate the major safety hazard of forcibly closing the circuit to ground while the line is energized, avoid short circuit accidents, and help improve the safety and standardization of the operation process of the grounding operation during the skylight.

[0104] In an exemplary embodiment, step S204 above, which inputs the equipment control results and grounding control results into a pre-built state verification model to obtain the state verification results corresponding to the skylight operation section, specifically includes the following: performing fusion processing on the equipment control results and grounding control results to obtain fused control results; inputting the fused control results into the pre-built state verification model to obtain the state verification results corresponding to the skylight operation section.

[0105] Among them, the integrated control result refers to the comprehensive control result formed by summarizing and integrating the data and fields of the equipment control result and the grounding control result.

[0106] For example, the power dispatching terminal inputs the equipment control results and grounding control results into the trained importance prediction model to obtain the first importance of the equipment control results and the second importance of the grounding control results. Then, from each equipment control result, the equipment control results with the first importance greater than the preset importance are selected as key equipment control results, and from each grounding control result, the grounding control results with the second importance greater than the preset importance are selected as key grounding control results. Then, the key equipment control results and key grounding control results are aggregated and their fields are integrated to obtain the fused control results. Next, the fused control results are input into the pre-built state verification model. Based on the preset operation conditions judgment rules, the pre-built state verification model compares the fused control results to obtain the state verification results corresponding to the track maintenance section.

[0107] In this embodiment, the equipment control results and grounding control results are fused into an integrated fused control result, which is then sent to the status verification model for unified verification. This avoids the problems of information fragmentation, omissions and misjudgments caused by verifying the two types of data separately. It also makes it easier for the model to comprehensively check the overall working conditions of the section power outage and grounding, and improves the comprehensiveness and accuracy of the verification of the conditions for starting the maintenance window.

[0108] In an exemplary embodiment, step S205 above, which involves processing the skylight operation section according to the status verification result, specifically includes the following: if the status verification result indicates that the skylight operation section meets the preset operation conditions, the skylight operation section is processed according to the operation instruction; if the status verification result indicates that the skylight operation section does not meet the preset operation conditions, fault alarm information corresponding to the skylight operation section is generated, and fault alarm processing is performed on the skylight operation section according to the fault alarm information.

[0109] Among them, fault alarm information refers to the prompt data that records the section of track maintenance that does not meet the preset operation conditions. It includes the abnormal equipment number, equipment type (power equipment end / grounding terminal), abnormal cause (circuit breaker not tripped, control power supply not disconnected, voltage test energized, grounding not closed, etc.), abnormal location, and fault occurrence time.

[0110] For example, when the status verification result indicates that the maintenance section meets the preset operating conditions, the power supply dispatching terminal extracts the corresponding overhead contact line maintenance instruction and equipment maintenance instruction from the operating instructions, and performs overhead contact line maintenance and equipment maintenance on the maintenance section according to the overhead contact line maintenance instruction and equipment maintenance instruction; when the status verification result indicates that the maintenance section does not meet the preset operating conditions, the terminal generates the corresponding fault alarm information for the maintenance section based on the abnormal equipment number, fault location, fault type and time of occurrence of the abnormality, and performs fault alarm processing on the maintenance section according to the fault alarm information, so as to stop the operation of the maintenance section.

[0111] In this embodiment, the control logic is executed in two separate paths based on the status verification results, thereby avoiding the safety risks of illegal commencement of work on energized lines from the source, facilitating quick investigation and rectification by maintenance personnel, and realizing intelligent control of skylight operation approval, taking into account both operational safety and fault handling efficiency.

[0112] In one exemplary embodiment, such as Figure 3 As shown, another distributed collaborative control method for railway power supply maintenance during track openings based on a SCADA system is provided, which is then applied to... Figure 1 Taking the power supply dispatch terminal in the system as an example, the specific steps are as follows:

[0113] Step S301: Identify the candidate substation equipment terminals and candidate grounding terminals associated with the power supply dispatch terminal.

[0114] Step S302: In response to the operation instruction for the track maintenance section of the power supply dispatching terminal, the candidate substation terminal located in the track maintenance section is determined from each candidate substation terminal as the substation terminal, and the candidate grounding terminal located in the track maintenance section is determined from each candidate grounding terminal as the grounding terminal.

[0115] Step S303: Generate equipment control instructions for the substation equipment corresponding to the power supply dispatching terminal, and grounding control instructions for the grounding terminal corresponding to the power supply dispatching terminal.

[0116] Step S304: Based on the equipment control command and the grounding control command, obtain the parallel control command package corresponding to the track maintenance window section.

[0117] Step S305: Parallel equipment control commands are sent to the corresponding substation equipment terminals, enabling each substation equipment terminal to perform corresponding equipment control processing based on the equipment control commands, and the equipment control results of each substation equipment terminal are returned to the power supply dispatch terminal.

[0118] Step S306: When the equipment control results at each substation end meet the preset conditions, grounding control commands are sent in parallel to the corresponding grounding terminals, so that each grounding terminal performs the corresponding grounding control processing based on the grounding control commands, and the grounding control results of each grounding terminal are returned to the power supply dispatching terminal.

[0119] Step S307: The equipment control results and grounding control results are fused to obtain the fused control results.

[0120] Step S308: Input the fusion control result into the pre-built state verification model to obtain the state verification result corresponding to the skylight operation section; the state verification result is used to indicate whether the skylight operation section meets the preset operation conditions.

[0121] Step S309: If the status verification result indicates that the track maintenance section meets the preset operation conditions, the track maintenance section is processed according to the operation instructions.

[0122] Step S310: If the status verification result indicates that the skylight operation section does not meet the preset operation conditions, generate the fault alarm information corresponding to the skylight operation section, and perform fault alarm processing on the skylight operation section according to the fault alarm information.

[0123] In the aforementioned distributed collaborative control method for railway power supply maintenance window operations based on the SCADA system, during maintenance window operations, a parallel control command package containing two types of commands—transformer equipment control and grounding control—is generated in response to maintenance window operation instructions. These two types of control commands are then sent in parallel to both the transformer equipment end and the grounding terminal. The two types of control commands are used to simultaneously carry out equipment management and grounding handling according to the process, shortening the time spent on issuing commands and handling them on-site, which were previously executed step-by-step. Furthermore, relying on a pre-built state verification model, the control results fed back from both ends are automatically summarized, and the section operation condition verification is quickly completed. Based on the verification results, subsequent section operation handling is immediately promoted. This avoids the shortcomings of traditional technologies that use a serial, step-by-step processing method, requiring each item, each station, and each grounding switch to be completed sequentially during maintenance window operations, which easily consumes a lot of time and leads to low efficiency. Therefore, this method improves the efficiency of maintenance window operations.

[0124] In an exemplary embodiment, to more clearly illustrate the distributed collaborative control method for railway power supply maintenance windows based on a SCADA system provided in this application, the following specific embodiment will be used to describe this method in detail. In one embodiment, this application also provides a distributed collaborative control method for railway power supply maintenance windows based on a SCADA system. Specifically, it includes the following:

[0125] like Figure 4 As shown, this embodiment proposes a novel three-layer distributed collaborative control system architecture: "Dispatch Master Station (Cloud) - Substation (Edge) - Intelligent Terminal (End)". Its core innovation lies in the following: the dispatch master station no longer acts as a serial command issuer, but transforms into a collaborative manager of parallel tasks; the substation and intelligent terminal are no longer passive command executors, but autonomous execution units with local intelligence and security interlocking capabilities.

[0126] Define the ternary mapping relationship between the skylight operation section and the equipment:

[0127] Equation (1)

[0128] in:

[0129] Si: Identifier of the i-th skylight operation section.

[0130] SSi={ss{i1},ss{i2},...,ss{im}}:The set of substations supplying power to section Si.

[0131] DEi={de{i1},de{i2},...,de{ik}}:A set of intelligent voltage detection and grounding terminals deployed in section Si.

[0132] Example: Suppose there is a track closure section from K100+100 to K102+500 on a certain line ( ) by "Substation A" ( ) and "B Substation" ( Power supply was provided, and three intelligent voltage detection and grounding terminals were deployed in this section. ),but:

[0133] Equation (2)

[0134] When the dispatcher selects the track maintenance window section Si and triggers the "execute track maintenance window power outage" command, the dispatch master station generates a parallel control command packet:

[0135] Equation (3)

[0136] in:

[0137] C breaker (SS i )={Cb(ss)| ss∈SS i}: A set of circuit breaker and disconnector tripping commands for all relevant substations.

[0138] C switch (SS i ={Cs(ss)| ss∈SS i}: A set of feeder operation power disconnection commands for all relevant substations.

[0139] E ground (DE i )={Eg(de)| de∈DE i}: A set of grounding enable commands for all relevant smart terminals.

[0140] Define a global security state verification function F:

[0141] Equation (4)

[0142] Function F returns a Boolean value:

[0143] F(Si) = TRUE if and only if all relevant circuit breakers and disconnectors have been tripped, all operating power supplies have been disconnected, and all grounding terminals have been grounded; otherwise, F(Si) = FALSE.

[0144] The dispatch master station is the intelligent control center of the entire system, and includes the following core modules:

[0145] 1. Command Receiving and Parsing Module:

[0146] It provides a graphical human-machine interface (HMI) that allows dispatchers to intuitively select the track maintenance area.

[0147] Receive single-trigger commands, such as the "Execute sunroof power outage" button click event.

[0157] 4. Global State Verifier:

[0158] Collect real-time status feedback from each device.

[0175] 3. Safety interlocking logic:

[0176] Local safety verification: Ensures that the operating power supply will not be disconnected while the circuit is energized and that the grounding device will not be closed while the circuit is energized.

[0177] Operation sequence verification: Verify that the received instructions conform to the safe operation sequence.

[0178] Operating condition control: When the detected voltage or current value is greater than the specified value, it is forbidden to operate the feeder operating power switch.

[0179] Anti-misoperation logic: Prevents the execution of illegal or contradictory instructions.

[0180] New intelligent equipment deployed on-site replaces the traditional manual voltage testing and grounding process.

[0181] 1. Terminal hardware composition:

[0182] The hardware of the intelligent voltage detection and grounding terminal mainly includes: a main control unit (MCU (Microcontroller Unit) / ARM (Advanced RISC Machine)), a communication module (4G (4th Generation Mobile Communication Technology) / 5G (5th Generation Mobile Communication Technology) / fiber optic), a high-voltage voltage detection module, a controllable grounding switch (motor driven), a power management unit (battery + solar energy), a human-machine interface (LCD (Liquid Crystal Display) + buttons), a safety interlocking mechanism (mechanical / electrical), and environmental monitoring sensors.

[0214] Feedback on grounding status: Grounded / Not grounded / Grounding failed.

[0215] Feedback environmental information: temperature, humidity, and terminal location (GPS (Global Positioning System)).

[0216] The system adopts a layered communication architecture:

[0217] Between the dispatch master station and the substation: a dedicated power communication network (such as EPON (Ethernet Passive Optical Network) or industrial Ethernet) is used, requiring high reliability and low latency (<100ms).

[0218] Between the dispatch master station and the intelligent terminal: a wireless private network (LTE-R (LTE for Railway) / 5G-R (5G for Railway)) or wired fiber optic cable is used to ensure coverage of the track maintenance window section.

[0219] Time synchronization network: NTP or 1588 protocol is used to ensure that the time synchronization accuracy of the entire system is <10ms.

[0220] like Figure 5 The diagram shown is a flowchart illustrating a distributed collaborative control method for railway power supply maintenance during track openings based on a SCADA system.

[0221] The power supply process ensures safe unlocking:

[0222] 1. The dispatcher clicks the "Execute power supply during the skylight window" button.

[0223] 2. The dispatch master station sends instructions in reverse order:

[0224] (1) Send the “Reclaim Ground Enable” command to all DEi.

[0225] (2) The smart terminal automatically removes the grounding wire and provides feedback on the status.

[0226] (3) After confirming that all grounding wires have been removed, send the “Close the operating power” command to SSi.

[0227] (4) After confirming that all operating power supplies are closed, send the “Close Circuit Breaker” command to SSi.

[0228] 3. The dispatch master station runs the power supply safety verification function to confirm that the entire line is energized normally.

[0229] 4. Broadcast the message "Power supply complete".

[0230] Multi-layered security protection:

[0236] State cross-validation.

[0237] 4. Abnormal handling mechanism: command timeout resending and abandonment, automatic isolation of equipment failure, and emergency manual operation mode.

[0238] This system achieves "five protections" in electrical operation through technical means:

[0239] Preventing accidental opening and closing of circuit breakers: Centralized control through the dispatching master station avoids on-site misoperation.

[0240] To prevent the disconnector from being opened or closed under load: ensure that the operation is performed only after the power is off by controlling the power supply.

[0241] Preventing live grounding wires (grounding switches) from being connected: Intelligent terminal voltage detection interlock.

[0242] Preventing circuit breakers from being closed with the grounding wire (grounding switch): Global state verification function ensures this.

[0243] Preventing accidental entry into energized compartments: The system monitors the energized status in real time and issues alarms.

[0244] Implementation Example 1: Simple Skylight in a Single Section

[0245] Scenario: A railway section's upline line requires 2 hours of overhead contact line maintenance, affecting only a single power supply arm.

[0246] Implementation steps:

[0247] 1. Preliminary preparations:

[0248] In the dispatch master station maintenance section-equipment mapping: S = "Interval K100-K110 uplink" → SS = {substation A}, DE = {terminal 1, terminal 2}.

[0249] Predefine the operation template for this skylight type.

[0250] 2. Starting with the sunroof:

[0251] The dispatcher logs into the system and selects the maintenance window plan.

[0252] Click on the section on the SCADA system HMI map or select the corresponding program, and then click the "Execute Power Outage" button.

[0253] The system automatically executes the entire process, and displays "Working conditions are ready" after 2 minutes and 15 seconds.

[0254] The system automatically notifies the on-site work team that they can begin work.

[0255] 3. Work process:

[0256] On-site personnel saw a "grounded, ready to work" message on the smart terminal display screen.

[0257] The main dispatch station monitors the status of all equipment in real time.

[0258] If any abnormality occurs (such as terminal failure), the system will immediately issue an alarm.

[0259] 4. End of sunroof:

[0260] The on-site work supervisor confirmed that the work was completed.

[0261] The dispatcher clicks the "Execute Power Supply" button.

[0262] The system reversed the power supply process and displayed "Power supply complete" after 1 minute and 45 seconds.

[0263] The system generates and archives operation reports.

[0264] Implementation Example 2: Large Integrated Skylight

[0265] Scenario: Comprehensive maintenance of multiple tracks at a hub station, involving multiple power supply zones and multiple substations.

[0266] Implementation characteristics:

[0267] The scheduling master station manages multiple concurrently executed window processes.

[0268] The system supports batch operations and sequential control.

[0269] Provides a comprehensive status monitoring dashboard that displays the progress of all sections.

[0270] It supports priority scheduling, with critical sections being operated on first.

[0271] Implementation Example 3: Emergency Repair of Skylights:

[0272] Scenario: An overhead contact line malfunction requires an emergency power outage.

[0273] Implementation characteristics:

[0274] It supports "one-click emergency power outage" mode, and can complete the power outage and grounding in as little as 30 seconds.

[0275] Simplify some confirmation steps, prioritizing speed.

[0276] An emergency operation report is automatically generated afterward for future reference.

[0277] In the above embodiments, during track maintenance operations, a parallel control command package containing two types of commands—transformer equipment control and grounding control—is generated in response to the track maintenance operation command. These two types of control commands are then sent in parallel to both the transformer equipment and grounding terminals. The two types of control commands are used to simultaneously manage equipment and handle grounding issues according to the established process, reducing the time required for issuing commands and handling them on-site, which are typically executed step-by-step. Furthermore, a pre-built status verification model is used to automatically summarize the control results from both ends and quickly complete the section operation condition verification. Based on the verification results, subsequent section operation handling is immediately advanced. This avoids the drawbacks of traditional technologies that use a serial, step-by-step processing method, requiring each item, station, and grounding switch to be processed sequentially during track maintenance operations, which is time-consuming and leads to low efficiency. Therefore, the efficiency of track maintenance operations is improved.

[0278] It should be understood that although the steps in the flowcharts of the above embodiments are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the above embodiments may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.
