Description

Technical Field

[0001] This invention relates to the field of daily management and operation technology of distribution network dispatching, and in particular to a comprehensive verification system and method for distribution network dispatching instruction tickets based on equipment operating condition array. Background Technology

[0002] As the transformation and construction of smart distribution networks progresses into more complex areas, improving power supply reliability has become an increasingly important indicator. Distribution network feeder automation is a key technology and method for improving power supply reliability. In recent years, with several waves of distribution network automation construction, distribution network automation technology has made significant progress, effectively ensuring the reliability of power supply from the distribution network.

[0003] However, as the scale of power distribution network construction increases, the equipment monitored by dispatchers becomes larger, and there are many shortcomings in the accuracy of data collected by field terminals. As a result, when dispatchers perform remote operation and change the operation mode, they often cause accidents to escalate due to misoperation, affecting normal power supply. In some cases, it can even lead to serious production accidents and casualties.

[0004] Therefore, it is necessary to establish a method for real-time safety and error prevention verification of distribution network equipment operation. This method can effectively avoid dispatcher errors, ensure the safe operation of the power grid, and guarantee the reliability of the power supply system. This has important practical significance. Summary of the Invention

[0005] This invention addresses the shortcomings and deficiencies of existing technologies, specifically the issue of preventing operational errors in distribution network dispatching. It proposes a comprehensive verification system and method for distribution network dispatching command tickets based on an equipment condition matrix. This system resolves inconsistencies between the draft dispatching command ticket and the actual equipment status during the programmed dispatching process in distribution networks, as well as addressing five-fold safety concerns. By establishing an initial state condition matrix to record key factors such as the status information of relevant equipment on the command ticket, a real-time analysis of the generated equipment condition difference matrix is ​​performed. Inconsistencies between the intended operational status of the equipment on the command ticket and the real-time status are identified, prompting warnings to the dispatcher. Furthermore, the system performs five-fold safety verification on the command ticket, improving the security of dispatching command execution.

[0006] The specific technical solution adopted is as follows:

[0007] A comprehensive verification system for power distribution network dispatching command tickets based on equipment condition arrays, characterized in that it includes: a command ticket objectification module and a command ticket equipment condition array verification module;

[0008] The instruction ticket objectification module is used to first distinguish the type of operating device for each instruction ticket step, and then process its text to find the operating device corresponding to the instruction ticket step through database fuzzy matching.

[0009] The instruction ticket equipment status verification module is used to perform five-proof verification and equipment status verification on the instruction ticket by means of the topological relationship of the equipment associated with the instruction ticket when the instruction ticket is drafted or executed.

[0010] Furthermore, the operation of the instruction ticket objectification module is as follows:

[0011] 1. For step A of the instruction ticket, first distinguish the type of equipment to be operated. If step A of the instruction ticket contains "line to cold standby," "line to maintenance," "switch," "to operation," or "to cold standby," and does not contain the word "busbar," then the operation object of this safety measure is considered to be the switch. If step A of the instruction ticket contains "disconnector" or "drop-out fuse," then the operation object of this safety measure is considered to be the disconnector. If step A of the instruction ticket contains "busbar transfer," then the operation object of this instruction ticket step is considered to be the busbar. If step A of the instruction ticket contains "transformer transfer," then the operation object of this safety measure is considered to be the distribution transformer.

[0012] 2. Based on the operation equipment type of step A in the instruction ticket determined in step 1, continue to analyze step A of the instruction ticket, and remove the operation terms of the instruction ticket steps to obtain text B;

[0013] 3. Analyze the text B processed in step 2. First, analyze whether the instruction ticket steps contain the equipment plant name. The analysis method is to search for the following keywords: switch station, ring main unit, power distribution room, power distribution station, switch room, switch station, substation. By extracting the text before these keywords, we can obtain the plant name C. Then, remove the text C from step A of the instruction ticket to obtain the text D.

[0014] 4. Based on the factory name C to which the equipment belongs, use fuzzy text matching to find the factory name to which the equipment belongs. Then, based on the text D, use fuzzy text matching to find one or more equipment names of the same type that meet the conditions. Finally, determine the factory name to which the equipment belongs by comparing the found equipment names.

[0015] 5. If only one device is resolved in step 4, the device resolution is completed directly. If multiple devices are resolved, the following operation is performed to continue resolving: Determine whether all resolved device names are included in step A of the instruction ticket. If the device name is included in step A of the instruction ticket, record the length of the device name. Otherwise, remove it. Finally, select the device whose device name is included in step A of the instruction ticket and has the longest device name as the final resolved device.

[0016] Furthermore, the instruction ticket equipment condition array verification module performs the following operations when executing the drafting of the instruction ticket:

[0017] (1) Locate the feeder where the device to be operated is located based on the topology;

[0018] (2) For each feeder, based on the equipment node connection relationship and real-time remote signaling, establish a feeder tree model with the substation outgoing switch as the root, each distribution transformer, tie switch and suspended feeder section as the leaves, and each feeder main path and branch feeder as the trunk.

[0019] (3) Perform error prevention verification on the instruction ticket based on the feeder tree topology and real-time data, and verify the instruction ticket based on the operation content;

[0020] The instruction ticket equipment condition array verification module performs the following operations during execution:

[0021] (1) Locate the feeder line where the device associated with the instruction ticket step to be executed is located;

[0022] (2) Perform topology analysis on the feeder based on real-time data;

[0023] (3) Verify the steps of the instruction ticket.

[0024] Furthermore, the specific verification process is as follows:

[0025] a. Closing and opening disconnect switches under load: If the operating device is a disconnect switch and the downstream of the operating disconnect switch can be connected to the distribution transformer in the feeder tree in real time, then the operation is considered to violate the verification of closing and opening disconnect switches under load.

[0026] b. Live grounding switch: If the operating device is a grounding switch, and the grounding switch is powered on in the feeder tree during the simulated grounding switch closing, then the operation is considered to have violated the live grounding switch closing verification.

[0027] c. Powering on with grounding switch: If, after the simulation operation equipment is closed, the feeder tree can be topologically analyzed to find the grounding switch and the grounding switch is in the closed position, then the operation is considered to have violated the powering on with grounding switch verification.

[0028] d. Equipment status verification: For the operation purpose of the instruction ticket step, compare the real-time status of the equipment associated with the instruction ticket step with that equipment. If the status of the operation purpose is consistent with the real-time status, the equipment status verification for that operation is considered to have failed.

[0029] Once a step in a command ticket is verified, the status of the device associated with that command ticket is set to the operation status of that step. Then, the next step in the command ticket is verified, and so on, until all steps are verified.

[0030] Furthermore, a comprehensive verification system for distribution network dispatching instruction tickets based on equipment operating condition arrays, characterized by comprising the following steps:

[0031] Step S1: Instruction Ticket Objectification: By parsing the text in the instruction ticket, the steps in the instruction ticket are associated with the corresponding operating devices;

[0032] Step S2: Equipment status verification during ticket drafting: During ticket drafting, the instruction ticket is verified for five protections and equipment status based on the topology relationship of the equipment associated with the instruction ticket;

[0033] Step S3: Execution of Command Ticket Equipment Status Verification: During execution, the command ticket is verified for five protections and equipment status through the topology relationship of the command ticket associated with the equipment.

[0034] Furthermore, step S1 specifically includes the following steps:

[0035] Step S11: For step A of the instruction ticket, first distinguish the type of operating equipment. If step A of the instruction ticket contains "line to cold standby," "line to maintenance," "switch," "to operation," or "to cold standby," and does not contain the word "busbar," then the operating object of this safety measure is considered to be the switch. If step A of the instruction ticket contains "disconnector" or "drop-out fuse," then the operating object of this safety measure is considered to be the disconnector. If step A of the instruction ticket contains "busbar transfer," then the operating object of this instruction ticket step is considered to be the busbar. If step A of the instruction ticket contains "transformer transfer," then the operating object of this safety measure is considered to be the distribution transformer.

[0036] Step S12: Based on the operation device type of step A in the instruction ticket determined in step S11, continue to analyze step A in the instruction ticket and remove the operation terms of the instruction ticket steps to obtain text B;

[0037] Step S13: Analyze the text B processed in step S12. First, analyze whether the instruction ticket steps contain the equipment plant name. The analysis method is to search for the following keywords: switch station, ring main unit, power distribution room, power distribution station, switch room, switch station, substation. By extracting the text before these keywords, we can obtain the plant name C. Then, remove the text C from step A of the instruction ticket to obtain the text D.

[0038] Step S14: Based on the factory name C to which the equipment belongs, find the factory to which the equipment belongs by fuzzy matching of all factory names. Then, based on the text D, find one or more equipment that meet the conditions by fuzzy matching of all equipment names of this type. Finally, determine the one or more equipment that were parsed out by comparing the factory to which the equipment belongs.

[0039] Step S15: If only one device is parsed in step S14, the device parsing is completed directly. If multiple devices are parsed, the following operation is performed to continue parsing: Determine whether all parsed device names are included in step A of the instruction ticket. If the device name is included in step A of the instruction ticket, record the length of the device name. Otherwise, remove it. Finally, select the device whose device name is included in step A of the instruction ticket and has the longest device name as the final parsed device.

[0040] Furthermore, step S2 specifically includes the following steps:

[0041] Step S21: Locate the feeder where the device to be operated is located based on the topology;

[0042] Step S22: For each feeder, based on the equipment node connection relationship and real-time remote signaling status, establish a feeder tree model with the substation outgoing switch as the root, each distribution transformer, tie switch and suspended feeder section as the leaves, and each feeder main path and branch feeder as the trunk.

[0043] Step S23: Perform error prevention verification on the instruction ticket based on the feeder tree topology and real-time data, and verify the instruction ticket according to the operation content. Verify the instruction ticket step by step according to the operation content, including opening and closing the disconnect switch under load, opening and closing the grounding switch under power, energizing the grounding switch, and verifying the equipment status. After verification, set the equipment status of the step to the target operation status, then re-topologize the feeder tree and verify the next step of the instruction ticket.

[0044] Furthermore, step S3 specifically includes the following steps:

[0045] Step S31: Locate the feeder where the device associated with the instruction ticket step to be executed is located;

[0046] Step S32: Perform topology analysis on the feeder based on real-time data;

[0049] a. Closing and opening disconnect switches under load: If the operating device is a disconnect switch and the downstream of the operating disconnect switch can be connected to the distribution transformer in the feeder tree in real time, then the operation is considered to violate the verification of closing and opening disconnect switches under load.

[0050] b. Live grounding switch: If the operating device is a grounding switch, and the grounding switch is powered on in the feeder tree during the simulated grounding switch closing, then the operation is considered to have violated the live grounding switch closing verification.

[0051] c. Powering on with grounding switch: If, after the simulation operation equipment is closed, the feeder tree can be topologically analyzed to find the grounding switch and the grounding switch is in the closed position, then the operation is considered to have violated the powering on with grounding switch verification.

[0052] d. Equipment status verification: For the operation purpose of the instruction ticket step, compare the real-time status of the equipment associated with the instruction ticket step with that equipment. If the status of the operation purpose is consistent with the real-time status, the equipment status verification for that operation is considered to have failed.

[0053] Once a step in a command ticket is verified, the status of the device associated with that command ticket is set to the operation status of that step. Then, the next step in the command ticket is verified, and so on, until all steps are verified.

[0059] The comprehensive verification scheme for distribution network dispatching instruction tickets based on equipment operating condition arrays provided in this embodiment includes: objectifying the instruction ticket process, performing error prevention verification on the instruction ticket during drafting, and performing error prevention verification on the instruction ticket during execution. Specifically:

[0063] The following is a detailed description of this embodiment:

[0064] A comprehensive verification method for distribution network dispatching instruction tickets based on equipment condition array:

[0065] Step 1: Objectifying the Instruction Ticket

[0066] 1. For step A of the instruction ticket, first distinguish the type of operating equipment. If step A of the instruction ticket contains "line to cold standby", "line to maintenance", "switch", "to operation", "to cold standby", and does not contain the word "busbar", then the operating object of the safety measure is considered to be the switch. If step A of the instruction ticket contains "knife switch" or "drop-out fuse", then the operating object of the safety measure is considered to be the knife switch. If step A of the instruction ticket contains "busbar transfer", then the operating object of the instruction ticket step is considered to be the busbar. If step A of the instruction ticket contains "transformer transfer", then the operating object of the safety measure is considered to be the distribution transformer.

[0067] 2. After determining the type of operating equipment for step A of the instruction ticket based on step 1, continue to analyze step A of the instruction ticket. First, remove the operation terms in the instruction ticket step that include the following text: line to maintenance, line to cold standby, transformer to maintenance, busbar to maintenance, switch to maintenance, etc. to obtain text B.

[0068] 3. Analyze the text B processed in step 2. First, analyze whether the instruction ticket contains the equipment plant name. The analysis method is to search for the following keywords: switch station, ring main unit, power distribution room, power distribution station, switch room, switch station, substation. Extract the text before these keywords to obtain the plant name C. Then remove text C from step A of the instruction ticket to obtain text D.

[0069] 4. Based on the plant name C to which the equipment belongs, use fuzzy text matching to find the plant name to which the equipment belongs. Then, based on the text D, use fuzzy text matching to find the equipment (one or more) that meets the conditions. Finally, determine the parsed equipment (one or more) by comparing the plant names to which the equipment belongs.

[0070] 5. If only one device is parsed in step 4, the device parsing is complete. If multiple devices are parsed, the following operations are performed to continue parsing: determine whether all parsed device names are included in step A of the instruction ticket. If the device name is included in step A of the instruction ticket, record the length of the device name; otherwise, remove it. Finally, select the device whose device name is included in step A of the instruction ticket and has the longest device name as the final parsed device.

[0071] Step 2: Error prevention verification during ticket drafting

[0072] 1. First, locate the feeder to which the instruction ticket step associated with the device to be verified belongs based on the topology;

[0073] 2. For each feeder, based on the equipment node connection relationship and real-time remote signaling status, establish a feeder tree model with the substation outgoing switch as the root, each distribution transformer, tie switch and suspended feeder section as the leaves, and each feeder main path and branch feeder as the trunk.

[0074] 3. Based on the established feeder tree, perform the following verification steps on an instruction ticket.

[0075] a. Closing and opening disconnect switches under load: If the operating device is a disconnect switch and the downstream of the operating disconnect switch can be connected to the distribution transformer in the feeder tree in real time, then the operation is considered to violate the verification of closing and opening disconnect switches under load.

[0076] b. Live grounding switch: If the operating device is a grounding switch, and the grounding switch is powered on in the feeder tree during the simulated grounding switch closing, then the operation is considered to have violated the live grounding switch closing verification.

[0077] c. Powering on with grounding switch: If, after the simulation operation equipment is closed, the feeder tree can be topologically analyzed to find the grounding switch and the grounding switch is in the closed position, then the operation is considered to have violated the powering on with grounding switch verification.

[0078] d. Equipment status verification: For the operation purpose of the instruction ticket step, compare the real-time status of the equipment associated with the instruction ticket step with that equipment. If the status of the operation purpose is consistent with the real-time status, the equipment status verification for that operation is considered to have failed.

[0079] After the verification of the instruction ticket step is completed, the status of the device associated with the instruction ticket is set to the operation status of the instruction ticket step, and then the next instruction ticket step is verified, until all steps are verified.

[0080] Step 3: Error prevention verification of instruction ticket during execution

[0081] When executing the instruction ticket, the steps to be ordered include closing and opening disconnect switches under load, closing grounding switches while energized, energizing grounding switches, and verifying equipment status. If the verification fails, a prompt will be given.
