[0002] In the power system, the operation ticket is an important document to ensure the correct operation of power equipment and the safe and stable operation of the power grid. The traditional operation ticket management system has some shortcomings. For example, in the process of drafting the ticket, the standardization check of the ticket terms is not comprehensive and intelligent enough, which easily leads to the use of non-standard terms; when ordering and executing the operation ticket, there is a lack of effective anti-error check of the initial state of the equipment, topological structure, and operation sequence, which increases the risk of misoperation; at the same time, the query and data synchronization functions of the operation ticket need to be improved, which cannot meet the efficiency and accuracy requirements of power dispatching and operation personnel for the operation ticket management.

[0003] Chinese patent CN101893867A discloses an operation ticket management system, including a draft ticket module and a safety verification module. The safety verification module includes a real-time monitoring module, an operation sequence verification module and an equipment status verification module. The operation sequence verification module compares the on-site operation steps recorded by the real-time module with the operation steps in the operation list generated by the draft ticket module to determine whether the operation sequence of the on-site operator is correct. The equipment status verification module compares the on-site status of the equipment extracted by the real-time monitoring module with the initial status of the equipment recorded in the operation list to determine whether the equipment status has changed.

BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments;

[0021] Figure 1 It is a schematic diagram of the workflow of an operation ticket management system based on multidimensional data verification proposed by the present invention. DETAILED DESCRIPTION

[0022] In order to make the above-mentioned purpose, features and advantages of the present invention more obvious and easy to understand, the technical scheme in the embodiments of the present invention will be clearly and completely described below in combination with the drawings and specific implementation methods in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0023] The invention proposes an operation ticket management system based on multi-dimensional data verification, which is divided into four stages in practical use, including the ticket drafting stage, the review stage, the execution stage and the data synchronization and query stage.

[0024] The staff first drafts the ticket through the operation ticket management module. The operation ticket management module provides a variety of ticket drafting methods, including manual ticket drafting, typical ticket drafting, historical ticket drafting, equipment status drafting and short phrase drafting. During the drafting process, the ticket terminology verification module conducts a normative verification of the input operation content to ensure the standard use of the terminology of the operation ticket and prepare for subsequent review; the drafted operation ticket is reviewed by the auditor, and the equipment status verification module, topology error prevention verification module and operation sequence verification module assist in the review. After the review is passed, the operator executes according to the operation ticket. During the execution, the three modules of equipment status verification module, topology error prevention verification module and operation sequence verification module monitor the operation process in real time. When an abnormality occurs, an alarm is issued to minimize the risk as much as possible. Data synchronization will be carried out at each stage, and the draft ticket data and operation data will be updated in real time with the superior dispatching agency to ensure the timeliness and uniformity of the data.

[0025] like Figure 1 ,This system proposes an operation ticket management system based on multi-dimensional data verification,,including data acquisition module, ticket terminology verification module,,equipment status verification module, topology error prevention verification module,,operation sequence verification module, operation ticket management module and data synchronization and,query module.

[0026] The data acquisition module is responsible for collecting and monitoring the parameter data of the power grid, providing data support for the operation of the subsequent system, and establishing communication connections with the power monitoring system, equipment sensors, etc. to perform periodic data acquisition. The specific acquisition frequency is adaptively adjusted according to the data update cycle of the connected equipment; after the data is collected into the data acquisition module, the original data is preprocessed, including data repair, filtering, denoising and data format conversion. During the acquisition process, data may be missing or have obvious defects due to communication failures. For such data anomalies, data repair is required to ensure the integrity of the data. Specific data repair methods include data interpolation and anomaly substitution to deal with missing data and obvious defects; after filtering and denoising, the repaired complete data eliminates interference information and ensures the accuracy of the information; the processed information undergoes data format conversion, converting the information of high voltage and high current into information that is easy to process, such as low voltage and low current, and then converting the analog information into digital information, which is convenient for subsequent data verification.

[0027] The ticket terminology verification module is used to play a key role in the ticket drafting process. By establishing a standard library of ticket terms, the input content of the staff is verified by the ticket terminology verification module during the ticket drafting process, and the input content is compared with the standard library in real time. When there is a mismatch or non-standard terminology, a prompt box will pop up immediately to display the correct terminology or modification suggestions. The user will modify it according to the prompt and review it again after the modification. Only when it meets the terminology specifications can the ticket be successfully drafted. For example, for equipment names, unified and accurate names must be used. For example, "No. 1 main transformer" cannot be written as "No. 1 main transformer" and other non-standard expressions; for operating verbs, such as "closing", "opening", "putting in", "exiting", etc., they must be used accurately and cannot be mixed or misused. , especially some similar words in daily life, such as "disconnect" and "close". In the operation of the power system, "disconnecting the line switch" and "closing the line switch" are completely different. Terminology errors may cause the risk of misoperation. At the same time, the standard library of ticket terminology can follow the general industry standards. When the ticket terminology verification module is used to force the staff to use special terminology during the drafting of the operation ticket, the system interoperability between different regions and departments can be enhanced, the operational differences can be eliminated, and the efficiency and coordination of the power system can be ensured, which enhances the interoperability and compatibility of the operation ticket management system in the power system. When the ticket terminology verification module finds non-standard terms, it will prompt the standard terminology according to the error. The operator can quickly modify it according to the prompt, improve the efficiency of drafting the operation ticket, and then improve the efficiency of power dispatching and execution.

[0028] The equipment status verification module is used to review the operation ticket and monitor the equipment status in real time during the operation process to ensure the safety of personnel and equipment; the equipment status verification module receives information from the data acquisition module. When reviewing the operation ticket, the real-time status information, including the switch position of the equipment, the electrical parameters of the equipment operation, and the operation mode of the equipment, is verified with the initial status conditions of the equipment required in the operation ticket. If there is a mismatch, the system will display that the review is not passed to remind the operator to check the equipment status and prevent the operation ticket from being issued to ensure that the prerequisites of the operation ticket are correct. At the same time, through accurate status verification, it can effectively prevent improper operation of equipment in abnormal status. For example, when the oil temperature inside the transformer is too high or the gas relay is activated, the equipment status verification module will detect these abnormal conditions and prevent the transformer from being operated, which may aggravate the fault, such as forced closing or load voltage regulation. The system will display that the review is not passed and remind the operator that the operation is unreasonable, thereby protecting the equipment from further damage, extending the service life of the equipment, reducing the equipment maintenance cost, and ensuring the safe and stable operation of the equipment in the power system. During the execution phase, the equipment status verification phase monitors the equipment status in real time by receiving the equipment status information collected by the data acquisition module. During the operation performed by the operator, for each step of the operation, this module will immediately compare the latest status information of the equipment with the equipment status expected by the operation. For example, when the operator performs the operation of opening the disconnector of a certain line, the module will check whether the disconnector is actually in the open position, and whether the status of related equipment, such as the grounding switch on the line side and the circuit breaker on the bus side, has changed accordingly according to the operation logic. When an abnormal mismatch occurs, an alarm will be issued in time to remind the operator to stop the operation and check whether the operation is improper or a new fault occurs in the equipment to ensure correct operation and the safety of personnel and equipment.

[0029] The topology error prevention module also participates in the review of the operation ticket and monitors the execution link in real time. After the operation ticket enters the review stage, the topology error prevention module verifies the operation steps in the operation ticket based on the topological structure of the power system, simulates the topological changes caused by the switch operation and equipment operation behavior in the operation ticket, and finds that the operation behavior may form an unreasonable loop, electrical island or short circuit fault. The system will pop up a prompt warning. The auditor can ask the operator to modify the operation behavior and sequence in the operation ticket or add necessary safety measures according to the prompt, which improves the audit quality and ensures that the operation ticket can enter the execution stage only when it is correct in the topological rules, ensuring the correctness of the system operation at the source. When the operator executes the operation ticket, the topology error prevention module obtains the status information of the equipment in real time. After the operator's operation action is executed, this module compares the topological structure model after the operation action with the predicted result, records the real-time impact of each operation of the operator on the topological structure, and immediately triggers an alarm signal when the topological structure is abnormal, electrical island or short circuit occurs, which destroys the stability of the power grid, and organizes the operation to continue, prompting the operator to perform protection operations on site. For example, an operator's incorrect operation may cause the accidental connection of two busbars of different voltage levels, which may cause a serious short-circuit fault. The topology error prevention verification module will detect this erroneous topology change in an instant and stop the operation in time to prevent the accident from expanding. At the same time, this module can also provide operators with guidance and suggestions on how to deal with the current topological anomaly based on pre-set rules and emergency plans, including steps to restore the equipment status before the operation, emergency isolation of faulty equipment, or strategies to adjust the status of other related equipment to maintain the basic operation of the system, etc., to help operators respond to sudden topological problems quickly and effectively, reduce the impact on grid operation, and ensure the continuity and stability of power supply.

[0030] The order of operation is crucial for the safety of equipment and personnel, as well as the stability of power grid operation. The operation sequence verification module conducts a detailed check of the operation sequence in the operation ticket step by step according to the pre-set detailed power operation procedures and equipment operation logic rules. For example, for a complex operation ticket containing multiple substation equipment operations, this module checks whether the order is correct, such as whether all load switches connected to the bus are disconnected first, and then the bus incoming line switch is disconnected during the bus power outage operation. It will deeply analyze the logical relationship between each operation step and the previous and next steps to ensure that the operation sequence complies with industry standards and the operation procedures stipulated by the enterprise. When this module finds anomalies during the audit, it prompts the auditor in the form of a pop-up prompt box. With the help of the accurate error information provided by the operation sequence verification module, the auditor can judge the quality and feasibility of the operation ticket more scientifically and reasonably. The auditor can communicate with the operator in time and ask him to modify the operation ticket according to the correct order, thereby avoiding a series of problems caused by the wrong operation sequence during the execution stage. During the process of the operator executing the operation ticket, the operation sequence verification module obtains the execution status of each operation step in real time, including the start time, completion time and operation results of the operation, and compares these actual execution information with the preset operation sequence in the operation ticket in real time, and closely tracks whether the operation process is carried out in the predetermined order. During the execution process, if it is found that the operator's operation sequence does not match the preset sequence, the operation sequence verification module will immediately issue an alarm signal to remind the operator to stop the current operation. At the same time, the correct operation sequence and the location and nature of the current wrong operation are clearly displayed on the operation interface to guide the operator to correct the error. For example, if the operator mistakenly disconnects the high-voltage side switch first when performing the transformer power outage operation, and the operation sequence verification module detects this error, it will promptly stop the operator from continuing to the next step, such as disconnecting the low-voltage side switch, and prompt the operator to disconnect the low-voltage side switch first, and then disconnect the high-voltage side switch, so as to avoid adverse effects on the equipment and the power grid due to the wrong operation sequence. The operation sequence verification module can ensure the consistency and correctness of the entire operation process through real-time monitoring and immediate correction, so that the state changes of the equipment conform to the expected logical sequence, and provide a logical basis for the equipment state verification module and the topology error prevention verification module to predict the equipment state and topology structure.

[0031] As the core module of the system, the operation ticket management system realizes the full life cycle management of the operation ticket, ensuring the accuracy and efficiency of each link. The ticket drafting function of this system is realized through the operation ticket management module. At the same time, the editing, review, execution and archiving functions of the operation ticket also require the participation of this module. The operation ticket management module provides multiple modes for drafting tickets, including manual ticketing, typical ticketing, historical ticketing, equipment status ticketing and short phrase ticketing. The various drafting methods can be flexibly selected according to the actual situation, which improves the efficiency of drafting tickets. The details are as follows:

[0032] Manual ticketing: Operators can manually input the operation content according to the specific operation tasks and equipment conditions, including operation task description, operation steps, names of the equipment involved and other detailed information, to generate an operation ticket that meets actual needs. For example, when operating a newly built substation equipment for the first time, operators can record each operation step in detail through manual ticketing to ensure the accuracy and completeness of the operation.

[0033] Typical ticket generation: The system pre-stores typical operation ticket templates for various common operation tasks, such as substation switching operation, line power outage maintenance operation, etc. When encountering similar operation tasks, operators only need to select the corresponding typical ticket template, make appropriate modifications according to the actual situation, adjust the number and parameters of the operation equipment, etc., and then quickly generate the operation ticket, which greatly improves the efficiency of drafting tickets and ensures the standardization of the operation ticket.

[0034] Historical ticket generation: The operation ticket management module can automatically record and store the historical data of past operation tickets. When performing similar operations, operators can easily query and call historical operation tickets, refer to previous operation experience and steps, modify and improve them on this basis, and generate new operation tickets. This is very useful for repetitive operations or handling similar equipment failures, helping to reduce errors and improve the reliability of operations.

[0035] Equipment status ticket generation: Based on the real-time equipment status information obtained by the data acquisition module, the operation ticket management module can automatically generate an operation ticket that is suitable for the current equipment status. For example, when the equipment is in a fault state and needs to be repaired, the module will automatically generate an operation ticket containing a series of operation steps such as power outage, isolation of faulty equipment, and safety measures setting according to the equipment's fault type and current operating status, providing accurate operation guidance for operators and reducing the workload of manual judgment and input.

[0036] Phrase-to-ticket: Some commonly used operation phrases are pre-set in the system, and operators can quickly build operation tickets by selecting and combining these phrases. These phrases cover common operation actions, equipment status descriptions, etc., including: "Close XX switch" and "Check that the voltage of XX equipment is normal". Operators only need to select appropriate phrases and arrange and combine them according to the operation logic to generate operation tickets, which improves the speed of drafting tickets, especially for some simple and common operation tasks.

[0037] The operation ticket management module is also responsible for editing the operation ticket after it is drafted. The drafted operation ticket needs to be edited and modified. If the operator finds abnormal problems after drafting the ticket or during the review stage, the operator will modify the content of the operation ticket through the operation ticket management module; during the review stage, the reviewer reviews the operation ticket through the operation ticket management module, and the operation ticket management module automatically records the review process and results; the operation ticket after review enters the execution stage. During the execution process, the operation ticket management system records the execution time, executor, and operation results of the operation in real time. After each operation step is completed, the operation ticket management module will update the execution status of the operation ticket in real time. After the execution stage, the operation ticket automatically enters the archived state. All information on the operation ticket from drafting, review, execution, and final archiving is stored in the operation ticket management module and classified and stored to facilitate staff to conduct subsequent inquiries, statistical analysis, and accident tracing.

[0038] The data synchronization and query module uses a safe and reliable data transmission protocol to regularly upload the operation ticket data in this system to the system of the superior dispatching agency, and at the same time receive relevant data issued by the superior dispatching agency, including equipment parameter updates, operation specification adjustments and other information. When querying the operation ticket, the user can perform a combined fuzzy query based on a variety of query conditions, such as time range, operation object, operation type, operation ticket status, etc. The system quickly retrieves the matching operation ticket information in the database based on the query conditions entered by the user, and displays it to the user in a clear and intuitive way, such as displaying the key information of the operation ticket in a list format, and click to view the detailed content.

[0039] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
