Description

Technical Field

[0001] This invention relates to the field of power system dispatching technology, specifically to a full-process safety and error prevention system and method for power grid operation tickets. Background Technology

[0002] In the power grid system sector, with the continuous expansion of the power grid scale, the number of newly added power plants and substations is gradually increasing, power grid equipment is constantly growing, power grid operation modes are becoming increasingly complex, and power grid dispatching and operation tasks are becoming increasingly heavy. This significantly increases the workload of related personnel in operation and maintenance, as well as equipment repair. When performing equipment repairs or adjusting the power system operation mode, it is necessary to formulate and execute power grid operation tickets. Power grid operation tickets are an important basis for guiding on-site equipment operation and also serve as a safety guarantee for relevant personnel and electrical equipment. Therefore, the management of power grid operation tickets plays a crucial role in power work.

[0003] At present, there are many safety hazards in the management of power grid operation tickets. In the process of drafting tickets, manual filling or simple template application can easily lead to problems such as filling errors and inaccurate parameters. In the circulation process, there are situations such as non-standard procedures, lax approval, and distorted information transmission. In the execution process, there are safety accidents caused by operator errors or failure to execute according to the ticket.

[0004] To avoid significant potential safety risks in dispatching operations due to the inability to effectively prevent errors and establish a safe closed-loop system for ensuring the accuracy and standardization of power grid operation ticket management, those skilled in the art have been seeking a method to cover the entire process of power grid operation ticket safety and error prevention. This would enable error prevention and safe closed-loop control, effectively improve the reliability of dispatching operations, and further ensure the safe and stable operation of the power grid. Summary of the Invention

[0005] The purpose of this invention is to provide a full-process safety and error prevention system and method for power grid operation tickets, which can realize error prevention and safety closed-loop control, reduce the workload of dispatchers, and enhance the stability and security of power dispatch.

[0006] The power grid operation ticket full-process safety and error prevention system designed by the present invention to achieve one of the above objectives is characterized by including: The error prevention module is used to generate power grid operation tickets based on the power grid operation ticket generation method, perform error prevention verification on the instruction content of the power grid operation ticket, and obtain the verified power grid operation ticket. The error prevention module is used to send the verified power grid operation ticket creation and review task to each review node, so that each review node can review the compliance of the verified power grid operation ticket. After the review is passed, the review task is closed and the power grid operation ticket to be executed is obtained. The error prevention module is used to obtain the current status of the power grid equipment from the SCADA database, perform error prevention verification based on the instruction content of the power grid operation ticket to be executed and the current status of the power grid equipment, and obtain the verified instruction content of the power grid operation ticket to be executed.

[0007] Furthermore, the power grid operation ticket generation method of the aforementioned ticket generation and error prevention module includes: point-and-image ticket generation and template ticket generation; In the case of the point-to-point ticketing method, the target equipment nodes are obtained based on the node data of the primary wiring diagram of the power network. By parsing the electrical connection relationship and equipment attributes between the target equipment nodes, the instruction content of the corresponding power grid operation ticket is generated. In the case of template-based ticket generation, a preset power grid operation ticket template is matched according to the operation type. The corresponding operation sequence, equipment list and safety measure information are matched from the template library and filled into the corresponding preset power grid operation ticket template to generate the instruction content of the corresponding power grid operation ticket.

[0008] Furthermore, the ticket error prevention module performs error prevention verification on the instruction content of the power grid operation ticket, specifically through the following method: Based on the logic rules of equipment operation status, determine whether the equipment status in the instructions of the power grid operation ticket is consistent. If it is not consistent, give a prompt and correction suggestion. Based on the equipment bilateral terminology standard and the power dispatch terminology standard, determine whether the equipment bilateral and dispatch terminology in the instruction content of the power grid operation ticket are standardized. If not, provide prompts and correction suggestions. Based on the safety sequence rules for power outage and restoration operations, determine whether the power outage and restoration sequence in the power grid operation ticket conforms to the predetermined logic. If it does not conform, provide a prompt and correction suggestion. If none of the above judgments are abnormal, the verified power grid operation ticket is obtained.

[0009] Furthermore, the specific method for determining whether the equipment status in the instruction content of the power grid operation ticket is continuous is as follows: obtain the instruction content of the power grid operation ticket by parsing the power grid operation ticket, and extract the pre-state and post-state of each instruction in the instruction content of the power grid operation ticket. Compare the preceding and following states in each instruction. If the transition between the preceding and following states in each instruction does not conform to the state transitions allowed by the equipment, then the instruction content of the power grid operation ticket is not coherent. If the transition between the preceding and following states in each instruction conforms to the state transitions allowed by the equipment, then the instruction content of the power grid operation ticket is coherent.

[0010] Furthermore, the error prevention module sends the verified power grid operation ticket to each review node for review. The specific method is as follows: the permissions of each review node are determined according to the preset review process, and the verification power grid operation ticket is sent to each review node to create a review task. Each review node reviews the control measures corresponding to the risk warning form associated with the verification power grid operation ticket. If the control measures of the risk warning form are not implemented, the review of the verification power grid operation ticket is blocked. If the control measures of the risk warning form have been implemented, the review task is closed. If the review timeout or the review opinion is unclear, the abnormal information is sent to the main review node.

[0011] Furthermore, each review node reviews the control measures corresponding to the risk warning order associated with the verified power grid operation ticket. The specific method is as follows: obtain the execution records of each control measure in the risk warning order, and judge the execution records of each control measure in the risk warning order, including: verifying whether there is a corresponding execution record, whether the execution steps are complete, whether the execution time meets the timing requirements, whether the executor's authority meets the operation requirements, and whether the on-site monitoring data is consistent with the execution status; if any result is abnormal, the control measures of the risk warning order have not been implemented; if all results are normal, the control measures of the risk warning order have been implemented.

[0012] Furthermore, the execution error prevention module performs error prevention verification based on the instruction content of the power grid operation ticket to be executed and the current status of the power grid equipment. The specific method is as follows: The instructions of the power grid operation ticket are obtained by parsing the power grid operation ticket. Based on the instructions, the current status of the power grid equipment is obtained through the SCADA database. It is then determined whether the current status of the power grid equipment matches the instructions of the power grid operation ticket to be executed. If the current status of the power grid equipment does not match the instructions of the power grid operation ticket to be executed, the instructions of the power grid operation ticket to be executed are blocked. The status data of the shielding plate in the current power grid equipment status is obtained through the SCADA database. The instruction content of the power grid operation ticket is obtained by parsing the power grid operation ticket. The shielding plate of the current power grid equipment whose instruction content is a power supply instruction is verified. If the shielding plate of the current power grid equipment has not been removed, the instruction content of the power grid operation ticket to be executed is locked. The instructions of the power grid operation ticket are obtained by parsing the power grid operation ticket. Based on the instructions, the current status of the power grid equipment is obtained through the SCADA database. The instructions of the power grid operation ticket are checked to see if there is a direct power outage or power restoration operation on the line or transformer using a disconnector or a hot switch operation on the switch bay when the double busbar connection bus tie is in hot standby. If so, the instructions of the power grid operation ticket to be executed are blocked. The instructions of the power grid operation ticket are obtained by parsing the power grid operation ticket. Based on the instructions, the current status of the power grid equipment is obtained through the SCADA database. The instructions of the power grid operation ticket are checked to see if the equipment is energized and the grounding switch is closed or energized with the grounding switch on. If so, the instructions of the power grid operation ticket to be executed are blocked. If the current status of the power grid equipment matches the instructions in the power grid operation ticket to be executed, and the shielding plate of the current power grid equipment has been removed, and there is no operation to directly cut off or restore power to the line or transformer using a disconnector, or a hot-swap operation of the switch bay in the double busbar connection where the bus tie is in hot standby, and there is no situation where the equipment is energized with the grounding switch closed or energized with the grounding switch closed, then execute the instructions in the power grid operation ticket to be executed.

[0013] Furthermore, the method for obtaining the current status of power grid equipment through the SCADA database is as follows: by scanning the SCADA database for data points, a set of data points corresponding to the power grid equipment is obtained, and real-time power grid data is extracted from the SCADA database based on the set of data points.

[0014] The method for preventing errors in the entire process of power grid operation tickets designed by this invention to achieve the second objective mentioned above is characterized by including the following steps: A power grid operation ticket is generated based on the power grid operation ticket generation method. The instruction content of the power grid operation ticket is checked to prevent errors, and the checked power grid operation ticket is obtained. The verified power grid operation ticket is sent to each review node to create an audit task. Each review node then reviews the compliance of the verified power grid operation ticket. Once the audit is passed, the audit task is closed, and the power grid operation ticket to be executed is obtained. The current status of the power grid equipment is obtained from the SCADA database. The error prevention verification is performed based on the instruction content of the power grid operation ticket to be executed and the current status of the power grid equipment to obtain the verified instruction content of the power grid operation ticket to be executed.

[0015] An electronic device designed by the present invention to achieve the third objective mentioned above includes: At least one processor; and A memory communicatively connected to the at least one processor; wherein, The memory stores instructions that can be executed by the at least one processor to enable the at least one processor to perform the methods described in this disclosure.

[0016] The present invention has the following beneficial effects: (1) The whole-process safety anti-error system and method of the power grid operation ticket, by setting anti-error mechanisms in the whole process of "ticket formation, circulation and execution", realizes the automated verification and dynamic anti-error control of the whole process of power grid operation ticket from generation and review to execution. In the ticket formation stage, the system can intelligently verify the logic, terminology and sequence of operation instructions to ensure that the content of the ticket is accurate and standardized; in the circulation stage, the system can realize the step-by-step confirmation and error correction of power grid operation ticket information through a multi-node review mechanism; in the execution stage, the system can compare and lock the operation instructions in combination with the real-time equipment status to prevent the occurrence of misoperation; and realize the whole-process safety traceability and risk warning through closed-loop recording and abnormal alarm mechanism.

[0017] (2) The whole-process safety anti-error system and method of the power grid operation ticket can detect potential logical errors and non-standard terminology problems in advance during the ticket preparation stage by intelligently verifying the continuity of equipment status, standardization of terminology and power outage logic, and provide correction suggestions to achieve error prevention before ticket completion. The circulation anti-error module can check the integrity of information in the power grid operation ticket review process. When incomplete or abnormal parameters are found, it will be automatically returned and the reason will be prompted, forming an anti-error closed loop at the review level, improving the quality of the ticket and the controllability of management. The execution anti-error module can automatically lock the relevant instructions when they do not match by comparing and verifying the content of the power grid operation ticket instructions with the real-time equipment status, preventing erroneous execution and forming the last safety barrier in the execution stage.

[0018] Figure 1 This diagram illustrates a module schematic of a specific embodiment of a full-process safety and error prevention system for power grid operation tickets according to the present invention.

[0019] Figure 2 This is a flowchart illustrating a specific embodiment of a full-process safety and error prevention method for power grid operation tickets according to the present invention. Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0021] like Figures 1 to 2As shown in the figure, this invention discloses a full-process safety and error prevention system and method for power grid operation tickets. It utilizes the characteristics of text data generated during the historical dispatch retrieval process of the power grid, and obtains scene semantic keywords through text extraction and data parsing, thereby improving the level of intelligent information retrieval, reducing the workload of dispatchers, and enhancing the stability and security of the power dispatch automation system.

[0022] Example 1 This embodiment discloses a full-process safety and error prevention system for power grid operation tickets. The system includes: The error prevention module is used to generate power grid operation tickets based on the power grid operation ticket generation method, perform error prevention verification on the instruction content of the power grid operation ticket, and obtain the verified power grid operation ticket. The error prevention module is used to send the verified power grid operation ticket creation and review task to each review node, so that each review node can review the compliance of the verified power grid operation ticket. After the review is passed, the review task is closed and the power grid operation ticket to be executed is obtained. The error prevention module is used to obtain the current status of the power grid equipment from the SCADA database, perform error prevention verification based on the instruction content of the power grid operation ticket to be executed and the current status of the power grid equipment, and obtain the verified instruction content of the power grid operation ticket to be executed.

[0023] Specifically, the power grid operation ticket generation method of the ticket generation and error prevention module includes: point-map ticket generation and template ticket generation; In the point-map ticketing method, based on the node data of the primary wiring diagram of the power network, the target equipment node is obtained. By parsing the electrical connection relationship and equipment attributes between the target equipment nodes, the instruction content of the corresponding power grid operation ticket is generated. For example, when the dispatcher selects a certain equipment, based on the equipment information (id, connection point number, on / off status, etc.), a topology lookup analysis is performed through the connection point number to find equipment directly or indirectly connected to this equipment (equivalent to the same connection point number). The status of the equipment is then determined (e.g., the status of a switch is determined by the switch itself and the two disconnectors connected to the switch being in the closed position, and the grounding switch being in the open position for it to be considered operational). The status is then displayed in the generated menu. After the dispatcher confirms the target status, the equipment, current status, target status, etc., are concatenated into strings to form the instruction content.

[0024] In the case of template-based ticket generation, a preset power grid operation ticket template is matched according to the operation type. The corresponding operation sequence, equipment list, and safety measure information are matched from the template library and filled into the corresponding preset power grid operation ticket template to generate the instruction content of the corresponding power grid operation ticket. For example, if a main transformer needs to be switched from operation to maintenance, the dispatcher only needs to select the corresponding main transformer. After the initial and final status, the ticket generation module will automatically analyze and obtain the three switches that need to be operated and other equipment in the bay that need to be operated. Then, according to the matched template, the equipment that needs to be operated is filled in in sequence.

[0025] The instructions on the power grid operation ticket are as follows: <kv>kV <210> Depend on <cur>Turn to <tar>--- Template for a single order. The template for the entire ticket is composed of multiple single orders, including the operation sequence. 210 refers to the detailed equipment type, here indicating the main transformer switch. <kv>--Voltage level <cur> <tar>Initial and final states.

[0026] Specifically, the ticket error prevention module verifies the instruction content of the power grid operation ticket to prevent errors. The specific method is as follows: Based on the logic rules of equipment operation status, determine whether the equipment status in the instructions of the power grid operation ticket is consistent. If it is not consistent, give a prompt and correction suggestion. For example, when obtaining the instruction content of a power grid operation ticket, if the instruction content is: A switches from operation to hot standby; A switches from cold standby to maintenance; the prompts and correction suggestions are: A switches from operation to hot standby; A switches from hot standby to cold standby; A switches from cold standby to maintenance.

[0027] Based on the equipment bilateral terminology standard and the power dispatch terminology standard, determine whether the equipment bilateral and dispatch terminology in the instruction content of the power grid operation ticket are standardized. If not, provide prompts and correction suggestions. It should be noted that the dispatching terminology is determined according to the dispatching operation specifications, which are guidance documents provided by the State Grid Corporation of China.

[0028] Based on the safety sequence rules for power outage and restoration operations, determine whether the power outage and restoration sequence in the power grid operation ticket conforms to the predetermined logic. If it does not conform, provide a prompt and correction suggestion. To illustrate, for example: when operating the main transformer, power outages should be performed in the following order: low-medium-high, and power restoration should be performed in the following order: high-medium-low.

[0029] If none of the above judgments are abnormal, the verified power grid operation ticket is obtained.

[0030] Specifically, the method for determining whether the equipment status in the instruction content of the power grid operation ticket is continuous is as follows: obtain the instruction content of the power grid operation ticket by parsing the power grid operation ticket, and extract the pre-state and post-state of each instruction in the instruction content of the power grid operation ticket. Compare the preceding and following states in each instruction. If the transition between the preceding and following states in each instruction does not conform to the state transitions allowed by the equipment, then the instruction content of the power grid operation ticket is not coherent. If the transition between the preceding and following states in each instruction conforms to the state transitions allowed by the equipment, then the instruction content of the power grid operation ticket is coherent.

[0031] Specifically, the error prevention module sends the verified power grid operation ticket to each review node for review. The specific method is as follows: the permissions of each review node are determined according to the preset review process, and the verification power grid operation ticket is sent to each review node to create a review task. Each review node reviews the control measures corresponding to the risk warning form associated with the verification power grid operation ticket. If the control measures of the risk warning form are not implemented, the review of the verification power grid operation ticket is blocked. If the control measures of the risk warning form have been implemented, the review task is closed. If the review timeout or the review opinion is unclear, the abnormal information is sent to the main review node.

[0032] It should be noted that the preset review process is as follows: first review - second review - leadership review (if applicable) - pre-issuance; each review node has a corresponding person in charge, and each person in charge has different permissions. For example, if A only has the permission to draft the ticket, then A cannot see the content after the drafting node, and can only operate on the ticket when drafting the ticket; the verification of the circulation node is carried out when submitting for review. Each power grid operation ticket is associated with a work ticket or a risk warning form. During verification, the method adjustment content in the work ticket and the security measures in the risk warning form are verified to check whether the ticket has the conditions for execution.

[0033] Furthermore, each review node reviews the control measures corresponding to the risk warning order associated with the verified power grid operation ticket. The specific method is as follows: obtain the execution records of each control measure in the risk warning order, and judge the execution records of each control measure in the risk warning order, including: verifying whether there is a corresponding execution record, whether the execution steps are complete, whether the execution time meets the timing requirements, whether the executor's authority meets the operation requirements, and whether the on-site monitoring data is consistent with the execution status; if any result is abnormal, the control measures of the risk warning order have not been implemented; if all results are normal, the control measures of the risk warning order have been implemented.

[0034] For example, in a 110kV single busbar sectionalized substation, one side of the line needs to be transferred for maintenance. The safety measures in the risk warning form will include: transfer the load and ensure power supply. The specific operation method is to close the busbar switch and open the other power supply line, and open the busbar switch. It is necessary to verify whether the above operation has been completed. Specifically, the execution error prevention module performs error prevention verification based on the instruction content of the power grid operation ticket to be executed and the current status of the power grid equipment. The specific method is as follows: The instructions of the power grid operation ticket are obtained by parsing the power grid operation ticket. Based on the instructions, the current status of the power grid equipment is obtained through the SCADA database. It is then determined whether the current status of the power grid equipment matches the instructions of the power grid operation ticket to be executed. If the current status of the power grid equipment does not match the instructions of the power grid operation ticket to be executed, the instructions of the power grid operation ticket to be executed are blocked. For example, when obtaining the instruction content of a power grid operation ticket, if the instruction content is: A is to switch from operation to hot standby; before execution, it is necessary to determine whether the real-time status of A is operation, and at the end of execution, it is necessary to determine whether the real-time status of A is hot standby. The status data of the shielding plate in the current power grid equipment status is obtained through the SCADA database. The instruction content of the power grid operation ticket is obtained by parsing the power grid operation ticket. The shielding plate of the current power grid equipment whose instruction content is a power supply instruction is verified. If the shielding plate of the current power grid equipment has not been removed, the instruction content of the power grid operation ticket to be executed is locked. For example, when obtaining the instruction content of a power grid operation ticket, if the instruction content is: A is switched from maintenance to cold standby; before execution, it is necessary to verify whether there is a shielding plate on equipment A (reflected in the database). If there is a shielding plate, the maintenance work has not been completed and power cannot be supplied. The instructions of the power grid operation ticket are obtained by parsing the power grid operation ticket. Based on the instructions, the current status of the power grid equipment is obtained through the SCADA database. The instructions of the power grid operation ticket are checked to see if there is a direct power outage or power restoration operation on the line or transformer using a disconnector or a hot switch operation on the switch bay when the double busbar connection bus tie is in hot standby. If so, the instructions of the power grid operation ticket to be executed are blocked. It should be noted that when using a disconnector to directly cut off or restore power, for main transformers with internal bridge wiring and lines with special wiring methods (where there is only one disconnector on the line), the switches on both sides of the disconnector must be disconnected before the operation can be performed; for busbar switching, the bus tie switch must be in the running state. The instructions of the power grid operation ticket are obtained by parsing the power grid operation ticket. Based on the instructions, the current status of the power grid equipment is obtained through the SCADA database. The instructions of the power grid operation ticket are checked to see if the equipment is energized and the grounding switch is closed or energized with the grounding switch on. If so, the instructions of the power grid operation ticket to be executed are blocked. It should be noted that when using a disconnector to directly cut off or restore power, for main transformers with internal bridge wiring and lines with special wiring methods (where there is only one disconnector on the line), the switches on both sides of the disconnector must be disconnected before the operation can be performed; for busbar switching, the bus tie switch must be in the running state. If the current status of the power grid equipment matches the instructions in the power grid operation ticket to be executed, and the shielding plate of the current power grid equipment has been removed, and there is no operation to directly cut off or restore power to the line or transformer using a disconnector, or a hot-swap operation of the switch bay in the double busbar connection where the bus tie is in hot standby, and there is no situation where the equipment is energized with the grounding switch closed or energized with the grounding switch closed, then execute the instructions in the power grid operation ticket to be executed.

[0035] For example, when obtaining the instruction content of a power grid operation ticket, if the instruction content is: A is switched from maintenance to cold standby; if the grounding switch of A is still in the closed position at this time, the operation is prohibited. Furthermore, the method for obtaining the current status of power grid equipment through the SCADA database is as follows: by scanning the SCADA database for data points, a set of data points corresponding to the power grid equipment is obtained, and real-time power grid data is extracted from the SCADA database based on the set of data points.

[0036] For example, based on the unique device code of the power grid equipment, retrieve the data point number corresponding to the remote signaling, remote measurement and remote control quantities related to the equipment from the SCADA database point table; construct the data point set of the target equipment based on the retrieved data point number, and initiate a batch read request to the SCADA database according to the data point set to extract real-time data such as the current switch status, voltage, current, protection pressure plate status and related interlocking quantities of the target equipment.

[0037] Example 2 This embodiment discloses a full-process safety and error prevention method for power grid operation tickets, which includes the following steps: Step 1: Generate a power grid operation ticket based on the power grid operation ticket generation method, and perform error prevention verification on the instruction content of the power grid operation ticket to obtain the verified power grid operation ticket; Step 2: Send the verified power grid operation ticket to each review node to create an audit task. Each review node will then review the compliance of the verified power grid operation ticket. Once the audit is passed, the audit task will be closed, and the power grid operation ticket to be executed will be obtained. Step 3: Obtain the current status of the power grid equipment from the SCADA database, and perform error prevention verification based on the instruction content of the power grid operation ticket to be executed and the current status of the power grid equipment to obtain the verified instruction content of the power grid operation ticket to be executed.

7. The full flow safety misoperation prevention system for power grid operation ticket according to claim 1, characterized in that, The error prevention module performs error prevention verification based on the instruction content of the power grid operation ticket to be executed and the current status of the power grid equipment. The specific method is as follows: The instructions of the power grid operation ticket are obtained by parsing the power grid operation ticket. Based on the instructions, the current status of the power grid equipment is obtained through the SCADA database. It is then determined whether the current status of the power grid equipment matches the instructions of the power grid operation ticket to be executed. If the current status of the power grid equipment does not match the instructions of the power grid operation ticket to be executed, the instructions of the power grid operation ticket to be executed are blocked. The status data of the shielding plate in the current power grid equipment status is obtained through the SCADA database. The instruction content of the power grid operation ticket is obtained by parsing the power grid operation ticket. The shielding plate of the current power grid equipment whose instruction content is a power supply instruction is verified. If the shielding plate of the current power grid equipment has not been removed, the instruction content of the power grid operation ticket to be executed is locked. The instructions of the power grid operation ticket are obtained by parsing the power grid operation ticket. Based on the instructions, the current status of the power grid equipment is obtained through the SCADA database. The instructions of the power grid operation ticket are checked to see if there is a direct power outage or power restoration operation on the line or transformer using a disconnector or a hot switch operation on the switch bay when the double busbar connection bus tie is in hot standby. If so, the instructions of the power grid operation ticket to be executed are blocked. The instructions of the power grid operation ticket are obtained by parsing the power grid operation ticket. Based on the instructions, the current status of the power grid equipment is obtained through the SCADA database. The instructions of the power grid operation ticket are checked to see if the equipment is energized and the grounding switch is closed or energized with the grounding switch on. If so, the instructions of the power grid operation ticket to be executed are blocked. If the state of the current power grid equipment is consistent with the instruction content of the to-be-executed power grid operation order, the shielding plate of the current power grid equipment has been removed, there is no direct switching interval hot switching operation on the line and transformer with the knife switch, or there is no hot standby switching interval hot switching operation at the double bus connection bus tie, and there is no device live grounding or live grounding switching-on when the ground knife is closed, the instruction content of the to-be-executed power grid operation order is executed.
