Technical Field

[0001] This invention belongs to the field of intelligent operation and maintenance technology of substations, and particularly relates to a method and system for automatically generating substation interlocking control tasks. Background Technology

[0002] As a critical node in the power system, the safety of equipment operation in substations is paramount. Daily operation and maintenance of substations involves numerous equipment interlocking and unlocking operations. Traditional interlocking management relies heavily on manual experience, which presents the following problems:

[0003] Operational plans are out of sync with on-site conditions: Operational plans are usually formulated in advance, but real-time changes in equipment status cannot be fed back into the task execution in a timely manner, which may result in tasks being issued even when the operating conditions are not met.

[0004] The existing system has a crude approach to personnel access control: it has a simple approach to managing the access rights of operators and cannot perform fine-grained access control matching based on the specific type of equipment operation, which poses a security risk.

[0005] Inflexible task adjustment: When equipment status changes or abnormalities occur during operation, it is difficult to adjust the subsequent task sequence in a timely manner, affecting operational efficiency.

[0006] Lack of closed-loop management: After a task is issued, there is a lack of effective status tracking and feedback mechanisms, making it impossible to form a complete operational closed loop.

[0007] Therefore, there is an urgent need for a solution that can intelligently generate lock control tasks and dynamically adjust them according to real-time status. Summary of the Invention

[0008] This invention provides a method and system for automatically generating substation interlocking control tasks, which solves the technical problems of easy error and low efficiency caused by human judgment in existing interlocking control management.

[0012] Based on the equipment operating status data, determine whether each piece of equipment to be operated meets the operating conditions, and generate equipment status assessment results;

[0013] By combining the equipment status assessment results with the operation timing relationship, a lock control operation logic diagram is constructed. The lock control operation logic diagram includes equipment nodes, operation sequence constraints, and state dependencies.

[0014] Based on the lock control operation logic diagram and the current operator's permission information, a lock control task sequence matching the operator's permissions is generated;

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1The diagram shows a flowchart of an automatic generation method for substation interlocking tasks according to this application.

[0034] like Figure 1 As shown, the automatic generation method for substation interlocking control tasks includes the following steps:

[0035] Step S101: Obtain substation equipment operation plan information, equipment operation status data, and current operator permission information.

[0036] Specifically, equipment operation plan information can be obtained from the production management system, including equipment operation instructions, operation time windows, and other information; equipment operation status data is collected in real time through the substation monitoring system, including electrical parameters, mechanical status signals, and other information; operator permission information is obtained from the permission management system, including personnel identity, operation level, authorized equipment scope, etc.

[0037] Step S102: Based on the equipment operation plan information, identify the set of equipment to be operated and their operation sequence relationship.

[0038] In this step, the device identifier and operation type are extracted by parsing the operation instruction text in the operation plan. Combined with the device topology database, the device to be operated and its associated devices are identified. Based on the operation time window and device operation dependency rules, a device operation timing network is constructed, generating an operation timing relationship table.

[0039] Step S103: Based on the equipment operating status data, determine whether each device to be operated meets the operating conditions, and generate equipment status evaluation results.

[0040] In this step, real-time collected device status data is input into a preset device status assessment model. This model is trained using a machine learning algorithm and can output a device status score. By comparing the status score with a preset threshold, it is determined whether the device is in an operable state.

[0041] Step S104: Combining the device status evaluation results with the operation timing relationship, construct a lock control operation logic diagram. The lock control operation logic diagram includes device nodes, operation sequence constraints, and state dependencies.

[0042] In this step, the lock control operation logic graph uses device nodes as vertices, with operation order constraints represented by directed edges, and also includes state dependencies. Device nodes that do not meet the operation conditions are removed from the graph to ensure that the generated task sequences are all executable.

[0043] Step S105: Generate a lock control task sequence that matches the operator's permissions based on the lock control operation logic diagram and the current operator's permission information.

[0044] In this step, the required operation permission level of each device node in the lock control operation logic diagram is analyzed and matched with the current operator's permission. Device nodes with matching permissions are selected to generate an initial task list. Then, scheduling optimization is performed based on the estimated task execution time and the personnel's location to generate the final lock control task sequence.

[0045] Step S106: Send the lock control task sequence to the corresponding mobile terminal and receive the task execution status feedback from the mobile terminal.

[0046] In this step, the task sequence is sent to the operator's mobile terminal via wireless network. The operator executes the task according to the terminal prompts, and the terminal uploads task execution status and equipment status change information in real time.

[0047] Step S107: Dynamically update the lock control operation logic diagram according to the task execution status, and adjust the subsequent lock control task sequence.

[0048] In this step, the node status in the lock control operation logic diagram is updated in real time based on the information fed back by the mobile terminal, and the subsequent lock control task sequence is regenerated to form closed-loop management.

[0049] In summary, the method of this application, by constructing an intelligent mechanism for the automatic generation and dynamic adjustment of lock control tasks, realizes closed-loop management of the entire process of substation equipment operation from planning to task execution. This effectively solves problems such as human error in judgment, disconnect between operation plans and on-site conditions, and inefficient access control in traditional lock control management. By collecting equipment operating status data in real time and using a status assessment model for intelligent analysis, the system ensures that lock control tasks are only generated when operating conditions are fully met, significantly improving operational safety and reliability. Furthermore, based on the construction of the lock control operation logic diagram and a fine-grained access control matching mechanism, the system can automatically generate task sequences that match the operator's permissions and dynamically adjust subsequent tasks according to the execution status. This reduces the workload of operators and improves operational efficiency, providing reliable technical support for intelligent operation and maintenance of substations.
