For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. Among them:

[0028] Figure 1 An overall flow chart of a collaborative control method for automatic fault handling provided in the first embodiment of the present invention. DETAILED DESCRIPTION

[0029] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without creative work should fall within the scope of protection of the present invention.

[0030] Example 1, reference Figure 1 According to an embodiment of the present invention, a method for automatic fault handling and coordinated control is provided, comprising:

[0031] The present invention uses the automatic driving function of the fault log, which runs through the provincial distribution network OMS, the provincial network command system, and the municipal bureau OCS system, breaks through the system interaction barriers and ultimately realizes the full-process intelligent execution and full-process monitoring of the fault log automatic driving work.

[0032] Use the collaborative interface between the provincial distribution network OMS and the municipal bureau OCS system to transfer the fault log work order and brief work order information from the distribution network OMS system to the municipal bureau distribution network OCS system. Click the single line diagram to generate a programmed item-by-item order or instruction based on the fault log and other business document information. In the distribution network OMS system pushed after the municipal bureau OCS successfully completes the ticket,

[0033] The distribution network OMS system automatically links the programmed item-by-item commands or instructions with the corresponding fault log work orders, and coordinates the programmed operation commands for power outage operations, programmed operation commands for power restoration operations, programmed operation commands for transfer-out operations, and programmed operation commands for transfer-in operations to the fault log business work order business module. The corresponding programmed tickets are subject to three reviews, and during the monitoring review stage, they interact with the distribution network OCS to verify the equipment status. The programmed operation commands that have passed the three reviews have the basic programmed operation conditions, and the ticket preparation work is completed.

[0034] Task scheduling is carried out according to steps such as load transfer, power outage operation, start-up application, permission to start work, completion application, permission termination, power restoration operation, and load restoration, and in accordance with the operation items involved in the actual work.

[0035] In task association, the tasker can start the automatic driving of the fault log, and the automatic driving of the fault log starts to execute automatically. The execution progress, intelligent command abnormal monitoring and operation status link monitoring can be viewed in real time in the whole process intelligent monitoring.

[0036] Equipment safety logic verification:

[0037] Error prevention check function strategy error prevention: when the operation simulation is executed, topology error prevention, loop flow verification error prevention and operation logic rule error prevention are carried out. In the OMS system: (1) After the ticket is generated in the point diagram ticket module, click preview. (2) The operation ticket that has passed the preview and the third review enters the programmed operation part. In the OCS system: (1) Topology error prevention check: check abnormal operations such as closing the switch with grounding, closing the knife switch with grounding, closing the knife switch with power on, closing the grounding switch (ground knife) with power on, and closing the grounding switch (ground knife) with knife switch. It can automatically perform a comprehensive error prevention check on the operator's operation based on the topological relationship of the power grid, combined with user-defined rules, and based on the real-time telesignaling and telemetry information of the steady-state data monitoring application. (2) Loop flow verification: the impact current and steady-state current do not exceed the limit; the operation process does not allow more than two lines to close the loop at the same time; the operation process requires closing the loop first and then opening the loop. (3) Operation rule verification: in order to prevent operations not being performed in the order of the operation ticket, the system provides an operation sequence verification function.

[0038] Equipment consistency check: During the operation simulation, check the equipment card name, GISID, equipment name on the operation ticket, and other information. If there is any inconsistency, a prompt will be output. In the OMS system: (1) After the ticket is generated in the point-to-point ticket module, click Preview to output the equipment parameter information. (2) Perform a third review of the ticket. (3) The dispatcher reviews it, manually modifies it, and clicks Preview to enter the 1st loop. In the OCS system: (1) Check the equipment card name, GISID, equipment name on the operation ticket, and other information: Check for consistency. If there is any inconsistency (output the reason).

[0039] Equipment consistency check: Automatically determine whether there is a power transfer operation in the operation ticket. If there is a power transfer, automatically identify the operating mode of the two lines, and determine whether the conditions for loop closing are met based on preset conditions such as flow and power grid parameters. If the conditions for loop closing are met, automatically prompt to modify the operation ticket to loop closing and power transfer. In the OMS system: (1) If the OCS output can close the loop, the dispatcher asks the site whether the conditions for loop closing are met and then clicks the rehearsal link loop, (2) enters the programmed operation part. In the OCS system: (1) The point-to-map ticket module selects to adjust the rear section of a certain line to a certain pole to be powered by a certain line, automatically determines whether the loop closing and power adjustment can be output to OMS, and generates the corresponding ticket. (2) Output the rehearsal results.

[0040] Remote control operation error prevention: During the remote control execution of programmed operations, the status of the remotely controlled equipment and the flow check are checked before the remote control is executed, and the switch is automatically judged to have abnormal information such as abnormal information of the sign hanging and closing the loop after remote control. In the OMS system: (1) The remote control operation command required in the network command is sent to the OCS: After receiving the remote control success information, proceed to the next step; after receiving the remote control failure information, the dispatch order is transferred to the on-site operation and the on-site operation is ordered after three reviews. In the OCS system: (1) The telemetering and telesignaling check whether the remote control is possible, and the remote control is automatically disconnected / closed after confirming that the remote control is possible. (2) The remote control result is checked according to the telemetering and telesignaling current and other parameters. Remote control success; remote control failure (output the reason, and automatically form the automatic switch remote control failure account). When the control is closed, check: (1) If there is only a G011 disconnector, the normal operation mode detects whether there is pressure on the power supply side before closing (2) If there are disconnectors on both sides, both can be closed only when there is pressure. When the control is divided, check: (1) If there is a fault defect, the network command on the on-site end pops up whether to notify the user, and the emergency repair personnel selects yes and then automatically disconnects.

[0041] Live earthing / grounding switch verification: Check data: read switch position, whether the switch is disconnected before turning on the maintenance and closing the earthing switch, whether the isolation switch is opened, and whether there are other power supply points (contact switch, small power plant). Data acquisition system: OCS system, OMS system power management module and ticket logic.

[0042] Verification of power transmission with ground wire, verification data: read the grounding card, read the ticket to see if all "...transfer to maintenance" have corresponding "transfer to maintenance..."; verification of circuit breakers with incorrect opening and closing, verification data: OCS verifies before remote control; single-step verification in ticket opening, ticket review, and execution status, verification data: add verification buttons to instructions (fault defects) and instruction groups, and support safety logic verification. Data acquisition system: OCS system and ticket logic.

[0043] B. Automatic driving of distribution network fault log service (see the attached Figure 1 ):

[0044] General principles: Based on the safety logic verification settings, the system automatically reviews, processes, and permits the start and completion applications of faulty businesses, and automatically stops and reminds the dispatcher in the event of an abnormality. The reminder functions of the on-site and dispatching ends are optimized, combined with the intelligent network command function, to ultimately achieve full-process intelligent execution of the faulty business after the fault point is found.

[0045] Source of fault log data: The intelligent alarm module in the distribution network OMS system automatically generates fault logs by publishing equipment alarm information, or the dispatcher manually adds fault logs based on equipment fault information in the OCS system.

[0046] In the distribution network OMS fault log work order details, click OCS ticketing for each link and module, and generate a ticketing request based on the basic information of the work order. The distribution network OMS transmits the fault log work order and brief information to the distribution network OCS system through the interface.

[0047] In the distribution network OCS system, based on the distribution network log work order information, compare it with the detailed fault information of the equipment in the fault log, and according to the equipment fault handling requirements, click on the single-line diagram to generate various types of programmed operation tickets or programmed instructions.

[0048] The programmed ticket generated by the OCS system is sent to the programmed operation control module of the distribution network OMS system through the interface between systems, and the programmed operation ticket is automatically associated with the distribution network fault log work order in the distribution network OMS. The programmed instructions for handling faulty equipment are also subject to three reviews in the OMS system to confirm that the invoicing information meets the fault requirements, and at the same time, the equipment information involved in the remote control item is verified to ensure the feasibility of remote control operation and the safety of equipment and personnel.

[0049] During equipment verification: the distribution network OMS sends the equipment status request information in the remote control item to the OCS, performs a programmable operation requirement check in the distribution network OCS system, and sends the equipment status check information to the distribution network OMS. The distribution network OMS system sends a programmable operation instruction to the distribution network OCS system through the interface, and the distribution network OCS system verifies it after receiving it. If it meets the operation requirements, the programmable ticket is approved and the ticket preparation operation is completed.

[0050] After completing the various ticket preparation operations for fault handling, it is necessary to arrange the tasks of autonomous driving according to the business operation items involved in the fault log. After completing the task arrangement, the fault log autonomous driving can be started within the planned time. According to the task arrangement, the fault log autonomous driving is automatically executed, and the whole process is intelligently monitored to check the execution progress and whether there are any abnormalities.

[0051] During the execution of autonomous driving, the system pushes reminders of various operation information on the on-site and dispatching ends in real time. Various programmed operation tickets and instructions are intelligently issued through the network and automatically notified for execution according to the set planned operation time. All aspects of the execution are fully intelligently monitored, such as various execution information, abnormal information, etc.

[0052] Embodiment 2 is an embodiment of the present invention, which provides a system for a collaborative control method for automatic fault handling, including: a fault log management module, an instruction generation and transmission module, a safety verification and triple review module, and a task scheduling and monitoring module.

[0053] The fault log management module generates fault logs. In the distribution network OMS system, fault logs are generated through an automated alarm mechanism, or manually created by the dispatcher in the OCS system.

[0054] The instruction generation and transmission module transmits the fault log work order and brief information from the provincial distribution network OMS system to the municipal bureau OCS system, and generates item-by-item programmed operation instructions based on the fault content. The programmed instructions are formed by clicking on the single-line diagram, and the instructions are transmitted to the fault log work order in the distribution network OMS system.

[0055] The safety verification and triple review module is responsible for safety logic verification, equipment status verification and operating condition verification. Before the operation instruction is executed, the grid topology is analyzed, the loop flow situation is identified, and it is determined whether the operation will cause current shock or steady-state current exceeding the limit. The equipment card name, GISID and equipment name on the operation ticket are compared, and the equipment status is checked to see if it is consistent with the operation requirements. The equipment switch operation authority, working status and specific requirements of the operation ticket are checked to ensure that the operation meets the execution conditions.

[0056] The task scheduling and monitoring module schedules power outage operations, work permits, completion applications, and power restoration operations according to task steps, and establishes task nodes through dependency associations to ensure that each task is automatically executed in sequence.

[0061] Embodiment 3: In this embodiment, in order to verify the beneficial effects of the present invention, scientific demonstration is carried out through economic benefit calculation and simulation experiments. This embodiment experiments the existing traditional method and the method of this embodiment respectively.

[0062] Verify the scheduling efficiency and execution cost of the automatic fault handling collaborative control method of the present invention under different task loads, and analyze its performance advantages in real-time monitoring and intelligent task scheduling.

[0063] To compare the method of the present invention with the traditional manual operation method, the following three experiments were conducted:

[0064] Under the same task request, the load balancing rates of different methods in a multi-task environment are compared, the average execution time of tasks is recorded under different numbers of repetitions, and the execution costs of each method are compared under different numbers of tasks.

[0065] The experiment was conducted in a simulated distribution network system, simulating common fault types and dispatching operations, including power outage operations, start-up applications, completion permits, and power restoration operations.

[0066] Table 1 Task load balancing rate comparison table

[0067]

[0068] Under 50 identical task requests, the traditional manual operation method and the automatic handling method of the present invention were applied respectively, and the load balancing rate was recorded. The load balancing rate of the traditional manual operation method fluctuated between 60% and 70%, and some task nodes were prone to overload; while the load balancing rate of the method of the present invention was stable at more than 90%, significantly improving the distribution balance of tasks.

[0069] Table 2 Task execution time comparison table

[0070]

[0071] The average execution time of the two methods was recorded under the conditions of 20, 50 and 100 task repetitions.

[0072] When the task is repeated 20 times, the average execution time of the method of the present invention is 30 seconds, while that of the traditional method is 50 seconds; when the task is repeated 100 times, the execution time of the method of the present invention is stable at about 35 seconds, while that of the traditional method is extended to more than 70 seconds. The present invention shows higher execution efficiency in the case of highly repeated tasks.

[0073] Table 3. Comparison of task execution costs

[0074]

[0075] The execution costs of the two methods were calculated under 20, 40, 60, 80 and 100 tasks (estimated by man-hours and power consumption). As the number of tasks increases, the execution cost of the traditional method increases linearly, while the execution cost of the method of the present invention increases slightly. Under a high-load environment of 100 tasks, the execution cost of the method of the present invention is about 60% of that of the traditional method, effectively reducing labor costs and resource consumption.
