[0032] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0033] In the power grid field, grid risks, equipment risks and operational risks will all affect the safety, reliability and stability of the power grid.

[0034] Grid risk refers to the uncertainty of a series of adverse consequences such as power outages and power quality degradation that may occur during the operation of the power system due to the influence of various internal and external factors (load factors, equipment factors), which threaten the safety, reliability and stability of the power grid and may lead to power outages, power quality degradation, etc. It involves all levels of the power grid, including power generation, transmission, transformation, distribution and power consumption.

[0035] Operational risk refers to the risk of personal injury to operators in various operational activities related to the power system (such as grid construction, equipment maintenance, inspection, dispatching, etc.) due to the influence of various factors such as the operating environment and operating procedures. It may also lead to the uncertainty of the operational activities themselves not being completed smoothly or quality problems.

[0036] Equipment risk refers to the risk that various types of equipment in the power system (such as generators, transformers, transmission lines, distribution equipment, etc.) may face the uncertainty of failure, damage, performance degradation, etc. during operation, maintenance, and overhaul due to the influence of multiple factors such as their own performance, external environment, and human operation, which may in turn affect the risk of affecting the function of the equipment itself and the overall operation of the power grid.

[0037] In the existing technology, most of them evaluate the grid risk, equipment risk and operation risk separately, and implement corresponding control strategies according to the evaluation results. That is, the risk control of grid risk, equipment risk and operation risk is monitored separately by different departments.

[0038] However, this method of separately assessing and controlling grid risks, equipment risks, and operational risks has inconsistent data operations and operating platforms. If a risk occurs, it is impossible to identify the related risks it will cause in a linked manner. For example, if an equipment risk occurs, it is impossible to identify the operational risks and grid risks it will cause in a linked manner. There is a lack of unified coordination and integration in the monitoring and control of risks, and a lack of overall risk control, which leads to the underestimation or neglect of certain risk factors, making the risk control efficiency of the grid low.

[0039] In view of this, the present application provides a power grid risk management method, which can conduct risk management of the target power grid by linking power grid risk, operation risk and equipment risk, avoiding the problem of separate assessment and management of power grid risk, equipment risk and operation risk in the prior art, resulting in poor accuracy of risk management, thereby effectively improving the efficiency of power grid risk management.

[0040] The power grid risk management method provided in the present application can be implemented by a computer device, which can be a terminal or a server. The server can be implemented by an independent server or a server cluster composed of multiple servers.

[0041] In an exemplary embodiment, Figure 1 As shown, a power grid risk management method is provided, the method comprising the following steps:

[0042] Step 101: Obtain a work list of the target power grid, and determine initial risk disclosure information based on the work list.

[0043] The work list includes work items to be executed by the target power grid.

[0044] In some exemplary embodiments, the work list can be obtained by performing a "must do" check on the target power grid. Specifically, the work list can be determined based on the unimplemented "must do" work items. The "must do" check refers to checking the work items that the target power grid should and must do.

[0045] For example, after conducting a "must-do" check on the target power grid, assuming it is determined that the target power grid has one of the following problems: equipment defects have not been eliminated, equipment hidden dangers have not been dealt with, special tasks have not been executed, countermeasure tasks have not been executed, maintenance tests have been exceeded, fire risks have occurred, new technologies have been introduced into the network, and spare parts are insufficient, then the work item corresponding to the problem can be stored in the work list.

[0046] Optionally, the risk disclosure information is also a risk disclosure statement, which is used to indicate the response measures for various risks. In some optional embodiments, the computer device can collect the execution status of each response measure in real time and update the corresponding risk level and disposal status.

[0047] In some exemplary embodiments, the work list may be input into a pre-trained initial risk disclosure information determination model to obtain the initial risk disclosure information output by the initial risk disclosure information determination model.

[0048] In other exemplary embodiments, the work items indicated in the work list can also be checked according to the work list to obtain a verification result, and risk monitoring information can be determined based on the verification result; a target baseline / base risk can be determined based on the risk monitoring information and the initial baseline / base risk, and a power outage plan can be generated based on the target baseline / base risk and the working data of the power grid equipment; and the initial risk disclosure information can be determined based on the power outage plan.

[0049] Step 102: Determine a maintenance strategy and a risk warning list for the grid equipment of the target grid based on the grid equipment status monitoring model, and determine target risk disclosure information according to the maintenance strategy and the initial risk disclosure information.

[0050] Optionally, the power grid equipment status monitoring model may be a model pre-trained by a technician according to actual needs. The power grid equipment status monitoring model may be used to monitor the working status of power grid equipment in the target power grid in real time.

[0051] The maintenance strategy is used to instruct a technician to perform maintenance on the power grid device based on the maintenance strategy.

[0052] The risk warning list is used to instruct technical personnel to issue warnings on equipment risks existing in the power grid equipment of the target power grid.

[0053] In some exemplary embodiments, the grid equipment of the target grid can be monitored in real time based on the grid equipment status monitoring model, and the maintenance strategy can be generated according to the monitoring results so that technicians can maintain the grid equipment according to the maintenance strategy.

[0054] Furthermore, the grid equipment of the target grid can be monitored in real time based on the grid equipment status monitoring model, and a risk warning list can be generated according to the monitoring results, so that personnel can issue warnings on equipment risks existing in the grid equipment of the target grid based on the risk warning list.

[0055] As described above, after determining the maintenance strategy and risk warning list for the grid equipment of the target grid based on the grid equipment status monitoring model, the target risk disclosure information can also be determined based on the maintenance strategy and the initial risk disclosure information.

[0056] In some exemplary embodiments, the maintenance strategy and the initial risk disclosure information may be input into a pre-trained target risk disclosure information determination model to obtain the target risk disclosure information output by the target risk disclosure information determination model.

[0057] In other exemplary embodiments, the maintenance strategy may be executed first, and the execution result of the maintenance strategy may be obtained; and the initial risk disclosure information may be adjusted according to the execution result to obtain the target risk disclosure information.

[0058] Step 103: determine a risk monitoring list according to the risk warning list, and perform risk management and control of the target power grid in a linked manner of power grid risk, operation risk and equipment risk based on the risk warning list, the target risk disclosure information and the risk monitoring list.

[0059] Optionally, the risk monitoring list stores items to be detected that require risk monitoring.

[0060] In some exemplary embodiments, the risk warning list may be input into a pre-trained risk monitoring list confirmation model to obtain the risk monitoring list outputted by the risk monitoring list.

[0061] As described above, after determining the risk monitoring list based on the risk warning list, the target power grid can be managed and controlled based on the risk warning list, the target risk disclosure information and the risk monitoring list to link the power grid risk, operation risk and equipment risk.

[0062] Specifically, the management and control strategy can be determined based on the risk warning list. For example, the dispatching department of the target power grid can optimize the operation mode of the target power grid to reduce the level of failure events caused by equipment with equipment risks under normal operation, and prioritize power outage arrangements for equipment with equipment risks to carry out maintenance and inspection of the equipment; the production command centers at all levels of the target power grid can monitor the integrity and timeliness of equipment risks, and monitor whether the power grid management and control measures related to equipment risks are implemented.

[0063] Furthermore, according to the risk monitoring list, the grid equipment affected by the synchronous grid operation and the risk results identified in the basic risk matched by the operation equipment are generated to generate the grid risk consequences involving the equipment. The grid operation risk value is then quantified through the linkage risk value scoring table of grid risk and equipment risk, and the synchronous linkage risk is divided into the personal risk A value and the basic risk B value, and the D value risk is automatically linked and added to the environment, and 1+N operation risk management is performed based on the quantitative results of the linkage addition. Determine the risk response measures based on the target risk disclosure information, and after the response measures are implemented, monitor the implementation of the response measures in real time.

[0064] The above-mentioned power grid risk management method first obtains the work list of the target power grid, and determines the initial risk disclosure information based on the work list, and the work list contains the work items to be executed by the target power grid; then determines the maintenance strategy and risk warning list of the power grid equipment for the target power grid based on the power grid equipment status monitoring model, and determines the target risk disclosure information based on the maintenance strategy and the initial risk disclosure information; finally, determines the risk monitoring list based on the risk warning list, and performs risk management of the target power grid in the linkage of power grid risk, operation risk and equipment risk based on the risk warning list, the target risk disclosure information and the risk monitoring list. The power grid risk management method provided by the present application obtains the risk warning list, the target risk disclosure information and the risk monitoring list through the work list of the target power grid, and performs risk management of the target power grid in the linkage of power grid risk, operation risk and equipment risk through the risk warning list, the target risk disclosure information and the risk monitoring list, thereby avoiding the problem of poor accuracy of risk management in the prior art of separately evaluating and controlling power grid risk, equipment risk and operation risk, thereby effectively improving the efficiency of power grid risk management.

[0065] In an exemplary embodiment, Figure 2 As shown, determining the initial risk disclosure information according to the work list includes the following steps:

[0066] Step 201: Verify the work items indicated in the work list according to the work list to obtain verification results, and determine risk monitoring information according to the verification results.

[0067] In some exemplary embodiments, after the work list of the target power grid is obtained, the work items indicated in the work list may be checked according to the work list, and the checking result may be determined according to whether the work items are executed.

[0068] Furthermore, if there are any unexecuted work items, the risk monitoring information is generated according to the power grid operations and power grid equipment involved in the unexecuted work items.

[0069] Step 202: determine a target baseline / base risk according to the risk monitoring information and the initial baseline / base risk, and generate a power outage plan according to the target baseline / base risk and the working data of the power grid equipment.

[0070] Optionally, the baseline risk refers to the risk based on the standard, including equipment commissioning, equipment retirement, and operation mode change work items. The basic risk refers to the problem-based line of defense, including engineering construction, equipment maintenance, and equipment defect work items.

[0071] In some exemplary embodiments, the initial benchmark / basic risk can be used to identify risks in the target power grid. Specifically, the risks in the equipment commissioning, equipment retirement, and operation mode change of the target power grid can be identified based on the benchmark risk, and the risks in the engineering construction, equipment maintenance, and equipment defect of the target power grid can also be identified based on the basic risk.

[0072] Furthermore, the initial benchmark / base risk may be adjusted based on the risk monitoring information, that is, the risk in the risk monitoring information is also incorporated into the initial benchmark / base risk to obtain the target benchmark / base risk.

[0073] In an optional embodiment of the present application, the target benchmark / base risk can be used to implement pre-control of risks. Specifically, the control strategies related to power grid risks can be updated in conjunction with the adjustment of the initial benchmark / base risk, such as long-term benchmark risk control, such as updating equipment commissioning, equipment retirement, and operation mode changes, and short-term base risk control, such as adjusting engineering construction, equipment maintenance, and equipment defects.

[0074] Optionally, the power outage plan refers to a power outage plan arranged for power grid maintenance / fault repair work on the target power grid. The safety and reliability of the target power grid can be ensured by performing daily maintenance and operation of power grid equipment and upgrading and transformation of the power grid.

[0075] In some exemplary embodiments, after determining the target benchmark / base risk, the initial power outage plan can be adjusted based on the target benchmark / base risk and the operating data of the power grid equipment to obtain the power outage plan, and the adjustment process can be used to optimize the problems existing in the initial plan.

[0076] Step 203: Determine the initial risk disclosure information according to the power outage plan.

[0077] In some exemplary embodiments, since the execution of the power outage plan will cause the target power grid to generate corresponding risks, after the power outage plan is determined, the initial risk disclosure information can be determined according to the power outage plan.

[0078] In an exemplary embodiment, the maintenance strategy and risk warning list for the grid equipment of the target grid are determined based on the grid equipment status monitoring model, including: monitoring the grid equipment based on the grid equipment status monitoring model to generate the maintenance strategy, and generating the risk warning list when the grid equipment status monitoring model detects that the grid equipment is abnormal.

[0079] In some exemplary embodiments, the power grid equipment may be monitored based on the power grid equipment status monitoring model, and a maintenance strategy for the power grid equipment may be generated according to the health and importance information of the power grid equipment.

[0080] Furthermore, in the process of the power grid equipment status monitoring model monitoring the power grid equipment, if an abnormality is detected in the power grid equipment, the risk warning list is directly generated based on the abnormality.

[0081] Specifically, in the process of the power grid equipment status monitoring model monitoring the power grid equipment, if it is monitored that the power grid equipment has defects, hidden dangers, failures and other abnormal phenomena, as well as special projects, countermeasures, maintenance and test overdue and other abnormal situations in equipment management, then the risk warning list can be generated based on the above abnormal situations.

[0082] In an exemplary embodiment, Figure 3 As shown, determining the target risk disclosure information according to the maintenance strategy and the initial risk disclosure information includes the following steps:

[0083] Step 301: Execute the maintenance strategy and obtain the execution result of the maintenance strategy.

[0084] In some exemplary embodiments, after a maintenance strategy for the power grid equipment of the target power grid is generated, the maintenance strategy may be executed by setting a special task, and the execution of the maintenance strategy may be monitored in real time to determine the execution result of the maintenance strategy.

[0085] Step 302: Adjust the initial risk disclosure information according to the execution result to obtain the target risk disclosure information.

[0086] In some exemplary embodiments, after determining the execution result of the maintenance strategy, the initial risk disclosure information can be adjusted according to the execution status of the maintenance strategy. For example, if the execution result of a maintenance strategy is execution failure, it can be determined that the maintenance equipment corresponding to the maintenance strategy is also a risky equipment, and the initial risk disclosure information can be adjusted to add the equipment to the initial risk disclosure information to obtain the target risk disclosure information.

[0087] In an exemplary embodiment, Figure 4As shown, determining the risk monitoring list according to the risk warning list includes the following steps:

[0088] Step 401: Based on a typical fault scenario library, risk identification is performed on the operation items currently operated and maintained by the target power grid to obtain risk identification results.

[0089] Optionally, the typical fault scenarios stored in the typical fault scenario library are fault scenarios caused by power grid operations.

[0090] In some exemplary real-time examples, risk identification is performed on the operation items currently operated and maintained by the target power grid based on the typical fault scenario library to obtain risk identification results. Specifically, an operation risk identification model can be trained based on the typical fault scenario library, and risk identification is performed on the operation items currently operated and maintained by the target power grid based on the operation risk identification model to obtain risk identification results.

[0091] Step 402: Determine the risk monitoring list based on the risk identification result and the risk warning list.

[0092] In an exemplary embodiment, determining the risk monitoring list according to the risk identification result and the risk warning list includes: performing a risk assessment according to the risk identification result, and determining the risk monitoring list according to the risk assessment result and the risk warning list.

[0093] In an exemplary embodiment, Figure 5 As shown, another power grid risk management method is provided, including the following steps:

[0094] Step 501: Obtain a work list of the target power grid, and verify the work items indicated in the work list according to the work list to obtain verification results, and determine risk monitoring information according to the verification results; determine the target baseline / base risk according to the risk monitoring information and the initial baseline / base risk, and generate a power outage plan according to the target baseline / base risk and the working data of the power grid equipment; determine the initial risk disclosure information according to the power outage plan;

[0095] Step 502: monitor the power grid equipment based on the power grid equipment status monitoring model to generate the maintenance strategy, and generate the risk warning list when the power grid equipment status monitoring model detects that the power grid equipment is abnormal;

[0096] Step 503: execute the maintenance strategy and obtain the execution result of the maintenance strategy; adjust the initial risk disclosure information according to the execution result to obtain the target risk disclosure information; perform risk identification on the operation items currently operated and maintained by the target power grid based on the typical fault scenario library to obtain the risk identification result;

[0097] Step 504: perform a risk assessment based on the risk identification result, determine the risk monitoring list based on the risk assessment result and the risk warning list, and perform risk management of the target power grid in conjunction with power grid risk, operation risk and equipment risk based on the risk warning list, the target risk disclosure information and the risk monitoring list.

[0098] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0099] Based on the same inventive concept, the embodiment of the present application also provides a power grid risk control device for implementing the power grid risk control method involved above. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in one or more power grid risk control device embodiments provided below can refer to the limitations of the power grid risk control method above, and will not be repeated here.
