[0041] With reference to the accompanying drawings, the technical solutions in the embodiments of the present application will be clearly and completely described below, obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the present application.
[0042] As shown in Figure 1 , Figure 2 is a flowchart of an embodiment of a power system fault processing auxiliary decision method, and the embodiment of the present application provides an embodiment of a power system fault processing auxiliary decision method, and it should be noted that although a logical sequence is shown in the flowchart, in some cases, the steps shown or described can be performed in an order different from that shown here.
[0043] The embodiment of the present application provides a power system fault processing auxiliary decision method, which comprises:
[0044] Step S100, acquiring fault warning information in the power system;
[0045] In this step, when a fault occurs in the power system, fault warning information will appear, such as displaying a red light reminder, such as sounding an alarm, etc. Of course, different fault warning information can be given according to different fault types, etc. For example, when a large area of equipment appears power failure, red fault warning information can be displayed to remind, and if only one device appears power failure, yellow fault warning information can be displayed to remind. It should be understood that the fault warning information here can be a pre-set color reminder, a pre-set sound reminder, or a pre-set prompt reminder, such as a major fault, a general fault, etc. It should be noted that the fault warning information of the present application is only an example for illustration, and the specific content is not limited, and can be set according to actual needs. It should be understood that the acquisition of the fault warning information in the power system can be active acquisition of the fault warning information after the fault of the power system, real-time acquisition of the fault warning information of the fault in the power system, periodic acquisition of the fault warning information of the fault, or active reporting of the fault warning information generated after the fault of the device in the power system, etc., and the acquisition method does not constitute a specific limitation.
[0046] Further, as shown in Figure 2 , Figure 3 is a flowchart of an embodiment of a power system fault processing auxiliary decision method, and the flowchart further comprises:
[0047] Step S600, determine the location information of the fault warning information;
[0048] In this step, in order to facilitate timely processing of the fault warning information in the power system, preferably, when a fault occurs, the location of the fault is located, that is, the location information of the fault warning information is determined, so as to facilitate rapid processing. Specifically, the power system topology where the fault warning information is located and the fault time corresponding to the fault warning information can be obtained; the location information of the fault warning information is determined according to the power system topology and the fault time. That is, according to the topology of the power system, one or more devices that have failed can be quickly determined, which can also be understood as the topology of the power system marking each device. When one or more devices fail, the topology graph displays the fault warning information. Since the topology of each device in the power system is known in advance, the actual location of the fault warning information can be quickly determined. Of course, sometimes due to the existence of parallel or series connection of multiple devices, when one device fails, the subsequent devices cannot work normally, so the fault time needs to be used for investigation. It should be understood that the topology of the power system can be used to quickly locate the failed device, and then determine whether there is a correlation between one or more devices that have failed. If there is a correlation, the time of the failure can be used to determine. For example, one device fails first, and the subsequent devices stop working, and the correlation is determined. Whether the subsequent devices cannot work normally due to the device, the subsequent devices actually have no problem. For example, the subsequent device fails first and stops working, and the previous device also stops working after a period of time, and it is determined that there is no correlation between them. It can be understood that both devices have failed. It should be understood that the topology of the power system and the fault time corresponding to the fault warning information can quickly determine the location information of the fault, and locate which device or devices have failed, so as to facilitate rapid on-site device maintenance and processing of the corresponding device. It should be understood that the device power failure here refers to the power failure of the device.
[0049] Step S200, extracting fault feature information in the fault warning information;
[0050] In this step, the fault feature information can include the level of the fault, the cause of the fault, the device of the fault, the code of the fault, the category of the fault, etc. For example, the fault feature information can be the level of the fault, such as major fault, general fault, and minor fault, etc. Here, only examples are given, and the specific level of the fault can be determined according to actual conditions, such as first-level fault, second-level fault, third-level fault, etc. Similarly, the fault feature information can be the cause of the fault, such as current fault, voltage fault, short circuit fault, overload fault, etc. Similarly, the fault feature information can be the device of the fault, such as office equipment, living equipment, production equipment, etc. Similarly, the fault feature information can be the code of the fault, such as 4545, 3432, 4532, etc. It should be understood that each fault code is bound or set with corresponding fault information in advance, for example, 4545 represents a current fault of living equipment, 3432 represents a voltage deficiency of production equipment, and 4532 represents a voltage instability of production equipment. Similarly, the fault feature information can be the category of the fault, such as voltage category fault, current category fault, short circuit category fault, and open circuit category fault, etc. It should be understood that the specific fault feature information can be set and modified according to actual conditions, as long as the feature information can be extracted from the fault warning information to quickly identify and facilitate the query.
[0051] In step S300, the pre-stored historical fault knowledge base is retrieved according to the fault feature information, and it is determined whether the corresponding historical fault handling plan exists in the pre-stored historical fault knowledge base.
[0052] Specifically, the pre-stored historical fault knowledge base through the fault feature information should be understood as the pre-stored historical fault knowledge base storing the historical fault handling plan corresponding to the fault feature information. The historical fault handling plan here can be understood as the fault handling plan given by manual experience or obtained by other means when the same fault occurs before, or it can be understood as the fault handling plan corresponding to the fault occurring before the current fault. Preferably, the historical fault handling plan in the historical fault knowledge base can be updated in real time and dynamically, and the fault handling plan corresponding to the newly occurring fault in the power system can be stored therein, or some stored fault handling plans can be updated according to the latest fault handling plan, such as optimization, replacement or deletion, etc. For example, equipment A had a voltage instability fault in May 2021. Under normal circumstances, the outdoor power supply line is long, or the external wire section is small, causing large line loss. Once the equipment with large power consumption is turned on (such as induction cooker, refrigerator, air conditioner, high-power production equipment, etc.), the line voltage drops, causing voltage instability. The solution is to suggest installing a voltage stabilizer. If it is a long-term voltage instability, an automatic step-up and step-down voltage stabilizer is installed. Therefore, the pre-stored historical fault knowledge base stores the historical fault handling plan for voltage instability of equipment A.
[0053] Specifically, in this step S300, if it is judged that the corresponding historical fault handling plan exists, the historical fault handling plan is displayed, that is, it enters step S400, and if it is judged that it does not exist, it enters step S500.
[0054] Step S400, if the corresponding historical fault handling plan exists, the historical fault handling plan is displayed;
[0055] In this step, the historical fault handling plan is displayed, which means that the historical fault handling plan is displayed to the on-site handling personnel or the command center through various means. That is, after determining that the pre-stored historical fault knowledge base has the historical fault handling plan corresponding to the fault warning information, the historical fault handling plan is informed to the corresponding personnel, so as to quickly solve the fault. Compared with the traditional method, the on-site personnel can not have the corresponding experience, and can handle the on-site fault according to the historical fault handling plan by means of the displayed historical fault handling plan. This not only improves the handling efficiency of the fault, but also reduces the requirements for the on-site fault handling personnel, and improves the overall handling capability of the power system fault. The display of the historical fault handling plan here can be the presentation of the historical fault handling plan through text, or the presentation through pictures, or the presentation through recorded videos, etc. The specific mode does not constitute a limitation.
[0056] In step S500, if there is no corresponding historical fault handling plan, auxiliary information corresponding to the fault warning information is acquired, the auxiliary information at least including simulation information parameters used for fault simulation, a fault state corresponding to the fault warning information is simulated according to the simulation information parameters, a current fault handling plan is generated according to the fault state, and the current fault handling plan is presented.
[0057] Specifically, in this step, it is determined whether a key event is selected. If the key event is selected, key parameter information corresponding to the key event is extracted from the simulation information parameters, key equipment information and key time information simulated according to the key parameter information, and a fault state in which the key equipment information appears in the key time information is simulated.
[0058] If the key event is not selected, default parameter information corresponding to a preset default option is extracted from the simulation information parameters, default equipment information and default time information simulated according to the default parameter information, and a fault state in which the default equipment information appears in the default time information is simulated.
[0059] Optionally, the key event includes one or more of a specific equipment failure, a specific time failure, and a specific fault.
[0060] In this step, since the pre-stored historical fault knowledge base has the corresponding historical fault handling plan, a current fault handling plan can be obtained by analyzing the current fault according to the acquired auxiliary information.
[0061] Optionally, the auxiliary information includes fault inversion information; obtaining the auxiliary information corresponding to the fault warning information, and generating the current fault handling plan according to the auxiliary information includes: obtaining the fault inversion information corresponding to the fault warning information, generating the current fault handling plan according to the fault inversion information, and displaying the current fault handling plan. In this step, the actual situation of the device that has failed is simulated to restore it, the fault problem is found by simulating its actual situation, the current fault handling plan for solving the fault is given, and specifically, the key event is first determined, for example, the device D has a device power failure, the key event of its failure is first determined, it is found through analysis that it is a device power failure that occurs at 6 o'clock in the morning, at this time a time point before and after 6 o'clock in the morning is selected as the key event point, after determining the time as the key event point, the associated or related other devices are obtained, and then according to the actual situation, some devices and corresponding time nodes that are important to the power failure of the device D are selected, the on-site situation is simulated, and the on-site fault inversion is performed, so that the failure situation can be accurately found. After simulating the on-site fault inversion, the fault information can be analyzed, and the current fault handling plan is determined according to the analysis result. Of course, if the key event point cannot be determined, the operation of the device D itself can also be simulated to simulate the possible power failure situation of the device D, and the corresponding current fault handling plan is given through various situations, and these current fault handling plans are stored in the pre-stored historical fault knowledge base. It should be understood that in this step, due to special reasons, the power failure reason of some devices cannot be accurately determined, or in order to avoid that some devices cannot be timely solved due to power failure, the power failure situation of the device can be simulated, specifically, a single device can be simulated or multiple associated devices can be simulated together, various possible power failures are simulated out, and the fault handling plan is given according to the simulated power failure. These fault handling plans can be pre-stored in the historical fault knowledge base to facilitate subsequent fault handling of power failure, or the device can be quickly simulated after the device fails, and then the fault handling plan is determined by comparing with the occurred fault.
[0062] Optionally, the auxiliary information includes recording wave information; the auxiliary information corresponding to the fault warning information is acquired, and the current fault handling plan is generated according to the auxiliary information, including: the recording wave information corresponding to the fault warning information is acquired, the current fault handling plan is generated according to the recording wave information, and the current fault handling plan is displayed. The fault recording is a kind of dispatching end power grid fault diagnosis system based on fault recording information. The fault recorder is used in the power system, which can automatically and accurately record the change of various electrical quantities before and after the fault when the system fails, and through the analysis, comparison of these electrical quantities, the analysis and processing of the accident, the judgment of whether the protection is correctly operated and the improvement of the safe operation level of the power system have important role. That is, the fault reason and other related information can be intelligently obtained through the fault recording, and the current fault handling plan is obtained according to the related information. For example, a device fails, and there is no corresponding historical fault handling plan in the historical fault knowledge base. At this time, the fault recording is obtained, and it is found that it is caused by short circuit. Then the handling plan corresponding to the short circuit is generated as the current fault handling plan, which informs the corresponding personnel of the current fault handling plan, so as to quickly solve the fault. Compared with the traditional method, the on-site personnel can not have corresponding experience, can rely on the current fault handling plan displayed, and can handle the on-site fault according to the current fault handling plan. Not only the fault handling efficiency is improved, but also the requirement for the personnel handling the on-site fault is reduced, and the overall processing capability of the power system fault is improved. The current fault handling plan displayed here can be presented by text, picture or video, and the specific mode does not constitute limitation.
[0063] Optionally, auxiliary information includes video information. Obtaining auxiliary information corresponding to fault warning information and generating a current fault handling plan based on that information includes: obtaining video information corresponding to the fault warning information, generating a current fault handling plan based on the video information, and displaying the current fault handling plan. For example, when device C malfunctions and issues a fault warning, the video information corresponding to the events before and after the malfunction can be obtained. Key information can be extracted from the video information, such as information about the events before and after the malfunction. If it is found that device C's power failure is due to external water dripping into the device, then based on this video information, it can be determined that the short circuit is caused by the water dripping. A current fault handling plan for the water dripping short circuit can be provided, such as cutting off the device's power supply, drying the device, and then checking the functionality of each component after drying. If everything is normal, device C is powered on again. If the device operates normally after powering on, then there is no problem. This current fault handling plan is stored in a pre-stored historical fault knowledge base. If the same situation is encountered again, it is not necessary to retrieve the corresponding video information again; the fault handling plan can be directly provided. This not only reduces the number of problems that cannot be quickly identified, but also improves the entire power system's ability to cope with faults and quickly obtain solutions to them.
[0064] Optionally, auxiliary information includes historical alarm information. Obtaining auxiliary information corresponding to fault warning information and generating a current fault handling plan based on this information includes: obtaining historical alarm information corresponding to the fault warning information, generating a current fault handling plan based on the historical alarm information, and displaying the current fault handling plan. For example, device E has experienced more than 10 instances of voltage instability, 1 instance of short circuit, and 1 instance of other faults in its history. When device E is found to have a fault again and triggers an alarm, after obtaining its fault warning information, analysis of its historical fault information reveals that it is likely due to voltage instability. Therefore, the voltage instability handling plan is presented as the current fault handling plan to the on-site personnel, facilitating rapid response.
[0065] Furthermore, such as Figure 3 As shown, Figure 4 This is a flowchart illustrating a power system fault handling auxiliary decision-making method according to an embodiment of the present invention. After step S500, the flowchart further includes:
[0066] Step S700: Associate and match the current fault handling plan and fault warning information, and store them in the pre-stored historical fault knowledge base.
[0067] In this step, the encountered failure and the corresponding failure handling plan can be stored in the pre-stored historical failure knowledge base in real time, so that when the same failure is encountered subsequently, the pre-stored historical failure knowledge base can be directly searched for, and the failure handling plan can be quickly and simply obtained. It should be understood that, for a failure handling plan that is not in the pre-stored historical failure knowledge base, the failure handling plan is taken as a current failure handling plan, and for a failure handling plan that has been stored in the pre-stored historical failure knowledge base, the failure handling plan is taken as a historical failure handling plan. Of course, these historical failure handling plans can not only directly guide the troubleshooting of the on-site work, but also can be used as a reference for the on-site failure.
[0068] In addition, the application also provides an electric power system failure handling auxiliary decision device, as shown in the accompanying drawings. Figure 5 As shown in the accompanying drawings, the electric power system failure handling auxiliary decision device comprises:
[0069] An acquisition module is configured to acquire failure warning information in an electric power system.

[0072] A historical plan module is configured to, if the corresponding historical failure handling plan exists, display the historical failure handling plan.
[0073] A current plan module is configured to, if the corresponding historical failure handling plan does not exist, acquire auxiliary information corresponding to the failure warning information, the auxiliary information at least comprising simulation information parameters used for failure simulation, simulate a failure state corresponding to the failure warning information according to the simulation information parameters, generate a current failure handling plan according to the failure state, and display the current failure handling plan.
[0074] Compared with the prior art, the electric power system failure handling auxiliary decision device provided by the application mainly solves the problems of difficult failure positioning analysis in an electric power system, inaccurate confirmation of a failure, and finding of a suitable solution to the failure. The method or device and the equipment provided by the application can greatly improve the efficiency of failure positioning and problem handling in the electric power system. On-site failure handling no longer relies on personal experience, and the entire failure positioning and failure handling has a complete process and handling plan. The failure handling in the electric power system is processed in a process and programmed, so that the probability of human error is reduced. Through analysis and practice, the efficiency of failure handling is improved through the present solution.

[0076] Specifically, the positioning module is configured to obtain a power system topology where the fault warning information is located and a fault time corresponding to the fault warning information, and determine the position information of the fault warning information according to the power system topology and the fault time.
[0077] In addition, the present application further provides a power system fault processing auxiliary decision device, which comprises: As shown, the power system fault processing auxiliary decision device further comprises an updating module, which is configured to associate and match the current fault processing plan and the fault warning information after generating the current fault processing plan according to the auxiliary information and presenting the current fault processing plan, and store the current fault processing plan and the fault warning information in the pre-stored historical fault knowledge base.
