Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flow chart of a power system fault handling aid decision method according to an embodiment of the present invention, and an embodiment of the power system fault handling aid decision method according to the present invention provides an embodiment of the power system fault handling aid 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 may be performed in a sequence different from that here.
The power system fault processing aid decision method provided by the embodiment of the invention comprises the following steps:
step S100, acquiring fault warning information in the power system;
in this step, when a fault occurs in the power system, a fault warning message, for example, a red light alarm is displayed, for example, an alarm is sounded, or the like, may occur. Of course, different fault warning messages may be specifically given according to different fault types and the like. For example, when a large-area device has a power failure, a red fault warning message prompt can be displayed, and if only one device has a power failure, a yellow fault warning message prompt can be displayed. It should be understood that the fault warning message here may be a preset color reminder, a preset sound reminder, or a preset reminder, such as a reminder of major fault, general fault, etc. It should be noted that the failure warning information in the present application is only an example, and the specific configuration is not limited enough, and the failure warning information may be actually configured according to specific requirements. It should be understood that the acquiring of the fault warning information in the power system herein may be actively acquiring fault warning information after a fault occurs in the power system, or acquiring fault warning information after a fault occurs in the power system in real time, or periodically acquiring fault warning information after a fault occurs, or actively reporting after fault warning information is generated after a fault occurs in a device in the power system, and the acquiring manner is not limited in particular.
Further, as shown in fig. 2, fig. 2 is a schematic flow chart of an auxiliary decision method for processing a fault of a power system according to an embodiment of the present invention, where the flow chart further includes, before step S100:
step S600, determining position information of fault warning information;
in this step, in order to facilitate timely processing of the fault warning information in the power system, it is preferable that, when a fault occurs, the location of the fault is located, that is, the location information of the fault warning information is determined, so that rapid processing is facilitated. Specifically, a topological graph of the power system where the fault warning information is located and fault time corresponding to the fault warning information can be obtained at any time; and determining the position information of the fault warning information according to the topological graph of the power system and the fault time. That is, one or more devices with faults can be quickly determined according to the topological graph of the power system, or the topological graph of the power system can be understood to mark each device, when one device or a plurality of devices have faults, fault warning information is displayed on the topological graph, and as the topological graph of each device in the power system is known in advance, the specific actual position of each device can be quickly known when the fault warning information currently appears. Of course, sometimes, because a plurality of devices are connected in parallel or in series, when one of the devices fails, the following device can be driven to fail to work normally, so that the troubleshooting needs to be performed by means of the failure time. It should be understood that the failed device may be quickly located through a topological graph in the power system, and then whether there is a correlation between the failed device or devices may be determined, and if there is a correlation, the determination may be made according to the time of the failure. For example, when a certain device fails first, the subsequent devices stop working, and it is determined whether the association relationship between the devices causes the subsequent devices not to work normally, and the subsequent devices are actually not problematic. For another example, the following device fails first and stops working, and the preceding device stops working after a while, and it is determined that there is no correlation, it is understood that both devices fail. It should be understood that, by using the topological graph of the power system and the fault time corresponding to the fault warning information, the specific fault location information can be quickly realized, which device or devices have a problem can be located, and it is convenient to quickly go to the corresponding device field for device maintenance processing, and it should be understood that the device power fault here is the power fault of the device.
Step S200, extracting fault characteristic information in the fault warning information;
in this step, the fault signature information may 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, and the like. For example, the fault characteristic information may be a fault level, such as a major fault, a general fault, a minor fault, and the like, which is only illustrated by way of example, and may be specific according to an actual situation, for example, the fault level may also be a primary fault, a secondary fault, a tertiary fault, and the like; similarly, the fault signature information may be the cause of the fault, such as a current fault, a voltage fault, a short circuit fault, an overload fault, and the like. Similarly, the fault characteristic information may be a faulty device, such as an office device, a living device, a production device, and the like. Similarly, the fault characteristic information may be a fault code, such as 4545, 3432, 4532, and the like, and it should be understood that corresponding fault information is bound or set in advance for each fault code, for example, 4545 represents that a current fault occurs in the living equipment, 3432 represents that a voltage insufficiency occurs in the production equipment, and 4532 represents that a voltage instability occurs in the production equipment. Similarly, the fault characteristic information may be a type of fault, such as a voltage-type fault, a current-type fault, a short-circuit-type fault, an open-circuit-type fault, and the like. It should be understood that the specific fault feature information may be set and modified according to actual situations, as long as the feature information capable of being identified quickly and being queried can be extracted from the fault warning information conveniently.
Step S300, retrieving a pre-stored historical fault knowledge base according to fault characteristic information, and judging whether a corresponding historical fault processing plan exists in the pre-stored historical fault knowledge base;
specifically, the historical fault knowledge base is prestored through fault characteristic information, and it should be understood that a historical fault processing plan corresponding to the fault characteristic information is stored in the prestored historical fault knowledge base, where the historical fault processing plan may be understood that the same fault occurs before, and fault processing plans given by manual experience or obtained by other means may be referred to as historical fault processing plans, and it may also be understood that fault processing plans corresponding to the fault occurring before the current fault occurs may be referred to as historical fault processing plans. Preferably, the historical fault handling plans in the historical fault knowledge base can be dynamically updated in real time, fault handling plans corresponding to newly-occurring faults in the power system can be stored in the historical fault handling plans, and some stored fault handling plans can be updated according to the latest fault handling plans, such as optimization, replacement, deletion and the like. For example, the device a has a voltage instability fault in 5 months in 2021, the outdoor power supply line is long under normal conditions, or the cross section of the external wire is small, so that the line loss is large, and once a device with large power consumption (such as an induction cooker, a refrigerator, an air conditioner, high-power production equipment and the like) is started, the voltage drop is large, so that the voltage instability is caused. Therefore, the pre-stored historical fault knowledge base has a historical fault processing plan for instable voltage of the equipment A and is provided with the voltage stabilizer.
Specifically, in this step S300, if it is determined that the corresponding historical failure handling plan exists, the historical failure handling plan is presented, that is, the process proceeds to step S400, and if it is determined that the historical failure handling plan does not exist, the process proceeds to step S500.
Step S400, if a corresponding historical fault handling plan exists, displaying the historical fault handling plan;
in this step, the displaying of the historical fault handling plan is understood as displaying the historical fault handling plan to a field processing worker or a command center or the like in various ways. That is to say, the pre-stored historical fault knowledge is stored in the historical fault processing plan corresponding to the fault warning information, and the historical fault processing plan is informed to corresponding personnel, so that the fault can be solved quickly. Compared with the prior art, on-site personnel can not have corresponding experience, and can process the on-site fault according to the historical fault processing plan by means of the displayed historical fault processing plan, so that the fault processing efficiency is improved, the requirement on-site fault processing personnel is reduced, and the overall processing capacity of the power system fault is improved. The historical failure handling plan may be presented by text, by a prepared picture, by a recorded video, or the like, and the specific manner is not limited.
Step S500, if no corresponding historical fault processing plan exists, acquiring auxiliary information corresponding to the fault warning information, wherein the auxiliary information at least comprises simulation information parameters for fault simulation, simulating a fault state corresponding to the fault warning information according to the simulation information parameters, generating a current fault processing plan according to the fault state, and displaying the current fault processing plan;
specifically, in the step, whether a key event is selected is judged, if the key event is selected, key parameter information corresponding to the key event is extracted from the simulation information parameters, the simulated key equipment information and the key time information are determined according to the key parameter information, and the fault state of the key equipment information in the key time information is simulated;
if the key event is not selected, default parameter information corresponding to a preset default option is extracted from the simulation information parameters, simulated default equipment information and default time information are determined according to the default parameter information, and a fault state of the default equipment information in the default time information is simulated.
Optionally, the critical event includes one or more of a failure of a particular device, a failure at a particular time, and a failure at a particular time.
In this step, since the corresponding historical failure processing plan exists in the pre-stored historical failure knowledge base, the current failure processing plan can be obtained by analyzing the current failure according to the acquired auxiliary information.
Optionally, the auxiliary information includes fault inversion information; acquiring auxiliary information corresponding to the fault warning information, and generating a current fault processing plan according to the auxiliary information comprises the following steps: and acquiring fault inversion information corresponding to the fault warning information, generating a current fault processing plan according to the fault inversion information, and displaying the current fault processing plan. In the step, the actual situation of the failed equipment is simulated and restored, the failure problem is found by simulating the actual situation, the current failure handling plan for solving the failure is given, specifically, the key event is firstly determined, for example, the equipment D has the power failure of the equipment, the key event of the failure is firstly determined, the device power failure which appears at 6 am is found through analysis, a time point before and after 6 am is selected as a key event point, the time is determined as the key event point, and then other related or related devices are obtained, then, some equipment and corresponding time nodes which particularly have important influence on the power failure of the equipment D are selected according to the actual situation, the field situation is simulated, the on-site fault inversion is carried out, so that the fault condition can be accurately found. After the field fault inversion is simulated, the fault information can be analyzed, and the current fault processing plan can be determined according to the analysis result. Of course, if the key event point cannot be determined, the operation condition of the device D itself may be simulated, the condition that the device D may handle the power failure is simulated, the corresponding current failure handling plans are given through various conditions, and the current failure handling plans are stored in the pre-stored historical failure knowledge base. It should be understood that, in this step, the power failure cause of some devices cannot be accurately determined due to a special cause, or in order to avoid that some devices cannot timely solve a power failure, a power failure condition of the devices may be simulated, specifically, a single device simulation may be performed, or multiple associated devices may be simulated together, various power failures that may occur are simulated, and a failure processing plan is given according to the simulated power failures, which may prestore a historical failure knowledge base to facilitate rapid subsequent power failures to perform failure processing, or may be rapidly simulated after a device fails and then compared with the occurring failures to determine a failure processing plan.
Optionally, the auxiliary information includes recording information; acquiring auxiliary information corresponding to the fault warning information, and generating a current fault processing plan according to the auxiliary information comprises the following steps: and acquiring wave recording information corresponding to the fault warning information, generating a current fault processing plan according to the wave recording information, and displaying the current fault processing plan. The fault recording is a scheduling end network fault diagnosis system based on fault recording information. The fault recorder is used for a power system, can automatically and accurately record the change conditions of various electrical quantities in the processes before and after a fault when the system has the fault, and has important functions of analyzing and comparing the electrical quantities, analyzing and processing the fault, judging whether protection acts correctly or not and improving the safe operation level of the power system. That is, related information such as a fault reason can be intelligently acquired through fault recording, and a current fault processing plan can be obtained according to the related information. For example, when a fault occurs in a certain device, and the historical fault knowledge base does not have a corresponding historical fault processing plan, a fault record of the device is obtained at the moment, and if the fault record is found to be caused by a short circuit, the processing plan corresponding to the short circuit is generated as a current fault processing plan, and the current fault processing plan is notified to corresponding personnel, so that the fault is solved quickly. Compared with the prior art, on-site personnel can not have corresponding experience, and can process the on-site fault according to the current fault processing plan by means of the displayed current fault processing plan, so that the fault processing efficiency is improved, the requirement on-site fault processing personnel is reduced, and the overall processing capacity of the power system fault is improved. The current failure handling plan may be presented by text, by a prepared picture, by a recorded video, or the like, and the specific manner is not limited.
Optionally, the auxiliary information includes video information; acquiring auxiliary information corresponding to the fault warning information, and generating a current fault processing plan according to the auxiliary information comprises the following steps: and acquiring video information corresponding to the fault warning information, generating a current fault processing plan according to the video information, and displaying the current fault processing plan. For example, after the device C fails and gives a failure warning message, video information corresponding to the device C before and after the failure occurs may be obtained, key information in the video information, such as some information before and after the failure occurs, and it is found that the device C has a power failure due to external dripping entering the device, and then it may be determined according to the video information that the device C has a short circuit due to dripping, and a current failure handling plan for the device dripping short circuit may be given, such as turning off the power of the device, performing a drying process on the device, detecting whether each component of the device is normal after the drying process, if the device is normal, performing an energization process on the device C, if the device is normal after the energization, indicating no problem, and simultaneously storing the current failure handling plan into a pre-stored historical failure knowledge base, if the same situation is met next time, the corresponding video information can be obtained without being associated, and a fault processing plan can be directly given. Therefore, the problem that the fault problem cannot be determined quickly is reduced, the capacity of the whole power system for dealing with the fault can be improved, and the fault solution can be obtained quickly.
Optionally, the auxiliary information includes historical warning information; acquiring auxiliary information corresponding to the fault warning information, and generating a current fault processing plan according to the auxiliary information comprises the following steps: and acquiring historical alarm information corresponding to the fault warning information, generating a current fault processing plan according to the historical alarm information, and displaying the current fault processing plan. For example, in the past history, the number of failures in which a voltage is unstable exceeds 10, the number of failures in short circuit is 1, and the number of other failures is 1. When the equipment E is found to have a fault again, and an alarm is given, and after the fault warning information is obtained, the relevant information of the historical fault is analyzed, so that the high probability that the equipment has unstable voltage is known, and then the processing plan with unstable voltage is shown to field workers as the current fault processing plan, so that the field workers can rapidly process the current fault processing plan.
Further, as shown in fig. 3, fig. 3 is a schematic flowchart of an auxiliary decision method for processing a fault of a power system according to an embodiment of the present invention, where after step S500, the flowchart further includes:
and step S700, performing correlation matching on the current fault processing plan and the fault warning information, and storing the current fault processing plan and the fault warning information into a pre-stored historical fault knowledge base.
In the step, the encountered faults and the corresponding fault processing plans can be stored in the pre-stored historical fault knowledge base in real time, so that the faults which are the same in the subsequent process can be quickly and directly retrieved in the pre-stored historical fault knowledge base, and the fault processing plans can be quickly and simply obtained. It should be understood that the fault handling plan not stored in the pre-stored historical fault knowledge base is taken as the current fault handling plan, and the fault handling plan already stored in the pre-stored historical fault knowledge base is taken as the historical fault handling plan. Of course, these historical fault handling plans not only can directly guide the troubleshooting of field work, but also can reference and assist field faults at intervals.
