Description

Technical Field

[0001] The present invention relates to the technical field of power system inspection, and in particular to an inspection method, device, terminal equipment and storage medium based on alarm information. Background Art

[0002] During power system operation, equipment anomalies generate alarms. To ensure stable power system operation, relevant equipment must be inspected and monitored based on these alarms. However, traditional inspection schemes often employ fixed patterns. For example, they do not differentiate between alarm levels or consider the relationships between devices. Regardless of the alarm level or device relationships, inspections are conducted according to uniform standards to monitor equipment operation.

[0003] However, for critical or serious alarms, a fixed number of inspections may not be enough to detect equipment hazards in a timely manner, because high-level alarms usually indicate that the equipment is at risk of serious failure and requires more frequent and comprehensive monitoring. Therefore, the existing technology cannot deepen the intensity or scope of inspections according to the severity of the alarm, resulting in the inability to detect and deal with serious failure hazards in a timely manner. Summary of the Invention

This target patrol number is greater than the initial patrol number, thereby increasing the patrol frequency. Furthermore, devices connected to the first device are included in the monitoring scope as second devices, expanding the patrol scope.

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0055] like Figure 1 As shown, in order to solve the problem in the prior art that the intensity or scope of inspection cannot be deepened according to the severity of the alarm, resulting in the inability to timely discover and deal with serious potential faults, an embodiment of the present invention provides an inspection method based on alarm information, including:

[0056] Step S1: Acquire alarm information corresponding to the power system and the alarm level corresponding to the alarm information; wherein the alarm information corresponds to an initial patrol plan; the initial patrol plan includes: the number of initial patrols and a number of first devices whose operating status needs to be monitored; the alarm level is: general alarm, critical alarm or severe alarm;

[0057] Illustratively, the present invention can obtain alarm information from power system automation equipment (such as protection devices and measurement and control devices) in real time, and can classify the alarms into three levels according to their impact range and urgency:

[0058] General alarm: has little impact on system operation (such as a slight temperature rise of the equipment); serious alarm: may cause local failure (such as an abnormality of a single protection plug-in); critical alarm: directly threatens system stability (such as busbar differential current exceeding the limit).

[0059] In addition, an initial patrol plan can be bound to each alarm, including: the initial patrol number, such as the regular monitoring frequency (such as once a week for general alarms); and the first device, that is, the device that directly generates the alarm (such as a line protection device).

[0060] Step S2: When it is determined that the alarm level is a general alarm, the initial patrol plan is used as a target patrol plan for monitoring the operating status of the equipment;

[0061] When the alarm level is determined to be a critical alarm or a severe alarm, a target patrol number is generated based on a preset number multiple and the initial patrol number; a device connected to the first device is used as a second device whose operating status needs to be monitored; and a target patrol plan is generated based on the target patrol number, each first device, and each second device; wherein the target patrol number is greater than the initial patrol number;

[0062] Illustratively, the embodiment of the present invention can generate a response target patrol plan according to the alarm level. For an alarm level of general alarm, the initial patrol plan is directly used to maintain regular monitoring intensity.

[0063] For severe / critical alarms, the frequency of patrols is increased, for example, target patrol times = initial patrol times × preset times (e.g. severe alarm × 2, critical alarm × 3). If the initial patrol frequency is once a week, it is adjusted to once a day for critical alarms, which can strengthen high-frequency monitoring.

[0064] Furthermore, the monitoring scope can be expanded, that is, the second device that is connected to the first device can be included in the monitored device scope, and the multiplied number of times and the expanded device list can be integrated to form an enhanced inspection plan for high-risk alarms and obtain a target inspection plan.

[0065] Step S3: patrol the equipment in the power system according to the target patrol plan.

[0066] Illustratively, when patrolling based on the target patrol plan, the operating status or operating conditions of the first device and the second device may be monitored according to the frequency of the target plan.

[0067] For step S1, in a preferred embodiment, the alarm information corresponding to the power system is the alarm information of the protection device in the power system, and different protection device models have different corresponding alarm information.

[0068] For different types of protection devices, when an alarm is triggered, the affected protection plug-ins can be determined, and the current alarm level can be calculated based on the number of affected protection plug-ins. Furthermore, the protection device can be bound to an initial inspection plan, such as the inspection cycle and the inspection content (for example, which parts need to be inspected and monitored).

[0069] Therefore, when obtaining the alarm information of a certain protection device, the alarm level corresponding to the alarm information can be obtained based on the number of affected plug-ins mentioned in the alarm information, and the initial inspection plan corresponding to the alarm information can be extracted, so as to carry out the next level judgment to determine whether to adjust the inspection plan.

[0070] For step S2, the present invention can determine whether to adjust the inspection plan based on the severity level of the alarm. Since the alarm levels are divided into three categories: general alarm, critical alarm and serious alarm, when the level of the received alarm is critical or serious, the present invention can increase the intensity of the inspection and the monitoring range, thereby obtaining a new inspection plan, namely the target inspection plan.

[0071] In a preferred embodiment, the present invention can obtain the second device when expanding the monitoring list of the device. The specific process can be:

[0072] For each first device, when it is determined that the first device is a device in the bus, a device connected to the bus to which the first device belongs is used as a second device;

[0073] When it is determined that the first device is a device in a transmission line, a device connected to the same transmission line in an opposite substation is used as a second device according to the transmission line to which the first device belongs;

[0074] When it is determined that the first device is a communication device in the power system, the second device is not generated.

[0075] It is understood that a busbar connects many devices, such as the incoming and outgoing lines of various transmission lines, transformers, and so on. If the first device is a busbar device, such as a busbar protection device, then the protection devices of all transmission lines and transformers connected to this busbar can serve as the second device. Because a busbar fault may affect all connected devices, the present invention can monitor these associated devices to fully understand the operating status of the power system and promptly detect potential hidden faults.

[0076] Furthermore, when the first device is a device in a transmission line, then: if there is a transmission line connecting substation A and substation B. If in substation A, the protection device (first device) of a transmission line issues an alarm or is the first device that needs to be monitored, then in substation B, the protection device, measurement and control device, etc. connected to this transmission line will be determined as the second device. Since a transmission line is a whole, the devices at both ends are interrelated. When a problem occurs at one end, the device at the other end may also be affected or there may be potential causes of failure. Therefore, when generating a target inspection plan, the present invention can more comprehensively troubleshoot faults and improve the accuracy of fault diagnosis by monitoring the equipment on the same transmission line of the opposite substation.

[0077] Furthermore, communication equipment is mainly responsible for data transmission and communication functions in the power system. Although the failure of communication equipment may affect the data interaction of other equipment, its connection relationship with other equipment is relatively independent. Unlike busbar equipment and transmission line equipment, there is no direct electrical connection and mutual influence. Therefore, when the first device is a communication device in the power system, not generating a second device can avoid unnecessary expansion of the monitoring scope and improve the targetedness and efficiency of monitoring.

[0078] Therefore, the embodiment of the present invention can comprehensively monitor the second device related to the first device and potentially have potential fault hazards by determining the second device in the above manner. Whether it is busbar equipment or transmission line equipment, other connected equipment is taken into account, thus expanding the monitoring scope and facilitating the discovery of potential hidden faults.

[0079] Furthermore, after obtaining the second device, the final target inspection plan can be obtained based on the first device, the second device and the newly obtained target inspection number. The specific process is as follows:

[0080] Obtaining parameter values ​​of each first device and each second device respectively; wherein the parameter values ​​are used to verify whether the operating parameters of the devices are abnormal;

[0081] Taking an analog quantity of each first device and a state quantity of each first device as a first parameter to be monitored; wherein the analog quantity is used to characterize an operating parameter of the device, and the state quantity is used to characterize a device state of the device;

[0082] Taking the analog quantity of each second device and the state quantity of each second device as the second parameter to be monitored;

[0083] The target patrol times are used as the monitoring times of each first parameter to be monitored and each second parameter to be monitored;

[0084] A target patrol plan is generated according to each first parameter to be monitored, each second parameter to be monitored, each parameter constant value and the number of monitoring times.

[0085] Specifically, the embodiment of the present invention takes into account various factors related to alarms in the power system, including analog quantities, state quantities, and parameter values ​​of the first device and the second device, and sets a clear monitoring number for each parameter to be monitored.

[0086] The targeted inspection scheme derived from this invention can monitor equipment from multiple dimensions to fully understand its operating status. For example, it not only focuses on the equipment's current operating parameters (analog quantities) and status (status quantities), but also considers the standard parameters for normal equipment operation (parameter values). During inspections, the parameter values ​​can be compared with actual operating data to more accurately determine whether the equipment is experiencing an anomaly.

[0087] Illustratively, in an embodiment of the present invention, a target patrol number can be assigned to each first parameter to be monitored and each second parameter to be monitored as their respective monitoring times. Since the target patrol number is determined based on the alarm level, when the alarm level is critical or severe, the patrol number will be increased accordingly, thereby strengthening the monitoring of the equipment. For example, if the target patrol number is set to once every 2 hours, then for each first parameter to be monitored and each second parameter to be monitored, data collection and analysis will be performed at this frequency to timely capture changes in the equipment's operating parameters and status.

[0088] For step S3, in a preferred embodiment, after the target patrol plan is obtained, the analog quantities (such as current, voltage), state quantities (such as switch position, pressure plate status), and constants (such as protection thresholds) of the first device and the second device can be monitored according to the frequency of the target plan to realize the patrol of the equipment in the power system.

[0089] Furthermore, after inspecting the equipment in the power system according to the target inspection plan, the present invention further includes:

[0090] An inspection report is generated according to the operating data of the first device or the second device during the execution of the target inspection plan.

[0091] The embodiment of the present invention can collect the operating data of the first device or the second device during the execution of the target patrol plan, and compare the collected analog quantity with the corresponding reference constant to identify whether the analog quantity exceeds the limit or whether the change trend of the analog quantity is abnormal, thereby generating an inspection report.

[0092] Specifically, the present invention can also verify whether the status quantity of the first device or the second device is consistent with the corresponding reference value, such as whether the actual state of the soft pressure plate is consistent with the master station instruction, etc., thereby generating a corresponding inspection report based on the comparison results of the analog quantity and the device status consistency results. For example, abnormal equipment and risk levels can be marked in the inspection report, and an alarm or maintenance work order can be triggered.

[0093] In a preferred embodiment, the alarm information of the present invention can be divided into two types: one is a state quantity alarm, and the other is an analog value over-limit alarm. The first type of alarm, used to indicate abnormalities in the device status, is a state quantity alarm; the second type of alarm, used to indicate abnormalities in the device electrical parameters, is an analog value over-limit alarm.

[0094] In a preferred embodiment, when the alarm type of the alarm information is the first alarm type, the process of generating the inspection report is specifically as follows:

[0095] Acquire analog quantity change data of the first device or the second device during execution of the target patrol plan;

[0096] Constructing a corresponding analog quantity trend curve based on the analog quantity change data; wherein the analog quantity trend curve is used to describe the change trend of the analog quantity over time;

[0097] According to the analog quantity trend curve, determining whether the change rate of the analog quantity within a preset time window is greater than a preset change rate;

[0098] If so, an inspection report is generated to indicate potential risks in the equipment's operating performance;

[0099] If not, an inspection report is generated to indicate that there are no hidden dangers in the operating performance of the equipment.

[0100] In a preferred embodiment, when the alarm type of the alarm information is the second alarm type, the process of generating the inspection report is specifically as follows:

[0101] Acquire analog quantity change data of the first device or the second device during execution of the target patrol plan;

[0102] Constructing a corresponding analog quantity trend curve based on the analog quantity change data; wherein the analog quantity trend curve is used to describe the change trend of the analog quantity over time;

[0103] According to the analog quantity trend curve, determining whether the change rate of the analog quantity within a preset time window is greater than a preset change rate;

[0104] If so, an inspection report is generated to indicate potential risks in the equipment's operating performance;

[0105] If not, an inspection report is generated to indicate that there are no hidden dangers in the operating performance of the equipment.

[0106] It can be understood that the present invention can realize two inspection report generation methods for different alarm types. Schematically, for the status alarm type, when generating the inspection report, the actual value of the equipment status can be compared with the standard value (such as the soft pressure plate should be put into operation but is not put into operation) to directly determine whether there is a configuration risk. No trend analysis is required, and only a single status check is required to generate the inspection report. It can also trigger an alarm (such as "the control pressure plate is actually exited, and the standard value should be put into operation"). The embodiment of the present invention can then determine whether there is a hidden fault based on the content of the inspection and trigger the next alarm.

[0107] In a preferred embodiment, the present invention can be applied to a system primarily composed of a main operation and maintenance station, sub-operation and maintenance stations, protection devices, measurement and control devices, intelligent terminals, and other automated equipment. The main operation and maintenance station primarily receives alarms from the devices, the sub-stations primarily forward alarm information from the protection devices, and the protection devices primarily collect on-site information.

[0108] like Figure 2 As shown in the flowchart of the status alarm type, after the operation and maintenance main station receives the status alarm information, it can locate and search the mapping relationship table, which records the correspondence between the alarm-related equipment and other information, so that a preliminary inspection plan can be generated based on the content in the mapping relationship table.

[0109] Determine the alarm level to distinguish whether it is a general alarm, a critical alarm, or a serious alarm;

[0110] If it is a critical alarm or a serious alarm, the device information of the opposite substation corresponding to the equipment currently requiring monitoring can be supplemented, and the intensity and cycle of the inspection can be increased to formulate an inspection plan;

[0111] The inspection plan is sent to the substation, and the substation performs inspection operations according to the plan. The substation sends the inspection content to the operation and maintenance main station, and the operation and maintenance main station comprehensively determines whether the substation has hidden faults.

[0112] Therefore, the present invention uses a mapping table to generate patrol plans, accurately locating alarm-related devices, making patrols more targeted and improving patrol efficiency. Furthermore, differentiated measures can be taken based on the alarm level, with patrols strengthened for severe alarms and resources allocated rationally. This allows for timely handling of severe issues while avoiding overinvestment in common alarms.

[0113] Furthermore, for analog quantity over-limit alarm types, when generating inspection reports, emphasis is placed on trend analysis and threshold judgment. For example, time series data (such as the current values ​​of the past 15 days) can be collected to generate a trend curve, and the rate of change can be calculated. By comparing the rate of change with a preset threshold, progressive hidden dangers can be identified. Therefore, by collecting time series data and performing trend analysis, the embodiments of the present invention can promptly detect abnormal changes in analog quantities. Even when the analog quantity has not yet exceeded the normal range but the rate of change is large, it can also provide early warning of potential hidden dangers, allowing operation and maintenance personnel to take timely measures to avoid the occurrence or expansion of faults.

[0114] In a preferred embodiment, for the analog value exceeding the limit alarm type, the corresponding alarm information may be: the analog value of the protection device in the power system is not within the preset analog value range; wherein the protection device includes a plurality of ports, the present invention further includes:

[0115] Drawing a virtual device corresponding to the protection device, and then generating a page including the virtual device;

[0116] In the virtual device, the port corresponding to the analog quantity in the alarm information is used as the target port;

[0117] The target port is flashed on the page, and analog quantities corresponding to the ports in the virtual device are displayed on the page.

[0118] It is understandable that if an alarm of the analog quantity exceeding the limit alarm type is received, a virtual device identical to the on-site device can be drawn based on the actual on-site device. Since the plug-in of the on-site device clearly defines which analog quantities will be output at this optical port, the corresponding port can be quickly located based on the analog quantity alarm information, thereby flashing the port in the virtual device as a reminder. In addition, the analog quantity corresponding to each port in the virtual device can be displayed on the page, such as the actual value of the device during operation, the standard value, and the difference between the two. If an over-limit occurs, the present invention can also give an alarm prompt on the plug-in port of the page, and then generate an inspection plan based on the alarm level, and collect the operating value of the port over a period of time during the inspection to form a trend curve, so as to determine whether there is a hidden risk.

[0119] Therefore, in the process of generating inspection reports for analog quantity over-limit alarm types, the present invention can timely discover progressive hidden dangers of equipment through trend analysis and threshold judgment, thereby improving the reliability of equipment and the safety of the power system.

[0120] In a preferred embodiment, Figure 3 The following is a schematic diagram of the analog alarm process. After receiving the analog alarm, the operation and maintenance master station can first locate the optical port of the plug-in and issue an alarm prompt. The value of the point where the alarm is generated is periodically collected, and a trend curve is formed based on the collected data to show the change of the analog value over time.

[0121] Then, the mapping table is searched, and a patrol plan is generated based on the content in the mapping table. The alarm level is further determined to distinguish whether it is a general alarm, a critical alarm, or a serious alarm.

[0122] If it is a critical alarm or a serious alarm, the device information of the opposite substation corresponding to the equipment currently requiring monitoring can be supplemented, and the intensity and cycle of the inspection can be increased to formulate an inspection plan;

[0123] The patrol plan is sent to the substation, and the substation performs patrol operations according to the plan.

[0124] The substation sends the inspection content to the main operation and maintenance station. The main operation and maintenance station combines the previously generated trend curve and the inspection content to conduct a comprehensive analysis to determine whether there are any hidden faults in the substation equipment.

[0125] Therefore, the embodiment of the present invention can issue an alarm prompt by locating the optical port of the plug-in, and can quickly and accurately determine the source location of the analog alarm, making it convenient for operation and maintenance personnel to directly lock the port of the problem device and improve the efficiency of fault finding.

[0126] Moreover, the alarm point values ​​can be collected periodically and trend curves can be generated, and the analog quantity changes can be presented as visual curves to intuitively reflect the dynamic changes in the equipment operating parameters, helping operation and maintenance personnel to quickly grasp the trend of equipment status changes and identify abnormal fluctuations.

[0127] like Figure 4 As shown, based on the above-mentioned various embodiments of the patrol method based on alarm information, the present invention provides corresponding device embodiments;

[0128] An embodiment of the present invention provides a patrol device based on alarm information, comprising: an alarm data acquisition module, a patrol plan generation module, and a patrol execution module;

[0130] The patrol plan generating module is configured to use the initial patrol plan as a target patrol plan for monitoring the operating status of the device when determining that the alarm level is a general alarm;

[0131] When the alarm level is determined to be a critical alarm or a severe alarm, a target patrol number is generated based on a preset number multiple and the initial patrol number; a device connected to the first device is used as a second device whose operating status needs to be monitored; and a target patrol plan is generated based on the target patrol number, each first device, and each second device; wherein the target patrol number is greater than the initial patrol number;
