Description

Technical Field

[0001] The present invention relates to the technical field of power system management and control, and in particular to a terminal security management and control method based on a power monitoring system. Background Art

[0002] The power monitoring system is a system that monitors the operation process of the power system. It is mainly used to monitor and control the key equipment and parameters in the process of power production, transmission and distribution. When monitoring, it mainly monitors the terminals connected to it. The terminals connected to the power monitoring system include remote terminal units, smart meters, sensors, actuators, PLCs and communication equipment. By monitoring the terminals, the operating status of the terminals can be obtained. When the terminals are abnormal, they can be repaired quickly and in time. During the operation of the power system, due to external factors or human factors, large-scale failures will occur, resulting in failures of terminals in a certain area. When repairing the terminals, they are often repaired in sequence based on manual experience, and the repair process does not take into account the replacement of terminal spare parts. The spare parts inventory of some terminals cannot meet the maintenance status of the terminals, and they need to be purchased in advance. However, due to the lack of advance repair priority for these terminals, it is not until the final repair that it is discovered that spare parts need to be purchased. The impact of the faulty terminals in the process of waiting for repair and spare parts procurement is likely to gradually expand over time, and eventually affect the entire power system. Summary of the invention

[0003] In view of this, the present invention proposes a terminal security management and control method based on an electric power monitoring system, which ranks the repair priorities according to the difficulty of obtaining spare parts. Faulty terminals where spare parts are difficult to obtain can be processed first to avoid the continuous expansion of faults.

[0021] Step S232: if there is data outside the reference value range in the monitoring data, output the terminal as a suspected fault terminal;

[0022] Step S233, obtaining the time node at which the monitoring data of the suspected faulty terminal is outside the reference value, and searching whether there is a repair and maintenance task for the power monitoring system at the time node; if there is no repair and maintenance task, determining that the terminal is a terminal to be repaired.

[0023] Preferably, the specific steps of step S3 are:

[0024] Step S31: Determine the subjective maintenance strategy of the terminal to be repaired by expert evaluation;

[0025] Step S32: input the monitoring data of the terminal to be repaired into the trained deep learning network, and obtain an objective maintenance strategy through processing by the deep learning network;

[0026] Step S33: acquiring the required spare parts of the terminal to be repaired based on the subjective maintenance strategy and the objective maintenance strategy.

[0027] Preferably, the deep learning network in step S32 is trained using a training set and tested using a test set, wherein the training set and the test set include monitoring data of the faulty terminal and a corresponding repair strategy.

[0045] In order to better understand the technical content of the present invention, a specific embodiment is provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0046] See also Figures 1 to 6 The present invention provides a terminal security management and control method based on a power monitoring system, comprising the following steps:

[0047] Step S1, searching for a terminal connected to the power monitoring system and obtaining basic information of the terminal;

[0048] Step S2: obtaining monitoring data of the terminal from the power monitoring system, and determining the terminal to be repaired that needs to be repaired based on the monitoring data;

[0049] Step S3: determining a maintenance strategy for the terminal to be repaired, and obtaining the required spare parts for the terminal to be repaired from the maintenance strategy;

[0050] Step S4: Evaluate the difficulty of obtaining the required spare parts, and sort the repair priorities of the terminals to be repaired based on the difficulty of obtaining the spare parts.

[0051] The present invention provides a terminal security management and control method based on an electric power monitoring system, which is used to perform security management and control on all terminals connected to the electric power monitoring system, wherein the main mode of management and control is to prioritize the faulty terminals in the fault area when a fault occurs in the electric power system, and the priority ranking takes into account the difficulty of obtaining spare parts, and advances the priority of the faulty terminals for which spare parts are more difficult to obtain, thereby avoiding the continuous escalation and spread of faults of the faulty terminals caused by long waiting time for maintenance and waiting time for spare parts procurement, thereby ensuring that the electric power system is repaired as quickly as possible.

[0052] After finding all the terminals connected to the power monitoring system, the basic information of the terminals is obtained to determine the location and type of the terminals. At the same time, the monitoring data of the terminals by the power monitoring system will be obtained. If an abnormality occurs in the area or terminal, the monitoring data will also be abnormal. The monitoring data can reflect whether the terminal is faulty, so as to determine the terminals to be repaired. For the terminals to be repaired, a maintenance strategy can be determined according to the different faults, and the maintenance strategy will include the spare parts required to repair the terminals to be repaired. Finally, the difficulty of obtaining the required spare parts is evaluated, and then the repair priority can be sorted according to the difficulty of obtaining. Finally, the terminals to be repaired can be repaired in sequence according to the repair priority.

[0053] Preferably, the specific steps of step S1 are:

[0054] Step S11, obtaining the topological structure of the power monitoring system;

[0055] Step S12: searching all terminals connected to the power monitoring system from the topology structure;

[0056] Step S13: Obtain the device name, manufacturer, model, installation location, supplier and after-sales support of the terminal.

[0057] When it is necessary to find the terminal of the power monitoring system, it is necessary to obtain the topological structure of the power monitoring system. The terminal connected to the power monitoring system can be found from the topological structure, and then the basic information of the terminal can be obtained, where the basic information includes the device name, manufacturer, model, etc. The basic information of the terminal can be obtained to facilitate the subsequent judgment of whether there is a fault abnormality through monitoring data.

[0058] Preferably, after finding all the terminals connected to the power monitoring system, step S12 uses a network scanning tool to scan the power monitoring system, identifies all online terminals, and compares them with the terminals found through the topology structure. When there are differences in the comparison results, it is confirmed whether the terminals with differences are connected to the system, and finally all the terminals connected to the power monitoring system are determined.

[0059] In the power system, there are often some terminals connected or revoked, and some terminals are not connected to the system. Therefore, after finding the corresponding terminals through the topology structure, the power monitoring system is scanned using network scanning tools such as Nmap to obtain all terminals connected to the power monitoring system. The scanned terminals are compared with the terminals found through the topology structure. If there is a difference in the comparison results, the staff can confirm whether to connect to the system. Finally, all terminals connected to the system can be confirmed to avoid blind planning of maintenance strategies and maintenance of terminals in the future.

[0060] Preferably, the specific steps of step S2 are:

[0061] Step S21, dividing the power monitoring system into several functional areas, and determining the terminals within the functional areas;

[0062] Step S22, obtaining monitoring data of all terminals in the functional area where the abnormality occurs;

[0063] Step S23: Determine whether a terminal fails according to the monitoring data, and output the failed terminal as a terminal to be repaired that needs maintenance.

[0064] After obtaining the terminal connected to the power monitoring system, the functional areas are divided according to the areas monitored by the power monitoring system, and multiple functional areas are obtained. The power monitoring system can obtain the reported abnormal information and determine the functional area to which the abnormality belongs. Then, the monitoring data of all terminals in the functional area is obtained to avoid obtaining the monitoring data of other irrelevant functional areas, reduce the amount of data, and finally determine whether the terminal has a fault based on the monitoring data.

[0065] Preferably, the specific steps of determining whether the terminal has a fault according to the monitoring data in step S23 are:

[0066] Step S231, determining whether the monitoring data is within the reference value range during the operation of the terminal;

[0067] Step S232: if there is data outside the reference value range in the monitoring data, output the terminal as a suspected fault terminal;

[0068] Step S233, obtaining the time node at which the monitoring data of the suspected faulty terminal is outside the reference value, and searching whether there is a repair and maintenance task for the power monitoring system at the time node; if there is no repair and maintenance task, determining that the terminal is a terminal to be repaired.

[0069] When determining whether a terminal is faulty, first determine whether the monitoring data is within a baseline range. If the monitoring data is within the baseline range for a period of time before and after the fault, the terminal is determined not to have failed. If there is data outside the baseline range in the monitoring data, it can be determined that the terminal is suspected of failure. However, at this time, the terminal is not completely certain of failure, because in the daily work of the power system, the terminal will be inspected and maintained, and manual intervention will be performed on the terminal. Manual intervention may cause abnormal monitoring data. Therefore, it is necessary to determine whether there is a maintenance task for the suspected faulty terminal. After obtaining the time node of the abnormal data of the suspected faulty terminal, confirm whether there is a maintenance task at the time node. If there is no maintenance task, the terminal is determined to be a terminal to be repaired.

[0070] Preferably, the specific steps of step S3 are:

[0071] Step S31: Determine the subjective maintenance strategy of the terminal to be repaired by expert evaluation;

[0072] Step S32: input the monitoring data of the terminal to be repaired into the trained deep learning network, and obtain the objective maintenance strategy through the deep learning network, wherein the deep learning network is trained by a training set and tested by a test set, and the training set and the test set include the monitoring data of the faulty terminal and the corresponding repair strategy;

[0073] Step S33: acquiring the required spare parts of the terminal to be repaired based on the subjective maintenance strategy and the objective maintenance strategy.

[0074] After determining the terminal to be repaired, it is necessary to determine the maintenance strategy of the terminal to be repaired, where the maintenance strategy is divided into subjective maintenance strategy and objective maintenance strategy. The subjective maintenance strategy is formulated by experienced experts, while the objective maintenance strategy adopts the method of deep learning network identification. The monitoring data of the faulty terminal in the historical maintenance process and the adopted maintenance strategy are used as data sets, and are divided into training sets and test sets. The training set is used to train the deep learning network. After the training is completed, the test set is used for testing. After the test accuracy reaches the preset value, the training ends, and the monitoring data of the terminal to be repaired is transmitted to the deep learning network. After processing, the deep learning network can obtain the maintenance strategy, which is the objective maintenance strategy. After obtaining the subjective maintenance strategy and the objective maintenance strategy, the required spare parts for maintenance mentioned in the subjective maintenance strategy and the objective maintenance strategy are output as the required spare parts for the terminal to be repaired. By adopting the deep learning network, the objective maintenance strategy can be quickly obtained, avoiding problems such as policy inconsistency caused by subjective evaluation, and ensuring that the required spare parts can indeed repair the terminal to be repaired.

[0075] The basic information of the terminal includes the spare parts inventory. The specific steps of step S4 are:

[0076] Step S40: Obtain the required number of spare parts for the terminal to be repaired according to the maintenance strategy. When the required number of spare parts is greater than the spare parts inventory, execute step S41;

[0077] Step S41, finding the number of suppliers that can provide the required spare parts;

[0078] Step S42: Determine the inventory of the required spare parts of the supplier;

[0079] Step S43, determining the distance between the supplier and the terminal to be repaired;

[0080] Step S44, evaluating the difficulty of obtaining the required spare parts based on the number of suppliers, inventory, and spacing distance;

[0081] Step S45: sort the repair priorities of the terminals to be repaired according to the difficulty of acquisition.

[0082] After obtaining the required spare parts, it is necessary to evaluate the difficulty of obtaining them. Before conducting the evaluation, first determine whether the required number of spare parts can be met based on the spare parts inventory. When the spare parts inventory is greater than the required number of spare parts, it means that the current inventory can perfectly solve the repair problem of the terminal to be repaired. If the spare parts inventory is less than the required spare parts, it means that additional purchases of the required spare parts are required to achieve the repair of the terminal to be repaired. Therefore, the difficulty of obtaining the required spare parts will be evaluated at this time to avoid wasting resources by directly conducting the evaluation.

[0083] When evaluating the difficulty of obtaining the required spare parts, multiple aspects are considered, including the number of suppliers who can provide the required spare parts, the inventory of the required spare parts of each supplier, and the distance between the supplier and the terminal to be repaired. The fewer the number of suppliers, the smaller the inventory of the required spare parts, and the greater the distance between the supplier and the terminal to be repaired, the more difficult it is to obtain the required spare parts. At this time, it is necessary to increase the repair priority of the corresponding terminal to be repaired so that the staff can promptly discover the need for procurement, thereby shortening the waiting time for the terminal to be repaired. It is only necessary to wait for the time to purchase the required spare parts. At the same time, the staff can perform emergency treatment on the terminal to be repaired, such as cutting off the connection before and after the terminal to be repaired and temporarily replacing other terminals, etc., to avoid the expansion and spread of the fault and ensure the normal use of the power system.

[0084] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
