Description

Technical Field

[0001] The present invention relates to a method and device for dynamically monitoring anomalies in a distribution substation, belonging to the safety supervision technology of distribution substations. Background Art

[0002] With the rapid development of the economy and the power industry, the number of power-using facilities and distribution substations that are closely related to people's work and life is increasing, bringing great convenience to people's electricity use. In the existing safety supervision system of distribution substations, the supervision of distribution equipment usually relies on manual inspections or traditional sensor detections. Manual inspections require a large amount of manpower and time, and there are problems such as incomplete inspections and untimely monitoring; while traditional sensor detections are limited by their fixed positions and functions, and cannot achieve comprehensive dynamic monitoring of equipment and personnel.

[0003] At the same time, the data collected by front-end devices such as sensors are usually displayed at the back-end in the form of numerical values or curves. Due to the large number of sensing devices, it is difficult for back-end monitoring personnel to quickly understand the overall situation, which is not conducive to the handling of emergency situations and the understanding of the overall situation. Summary of the Invention

[0004] Object of the Invention: In order to overcome the deficiencies in the prior art, the present invention provides a method and device for dynamically monitoring anomalies in a distribution substation, which can comprehensively and dynamically monitor the distribution substation based on thermal imaging maps, and intuitively reflect the overall operating state of the distribution substation, facilitating supervisors to directly and quickly understand the operating conditions of the distribution substation in an all-round way.

[0005] Technical Solution: To achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] Under normal operating conditions, the temperature distribution in the distribution substation is a relatively stable state, and the positions of heat sources are fixed; during the operation of the distribution substation, the vast majority of faults can be reflected in the temperature changes of distribution equipment. Due to the heat conduction effect of air, it will further affect the operation of other surrounding distribution equipment; if the distribution equipment operates over-temperature, it will reduce the performance and service life of the distribution equipment, cause faults, and further affect the normal operation of the power grid, and even cause electrical fires, resulting in huge economic losses. Therefore, by observing the change trend of the temperature distribution in the distribution substation, the position of the abnormal point and its impact on the surrounding distribution equipment can be intuitively understood, thereby ensuring the stable operation of the distribution substation.

[0007] A method for dynamically monitoring anomalies in a distribution substation, which monitors the anomalies of power distribution equipment in the distribution substation, displays the temperature distribution of the distribution substation through a global thermal radiation map, and marks the data collected by the corresponding position sensors and the alarm information at the alarm position on the global thermal radiation map; First, collect the grayscale image of the top view of the distribution substation as the background image, and mark the positions of the specified power distribution equipment in the background image; Then, use the distributed infrared thermal imaging cameras in the distribution substation to collect the thermal infrared images of the distribution substation at different positions and perspectives in real time; Next, based on all the thermal infrared images of the distribution substation at a certain moment, construct the top view thermal radiation image of the distribution substation at this moment on the background image; Next, mark the data collected by the specified sensors at the corresponding positions on the top view thermal radiation map to form a global thermal radiation map; If there is alarm information at this moment, mark the alarm information at the position pointed to by the alarm information to obtain a global thermal radiation map marked with alarm information. By directly observing the global thermal radiation map, the overall operation status of all equipment can be intuitively viewed, and the abnormal points can be quickly identified based on experience; By performing time series analysis on the global thermal radiation map, the change trend of the heat source can be observed, and the impact of the abnormal points on the entire distribution substation can be analyzed. Generally speaking, when the distribution substation operates stably, the change of the global thermal radiation map is very limited; When there is a failure of power distribution equipment in the distribution substation, the relevant power distribution equipment will undergo thermal changes, which will in turn affect the change of the global thermal radiation map, and alarms can be issued according to the change trend.

[0008] In this case, the specified sensors are mainly the real-time information of some important power distribution equipment or key data. For example, the terminal voltage and current of the transformer, etc. In terms of temperature, there are mainly the temperature of the high-voltage switchgear, the temperature of the transformer, the temperature of the low-voltage switchgear, the temperature of the busbar trunking, the temperature of the distribution box, etc. Marking the data collected by the specified sensors can, on the one hand, correct the global thermal radiation map, and on the other hand, indicate the accurate temperature value to facilitate the staff to understand the overall operation status of the distribution substation in a timely manner. When displaying on the display terminal, the global thermal radiation map and the most important sensor values can be directly displayed. For other sensor values, punctuation marks can be used in the global thermal radiation map. When the point is selected to the punctuation mark position, relevant information can be displayed through a pop-up window or other means.

[0009] In this case, due to the large number of equipment and wide field of view in the distribution substation, the distributed infrared thermal imaging cameras are used to collect the thermal infrared images of the distribution substation at different positions and perspectives in real time, and the global thermal radiation map is constructed by splicing all the thermal infrared images of the distribution substation at the same moment. The splicing method used is the existing relatively mature panoramic image splicing method to form the top view thermal radiation image inside the distribution substation.

[0010] Specifically, the top view of the substation is the top view photo after grayscale processing of the RGB color photo of the substation top view, or the top view design drawing of the substation. The positions of specified power distribution equipment are marked in the top view photo or top view design drawing. The use of the background image is to be able to display the main power distribution equipment inside the substation simultaneously when showing the global heat radiation map, facilitating the understanding of the direct relationship between the power distribution equipment and the temperature distribution. It is recommended to select the top view design drawing of the substation as the background, which is simple and accurate.

[0011] Specifically, it also includes the dynamic monitoring of the personnel entering and leaving the substation. First, the mobile client sends the information of the task to be executed to the platform supervision system. The information of the task to be executed includes the task executor ID and the substation ID. Then, the platform supervision system first confirms the distance between the position of the mobile client and the geographical position of the substation ID, then performs face recognition on the face image, and finally forms the instruction to open the substation door through manual confirmation. It is confirmed that the personnel entering the substation are consistent with the task executor ID by tracking the target in the personnel movement video stream. This design restricts that at the platform supervision system end, there is someone online to supervise when entering the substation. Furthermore, it can realize that when the on-site staff is operating, there are personnel at the platform supervision system end for remote safety supervision, meeting the management requirement that single-person execution is not allowed during the operation of the power system through system design.

[0012] Specifically, it also includes dynamic monitoring of abnormal actions of power distribution equipment. First, the mobile client sends task information to be executed to the platform supervision system. The task information to be executed includes the ID of the substation and the task content. Then, the platform supervision system generates a human-machine interaction task list and an automatic execution task list based on the task content. Next, the human-machine interaction task supervision unit forms an electronic work order containing the human-machine interaction task list according to the human-machine interaction task list issued by the task review unit, and updates the completion status of the electronic work order through human-machine interaction. At the same time, the automatic execution task supervision unit forms an electronic work order containing the automatic execution task list according to the automatic execution task list issued by the task review unit, automatically sends a task instruction to the specified power distribution equipment according to the set conditions, collects the task execution status feedback by the specified power distribution equipment, and automatically updates the completion status of the electronic work order. Then, the alarm unit issues a numerical anomaly alarm for the information collected by the sensor, issues an action anomaly alarm for the power distribution equipment other than the human-machine interaction task list and the automatic execution task list, issues an attribute anomaly alarm for the electronic work order, and locates the position of the power distribution equipment pointed to by the alarm information. In the design of this solution, after the mobile client sends the task to the platform supervision system, the platform supervision system will disassemble the task into two task lists for manual operation and system automatic operation. The tasks in the human-machine interaction task list need to be operated item by item manually, and the tasks in the automatic execution task list are automatically executed by the system according to the conditions. For the tasks in the human-machine interaction task list, personnel need to confirm through human-machine interaction to ensure that the tasks are carried out in an orderly manner. This design can further design the personnel at the platform supervision system end to verify and confirm to achieve the purpose of review and inspection.
