Intelligent recognition monitoring system and method for unmanned substation

Abstract

The invention discloses an intelligent recognition monitoring system and method for an unmanned substation. Based on a complete IPVS (internet protocol video monitoring system), the monitoring system comprises a front-end video acquisition layer, a video storage layer and a peripheral warning layer, the front-end video acquisition layer performs real-time video monitoring for the substation by the aid of a network camera with an intelligent recognition function and transmits monitoring data to a monitoring center through a network transmission layer, the video storage layer includes substation information on-site scatter storage and monitoring center concentrated storage, the peripheral warning layer acquires environmental information through an infrared / microwave sensor, a vibration detection device and a temperature and humidity acquisition device in real time, and the monitoring center receives abnormal information transmitted by the front-end video acquisition layer, further judges the information, sieves local alarms caused by normal operation and remotely gives an alarm when abnormity really exists. An intelligent recognition module adopts different recognition algorithms for different monitoring objects, the running state of a target device and the running environment of the substation can be rapidly analyzed, and unattended operation of the substation is truly realized.

Description

technical field [0001] The invention relates to the field of automatic monitoring of substations, in particular to an intelligent identification and monitoring system method for unmanned substations. Background technique [0002] With the advancement of the smart grid, as the information source and execution terminal of the power transmission and distribution system, the substation requires more and more information and integrated control. Therefore, the current substation urgently needs a simple and intelligent monitoring system to realize information sharing, reduce investment, improve operation and maintenance efficiency, and truly realize unattended operation of substations. [0003] Substation video monitoring system generally consists of six parts: video acquisition system, video transmission system, video storage system, video display system, perimeter defense system, and monitoring command and dispatch system. The main content that needs to be monitored during the o...

Problems solved by technology

At present, this kind of video surveillance system is widely used in power system, but this type of system has a large number of limitations:

[0005] 1. Traditional analog cameras require special laying of video cables, audio cables, and control cables. Wiring construction is time-consuming, laborious, and expensive. Traditional analog cameras are easily affected by the environment, and the resolution often cannot meet the high requirements of substations for remote viewing of equipment;

[0006] 2. The traditional system is a centralized architecture, adding cameras requires re-wiring, limited expansion, and the expansion of system monitoring points and storage capacity is relatively complicated;

[0007] 3. A large amount of irrelevant video data is recorded and stored in the video monitoring process, but important events are easily overwhelmed, making monitoring difficult and waste storage resources;

[0008] 4. The system cannot realize automatic redundancy. When the embedded network video server in the system fails, the centralized control station cannot normally monitor the operation of the substation equipment, and there are hidden dangers in safe operation when no one is on duty;

[0009] 5. Limited manageability, external server and management software are required to control multiple DVRs or monitoring points, and the PC configuration requirements of monitoring points are relatively high; limited remote monitoring capabilities, can not access any camera from any client, only through DVR accesses the camera indirectly;

[0010] 6. After the storage hard disk fails, the video file cannot be automatically repaired, and the system needs to be interrupted to replace it. The video data has potential safety hazards; the wall intrusion alarm system has a high false positive rate and poor reliability; it is not easy to maintain and the maintenance cost is relatively high

[0012] The existing "video monitoring system + manual analysis" method ensures the safe operation of unmanned substations to a certain extent, but consumes a lot of manpower and material resources, and cannot quickly analyze the operating status of the target equipment, and cannot be captured and prevented in time The danger of man-made destruction of substation equipment, which leaves hidden dangers for the safe operation of unmanned substations
