Research on Key Technologies of Video Intelligent Identification and Security Management and Control System in Substation

With the development of substation automation technology, unmanned substation operation mode has become a trend, at present, many substations to achieve the "remote viewing" function, will be the scene of the substation, the equipment state to video image transmission to the remote control center (set control station). And scheduling center (set control station) on live video equipment to control and adjust, however traditional remote vision system can improve the automation level of substation, but due to technical, management and other aspects of the reasons, it is difficult to achieve substation real unattended, not completely reached synergism of depletion of numbers and intrinsically safe. Substation operation, management personnel not only need to see every corner of the substation in the remote monitoring center, but also the abnormal phenomenon of the environment in time, and remote control to dispose of. With the rapid development of science and technology and the revolutionary breakthrough of video processing technology, this paper introduces the key technology of "intelligent video image analysis technology", and the new generation of "large video management and control software platform", which is based on the new design concept. The system can provide remote vision system in the field of substation, the running state of the equipment, the image switching operation process state image, state instrument image, and on-site maintenance work on-site real-time image at the same time; in contact with the original substation communication equipment and electrical equipment case, digital remote video image acquisition equipment, and carries on the analysis the automatic processing and recognition, equipment and staff positions, knife gate opening and closing state change of power system, the instrument display read the contents of monitoring, and issued a warning signal according to the set requirements, provide a new method for automatic detection of fault diagnosis, unattended substation monitoring and control, through accurate fault, timely early warning information accident analysis, auxiliary diagnosis, to improve the reliability of grid, reducing safety accidents, is of great significance to reduce monitoring cost of operation and maintenance. This paper presents the results of project development for power dispatch, high voltage operation (interval protection), high pressure area equipment maintenance, provide on-site abnormal image automatic alarm display, and the scene of automatic alarm and alarm, so as to achieve the "safe operation of the substation" visual, from the technical means to further the substation safe production, in particular, to effectively prevent personal injury, provide a strong guarantee.
