Design And Implementation Of Substation Monitoring System

Substation is an important part of power transmission and distribution system and plays an important role in the operation of power system. During the actual operation of the process, there are a variety of security needs, such as: monitoring of the working environment, monitoring of the operating room, and monitoring of access personnel, etc; there may also encounter a variety of problems, such as: abnormal working status of equipment, peripheral security of substation, etc. The traditional method of substation management is to use artificial method to manage the substation. With the development of the substation and the increasing complexity of operation environment, the traditional manual management mode has been unable to meet the requirements of the daily management of the substation. On the basis of the rapid development of computer and network technology, the scheme of substation automation management is put forward. Substation automation management, combined with a variety of hardware devices,is making use of computer communication technology to monitor the situation of the substation in real-time.On the basis of the existing substation automation management, this paper designs and implements the substation monitoring system based on the special situation of the 220 KV Tu You substation, which includes the following aspects of the content:(1)Video monitoring function. Video monitoring function is the basis of the whole monitoring system, and other functions are more or less dependent on video monitoring function. The contents of the video monitoring are: working area, access to the level, the surrounding environment, running equipment, etc. In this paper, a monitoring scheme based on the combination of the position and function of the equipment is designed for different monitoring content. According to different needs, duty personnel can choose to view the corresponding monitoring screen, to achieve the function of rapid positioning and fixed point view of the camera.(2)Temperature detection function of equipment joint. The temperature detection of equipment joint is achieved through the video monitoring function. The temperature of equipment is detected by the infrared imaging instrument. The temperature information is transmitted to the monitoring center through the computer. Compared with the traditional method of hand-held infrared detector for temperature detection, this method greatly improves the work efficiency. Temperature abnormal alarm function also makes the abnormal situation of equipment get treatment in the shortest time.(3)Fire alarm and anti-theft function. Fire prevention is based on smoke detectors to achieve. The pulse power grid and the infrared probe are installed in the peripheral of the substation to realize the anti-theft function. And set up the obvious sign. At the same time cameras will be installed surrounding the substation, and equipped with remote propaganda function, in order to maximize the extent of reducing accidental injury to people and livestock.
