VE3007 KJ2005X1-BA1 12P4375X012 distribution network automation construction, in China, despite the late start, but also has been carried out for nearly 20 years of research and practice, to achieve initial results. But most of the research and practice results are in the high-voltage distribution network (35 k V or more) level, but in the medium and low-voltage distribution network (distribution room level) automation issues, or a blank, neither the overall planning, nor a unified technical principles. Not only that, the current vertical monitoring is generally limited to the substation before the line, from the substation feeder to the end user belongs to the scope of power management monitoring, in addition to a few large users of load control, there is no other monitoring means.

VE3007 KJ2005X1-BA1 12P4375X012 automation of medium- and low-voltage distribution networks (mainly switching stations, switching rooms, and switching houses) and the automation of transformer substations have certain similarities. Therefore, it is of great significance to analyze the realization method of substation automation to correctly determine the automation scheme of medium and low voltage distribution network.

VE3007 KJ2005X1-BA1 12P4375X012 substation automation system consists of five parts: the main station, remote terminal units (re mote terminal units (RTUs)), line sensors, remote control SF6 or vacuum switches, and communication cables. Among them, RTU devices are located at the substation site, which can automatically collect various switch status quantities (telecommunication) and analog quantities (telemetry) and transfer them to the main station system of the monitoring center through a special channel; some RTUs can also perform specific remote control operations according to the intention and instructions of the monitoring personnel and return the results of the operations to the main station system of the monitoring center.
