Research Of Medium Voltage Distribution Network Automation System

Urban distribution network is generally in the city center and the residents of agglomerations, where requires a large number of high quality power. The level of the power supply reliability and quality of power quality directly related to the satisfaction of users, the traditional technology and management mode is unable to adapt to the new situation by achieving these goals in high standards, so we must use modern means to improve the level of the power supply automation in distribution network, realizing the distribution network's real-time monitoring and automatic controlling, improving the speed of the accident reflects, that is, to construct the distribution automation system.This paper studies the key techniques and core link of constructing the distribution automation system, main arounding with the master station system station system, feeder automation mode and distribution network communication system three aspects. Finally, according to Maanshan city's present situation and the demand, The paper putted forward the construction plan of medium voltage distribution network automation system for the city, researched and analysised the construction of master station system? the renovation of termina? communication system and information interaction, and pointed out the potential problems and technology risk. The contents of this paper can provide the reference for the construction of medium voltage distribution network automation system in large and medium-sized city.
