Technology And Application Research On Fault Automatic Isolation Of Zhuhai Distribution Network

With the rapid development of the social economic and electrical markets, usersdemands for supply reliability and power quality have become increasingly high, at the sametime, their tolerance to power failure is getting smaller and smaller. Therefore, power supplyenterprises have to improve the supply reliability of distribution network and reduce the timeof power failure in order to increase users’ satisfaction.For the purpose of realizing the above objectives, power supply enterprises muststrengthen the construction of distribution network, build and realize distribution automationas well as improve the operating management of power distribution system.As the key technology and applied function, fault automatic positioning and automaticisolation of distribution network are able to cut down the time of fault positioning andisolating and raise the supply reliability efficiently, so they are getting more and moreattention.This paper’s main tasks are as follows:First, do some researches for the present situation of Zhuhai distribution network andthe construction of distribution automatic equipment, analyze and introduce the overview,characteristics of distribution network in each districts of Zhuhai and normal running mode ofZhuhai distribution network; introduce the two-term construction of Zhuhai distributionautomation.Second, analyze and discuss the structure construction of Zhuhai distribution automaticsystem, mainly including main structure, main equipment, communicating system and keytechnology application of Zhuhai distribution automatic systemThird, analyze and discuss the pattern of realizing fault automatic positioning andautomatic isolating which fits for Zhuhai distribution network combined with the actualsituation of Zhuhai distribution network and the construction of distribution automaticequipment, and analyze and apply the technologies of fault automatic position andautomatic isolation in connection of different wiring ways of Zhuhai distribution network.Fourth, discuss the construction of hardware configuration and demands for technologyof realizing automation, fault automatic position and automatic isolation of Zhuhai distribution network.
