Research And Analysis Of Intelligent Station Of Shijiazhuang Lianjiazhuang 110kV Converting Station

This article mainly through the research on the intelligent construction process and the main electrical technology of the 110 kV Lian Jiazhuang substation in Shijiazhuang City,and analyzes how the intelligent construction of the 110 kV Lian Jiazhuang substation of Shijiazhuang city through the application of intelligent one equipment,intelligent unit components and other key intelligent technologies to make scientific research and further improve The intellectualization level of primary equipment is optimized,and the structure design of station area control system is optimized.Through in-depth investigation and investigation of the current situation of the Xingtang power grid,the short circuit capacity and load demand change of the power grid in this area are analyzed.The main transformer,circuit breaker,isolation switch and current transformer,as well as main transformer protection,line protection and automatic assembly,are studied.The main equipment selection,technical requirements and construction plan of the two substations are set up.The main technical requirements and construction targets of the intelligent construction of Lian Jiazhuang 110 kV substation are put forward,and the final intelligent construction plan of the new technology application is explored by the planning of the local local conditions,the rational layout and construction of the 110 kV substation in Lian Jiazhuang city.Through the analysis of the current situation of power grid equipment in the areas such as single Yang Gang and Bei Village,this paper studies the construction scheme of the intelligent substation of Lian Jiazhuang,and puts forward the new technologies such as combining unit,intelligent terminal and main transformer on-line monitoring system to improve the intelligentized level of the Tang power grid and enhance the self-healing power of the power grid in this area.The design of prefabricated cabin can reduce the difficulty of construction,shorten the construction time,reduce the occupation of land resources,achieve the requirements of the construction of compact intelligent substation,and form a new set of new mode of substation construction.
