The Construction And Operation Study Of Daozhuang 220kV Intelligent Substation

The substation plays an important role in the transmission of power in the grid.With the progress of intelligent technology,smart substation will become the direction of substation construction in the future.The importance of intelligent substation is increasing,the use of advanced and reliable and intelligent electronic equipment,the use of network communication technology,information collection,transmission and application will become imperative.At the same time,with the rapid development of Internet technology and intelligent automation technology,the construction of Smart Substation will focus on the effective combination of new technology and existing substation technology.This paper analyzes the construction necessity of the 220kV Daozhuang intelligent substation based on the serious situation of the Guangrao power grid which has the T-type wiring and string supply problem.Then,considering the difference between the intelligent substation and the traditional substation in the process of construction and operation,this paper analyzes the basic theories and principles of intelligent substation construction with reference to the construction of some intelligent substations in China.It summarizes the characteristics of intelligent substation including structural features,operation and maintenance characteristics.Also,this paper provides the detailed design prinicples of Daozhuang intelligent substation and analyzes the structure and operation mode of Guangrao power grid after the operation of 220kV Daozhuang intelligent substation.Finally,in view of the frequent occurrence of accidents in intelligent substation,this paper puts forward the operation and maintenance management plan for the 220kV intelligent substation.
