Design And Research Of 110kV Intelligent Substation

China’s economy is in the stage of rapid development,and the consequent surge of electricity consumption has a huge impact on the traditional power grid,and smart power grid comes into being at this time.As an important link in the traditional power grid,smart substation also plays an important role in the smart power grid.Its main role is to change the voltage,and also to take into account the important power facilities of distribution,control and voltage regulation.Therefore,it is very important to design an intelligent substation that can run reliably for a long time.This paper firstly introduces the research progress of intelligent power station,and then puts forward the design demand of 110 k V intelligent substation to be designed in this paper.Secondly,the structure of intelligent substation is introduced,and the differences between intelligent substation and traditional substation are compared.Three types of main equipment of 110 k V intelligent substation designed in this paper are introduced again.The intelligent mode of primary equipment is mainly studied,and the selection mode of primary equipment of intelligent substation designed in this paper is given.Research is mainly focused on the 110 k V on-line monitoring system for intelligent substation,introduces the composition of the on-line monitoring of each part of the total station system,for each system are analyzed in detail the pros and cons of various solutions,this article from the perspective of operation reliability and the overall economy to choose the most suitable online monitoring system configuration scheme,this paper studies 110 k V smart substation are introduced the choice of electronic transformer,first introduces the development of the electronic instrument transformer,and through comparing the form item by item in detail the advantages and disadvantages of all kinds of transformer,from the Angle of operation reliability and the overall economy still choose appropriate electronic transformer,specific 110 k V is presented Selection of transformer for110 k V intelligent substationIn detail the whole 110 k V the design scheme of each part of the smart substation,including the equipment type selection of equipment parameters and substation construction scheme,the design adopts the concept of whole life cycle management,focuses on the reliability of intelligent substation,at the same time,total station communications are based on IEC61850 standard specifications,greatly improving the transmission speed and transmission levelIn the end,this paper summarizes the deficiencies of 4 points in the design of smart substation,forecasts the development trend of smart substation in the future,and puts forward the 5 points trend of future development.
