Research On Application Of 220kV Intelligent Substation Technology In Regional Power Network

How to protect the energy security and climate change is a major issue faced by all countries in the world.With the development of the times and the development of network technology,the developed countries have made a series of research on the intelligent substation and have made some progress and achievements.Based on this,this paper introduces the concept of smart grid in detail,and studies the selection of primary equipment.This paper expounds the automation of the intelligent substation and the design of the two system,and studies the key system with the standard system.Then combined with the specific situation of Jiangsu Jintan intelligent substation,equipment selection and line connection,and the problems encountered in the actual work are summarized,and proposed solutions.Through the above research,the design scheme of the intelligent substation is further determined to achieve satisfactory results.The main research contents of this paper include: the first chapter introduces the development status of intelligent substation at home and abroad and the research background,and introduces the principle of intelligent substation;the second chapter expounds the connotation and features of intelligent substation,the main components are introduced in detail;the third chapter,studies the composition and characteristics of a smart substation the equipment,and puts forward a selection scheme of equipment;the fourth chapter describes the intelligent substation automation and auxiliary two system characteristics and development,and summed up the different schemes;the fifth chapter takes Jiangsu Jintan substation as an example,introduces the design scheme and equipment selection,and solve the problems in running;In the sixth chapter,the author summarizes the technology of intelligent substation,points out the existing problems and puts forward the prospect of the future.
