Research On Intelligent Transform Method Of Substation Adapted To Ubiquitous Power Internet Of Things

Substation is one of the core energy conversion platforms.As industrial tech-nology rapidly developing,new technologies such as artificial intelligence and Internet+ have been applied successively,with achievements deeply integrating in various fields.New concepts such as Industry 4.0 have been put into practice one after another.The revolutionary change of industrial production mode has promoted the innovation of society in an all-round way.The upgrading of intelligent substation technology can be integrated with a large number of innovative technical elements.With the development of unattended mode,efficiency has been improved,but relatively lagging behind compared with the rapid development of technology.Compared with conventional substations,intelligent substations adopt merging units,intelligent terminals,integrated monitoring and control equipment;the traditional secondary wiring is cancelled,and the logical relationship and data flow between devices are determined by SCD files,so the degree of intelligence is improved.However,the daily work still follows the tradition of 20 years ago,the advantages of the new technology have not been fully utilized.With the remarkable increase of substations,the workload of substation is becoming heavier and heavier,and the problem of personnel structure has become increasingly prominent.This paper puts forward an intelligent transformation scheme for substations that suits Ubiquitous Internet of Things(UIoT),and realizes the overall perception of primary equipment and secondary system of substations,and solves the problem of low manual efficiency.The scheme is divided into three parts:the intelligent transformation of primary equipment;the intelligent transformation of secondary system;substation switching operation,the study of "one-key sequential control"switching mode,to solve the current switching process of cumbersome operation,improve switching efficiency.Through the above three aspects of research,this paper ultimately realize the overall perception and intelligent early warning of all substation equipment,solve the contradiction between the insufficient number of personnel and the increasingly heavy workload of operation and inspection,and realize the ubiquitous interconnection of substations.
