Study On The 110kV Substation Automation Of Dongguan Grid

Along with the rapid economic development in DONGGUAN, Power supply is becoming more and more nervous. Because of 110kV SHAXI substation was Running long time, These substation equipment aging of the transformer substation constitutes a great threat safe operation, Every year need pumped funds, manpower and material resources for maintenance and repair, But the effect is not ideal, Every year in transforming, every year there are new problems emerge, As to conduct a thorough transformation, built can realize the substation integrated automation.This thesis combines a 110kV substation rebuilding practice, Integrated substation automation should have the technical conditions, are presented for determining the old station integrated automation reconstruction of the basic principles, the main idea and technical function requirement are discussed, so as to explore the reform feasible scheme. And eventually reach by far concentrated surveillance, control of substation integrated automation system, not only improves the labor productivity and reduced human error operating possible.This article is divided into six chapters:Chapter 1 is the introduction of this article, the background of the topic is introduced, summarizes the integrated automation of substation and its technical development directions, then the contents of this article is also introduced.In chapter 2, the basic characteristic of the integrated automation of substation is summarized, and designs the contents, main function, information and constructional form for the integrated automation system of Shaxi substation.The chapter 3 to chapter 5 respectively designs the micro-computerized relay sub-system, monitoring sub-system, voltage and reactive power controlled sub-system, back up power auto-launch sub-system ,data correspondence system and computerized anti-misoperation system for the integrated automation of Shaxi substation.Chapter 6 studies the design and construction scheme of the integrated automation of Shaxi substation, and introduces the construction result of the project, and point out its engineering value in the integrated automation alteration of substation.
