Abstract
In recent years, China's power industry has shown a rapid development trend, the network is the computer technology and communication technology are showing a sustainable development trend, substation integrated automation system into the practical period. NARI NS2000 substation integrated automation system is one of them. This paper analysis and its applications in the south of the 110kV substation.
Firstly, this thesis describes the research background, research significance, research purposes, the research status at home and abroad, systematically sorting out the basic theory of substation integrated automation, such as the definition of substation integrated automation, the main characteristics of substation integrated automation, substation integrated automation system, substation integrated automation system, the key functions of substation integrated automation. Secondly, this thesis systematically analyzes and constructs the implementation and application of NS2000 integrated automation system in 110 kV substation. Comprehensive construction of NS2000 substation integrated automation system, to explore the protection and monitoring device, the study of the collection and disposal of computer monitoring information, based on a number of aspects of the design system hardware and software system, and then based on the application of the system analysis. Finally, this paper optimizes the NS2000 integrated automation system in 110 kV substation, improve the scheduling machine, strengthen the operation of the background, improve the monitoring interface, strengthen the alarm function, improve the statistics and reporting system and optimize the SOE function.
The NS2000 Nari substation integrated automation system for research, greatly improve the quality of electric energy, ensure that it is safe and reliable power state, and ultimately improve the degree of automation of the power supply, ensure the safety of production, the extraordinary significance.
Key words: NARI NS2000 substation integrated automation system, kV, 110 South substation
