The Design Of The Yungu 220 KV Intelligent Substation

Intelligent substation is an important node of strong smart grid, which is the source of smart grid data collection and the command execution units. SGC 09 in the design of intelligent substation construction pilot work, and very significant accomplishment. In 2012, this paper puts forward the design and construction \"covers an area of less, save cost, high efficiency\" of a new generation of intelligent substation, structure layout is reasonable, the system is highly integrated, advanced technology and equipment, energy conservation, environmental protection, economy to support regulation. Through the substation set optimization technology concept, improve the structure layout is reasonable; Focus on improve the application level of substation advanced features.This article according to the company’s latest design intelligent substation construction requirements, use advanced technology and equipment, fully considering the reliability of equipment operation, advanced and current power grid operation experience to choose the type of equipment; According to the local natural environment and the design requirement of intelligent station to effective and reasonable layout, reasonable arrangement of an equipment layout structure, try to save power and covers an area of device and, in turn, reduce construction cost. In accordance with the requirements for the design of intelligent station, and according to the existing substation intelligent solution pilot experience, choose the second intelligent equipment, realize the integration of rational arrangement of the monitoring system, the related secondary equipment to devolve to a interval, reduce the secondary equipment group of ark, reduce dosage of secondary cable at the same time, further reduce the building area. At the same time to save investment and protect the environment.This design in cold area engineering design scheme, although according to the local environment, but the plan is still has certain applicability, for covering an area of less, serious air pollution and other regions, also to have certain reference value for the design of a new generation of intelligent station construction to provide the reference.
