220 Kv Rival Intelligent Substation Design

Smart grid is put the advanced sensing measurement technology, information communication technology, technology and automatic analysis and decision control technology and electrical energy technology and power grid infrastructure high integration and the formation of new modern power grid.Intelligence is the electric power network of substation node, it connect circuits, the transmission power, for the transformation of voltage grade, collection and distribution electric energy, current control electrical energy flow, adjust voltage etc. Function. The transformer substation operation is intelligent intelligent basic part of one of the power grid. Intelligent substation advanced, reliable, integration, low carbon, environmental protection of intelligent equipment to the station the digital information and communication network and information sharing platform standard into basic requirement, and automatically complete information collection, measurement, control, protection, measurement and monitoring and other basic functions, and but according to need to support network real-time automatic control, intelligent adjustment, online analysis and decision, and the interaction between the higher functions such as substation.This article through the following several aspects of the substation of220kV NaXi intelligent design.1) system structure:the paper according to IEC61850substation building system structure. Will the intelligence in the transformer substation equipment into three layers:the substation layer, spacer layer and process. The connection between the substation all levels will be built on the basis of digital communication.220kV NaXi put forward the system structure of the intelligent station.2) to meet the requirement of intelligent, each layer secondary equipment configuration and and other layer of the interface. 3) to meet the intelligent request, to a equipment technology economy and product maturity and operation effect than the election, recommend the best equipment model.4) to meet the requirement of intelligent, intelligent station advanced application function,.
