Transformer Stations Integrated Automation System Communications Network Technology Research And Applications

With the rapid development of the national economy and the electric power industry, electric power system automation and informationization level demands are increasingly high. Transformer stations of the grid system as an important basic element, its level of automation directly affect the grid security and stability, thus transformer stations Integrated System has been rapid since the development and promotion of the application as an important measure of the power level on the basis of enterprise automation. And secure and reliable network communications technology is the realization of the fundamental guarantee for transformer stations integrated automation system. Therefore, the author of the substation automation system integrated communications network technology conducted explored.First the papers reviewed substation automation integrated development history, analysis of transformer stations integrated automated content, design and technology trends, transformer stations integrated automation system architecture, reality mode of the remote communication and comprehensive analysis of the transformer station automation systems commonly used data communications networks : the bus and Ethernet technology, and the comparison will be drawn using Ethernet technology integrated substation automation system communications methods optimal choice conclusions. Ethernet-based integrated automation system software and hardware in-depth research programmes and made rapid Ethernet Ethernet to the upgrading programmes.Papers study the series of integrated automation system's communications hardware and software modules designed finally, and in the Statute of the system architecture analysis IEC60870-5-103 basis in the statute for 103 transformer stations integrated automation system had a thorough discussion of the specific application.
