Study And Application Of Fault Information Networking Technology In Grid

The information system of relay protection and fault record is the best way to analyse power system fault and relay protection information. With the development of the power system, the requirement for information system of relay protection and fault record is stricter. This paper introduces the primal experience obtained from implementing the information system of relay protection and fault in Electric Power Company. The three-level framework of main station, secondary station and substation is introduced, and it becoming more and more useful for analyzing the reason of the fault.
