The Research Of Fault Information Processing System For Protective Relaying

The paper comes from the actual project of establishing fault informationprocessing system in changzhi power network.Described the necessity and importantmeaning of developing the processing system of relay protection.Have analyzed thequestion existing in the relay protection management.To solve these limitations,thisthesis devotes to the implementation of fault information processing system for powergrids,the architecture of fault information processing system and the hardwarecomposing of sub-station and master-station are proposed.The IEC60870-5-103 standardis applied to the data transmission.The paper emphasizes on researching theperformances of data transmission in real-time and reliability based on TCP/IP.Atlast,the conventional and advanced applications of fault information processing systemare discussed.
