The network system of transmitting relay protection and fault information

The transmitting relay protection and fault information system is a distributed system. It is a complete solution for analyzing and processing the relay protection and fault information of power system. The architecture and functions of the primary station and secondary station of the relay protection and fault information system are simply introduced in this paper. The shortages of the transmission system of relay protection information that is currently used are analyzed as well. Through the analyzing of the information transmission system and info-flow direction,the concept of single secondary station and multiple primary stations is given. Combined with the architecture of data transmission network of power system and the idea which is based on optical fiber,SDH and IP technology,a configuration of transmission network of relay protection information is put forward. The characteristics of this new scheme are analyzed.
