In order to improve the level of intelligent substation relay protection technology,this paper takes a 110 kV intelligent substation of a petroleum enterprise as an example.Starting from the requirements of substation relay protection,a complete set of relay protection system is built through reasonable configuration of hardware system and software system.It integrates S3C2440A chip,Roche coil current transformer,Ethernet,RS-485 bus,LwIP protocol and other technologies.After testing,the performance and function of the relay protection system meet the requirements of actual and national standards.
