| Abstract: |
| A relay protection and fault information management system is provided to improve the fault analysis and the device management,which is composed of a master system,subsidiary station systems and substation systems,connecting with the power dispatch data network.Its overall framework,function subdivisions,the master station and the substation configuration are presented.Connection schemes of the protection and fault recorder with the substation under different conditions,the interconnection of the substation and the SCADA system,and the system security and reliability schemes are emphasized.Based on the comparison,the scheme of indirect connection of protections with the subsystem and independent LAN of the substation is recommended. |
| Key words: relay protection,fault recording,information management system |
