Analysis of 500kV Intelligent Substation Relay Protection Configuration Design Scheme
The intelligent substation takes DL/T860(IEC61850)as the core,and uses optical fiber transmission technology to effectively overcome the shortcomings of traditional substations,and has advanced application characteristics such as local information collection,information sharing networking,information interaction integration,and information application intelligence.In this paper,the structure and characteristics of the secondary system of the 500kV intelligent substation are described in detail,and the targeted design scheme of AC current,voltage data sampling,and GOOSE networking mode at the process layer is proposed.
