Substation Area Protection Collaborative Testing Based on IEC61850
Substation area protection application,one of the significant characteristics of the new-generation smart substation,integrates BZT devices,line protections and bus differential protections and provides redundancy for in situ protections.The highly integrated nature of substation area protection poses higher requirements for collaborative work performance between different types and manufactures of protections.This paper presents a new substation area protection method based on intelligent relay-protection collaborative testing system (IRPCTS).SCD file matches,GOOSE virtual terminal association characteristics and coordination work performance between IED devices have been verified by the simple bus protection testing based on IRPCTS platform.
