IEC 61850 is the worldwide protocol for the substation automation system. IEC 61850 transports the information which consists of different formats such as GOOSE(Generic Object Oriented Substation Event), MMS(Manufacturing Message Specification), SV(Sampled Values) and so on. For real time data transmission, GOOSE can be used. The remote-bus current data which were collected in a local-bus current differential IED can be transmitted to a distance IED at the same location by using GOOSE messages. The distance IED can eliminate the reactance effect by using the transmitted remote-bus current data. This method can improve the performance of the fault location.

In order to prevent loss of communication packets and drop of transmission speed owing to the network fault occurrence, it should be considered network redundancy. That is why a messages of IED GOOSE is the critical signal in charge of protection and control of the substation. So most of users implement the substation automation system with Hybrid network topology ant IED supporting double ethernet ports. Because IEC 61850 GOOSE conformance test is limited in the functional test, this paper suggests how to test the performance of IED GOOSE transmission considering Network redundancy, and describes the analysis of an example test on real IEDs and how to impact the IED GOOSE performance to the substation automation system.

IEC 61850은 변전소 자동화 시스템에 관한 국제표준문서이다. IEC 61850의 특징의 중의 하나로서 GOOSE가 있다. GOOSE는 변전소기기 간에 빠르고 신뢰성을 보장하여 기기들 간의 정보교환을 위한 IEC 61850 통신 서비스이다. IED는 GOOSE 메시지를 통해 트립 신호와 같은 중요한 정보를 전송한다. 현재 몇몇의 IEC 651850 기반의 기기들이 개발되었고, 한국에서는 IEC 61850 기반의 IED를 개발하고 있다. IEC 61850 표준문서에서 오류, 모호한 점 그리고 추가할 점들이 발견되고 있다. 이러한 문제들은 Technical Issues라 부른다. 이 논문은 IED 개발업자 또는 검사자에게 IEC 61850과 관련된 좀 더 나은 이해와 견해를 제공하기 위하여 GOOSE에 관한 기술적 이슈를 조사한다.
