Abstract

Currently, the new substation automation uses the international standard IEC 61850 communication protocol. KEPCO is also constructing a new substation based on IEC 61850 from 2013 through the pilot application and research and development starting from 2007. However, there are few cases where existing substations(Transformer, T/L GIS, D/L GIS, etc.) have been used, and RTU based substations operating systems have been changed to SA substations based on IEC 61850. Therefore, the introduction of IEC 61850 in existing substation facilities has the advantage of enhancing the substantiality of the substation by reusing existing facilities, improving the interoperability with the latest substations introduced, and converting existing substations into systems suitable for unmanned operation. In this paper, we introduce a case of changing the existing RTU based substation operation system to digital substation using IEC 61850 field information processor, Ethernet switch and SA operation system. Also, IEC 61850 client authentication program and Wireshark, which is a packet analysis tool, verify IEC 61850 conformance and its feasibility.

현재 변전소 자동화를 위해서는 국제 표준인 IEC 61850 통신규약이 사용되어지고 있고, 국내에서도 2007년도부터 시험 적용과 연구개발을 통해 2013년부터 신규 건설되는 변전소는 IEC 61850 기반의 디지털변전소로 준공되어 지고 있다. 하지만 기존 변전 설비들(변압기, T/L GIS, D/L GIS 등)은 그대로 사용하면서 기존 RTU 기반의 변전소 운영 시스템을 IEC 61850 기반의 SA 변전소 운영시스템으로 전환한 사례는 거의 없다. 따라서 기존 변전설비의 IEC 61850 도입은 기존 설비 재사용으로 변전소의 지속가능성을 증대시키고 또한 최신 도입되는 타 변전소와의 상호운영성을 개선하고 기존 변전소를 무인화 운전에 적합한 시스템으로 전환할 수 있는 이점이 있다. 본 논문에서는 기존의 RTU 기반 변전소 운영시스템을 IEC 61850 기반의 현장정보처리반, 이더넷 스위치반, SA 운영시스템을 이용하여 디지털 변전소화한 사례를 소개하고, 패킷 분석 툴인 IEC 61850 클라이언트 인증 프로그램과 Wireshark를 사용하여 IEC 61850 적합성 및 그 타당성을 실증을 통하여 검증하였다.
