초록
전력 설비를 감시하고자 하는 SCADA 시스템 표준으로 대표적인 프로토콜이 DNP3.0과 IEC61850이다. 두 표준은 각각의 특성과 장단점을 가지고 있으며, 따라서 상당 기간 두 표준이 공존할 것으로 예상된다. 본 논문은 두 프로토콜간 변환 기능을 제공하는 게이트웨이 기능을 설계한 내용을 소개한다. 두 표준 모두 객체지향 모델링을 이용하여 유사점이 많지만, DNP3.0 객체는 객체 번호와 인덱스로 묘사되고, IEC61850 객체는 이름으로 묘사된다. 따라서 이들을 변환시켜주는 기능이 필요하다. 또한 각 표준의 통신 프리미티브를 분석하여 변환 가능한 프리미티브를 표로 정리하고, 게이트웨이 기능의 처리 절차를 제안하였다.
Abstract
The DNP3.0 and the IEC61850 are the most important standards in the SCADA systems for the power. Each standard has strength and weakness, so they will coexist for a while. This paper presents a design of the gateway function between DNP3.0 and IEC61850. Both standards use object-oriented modelling methods, so, they have some similarities. However, the DNP3.0 objects are described by object number and index, and the IEC61850 objects are described by name. So there should be mapping function between the object number and index of DNP3.0 objects and the object name of IEC61850 objects. We analyse the communication profiles of both standards, and shows the service-primitive mapping table and the procedure of the gateway function.
