In this paper, we propose the protection coordination algorithm using communication methode based on IEC 61850. The communication protocol in power distribution management system has been issued by IEC standard, IEC61850 of them, which was made for substation automation system, has researched to apply into power distribution system, even though the standard is not a suitable for the system. In smart distribution management system' launched in 2009, the communication network based on the ethernet network for IEC 61850 has been designed to apply the self-healing concept, which is to perform the system protection through the communication between remote terminal units(RTU) according to the standard. However, it is first time to apply the scheme in the real. Thus, this paper proposed the protection algorithm and consideration for applying communication method and introduced the result of demonstration.

In order to construct the IEC 61850 based substation automation system, the IED integration engineering tool is necessary to cope with the substation automation by full digital devices in the real power system. Compared the configuration tools provided IED vendors which are able to support the operation and communication analysis among IEDs, the XML based IED integration engineering tool can build, edit and save the ICD, SCL and CID files. Particularly, the IED integration engineering tool is possible to apply the IEC 61850 based IEDs to engineering the systems and also provides the reliability and efficiency of the system to the utilities and manufacturers.

IEC 61850은 변전소자동화시스템에 대한 국제 표준이다. IEC 61850 파트 7에서는 상호운용성을 위하여 IED (Intelligent Electronic Device)에 구현해야 할 정보모델과 서비스 모델을 추상적로 정의하였다. IEC 61850 파트 8에서 정의된 SCSM (Specific communication service mapping)은 추상적인 객체와 서비스를 MMS (Manufacturing Message Specification, ISO 9506) 와 ISO/IEC 8802-3으로 매핑하는 것을 정의한다. 이 논문은 SCSM을 이용하여 어떻게 IEC 61850 기반의 IED를 구현해야 하는지 설명한다.

With the advent of the international standard IEC 61850 for communication networks and systems in substations, utilities are beginning to implement substation automation systems (SAS) that can give support to interoperability, interchangeability and self-description features. This paper describes with the SAS design accordance with this new standard. After a brief introduction of IEC 61850 SCL, this paper addresses some issues related to the specification of an IEC 61850 based SAS, and describes the Substation Configuration Language (SCL) based on Extensible Markup Language (XML). The SAS design process is explored with examples including the Intelligent Electronic Device (IED) selection, Logical Nodes (LN) allocation and the related services and the SAS communication architecture.

Substation Automation System (SAS) based on IEC 61850 is becoming more and more reality in applying power systems. As well, the development of various engineering tools and the convergence with diagnostic systems are underway. To reflect recent advancements in SAS technology, the Korea Electric Power Corporation initiated a 154kV SAS pilot project and a smart power grid business in 2010. In this paper, the authors will summarize the overview and the lessons learned in applying the IEC 61850-based 154kV Main transformer bay IED solutions to these two project.

2005년 유틸리티 산업분야 국제표준 규약으로서 IEC61850이 발표된 이후, 변전소 자동화 시스템 설계 및 구현을 위한 새로운 패러다임으로 인식되고 있다. 현재, 유럽시장을 중심으로 IEC61850 규약과 호환되는 많은 제품들이 출시되고 있고 다양한 구현사례를 통해 그 적용가능성 및 타당성이 검증되고 있다. 그러나, 변전소 자동화의 기본 통신규약으로서 IEC61850이 도입될 경우, 이미 기존에 설치되어 운용중인 수많은 전력설비 감시/제어 시스템 및 상위 제어센터와의 통신 호환성 문제가 발생되며, 향후, IEC61850 기반의 디지털변전소 확대 적용에 장애 요인으로 대두되고 있다. 본 논문에서는 이러한 문제점을 해결하기 위해 IEC61850 기반의 변전소자동화 용 게이트웨이 시스템을 설계하고 구현하였다. 제안된 시스템은 기존에 운용되고 있는 전력설비 감시/제어 시스템과의 호환성 제공은 물론, 변전소 내의 IEC61850 IED들과 상위제어센터 내의 송변전 SCADA 시스템간 통신 및 상호운영성을 제공한다. 또한, 시스템의 가용성 및 신뢰성을 보장하기 위한 이중화 메커니즘을 지원한다.

Korea Electric Power Research Institute in charge of the power IT project "Development of Prototype for Advanced Substation Automation System based on the Digital Control Technology", is performing the verification of performance of the substation automation system. In order to verify a system based BUS protection IED, the standardized document and procedures are required. But there is nothing to describe systematically how to verify IEC 61850 based IED in the system environment except an individual IED testing way and report. This paper presents the substation automation system based ways and procedures to verify the IED using UML(Unified Modelling Language).
