A role of Distribution Automation System(DAS) is required to be changed from observing and control to complex and various new system including functions which monitoring, control, prediction, operation and management of EMS type according to be gradually Smart Grid of distribution operation system for development of further power system industrial. IEC(International Electrotechnical Commission) published communication standards which interface and data model of distribution operation system to IEC 61968 and of host system like EMS(Energy Management System) to IEC 61970. So far, each standards are emphasizing themselves, but if they are applied by designed integration of the standards, it could be more efficiency system. So, in this paper, integration application of IEC standards and structure of further distribution operation system to use them are proposed by gradually increasing importance of communication protocols, functions and roles in further distribution management system considering Smart Grid.

Since IT technology was combined with the power system, many systems and applications have been developed and also Integration between systems has been followed in order to meet much higher level. Futher more to reduce the cost of system integration there were needs standardized data model and interfaces among systems or applications. so IEC has reached to establish standard interfaces and data model. Most of the current distribution automation system in South Korea, each operating independently in an enclosed environment, are managed. As time goes by, however, because of resons that the system is increasingly complex by implenting new kind of power source and demand for electricity is rapidly increasing, it became difficult to predict with a independent data from one system. In this paper, In order to apply common infomation model and standard interfaces which are defined in IEC 61970/61968 to the exisiting distribution automation system in KEPCO, several software tools and applications which have been created will be introduced.

전력수요가 급증하면서 발전량 확보에 대한 요구에 따라 원자력 및 화력과 같은 기존 주요 발전설비로 인한 환경오염 문제에 대한 관심이 높아지고 있다. 일본 3.11 대지진과 후쿠시마 원전사고는 공급 위주의 전력에너지 정책 패러다임에 변화를 주었다. 원자력발전소 건설 규제 및 대책요구에 대한 여론이 높아짐에 따라 전력산업 전반적으로 수용가의 효율적인 에너지 사용을 포함하는 지능형 전력망(Smart Grid)과 수요반응(Demand Response) 기술이 화두가 되고 있다. 배전 시스템내의 어플리케이션 간의 정보 교환은 IEC TC-57 WG-14에 의해 IEC 61968 표준 규격으로 정의되고 Part 4인 "Records and Asset Management"에 기술된 규격에 대한 이해를 요구하고 한다. DMS와 GIS 시스템과 기존 연동하여 이러한 소규모의 마이크로그리드 시스템의 플랫폼으로 활용하도록 데이터교환 및 외부 GIS를 플랫폼으로 활용하는 통신 프로토콜을 소개하고자 한다.

The substation automation is a system to remote-monitor and control electric power flow. And in line with electrification of railway, an interest in electric railway substation automation is increasing. IEC standardized IEC 61850, IEC 61968 and IEC 61970 communication protocol for the telecommunication standardization of the electric power automation industry. The recent SCADA systems in managed electric railway substations are have the problem about the compatibility with the products which fit to the international standard specification afterward. In this paper, the model of electric railway substation automation based on IEC 61850 and IEC 61970 is presented. And the method supporting the compatibility between the equipment is proposed.

In the development of MDMS(Meter Data Management System) based on CIM(Common Information Model), which is international standard in information model and data exchange on power system, the two focused issues are the effective management of data collected in a shorter time period and the way to integrate services supporting legacy system to use the AMI(AMI, Advanced Metering Infrastructure) data. In this paper, we propose MDMS implementation methods and functions in AMI environment which are differ from existing AMR system environments in that the methods support bi-directional service infrastructure. The proposed MDMS in this paper has two unique features, one is the secure of interoperability by utilizing the CIM and ESB, the other is the improvement of field application by implementing system module based on components. On an implementation of smart grid, the result of proposed methods is expected to contribute to the efficient development and operation of CIM-based power system.

IEC 61970과 IEC 61968 시리즈에 의해 정의되는 CIM은 현재 EMS 내 어플리케이션의 모듈 통신성, transmission system electrical model들의 교환, DMS 구성 서비스를 위한 정보 교환에 적절하다. CIM은 Distribution operation에서 서로 다른 시스템을 가지는 기술적 해석 어플리케이션의 통합 과정을 촉진 시키는 데에 이용될 수 있지만, distribution network의 교환을 더욱 완벽하게 가능하게 하기 위한 모델 개선이 필요하다.

Distribution systems for operating the various systems should be operated organically. Distribution systems for organic operations extend the functionality of the system and system integration for the extension is doing. However, in systems integration for each unique non-standard definition of linkage and exchange systems are used. Non-standard definition of a unique linkage and exchange systems in the maintenance and expansion will result in many negative results. To solve these problems, the system and the exchange of information about the links between systems should define standards. IEC (International Electrotechnical Commission) power to solve these problems in the field of the Common Information Model (Common Information Model, CIM) standard (IEC61970, IEC61968) is defined as the transmission and distribution system integration and standardization for the exchange of information. In this paper, standardized system for building CIM-based distribution automation system should describe the process of building. In addition, the process of establishing a common information model needed (CIM) defined and associated services for a defined set of models is proposed in the standardization process.
