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.

Korea Electric Power Research Institute has carried out verification of communication conformance on IEC 61850 based IEDs related to power IT project "Development of Prototype for Advanced Substation Automation System based on the Digital Control Technology". Owing to IEC 61850 international standard and digital substation automation system, IED testing process should be changed from the conventional way to the new way described in the paper. This paper describes IED testing procedures based on substation automation system using UML.

In order to complete engineering works of the digital substation, Both Data transmission among a variety of IEDs and HMIs, and single line diagram of the substation might be done based on XML documents published in IEC 61850 international standards. This kind of XML based engineering process for the digital substation must be implemented not by manual written work but by the engineering tool using a computer. But most of the engineering tools do not support system based engineering works such as single line diagram of the substation but have only function to set IEDs as single device unit. Accordingly, this paper presents a new design method of the system based engineering description applicable to real IEC 61850 based substation through analyzing the current international standard and its sampled engineering file, and shows implementation of the engineering tool of the digital substation with the result of this study.

Recently, IEC 61850 supports the standardized communication technique in both station bus and process bus, and presents substation automation model. In order to implement the IEC 61850 based communication in a substation using the MU (merging unit) which is one of the important data acquisition equipments in substation automation, the time synchronization is demanded for cooperative operation between the devices. This paper proposes the precision time synchronization technique using IRIG-B protocol to develop the MU under IEC 61850 communication protocol. The proposed technique is implemented and its performance is verified experimentally.

IEC 61850 based substation automation system is operating under digital network with a number of IEDs and a HMI as relation of server and client. In case of IEDs, before implementing the system, all of the system integrators require IEC 61850 certificate from individual IED manufacture. Otherwise, there is nothing to verify IED for constructing substation automation system at the real substation. This paper shows verification strategy of IEC 61850 communication reliability such as association /release, report, dataset and four type control function.

IEC61850 which has comes to international standard for substation automation is designed with a station and process bus communication with Ethernet. In this paper, mentioning difference between official networks and substation networks, authors present the requirements for temperature, humidity and EMI characteristics. The properties which network switch should be satisfied and the technologies which make those requirements possible are also proposed. Additionally, we analysis the traffic pattern of communication services which IEC61850 supports. Based on the pattern, we propose a practical design example of IEC61850 based network for a 154kV substation.

As IEC 61850 based substation automation technology is emerging globally, there are many efforts to implement and apply this IEC 61850 standard to substation automation area. IEC 61850 based substation supports ethernet network, standard data model and SCL(substation Configuration Language), etc. These features can provide enough environment to make applied technology which can substitute the legacy relay trip logic configuration method(PLC or Local area reconstruction) to XML based configuration method. This paper suggests new IED trip logic configuration method. The XML based trip logic configuration method can be established using SCL technology And IED trip logic reconfiguration from remote center can be possible under ethernet based technology

IEC 61850 based substation automation system mainly consists of human machine interface as a client and a various of IEDs as a server. Both of them should require the field testing for performance verification including IEC 61850 communication services. This means that the test can assure the interoperability of IEC 61850 based substation automation system consisted of multi vendor's products. This paper shows a research result on the field test of the IEC 61850 based HMI and IEDs. And it proposes some engineering solutions for the system implementation.

Substation Automation System is basically operating throughout communicative services among IEC 61850 based devices. So, minimum requirement in order to install the system in the substation is to verify server and client conformance of IEDs and HMIs according to the IEC 61850 standard. Even though UCA IUG issued IEC 61850 conformance test procedures for both the server and the client, Much of the test is limited to IEDs as server and there is no client-only testing tool except KEMA server test tool sets. this study aims to develop IEC 61850 client testing system for verifying the full communication conformance of the substation automation system and this paper describes the design and implementation of the testing system.

한국전력은 IEC 61850 기반 변전소자동화(SA)시스템을 구축하기 위하여 2005년부터 단계별로 시범사업을 하면서 문제점을 개선하여왔다. 이러한 일련의 과정을 거쳐 2012년 후반부터는 신설 변전소에는 IEC61850기반 변전소자동화(SA) 시스템을 적용하기에 이르렀다. 이에 따라 IEC61850 기반 변전소 자동화에 대한 변전자동화 전문기술 양성을 위한 체계적인 로드맵을 수립하였고, 실설비와 연계된 모의고장시뮬레이터가 구비된 실습 시스템 구축이 필요하게 되었다. 본 논문에서는 KEPCO의 SA(Substation Automation) 전문인재 양성을 위한 IEC61850기반 SA 실습시스템 구축사례를 제시하였다. 본 SA 실습시스템을 활용하여 실제 변전소와 동일한 환경에서 교육을 수행함으로써 IEC 61850 SA 전문인재를 체계적이고 효율적으로 양성하여, IEC61850 SA 시스템을 조기에 정착할 수 있을 것으로 기대된다.
