IEC 61850 is a standard for power utility automation. Using IEC 61850 that uses ethernet may consume more costs for the automation than its value in small distribution substations. Thus, less expense and installation cost are required for the automation of small distribution substations. This study used inexpensive and easy-to-install IEEE 802.15.4 and implemented a bridge between IEC 61850 and IEEE 802.15.4, using Raspberry Pi to connect the existing IEC 61850. Using IEEE 1588, IEC 61850 traffic performances were evaluated, such as SV, GOOSE and MMS. Analyzing IEC 61850 requirements and performance evaluation results, the scope of application of IEEE 802.15.4 was decided.

This study uses sensors and Raspberry Pi to measure the values of current and voltage and transmits the measured sampled values to a network, carrying them in the frame of IEC 61850-9-2. A laboratory model was composed to send the sampled values, using the frame of IEC 61850-9-2. This study conducted a protocol analysis, using Wireshark for the accurate verification of the occurrence of the frame of IEC 61850-9-2. A visual analysis was conducted by displaying the received sampled values of current and voltage on the monitor in graphs. In addition, this study tested if the sampled values of IEC 61850-9-2 sent and received through the network equipment would meet the performance requirements of the message types of IEC 61850.

In this paper, problems and solutions are proposed for applying IEC 61850 to Distribution Automation System(DAS). Communication protocol integration in power automation system have issued by IEC standards, IEC 61850 of them has researched for applying IEC 61850 to many areas of power system in spite of that it was made for substation automation system. Especially, DAS is just about to apply IEC 61850 by communication network change from serial to ethernet although DNP 3.0 is used. But it's impossible to apply directly IEC 61850 to DAS by difference of environment which unfixed wide area and separated nodes in power distribution system unlike concept of IEC 61850 is made by Substation Automation System(SAS) environment of limited space. Thus, this paper proposed applications of three types which conceptual, practical, and future to consider problems and solutions when apply IEC 61850 to Ethernet based DAS.

TETRA(TErrestrial Trunked RAdio) is the wireless communication system generally adopted to public network and backbone network, as the technology of Trunked Radio System specified by ETSI(European Telecommunications Standards Institute) and currently adopted to the Electric Power IT Backbone Network in Korea. IEC 61850 is the protocol proposed for SAS(Substation Automation System) of SCADA(Supervisory Control And Data Acquisition) system. In this paper, IEC 61850 Server and Client simulator are used based on Linux operating system. The multi-functional gateway, which transforms the communication based on TCP/IP between IEC 61850 Server Simulator and Client Simulator to the one based on TETRA Packet Data Service, is developed such that IEC 61850 SCADA system is constructed based on TETRA.

There are many types of power facilities such as transformers, switches, and energy storage devices in the micro grid environment. However, with the development of IoT technology, opportunities to acquire sensor information such as temperature, pressure, and humidity are provided. In the existing micro grid environment, the communication protocols such as MMS transport protocol in IEC 61850 standard is applied in accordance with the integrated operation between the power facilities and the platform. Therefore, to accommodate IoT data, a gateway technology that can link IoT data to a data collection device (FEP) based on IEC 61850 is required. In this paper, we propose IEC 61850 based IoT gateway platform prototype for microgrid operating system linkage. The gateway platform consists of an IoT protocol interface module (MQTT, CoAP, AMQP) and database, IEC 61850 server. For databases, We used open source based NoSQL databases, Hbase and MongoDB, to store JSON data. We verified the interoperability between the IoT protocol and the IEC 61850 protocol using Sisco's MMS EASY Lite.

IEC 61850은 변전소 자동화 시스템에 관한 국제표준문서이다. IEC 61850의 특징의 중의 하나로서 GOOSE가 있다. GOOSE는 변전소기기 간에 빠르고 신뢰성을 보장하여 기기들 간의 정보교환을 위한 IEC 61850 통신 서비스이다. IED는 GOOSE 메시지를 통해 트립 신호와 같은 중요한 정보를 전송한다. 현재 몇몇의 IEC 651850 기반의 기기들이 개발되었고, 한국에서는 IEC 61850 기반의 IED를 개발하고 있다. IEC 61850 표준문서에서 오류, 모호한 점 그리고 추가할 점들이 발견되고 있다. 이러한 문제들은 Technical Issues라 부른다. 이 논문은 IED 개발업자 또는 검사자에게 IEC 61850과 관련된 좀 더 나은 이해와 견해를 제공하기 위하여 GOOSE에 관한 기술적 이슈를 조사한다.

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.

In this paper, a substation HMI based on IEC 61850 is proposed that uses SCL to have all information in substation to include standard concept of IEC 61850. A proposed substation HMI using SCL based on IEC 61850 expresses different display by each substation structure and component device change in substation. A proposed substation HMI is designed by IEC 61850 standard, and it suits for future substation HMI based on IEC 61850. A proposed HMI is proved by a program that is made by Visual C++ to use SCL file based on XML.
