IEC 61850 based substation automation system mainly consists of a various of protective and control IEDs. In order to implement the system, All of them should require the performance verification of IEC 61850 communication services for the assurance of interoperability throughout the digital network. This paper shows a research result on the testing method of IEC 61850 control communication interface of IEDs according to IED IEC 61850 conformance test procedures.

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.

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.

IEC 61850 기반의 디지털 변전소를 구축하기 위해서는 가장 중요하고 고려해야 하는 것은 IED의 통신서비스를 이용한 기능 구현이 국제 규격인 IEC 61850에 따라 적합하게 이루어 졌는지를 확인 사항이다. 하지만 변압기 Tap의 위치정보를 정수형의 데이터로 표현하는 지능형전자장치의 IEC 61850 변압기 Tap Changer의 제어에 대한 적합성 시험에 대한 내용 및 방법은 현재 국제 IEC 61850 적합성 시험에서는 포함하고 있지 않으며, 이를 실제 수행할 수 있는 시험장치도 존재하지 않는 상황이다. 따라서 본 논문에서는 변전자동화시스템에 적용되는 지능형 전자장치의 Tap Changer 기능이 IEC 61850 통신서비스를 통해 이루어질 경우 이에 대한 국제규격을 기반으로 하는 적합성 시험을 수행할 수 있는 방안에 대한 설명하고자 한다.

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.

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.

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.

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.
