  • 배전계통을 효율적으로 운영하기 위해 배전자동화 시스템에는 여러 어플리케이션들이 탑재되어 있다. 대부분의 어플리케이션들은 그 기능을 수행하기 위해 기본적으로 부하 데이터를 필요로 한다. 현재 배전계통 부하 관리는 제한적인 데이터를 이용해 산정하고, 하나의 값으로 관리되고 있다. 그 결과 어플리케이션들의 기능을 효율적으로 사용하지 못하고 있다. 본 논문에서는 실시간 측정 데이터를 이용하여 부하데이터를 관리하는 방법을 제안하여 부하 데이터의 신뢰도를 향상시킬 수 있는 방법을 제안하고 있다.

  • 전력선통신(PLC : Powerline Communication)을 기존에 이용되고 있는 통신 기술과 접목할 경우 각 통신 방식 간의 단점을 상호 보완할 수 있어 신뢰성, 유연성, 확장성이 우수한 배전계통의 자동화용통신시스템을 구성할 수 있게 된다. 이를 통해 배전계통의 자동화와 안정화를 이룰 수 있어 무정전, 고품질의 전력 공급이 가능해지며, 지상변압기 감시제어시스템, 원격 전력조정시스템, 전력품질 감시시스템 등 향후 도입될 다양한 배전계통의 자동화시스템 구성에 있어 통신망 임대비를 획기적으로 절감할 수 있게 된다. 본 논문에서는 전력선통신을 기반으로 한전 TRS와 위성망, 그리고 케이블, 광통신망을 통합함으로써 신뢰성이 높고 유연성이 뛰어난 복합통신 시스템을 제안하고자 한다.

  • The BEF on the radial distribution line refers to a class of ground faults in which the load-side power line only is grounded, with the distribution line broken into two parts, the source-side and the load-side. Because its mechanism is remarkably different from that of other earth faults, the fault current is very low, and then difficult to detect the BEF. Thus, it is necessary to analyze its properties and to find an appropriate method that can economically protect the BEF of nonautomation area in the substation. As a result of analyzing the BEF data obtained by the RTDS, EMTP simulation, and the field test data of ETSA, we believe that it is the dominant factor in distinguishing the BEF from normal conditions by a criterion value that is appropriately handled from the zero-sequence current. Thus, with this criterion value, a BEF detecting algorithm is constructed which measures the variations of the zero-sequence current and processes then properly so as to make the fault decision. To prove the accuracy of this algorithm, it is compared with the field test data of ETSA under various conditions. The results show that the proposed algorithm is accurate.

  • This paper presents active management of feeder automation systems using active database. DAS(Distribution Automation System) has been managed for feeder automation in passive manner. Therefore, feeder automation system has to be managed by operator when feeder overloadings is detected. It may be possible for propagating the feeder overloadings area by operator's mistake. To overcome this defect, the author proposed the feeder automation technique with active manner to obtain feasible feeder reconfiguration. Active database can manage feeder automation system by data driven monitoring of events and by corresponding actions without operator's intervening. To manage feeder automation system with active manner, production rule, active rule manager are designed. And active database system architecture for feeder automation system is proposed. Test results on the KEPCO's 108 bus distribution system show that the performance is efficient and robust.

  • We overview the current distribution automation system in Korea and point out the limitations of the distribution services which can be provided by the current system. In this paper we propose a new distribution system architecture which is based on the peer-to-peer communication model. In this decentralized architecture the intelligent FRTUS can initiate data transmission without any interruption of a central server, and can exchange data with other FRTUS as peers. In order to support the peer-based distribution system, we specify the requirements for new communication network and suggest a way of improving the current distribution network where we adapt an intelligent module for protection and restoration, called MASX, and utilize the open communication network protocols. We also show how the new architecture can enhance major distribution services such as protection, automatic restoration, and equipment management.

  • OPC UA(IEC62541) is a communication protocol for SG(Smart Grid) application platform. It was standardized by IEC TC57 group in December 2012. The IEC61850 has been used in Digital Substation Systems and Smart Distributed Systems. The DNP3.0 has been used for device's data collection/control in Distributed Systems. The DLMS/COSEM has been used to control metering and collect information in the Smart Metering. The top-level SG management platform needs an independent middleware to manage transparently the Power Information Technology, including the IEC61850, DNP3.0, DLMS/COSEM. In this paper, we propose the SDG(Scada Data Gateway) platform. It manages Power Information Technology based Digital Substation Systems and Smart Distributed systems, Smart Metering through OPC UA.
