At this study, we are developing a possible control system through remote monitoring for fire protection in various chemical factory facilities. It's possible to do real time confirmation of a normal operation presence of the various equipment installed in a chemical factory through the internet network at a fire fighting head office, an area fire department and a chemical factory situation room using this remote monitoring control system. When occurring, abnormal operation is the remote monitoring control system, which can check this immediately and notify the situation room administrator. After it was tested using developed remote monitoring control system, the remote monitoring for which the internet network was used confirmed possible.

Major utilities have been focusing on R&D and nationwide business of AMI system which plays a vital role in SmartGrid whose concept is to maximize energy efficiency and optimize electric power facility management with exchanging real time information between utilities and consumers based on ICT technologies in power grid. In this paper, we suggest a power loss monitoring method using KEPCO's AMI system which is operating in fields and with the acquisition of AMI data and analyses verify the validation of a power loss monitoring method.

The importance of total management for maritime structures (Ports, Piers, docks. marine bridges, marine roads, submarine pipelines, etc.) is more and more increasing in these days. Especially, in spite of the marine structures are exposed at the various corrosion circumstances, there are not only a standard of Cathodic Protection System but also knowledge of importance for necessity of corrosion monitoring. Therefore, this paper presents the results of development for the Remote Real-Time Corrosion Monitoring and Control System Using by TRS on Maritime Metallic Structures which can be prevents a big accident by corrosion.

The owner of metallic structures has a burden of responsibility for the protection of corrosion and the prevention against big accident such as gas explosion or collapse of bridge and building and so on. So, he has been spent the money and the time for corrosion monitoring and analysis of measuring data. Therefore, KERI(Korea Electrotechnology Research Institute) has developed the real-time wireless remote corrosion monitoring system using by TRS(Trunked Radio System). The results of development for corrosion monitoring system are described briefly. Especially, the interfacing technology between the server and rectifier introduced in this paper.

In present, most of metallic structures (gas pipeline, oil pipeline, water pipeline, etc) are running parallel with subway in Seoul and Pusan.In this case, subway system make a stray current due to electrical corrosion on metallic structures. The owner of metallic structures has a burden of responsibility for the protection of corrosion and the prevention against big accident such as gas explosion or soil pollution and so on. So, they have to measure and analyze the data about P/S(Pipe to Soil) potential, amplitude of stray current, point of source of stray current and so on. In this paper, results of development about Wireless Remote Monitoring and Control System on Underground Pipeline in Stray Current Conditions are presented. And also field test data should be reporting.

최근 변전소 자동화 시스템에서 가장 큰 관심사는 종래의 인간의 개입을 최소화 할 수 있는 통합화, 자동화, 원격 감시화이다. 즉 변전소를 구성하는 장비들은 서로 다른 구조와 통신방식에서 벗어나 IEC61850 표준규격에서 제안하는 객체 모델링 및 통신프로토콜을 이용한 마이크로프로세서 기반의 IED를 개발하여 상호운용성을 확보하는 것이다. 본 연구에서는 IEC61850기반의 간단한 과전류 계전 IED(OCR)를 개발하고 그 구현방법을 설명하였다. 구현을 위해 상용보드인 MVME5100에 실시간 운영체제인 VxWorks를 포팅하여 MMS(Manufacturing Message Specification), SMV(Sampled multicast value) GOOSE(Generic object oriented substation event) 통신모듈을 탑재하였고 과전류 계전 요소들을 논리장치 및 논리노드로 구현하였다. 또한 전력계통 시뮬레이터인 Hypersim을 이용하여 IEC61850기반의 리클로저, 액츄에이터, 병합장치를 구현하고 과전류 계전 IED의 성능을 검증하였다.

배전계통 원격감시제어 기능을 수행하는 배전자동화 주장치 운영S/W는 정확한 개폐기 제어를 위해서 사용자에게 정보를 쉽고 빠르고 명확하게 전달해야 함을 기본으로 하고 있다 1998년 처음 도입된 소규모 배전자동화 시스템은 해가 거듭될수록 현장의 다양한 요구가 발생하게 되었고 이를 해소하고자 S/W 성능개선을 추진하게 되었다. 본 논문에서는 S/W개선내용을 GUI변경을 통한 편의성향상과 중요현황 및 통계화면 추가로 조작의 신뢰성향상, 조작 전 재확인절차 추가 및 데이터 손실방지 등의 안정성을 향상시켜 신속한 고장파악 및 정확한 고장복구로 안정된 전력공급에 기여할 수 있을 것으로 사료된다.

This paper describes the standardization of remote monitoring and controlling system for nursery electrical facilities. The proposed system have three operating modes of motoring, controlling, and fault-notifying. In fault-notifying mode, the local unit is designed to send messages on failure of the electrical facilities to the central computer, mobile phone, and pager. Also, the local unit is consisted of 24-input and 8-output port needed for monitoring and controlling the facilities. With the use of this standardized system, we could expect the effective management in every phase of nursery facilities.

A diagnostic methodology, which utilizes only the remotely-measurable signals, has been requested to be developed in order to evaluate and monitor conditions of MOVs. It is proven that the stem thrust are the most important variables which provide the operability of MOVs. Therefore the stem thrust estimator was developed and validated, which estimates stem thrust by use of the motor torque. The motor torque is calculated using electrical signals which can be measured in Motor Control Center(MCC). (omitted)

In general, wireless sensor networks composed of many nodes which are located in ad. hoc environment and send the gathered data to sink node support only one way traffic. In those cases, it is not possible to send commands to nodes to react for exceptional events because the networks can not deliver downward data and the nodes run in pre-assigned fixed schedule. This paper expands the WSLP to bidirectional WSLP and implements a fire monitoring system on it, and shows the feasibility of bidirectional USN by demonstrating the usability of the process of reaction to a fire in the implemented fire monitoring system.
