한국전력공사에서는 2013년도부터 154kV급 변전소를 IEC 61850 기반의 변전소 자동화 시스템을 구축 운영중이다. 현재 구축 운영중인 디지털 변전소는 Station Level의 자동화 시스템이며, Process Level의 Full Digital 디지털 변전소 구축은 연구과제 성과물의 신뢰도 검증과 관련 기술 신뢰성 확보 시 구축예정이다. 본 논문에서는 Full Digital 변전소 구축을 위한 Process Level의 IED 및 엔지니어링 프로그램 개발에 대한 결과와, 개발된 시작품의 현장 실증 환경 구축에 대해 논하고자 한다.

The purpose of this study is to develop an economical radiation sensor using photo diodes. An electronic circuit was developed. The behavior of the radiation sensor was evaluated by increasing number of photo diodes. The sensor became more reliable by the increase in number of photo diodes. It was showed that the photo diodes sensor would be applicable.

In order to provide basic information for the estimation of reference crop evapotranspiration in the greenhouse, an lysimeter experiment was performed. Kenturky Blue Grass was used as a reference crop. Relationships between measured reference crop evapotranspiration and weather factors were analyzed. A multi-regression model was developed and tested.
