전자식 전력량계와 무선모듈을 이용한 전력품질 표시 및 모니터링
정득일(DEUG IL JUNG),손영대(YOUNG DAE SON) 대한전기학회 2007 대한전기학회 학술대회 논문집 Vol.2007 No.10
An electronic watt-hour meter with high-precision measurement technology can provide many valuable metering data of a real-time system measurements, such as per-phase voltage, ampere, active power, reactive power, apparent power, power factor, and system frequency. Also many of accumulated metering data such as active energy, reactive energy, apparent energy, and load profile can be gettable from an electronic watt-hour meter[1]. This paper presents an approach of the small-sized AMR (Automatic Meter Reading) that provides customers with a very valuable electrical service. This AMR service transmits lots of a valuable metering data by using Zig Bee communication module, so that users resided in their premises can use the information to audit a power quality and improve their electrical conditions by using the PQ monitoring device equipped with ZigBee receiver. This PQ monitoring device shows metering data on LCD and transmits to the PC through an internal network. Also, the device can keep the valuable meter data into a built-in non-volatile memory. The final goal of this paper is to better understand the power quality of electrical systems and offer the power quality information for the convenience of all power consumers.

전력산업의 스마트그리드화에 의한 유용성과 용이성이 사용 의도에 미치는 영향
정득일(Deug-IL, Jung) 실천경영학회 2017 실천경영연구 Vol.12 No.1
The recent issues, such as atmospheric contamination by exhaust fumes, which have been globally raised, required that the electrical power use system should be managed more scientifically and that researches on the electrical smart grid are necessary. Accordingly, in this research, the empirical analysis was performed on whether or not the theory of planned behavior has effects on the value convenience and the intention of use of the users of the electrical smart grid. A total of 344 questionnaires were distributed and 294 questionnaires, which accounted for 85.46% of the entire questionnaires, were collected, and excluding 20 defective questionnaires, the final 274 effective questionnaires were used for the statistical analysis. First, the results of analyzing the hypothesis that the theory of planned behavior will have effects on value convenience showed that it has statistically significant effects on the usefulness in which attitude is perceived Second, the results of analyzing the hypothesis that the perceived ease will have effects on the perceived usefulness showed that the perceived usefulness has statistically significant effects on the perceived ease. It was found that the theory of planned behavior has significant effects on the perceived usefulness and the perceived ease Third, the results of analyzing the hypothesis that the value convenience will have effects on the intention of use showed that the perceived ease and the perceived usefulness have statistically significant effects on the intention of use
