Voltage Sag 발생에 따른 가변속구동장치의 동작 분석
백정열(Jeong-Yeol Baek),서훈철(Hun-Chul Seo),김철환(Chul-Hwan Kim) 대한전기학회 2010 대한전기학회 학술대회 논문집 Vol.2010 No.11
Voltage sag 발생에 따른 가변속구동장치(Adjustable Speed Driver, ASD)의 동작 특성을 분석하였다. 가변속구동장치의 각 구성요소는 전력계통 과도현상 해석 프로그램인 EMTP/ATP Draw를 이용하여 모델링하였다. 이를 배전계통에 연결하여 다양한 크기를 갖는 voltage sag를 시뮬레이션 하였으며, 각 경우에 대한 가변속구동장치의 동작을 분석하였다.

Backgrounds: It has been investigated about ageing theory. However, ageing mechanism still remains to be unknown. Since Harman proposes that ageing and ageing related diseases might be due to oxidative damage and these are modifiable by genetic and environmental factors. For designing an optimal nutritional countermeasure against ageing and ageing related disease, it is necessary to understand the ageing mechanism and other reactive species. Objectives: Schizandra Chinesis has been clinically used to treat brain disease, respiratory or inflammatory disease etc. in Oriental medicine. The purpose of this study is to investigate the scavenging effect of Schizandrae Fructus herbal-acupuncture solution(SFHA) on NO, DPPH and IL-4. Results: The results are summarized as follows; ① There is a significant scavenging effect of SFHA on NO in 0.1, 1, 10㎎/㎖group after 24hrs. ② There is a significant scavenging effect of SFHA on DPPH in 1, 10㎍/㎖group. ③ There is a significant inhibitory effect of SFHA on IL-4 in 1, 10, 100㎍/㎖group. Conclusions: These findings indicate that SFHA can be used as antioxidant or antiimflammatory drug. But further study is needed about the effect of SFHA.

In the present study, СаСО<sub>3</sub> powder was prepared from the flyash obtained from municipal solid waste incinerator (MSWI). Flyash obtained from the dust collector in stoker-type MSWI is used to selectively dissolve CaO by using sugar solution. After filtration, CO<sub>2</sub> gas was pass through the dissolved solution to produce CaCO<sub>3</sub> powder. It was found that the optimum conditions for CaO dissolution were solid content 10%, reaction time 15 minutes, sugar concentration 10-15%, etc. In the present work, the high-grade CaCO<sub>3</sub> powder was obtained and the experimental conditions are discussed.
