Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, volume 26, issue 11, 2012, Pages 1~8
DOI : 10.5207/JIEIE.2012.26.11.001
The road lightings have made our living environment safe and active, since it was first installed in 1900 in Korea. As the industry developed, various kind of road lightings have been installed in an outdoor area. But the spilt light from the road lightings have caused health problem like the sleeplessness, the depression, the failure to thrive and the nearsightedness to children. The light trespass caused by road lightings vary with the height of road lightings, the distance from road lightings to the window and the BUG rating of road lightings. In this paper, we analyze the effect on the light trespass by the spatial installation position of road lightings using by RELUX program. And we derive the characteristics of the light trespass according to the spatial installation position of the road lightings in residential area near road.

Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, volume 26, issue 11, 2012, Pages 9~19
DOI : 10.5207/JIEIE.2012.26.11.009
The purpose of this study is to present the direction of LED lighting development to give people a comfortable feeling. For about 2 years, the database of daylighting color has been built by daylighting measurement and analysing hourly, monthly and seasonal change in daylighting colors. Finally, changes of color coordinates were drawn as a graph and it presented as the LED lighting color development indicator through the relationship with Plankian locus. This methodology is expected to contribute to the development fields of the LED lighting color.

The outdoor lighting is provided for a variety of purposes, for work or recreation, for safety or security, for amenity and for advertising or display. But the effects of lighting on the natural environment can be difficult to quantify. At present, in many countries, various policies to manage the light trespass from outdoor light have been planned. For example, Model Lighting Ordinance(MLO) will allow communities to drastically reduce light pollution and glare and lower excessive light levels. The recommended practices of the IES can be met using readily available, reasonably priced lighting equipment. So, it this paper, we analyze the effect of road lighting on light trespass using by RELUX program. And then we consider the possibility of practical application of BUG rating in Korea.

The characteristics of I-V and P-V of solar cell nonlinearly changes according to irradiation, temperature and load. Therefore, to use efficiently PV system, operating point must be always operating at maximum power point. Also, PV system is semiconductor, so it generates loss by temperature. But because of conventional MPPT methods are not considering temperature, it has problem which decrease efficiency. This paper proposes temperature measurement based optimal voltage(TMOV) MPPT algorithm using temperature measurement based optimal voltage. It analyzes characteristics of solar cell according to irradiation and temperature and conventional MPPT methods. The TMOV control algorithm proposed in this paper is compared and analyzed conventional MPPT methods. The validity of this paper proves using this result.

Most of existing wind turbine system is used with geared type; however, this type has lots of problems which are noisy, weight, maintenance and so on. In this paper, wind turbine system with fluid torque converter applied to solve these problems. In case of the proposed wind turbine system, it is possible to transmit torque to adaptable distance. So various sets including generator, inverter and auxiliary motor move from the nacelle to the ground. As a result, Total weight in Nacelle can be decreased. however, the efficiency can be decreased with fluid torque system. We also applied auxiliary motor to fluid torque system. So, we also realized rated revolutions and rated output windturbine and could get considerable good data.

Kim, Woo-Hyun ; Park, Chul-Woo ;
Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, volume 26, issue 11, 2012, Pages 54~61
DOI : 10.5207/JIEIE.2012.26.11.054
This study investigated the relationship between the response time of DVR (Dynamic Voltage Restorer) and the possible compensation range for voltage dips by the DVR system which protects the 3-phase phase-controlled rectifier from said dips. As a result, the permissible range of voltage dip is presented in a 3-phase phase-controlled rectifier. When the DVR compensates for voltage dip, the range of voltage dip can be compensated according to the DVR`s response time. Using the proposed method, DVR response time can be determined from the parameters of the 3-phase phase-controlled rectifier and the possible compensatory range of voltage dip, while at the same time it is possible to use a control system having an appropriate speed. Therefore, the use of excessively fast equipment can be avoided, improving the stability of the overall system. The reliability of the DVR concerning the 3-phase phase-controlled rectifier can be verified by simulation.

Chung, Dae-Taek ; Chae, Soo-Yong ; Hong, Soon-Chan ;
Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, volume 26, issue 11, 2012, Pages 62~74
DOI : 10.5207/JIEIE.2012.26.11.062
This paper proposes a new secondary battery charger/discharger available for zero voltage discharge which is used for test equipments and formation process. The proposed system is a switching type converter, and thus the system is high efficiency and more compact as compared with linear type charger/discharger. Conventional switching type charger/discharger can not discharge secondary batteries to zero voltage because of voltage drops in the switching elements and long distributing line(typically 10m). However, the proposed system is able to discharge the battery to zero voltage in constant current mode regardless of the voltage drops. In this paper, we analyze the proposed charger/discharger and the validity of the system is verified by simulation and experiment.

The basic processing unit for instant ramen noodles includes mixing, rolling, boiling, frying, cooling, and packing processes. For uniform thickness of dough sheets in rolling process, the roll-gap in rolling process needs to keep uniform thickness of flour sheets in spite of different kinds of raw materials. In this paper, we have developed a roll gap adjustment system using a PLC (Programmable Logic Controller) with a touch panel and an AC servo-mechanism to make dough sheets with a good gluten starch-network structure and uniform thickness and to contribute to process standardization by transferring from tacit knowledge of skilled workers to explicit knowledge. The developed system can adjust the roll gap in units of 0.01mm and correspond to various product items which have different thickness specification by recalling the presetting values of the desired thickness from database.
