Noh, Tae-Kyu ; Lee, Yong-Wook ;
Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, volume 27, issue 2, 2013, Pages 1~6
DOI : 10.5207/JIEIE.2013.27.2.001
In this paper, we implemented a polarimetric strain sensor using a Sagnac birefringence interferometer composed of a polarization-maintaining photonic crystal fiber (PM-PCF). By changing the length of the PM-PCF employed as the sensor head of the proposed sensor, the length dependence of the strain sensitivity was investigated. With respect to 5.0-, 7.5-, and 10.0-cm-long PM-PCFs, strain measurements were done in a measurement range of
, and strain sensitivities of ~2.04, ~1.92, and
were obtained, respectively. If an ideal PM-PCF with no length dependence of a modal birefringence is used for the proposed sensor, the strain sensitivity is independent of the length of the sensor head (PM-PCF). In the practical PM-PCF used in experiments, however, a shorter PM-PCF has a higher length dependence of the modal birefringence due to its imperfectness and nonuniformity of the internal structure, resulting in a higher length dependence of the strain sensitivity.

Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, volume 27, issue 2, 2013, Pages 7~13

The portion of lighting power consumption for our country is up to 20~30% of the total amount. Currently, most of the DSM(Demand side management) of lighting power is delivered in supply of high efficient lighting to customers. On the contrary, applications of lighting power to power load leveling are still rare. In this paper, the simulations for various control types of lighting power for load leveling are tried, and we obtained the cost effective and optimal control method through that. This simulation was executed in test office with fluorescent light by us based on applying 8 control types(on, off & dimming), considering customers' satisfaction, for instance, minimum intensity of illumination allowed. According to the result of this test, we found that mixed type(chessboard(on-off) plus dimming control(10%)) is most effective.

Today, energy problem has become an important issue, and a development of renewable energy is urgent. In architectural fields, a research of the energy efficient lighting system using renewable energy is in progress. The energy efficient lighting system could be realized by integrating a daylight responsive LED lighting control system and a blind PV system. This system is able to save and generate electric energy. Efficiency of this system depends on control methods of blind PV. As a preliminary research, this research analyzed power generation and inflow of available daylight according to control method of blind PV.

Lee, Juchan ; Eom, Jinseob ;
Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, volume 27, issue 2, 2013, Pages 22~28
DOI : 10.5207/JIEIE.2013.27.2.022
In this paper, the low cost SOA Dimming Driver which consisted of LabVIEW programming part capable of current pattern design, DAQ module for analog voltage output, and voltage to current converter has realized. The output current(possible to 3A) from the Driver was clearly constant without ripple and also showed no variance until 1mA unit for a long time operation. The proposed low cost Driver can replace the previous high cost SOA Drivers for wavelength swept lasers fully and provide the convenience and safety of auto-supplying a designed current pattern.
Energy Coordination of Cascaded Voltage Limiting Type Surge Protective Devices
Lee, Bok-Hee ; Shin, Hee-Kyung ;
Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, volume 27, issue 2, 2013, Pages 29~35
DOI : 10.5207/JIEIE.2013.27.2.029
For the purpose of designing and applying optimum surge protection, one of the essential points is to take into account the energy coordination between cascaded surge protective devices(SPDs) and it is important to obtain an acceptable sharing of the energy stress between two cascaded SPDs. In this paper, in case of two voltage-limiting SPDs connected in parallel, the amount of splitting impulse current and energy that flow through each SPDs is investigated as a function of the protective distance. As a result, the energetic coordination between cascaded SPDs is strongly dependent on the voltage protection level of SPDs and the protective distance. It was confirmed that the sharing of the energy between two cascaded SPDs and the limited voltage levels are appropriate when the voltage protection levels of both upstream and downstream SPDs are the same.

Ko, Jae-Sub ; Chung, Dong-Hwa ;
Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, volume 27, issue 2, 2013, Pages 36~44
DOI : 10.5207/JIEIE.2013.27.2.036
This paper proposes the reconfiguration of PV module considering shadow influence of photovoltaic system. The PV system is consisted series-parallel connection of PV module. The voltage and current between PV modules become unbalance when shadow occurs to PV module. If shadow occurs to the series connection PV module, the output current is limited to current of shaded PV module. Also if shadow occurs to the parallel connection PV module, the output voltage is limited to voltage of shaded PV module. These problems are caused power loss. Therefore, the PV module in this paper consist using the fixed module and variable module by shaded conditions. The reconfiguration of PV module can compensates the shadow influence by changing connection of a variable module when shadow is occurred to PV module. A validity of the reconfiguration of PV module proposed in this paper proves through comparing with performance of conventional PV module.

Lee, Sang-Woo ; Kang, Jin-Kyu ; Lee, Dong-Ha ; Park, Tae-Joon ;
Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, volume 27, issue 2, 2013, Pages 45~53
DOI : 10.5207/JIEIE.2013.27.2.045
In this paper, we analyze the typical phase voltage and line current waveform characteristics of the distribution system with 3 phase small synchronous generation source in case with load and non-load group, in order to investigate the power quality for end load connected of generation source. As demonstrated by our experimental results, the distortion and power quality of phase voltage and line current waveform were relatively good for low voltage 3 phase model grids connected of 3 phase small synchronous generation source in case with non-load group. However, distortion and power quality of voltage and current waveform was poor for low voltage 3 phase model grids connected to 3 phase small synchronous generation source in the load group with some phase voltage and frequency difference. From the above results, we conclude that the phase voltage and frequency of 3 phase generation source must be identical to that of distribution system source to maximize the power quality. Also, special attention is required in case of having load group or non-load group to 3 phase generation source.

Lee, Bok-Hee ; Lee, Kang-Soo ; Kim, You-Ha ; Um, Sang-Hyun ;
Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, volume 27, issue 2, 2013, Pages 54~61
DOI : 10.5207/JIEIE.2013.27.2.054
This paper presents transient response behavior and frequency-dependent ground impedance of a single carbon ground electrode. The ground impedance of the carbon ground electrode was measured as a function of frequency of injected currents and simulated by using the distributed parameter circuit model with due regard to the frequency-dependent soil parameters, and the transient response behavior of the carbon ground electrode against impulse currents were investigated. As a consequence, the frequency-dependent ground impedance of the carbon ground electrode showed the capacitive behavior, that is, the ground impedance decreases with increasing the frequency of injected currents and lowers at the fast front time of impulse current. It was found that the carbon ground electrode is effective in grounding system for lightning protection. The ground impedance simulated with due regard to the frequency-dependent soil parameters was in good agreement with the measured data. The adequacy of the simulation technique and the distributed parameter circuit model for the carbon ground electrode was verified. It is expected that the simulation methodology, which analyzes the frequency-dependent ground impedance of the carbon ground electrode proposed in this work, can be used in the design of a grounding system for protection against lightning.
A DVR Control for Compensating Unbalanced Voltage Dips of a DFIG System using Zero Sequence Components
Thinh, Quach Ngoc ; Ko, Ji-Han ; Kim, Dong-Wan ; Kim, Eel-Hwan ;
Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, volume 27, issue 2, 2013, Pages 62~68
DOI : 10.5207/JIEIE.2013.27.2.062
The dynamic voltage restorer (DVR) is an effective protection device for wind turbine generators based on doubly-fed induction generator (DFIG) that is operated under unbalanced voltage dip conditions. The compensating voltages of the DVR depend on the voltage dips and on the influence of the zero sequence component. The zero sequence component results in high insulation costs and asymmetry in terminal voltages. This paper proposes the use of a proportional-resonant controller in stationary reference frames for controlling zero sequence components in the DVR to protect the DFIG during unbalanced voltage dips. To enhance the proposed control method, a comparison is carried out between two cases: with and without using the control of a zero sequence component. Simulation results are presented to verify the effectiveness of the proposed control method by using the Psim simulation program.
Digital Control of Low-Frequency Square-Wave Two-Stage Electronic Ballast for HID Lamps with Resonant Ignition and High Efficiency
Lee, Woo-Cheol ;
Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, volume 27, issue 2, 2013, Pages 69~76
DOI : 10.5207/JIEIE.2013.27.2.069
In this paper, electronic ballast using resonant inverter for HID lamp is designed and implemented. The proposed electronic ballast is used the soft switching technology ZVS(Zero Voltage Switching) to reduce turn-on and turn-off loss. The ignition of proposed electronic ballast is achieved by controlling a full bridge inverter which is consisted of LC filter for resonance. After ignition the ballast operates as a low frequency square wave inverter by controlling a full bridge inverter as a buck converter. After ignition at resonant frequency of
=160kHz, the switching frequency of a buck converter is consisted of 50kHz of high frequency and 170Hz of low frequency. This is for attenuating high frequency harmonics and avoiding acoustic resonance. The experimental results show that electronic ballast using resonant inverter is operated stably.
The Study on Emission Spectrum Characteristics of Atmosphere Pressure Plasma
Park, Sung-Jin ;
Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, volume 27, issue 2, 2013, Pages 77~83
DOI : 10.5207/JIEIE.2013.27.2.077
In this study, we aimed to determine the optical properties of the plasma used for the dry cleaning method. The optical properties of the atmospheric pressure plasma device were measured through the degree of ionization of hydrogen or nitrogen gas by ionized atmospheric gas. The degree of ionization of hydrogen or nitrogen is closely associated with surface modification. We observed through our experiments that argon gas, an atmospheric gas, caused an increase in the ionization of nitrogen gas, which has similar ionization energy. This type of increase in nitrogen gas ions is believed to affect surface modification. The results of our study show that the pressure of argon gas and the partial pressure of argon and nitrogen gases lead to different results. This important result shows that argon ions can affect the ionization of nitrogen gas.

DOI : 10.5207/JIEIE.2013.27.2.084
In case when the existing TRIAC phase controlled dimmer is drove for the LED lighting equipments, there are many problems such as the LED flicker in low phase-angles, the acoustic noise and elements damage by increase of the peak voltage in the input filter capacitor, mulfunction by insufficiency of the TRIAC holding current, and the abnormal oscillation by LC resonant. In this paper, we proposes the single-stage quasi-resonant PSR(Primary Side Regulation) PWM converter, and the design, the simulation and experiment are performed. As a result, it could confirm that the proposed PWM converter is the lighting equipments for LED drive which can alternate the existing 60W class incandescent bulbs and it has the high drive performance of the efficiency 80% and over, the power factor 0.95 and over under the normal voltage 220V. Finally, total harmonic distortion(THD) is gratified with a standard of the lighting equipments and the durability is evaluated as the high reliablilty of 150,000 hours and over.

Lee, Bok-Hee ; Kim, Ki-Bok ;
Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, volume 27, issue 2, 2013, Pages 95~101
DOI : 10.5207/JIEIE.2013.27.2.095
This paper presents the comparison of the earth resistivity obtained from the measurements made with the three-electrode and four-electrode fall-of-potential techniques. The
curve obtained from Wenner four-electrode method in undisturbed earth is in good agreement with the
curve obtained from the three-electrode method based on the fall-of- potential method. However, The
curve in disturbed earth with moisture and freezing is significantly different with the
curve is considerably sensitive to the freezing and the moisture present in the earth surface compared to the
curve. Thus to determine the actual earth resistivity, it is necessary to take into account the earth surface conditions when measuring the earth resistivity.

Kim, Hyunseob ; Han, Jungho ; Song, Joong-Ho ;
Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, volume 27, issue 2, 2013, Pages 102~109
DOI : 10.5207/JIEIE.2013.27.2.102
In this paper, a new torque predictive control method of interior permanent magnet synchronous motor is developed based on an extended rotor flux. Also, a duty ratio prediction method is proposed and allows the duty ratio of the active stator voltage vector to be continuously calculated. The proposed method makes it possible to relatively reduce the torque ripple under the steady state as well as to remain the good dynamic response in the transient state. With the duty ratio prediction method, the magnitude and time interval of the active stator voltage vector applied can be continuously controlled against the varying operation conditions. This paper shows a comparative study among the switching table direct torque control(DTC), the SVM-DTC, conventional torque predictive control, and the proposed torque predictive control. Simulation results show validity and effectiveness of this work.

Shin, Hansu ; Song, Hye-Jin ; Byun, Jin-Kyu ;
Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, volume 27, issue 2, 2013, Pages 110~119
DOI : 10.5207/JIEIE.2013.27.2.110
As the technologies such as middle-range resonant WPT (wireless power transfer) advance that utilizes medium and low-frequency magnetic field, the importance of safety of such magnetic field is growing. The research on the effect of electromagnetic field on the human body has been mainly done on the GHz range of mobile phones, or 50~60Hz range of electric power systems. However, there has been relatively few works on the 100kHz~10MHz range used in the resonant wireless power transfer. Since there is a difference in the limiting value of magnetic field between widely used ICNIRP EMF guideline and IEEE C95.1 standard, there can be possible confusion when establishing EMF (Electromagnetic Field) standard on the wireless power transfer device in the future. In this paper, the induced current in the human body, which is the basic restriction of the EMF guideline, is calculated using Quasi-static FDTD method when 3D high-resolution human model is exposed to the 100kHz~10MHz magnetic field. Using this result, the feasibility of the magnetic field reference level in the ICNIRP guideline is analyzed.
