Since the "Light Pollution Prevention Act" was executed, the installation of the light cutoff panel to the security lightings which caused light trespass has been increased in the local government. The light cutoff panel is effective in reducing the light trespass in term of the cost-benefit. Because the installation of the light cutoff panel is inexpensive than the change of the security lighting. But the reflected light from the surface of the light cutoff panel has been regarded as another light pollution problem to solve. Therefore, we try to improve light cutoff panel by changing the light reflectivity characteristic of the surface of the light cutoff panel. First, we laminated the surface of light cutoff panel by black powder to reduce the light reflectivity of the light cutoff panel. After the black powder lamination, the light reflectivity on the light cutoff panel improved from 85% to 5%. And we compared reflected light caused by black powder laminated light cutoff panel with the one of no surface treatment cutoff panel. The vertical illuminance was measured at 3, 6, 9m in front of the security lighting and 3, 6, 9, 12, 15, 18m in back of the security lighting to evaluate the reflected light. And the measurement height was determined of 1.5m considering the height of the 1th floor of an apartment house. In this study, we found that the reflected light from the light cutoff panel can be reduced about 90% by the black powder lamination method. The results derived from this study will be helpful to develope the various kind of light cutoff panel which minimize the adverse effect like reflected light of light cutoff panel.

This paper proposes the integration of photovoltaic (PV) and energy storage systems for sustained power generation. In this proposed system, whenever the PV system cannot completely meet load demands, the super capacitor provides power to meet the remaining load. A power management strategy is designed for the proposed system to manage power flows between PV array systems and supercapacitors (SC). The main task of this study was to design PV systems with storage strategies including MPPT with direct control and an advanced DC-link controller and to analyze dynamic model proposed for a PV-SC hybrid power generation system. In this paper, the simulation models for the hybrid energy system are developed using Matlab/Simulink, SimPowerSystems and Matlab/Stateflow tool.

Recently, Concerns of imbalance for power supply has been raised by the increase of electric power consumption, but the interest of electric safety is still lacking due to the incompleteness of regulations. Particularly, Arcing fault, direct cause of electric fire accidents, is difficult to detect, interrupt due to unformal signal behaviour in previous research and apply to real system. In this paper, Arcing fault simulator device was fabricated to investigate the characteristics of series arcing fault and simulated the faults in various real load. Also, this study are analysed arcing fault signal by using the harmonic analysis of the acquired data from the current of the power supply and proposed the methods to prevent the series arcing fault accidents in advance.

The photovoltaic power system is performing power generation by being installed in outdoors. Therefore it has the characteristics affected by environmental factors. In particular, if the solar power generation facility connected to the grid, the power can be generated continuously in a state of being secured operating voltage of the inverter and solar irradiation. In that case, if an abnormal situation such as flooding or heavy rains has occur, the possibility of electric shock or damage of facilities due to current leakage or a floating matters is present. In this paper, we performed electrical safety assessment about the connection part, junction box and cable of the solar module when the solar power system was flooded. we also assessed whether or not the leakage current is occurred in case of the cable was damaged. As a result, in case of the leakage current is large, we can be known that it is the risk of electric shock as well as cause of inverter damage.

The Study on Detecting Scheme of Voltage Sag using the Two Difference Voltage
Lee, Woo-Cheol ;
Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, volume 28, issue 12, 2014, Pages 65~73
DOI : 10.5207/JIEIE.2014.28.12.065
In this paper, the detection scheme of the voltage variation using a two difference voltage is proposed. The conventional sag detector is from a single-phase digital phase-locked loop (DPLL) that is based on a d-q transformation using an all-pass filter (APF). The APF generates a virtual q-axis voltage component with
phase delay but the APF cannot generate the virtual q-axis voltage depending on the phase of the grid voltage. To overcome the problem, q-axis voltage component is generated from difference between the current and previous value of d-axis voltage component in the stationary reference frame. However, the difference voltage around the zero crossing is not enough to detect the voltage sag. Therefore, the new detection scheme using the two difference voltage which can detect the sag around the zero crossing voltage is proposed.

Recently, various types of trains are being operated in the same railroad whose designated stop stations are not the same. In other words, each train does not stop at every station. This could cause the pass-through accidents in which a train passes a station where it is supposed to stop. Although the number of train accidents is on the decrease, this type of error is still an important problem to be resolved. It is true that the burdens of train drivers are growing because the number of high speed trains and non-stop stations is increasing in the current railway system. However, another major reason for this accident is that there is no prevention system for these errors in the current train control system although it is being constantly improved. The purpose of this study is to reinforce the train stop system with wireless communication equipment in order to decrease this type of accident and to maximize the safety of railway transportation.

DOI : 10.5207/JIEIE.2014.28.12.095
This paper proposes a coordinated control for an independent multi-phase transverse flux linear synchronous motor (IM-TFLSM) based on magnetic levitation. The stator structures of the IM-TFLSM are composed of a two set, which has independent three-phase windings and a double-sided air-gap as opposed to the conventional Y-connected three-phase linear motors. A suitable control algorithm is necessary to operate the applied linear machine. This study proposes a coordinated control algorithm for adjusting the mover air-gap and thrust force of the IM-TFLSM in order to maintain air-gap and phase shifted current control of the independent 3-phase modules. In addition, the principle of operation and its special structures are described in detail and the validity and effectiveness of the control algorithm is verified through multiple experimental results.

Together with housings, general buildings and industrial facilities, multi-purpose complexes are equipped with various and special equipment. They are often used by many unspecified people, which causes an increase in annual electricity consumption. Because of this, a great amount of money has been spent for electric charge, far more in excess of the budget, so a reasonable electricity rate needs to be estimated. In this study, we surveyed the power consumption, average power use, and annual electricity bill of multi-purpose complexes in the past five years. To see the general tendency of the survey, we conducted a statistical analysis with such parameters as average, maximum, and minimum values. Through regression analysis, we could see the trend of the survey in linear way. Based on the survey, we have developed an electric-rate calculation program to estimate the next year's budget on electricity.

Recently, Uninterruptible power supply(UPS) is spotlighted from concern about black out, due to reserve power problem caused by increased power consumption. When fault occurs on the grid, UPS system supplies power to loads instead of the grid. Also, it is an advantage of possible operation as Energy storage system(ESS). Bi-directional power control of AC/DC Pulse width modulation(PWM) converter is essential for grid-connected UPS system. And, mode transfer control has to be performed considering phase and dynamic characteristic under grid condition. In this paper, control of mode transfer and bi-directional power control of AC/DC PWM converter is proposed for UPS system. Also, it is verified by simulation and experimental results.

In case of power electronics, th power loss and EMI noise of IGBT is different depends on a adopting technology with the same power rating. To reduce the EMI noise, we could increase the resistance of gate. But in this case, the power loss of IGBT is increased, In this paper, we simulated the power loss of IGBT with the speed profile of elevator by the changing IGBT type, the voltage between gate and emitter, the resistance of gate in converter and inverter for elevator. To optimize the power electronics with the satisfied life time, It is necessary that we calculate the power loss and the rise of temperature in IGBT with the adopting technology type, the resistence of gate, the voltage between gate and emitter.

This paper describes the analysis of the effect on personnel computer in case of turning off power supply of main breaker in general electrical installation. In order to analyze the effect on personnel computer in case of turning off the power supply of main breaker, the switching impulse generator has been designed and fabricated which makes it possible to evaluate the effect on electrical product by switching impulse. The switching impulse tests were carried out for personnel computer according to applied voltage and number of switching impulse. As a consequence, switching impulse had not a significant influence on personnel computer in this study. The varistor of power input section functions as a protection of switching impulse as well as lightning impulse. The results will be used to related organization, and electrical product manufacturer, and residents.
