Sistema elétrico de propulsão para barcos de pequeno porte empregando baterias e energia solar-INEP-UFSC-INSTITUTO DE ELETRÔNICA DE POTÊNCIA-BRASIL


O projeto trata do desenvolvimento de um sistema elétrico de propulsão e de captação de energia solar fotovoltaica para um veículo de transporte marítimo de pequeno porte. Emprega carregadores de bateria (a partir da rede elétrica e de painéis fotovoltaicos), inversor de tensão trifásico e motor. O sistema eletrônico desenvolvido possibilita substituir o sistema de propulsão à combustão em embarcações de pequeno porte. Estas embarcações, projetadas especificamente para o sistema de propulsão elétrica, poderão ser utilizadas para inspeção de lagos de barragens de hidrelétricas. Também poderão ser utilizadas para: - Inspeção e fiscalização em áreas litorâneas da costa brasileira; - Visitação turística em áreas fluviais ou marítimas de proteção ambiental.

A Study of UPS System Using Integrated Source Transfer Switch Method Yong-UkKim Department of Electrical Engineering Graduate School of Industry Pukyong National University


Abstract - Single UPS operation of a plurality of such parallel d related research is going.UPS voltage/constant-frequency supply capacity of STS and multiple UPS parallel operation of the problems caused
due to the combination of transfer function of an uninterruptible power neutrali zing SYSTEM propose a way of switching from traditional asynchronous state on the benefits and Radish only transfer the problems caused by five manual operation of an asynchronous operation and SCR switching behavior is studied.

A Study on Management Standards of Total Harmonics Distortion(THD)measured from UPS - Jeong,Unho Department of Electrical and ElectronicEngineering Graduate School,Dongshin University


The purpose of this paper is to describe UPS(Uninterruptible Power Supply) in a comprehensive measure THD(Total Harmonic Distortion) and compared with domestic and international management standards in harmonics, harmonics reduction measures by analyzing the appropriate UPS technology. Harmonics generated by the UPS. measurements of national standards was confirmed appropriate, UPS comprehensive harmonic currents measured range THD-I limits for national standards, the reference by KSC 4310, THD-V for domestic not based on the site was confirmed. Therefore,The IEEE(Institute of   Electrical and Electronics Engineers)Std.519 i applied in this paper as a reference for domestic standards on THD-V limits management.In recent years,according to integration of KSC standards in to IEC,UPS standards are being revised as KSC IEC 62040,but there are still no regulations for THD-V and THD-Iabout UPS causing confusions in some aspects.Accordingly,in the KSC IEC management standards to be amended which are related to UPS,I consider the introduction of the integrated regulatory limits on THD-V andTHD-I which are currently mixed to be very urgent. Therefore In this paper, we measured the THD-I and THD-V for UPS domestic and international management standards and harmonic comparison and analysis results were as follows.

A Study on the Heat Flow Inside UPS according to the Outside Temperature -Dong – Min Kim Department of Mechanical Engineering, The Graduate School Konyang University Nonsan Chungnam Korea



Dong – Min Kim Department of Mechanical Engineering, The Graduate School Konyang University Nonsan Chungnam Korea

 UPS is an electrical apparatus that provides emergency power to a load when the input power source, typically mains power, fails. When installing UPS in outdoors (a road near or mountain, etc..), it is also possible many problems according to the outdoor environment. And it is possible generate condensation by a temperature difference The purpose of this study was to predict the inner temperature of UPS and to prevent dew condensation in UPS by simulating the heat flow using ANSYS. So in this study, The inner heat flow simulations for UPS were conducted by the Computation Fluid Dynamics Analysis, ANSYS, during the active state of UPS. Compared with Air temperature, Relative humidity, Inner temperature of UPS to be found that condensation is occurring. It’s can be improved by ventilation or insulation effectively inside UPS according to this simulation result.
