 ABSTRACT

  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 is applied in this paper as a reference for domestic standards on THD-V limits management.In recent years,according to integration of KSC standards into IEC,UPS standards are being revised as KSC IEC 62040,but there are still no regulations for THD-V and THD-I about UPS causing confusions in some aspects.Accordingly,in the KSC IEC management standard stobe amended which are related to UPS,I consider the introduction of the integrated regulatory limits on THD-V and THD-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.
 1. Three-phase and single-phase inverter of the UPS system being measured THD-I in the regulation of the country in accordance with the regulation within the KSC 4310 was confirmed that, THD-V is a provision of foreign IEEE Std. 519. Therefore, future established at the time of involving KSC IEC management standards associated with UPS, KSC 4310 and IEEE Std. 519 is possible to apply the integration.
 2. UPS also occur in both the voltage and current harmonics occurs mainly in lower-order active filters which were to enhance the harmonic reduction can be effective.
