      Abstract

      Abstract. Nowadays most of factories use non-linear loads, such as VSD (Variable Speed Drive), rectifier, UPS system, computer, etc. They cause the harmonics and will be reduce the cost of power quality in the electric distribution system. Harmonics also influence the performance of the loads, which is used in that system.To reduce the harmonics in the system, we applied active filter by using a DSP card that connected with a PC. A sinusoidal waveform distorted with the harmonics will be processed, by using LabView 7 software, so the harmonics could be reduce or eliminated.By using DSP card, the harmonics which appear in the system, caused by of non-linear loads usage, can be reduced until 25th harmonics, so the cost of the power quality in that system will increased. In this case, we using a Sheldon Instrument’s DSP Card, SI-C33DSP-PCI, which is plugged by an analog I/O module, SI-MOD68xx, which is used for signal processing inside the computer. Furthermore, we must add a library for LabView 7, called QuVIEW, which is used to operate that DSP card.From the anlaysis that have been done, we can take a conclusion, the cost average of eliminated harmonics in distorted waveform is up tu 80. Which on pure triangle waveform, cost of THD decreased from 13.4376 become 3.12239
