| Summary: | 碩士 === 國立勤益科技大學 === 電機工程系 === 98 === THE use of nonlinear loads and power switching devices is increasing because of their high efficiency and convenience for control. In the meantime, they induce harmonic pollution problems. In order to reduce the harmonic pollution problems and ensure the quality of the power supply, this paper used the direct determination approach of a bus impedance matrix and associated with called the harmonic current emission level index (CELI) for reducing harmonic voltage distortion in distribution systems. According to the CELI approach installs the passive harmonic filter (PHF) at the strategic bus for reducing the effect of harmonic voltage distortion .The approach is effective and powerful, that can effectively control harmonic current in distribution system. The proposed approach was tested on an 18-bus radial distribution system. Results obtained that show the approach can correctly found the location of install the PHF in distribution system.
