Summary:The harmonic distortion of Bus Voltage in the power system is increasing due to wide use of nonlinear loads. Thus, it is important to analyze and evaluate the various harmonic problems in the power system and introduce the appropriate solution techniques. Use of Voltage source converters as Active Filters or Hybrid Filters are too expensive to be used by low end consumers in the distribution system for elimination of harmonics. Passive filtering has been preferred for harmonic compensation in distribution systems due to low cost, simplicity, reliability and control-less operation. But the conventional use of passive tuned filters suffer from many draw backs. This paper, firstly analyses the propagation of harmonic current and harmonic voltage in power system networks. A novel configuration of passive filter is designed and developed for mitigating bus voltage distortion. The merits of the introduced techniques were highlighted through a case study with simulation studies using MATLAB/SIMULINK. The feasibility of the proposed configuration of passive filter is verified from the experimental results.
