Harmonics Mitigation of Industrial Power System Using Passive Filters
For industrial power system operators, this provides a standard passive filter design approach, but the work is incremental as it applies existing methods without novel contributions.
This paper designs two passive filters to reduce current harmonics from nonlinear loads in industrial power systems, achieving reduced harmonics and improved power factor in simulations.
With the development of modern industrial technology a large number of non-linear loads are used in power system, which causes harmonic distortion in the power system. At the same time the power quality and safe operation becomes inferior. Therefore mitigation of harmonics is very necessary under the situation. This paper presents the design of two passive filters to reduce the current harmonics produced by nonlinear loads in industrial power system. Matlab /simulink software has been used for the simulation purpose. The results have been obtained with and without installation of filters and then it is observed that after installation of filters harmonics of the current are reduced and power factor is improved.
