Power System Harmonic Reduction Using Single Tuned Passive Filter

One of the destructive effects of nonlinear loads is producing harmonics that makes a lot of problems in power systems. Varieties of methods for reducing harmonic have been suggested in different articles. For decreasing the harmonic produced by the rectifier that is one of the most important sources in producing harmonics in power systems، different types of electrical filter have been used. In this article in addition to describing the act of single tuned passive filters we completely defined the essential formulas for this type of filter and with the help of simulations in MATLAB، the impact of passive filter in decreasing the current harmonics and improving the power quality has been evaluated.
