A REVIEW OF HARMONIC ANALYSIS AND MITIGATION TECHNIQUES USING FILTERS

Nonlinear loads draw non sinusoidal current and voltage from the utility.These nonsinusoidal current and voltages created due to nonlinear loads are called harmonics.The harmonic voltages and current disturbs the system back and creates big power quality problem.Therefore in order to mitigate harmonic problems different mechanisms are used.Here as introduction different power quality problems, harmonics and their mitigation techniques/filters are presented and discussed.Between the different ways to minimize/eliminate harmonics active power filters are most prominent one.
