A Literature Review and Industrial Survey on Active Power Filter

 

Power quality problem in distribution system is major concern due to increasing use of nonlinear load like adjustable speed drive (ASD), furnaces, computer, fluorescent light, battery chargers etc. this nonlinear loads are sources of harmonic distortion in voltage or current. Due to this distorted voltage a power quality issue like sag ,swell, harmonics, flicker is occur in the power. To mitigate this harmonic content from the ac power supply voltage a traditional passive filter is used but there are some limitation and drawbacks of passive filter. So to overcome this limitation and draw backs of passive filter a power electronics switch based active filter is used with suitable algorithm. An active filter is also known as active power line conditioner, instantaneous reactive power compensator, active power filters
