Power Quality Enhancement Using Shunt Active Power Filter with Vienna Rectifier

Abstract

Nowadays, there are a large number of electrical components in domestic, commercial, and industrial applications. The demand for power conversion from one stage to another is necessary for obtaining a proper result in distribution systems. But, it creates power quality problems like voltage spike, voltage dip, swell, harmonics, over voltages, under voltages noise, etc. Harmonics is main representation of power problem in industrial and commercial venues. Conventionally, the passive filters are used to reduce the harmonics content. But, it has some disadvantages like resonance problems and large size, tuning of particular frequency and particular reactive power compensation. To solve the abovementioned problems, active filters are dedicated used to reduce the harmonics content in the power distribution system. In this, the proposed model, three-phase Vienna rectifier is performed to serve as shunt active power filter (SAPF) for reactive power compensation. Fewer switching devices, low circuit losses, and higher power density are the advantages of VIENNA rectifier when compared to PWM rectifier topology. By using MATLAB software, the usefulness and feasibility of the proposed model is tested and certified. Results taken from simulations circuit show that the new proposed model is more effective than other conventional for reducing the harmonic currents filtering action. The three-phase Vienna rectifier-based SAPF can attain and maintain the total harmonic distortion of info source current inside the breaking point recognized by the IEEE-519 Standard.
