Reactive Power Compensation and Harmonic Filter using SAPF in MATLAB

This project work presents a shunt active power filter method for harmonic filtration and reactive power compensation. Due to wide use of non-linear single phase power electronic devices in low voltage side has increased harmonic pollution in the power system to the larger extent. The presence of harmonics in electrical systems means that current and voltage are distorted and deviate from sinusoidal waveforms which can cause many different problems in the electrical system and sometimes also leads to the faults in the system. Reactive power makes the generation and distribution of electrical power very inefficient so this is very important to neglect harmonics and reactive power from the system. Improving power quality has become the biggest challenge for electrical engineers. A shunt active power filter was modeled in MATLAB/SIMULINK to reduce harmonics and reactive power. Simulation results are presented to demonstrate performance of shunt active power filter during presence of non-linear load.
