Harmonic Compensation using Shunt Active Power Filter in Power System using MATLAB

Neha Kumari; Isha Awashthi

Abstract: With the increased use of non linear load, the power quality is degrading. Thus, it is important to invent such methods and devices which will improve the power quality. Shunt active power filter is one such device. Shunt active power filter improve power quality very efficiently. The paper uses pi controller, hysteresis controller low pass filter, dc link capacitor.The controller for the generating reference current is unity template theory, this theory is very easy to implement and does not make use of heavy mathematical equations. The shunt active filter is placed in parallel to loads. Three phase three wire system is used. Mat lab/ Simulink method is used to show result. The target of paper is to reduce total harmonic distortion in the source current. This paper successfully lowers the THD within IEEE norms and satisfactorily works to compensate harmonic.

Keywords: shunt active power filter, unity template method, pi controller, reference current generator, total harmonic distortion, pi controller, hysteresis band current controller
