Power Quality Improvement using Shunt Active Power Filter
Nowadays, usage of non linear loads in power system is increasing. For example, UPS, inverters, converters, etc. These loads make the supply current non sinusoidal and distorted form, which is called harmonics. At this time Active power filters have been developed to improve power quality. In this Paper, a Shunt Active Power Filter SAPF control scheme has proposed to eliminate the current harmonics and improve the power quality. The shunt active power filter controlled by using the different controllers such as PI, PID, Fuzzy logic, Pq Theory and hysteresis controller . In our proposed system, PI controller is used to reduce the harmonics current using the shunt active power filter. And both current THD results are compared, with and without use of filter and then shown how filters can reduce THD and is most suitable to control the shunt active power filter in term of total harmonic reduction THD . MATLAB SIMULINK power system toolbox is used to simulate the proposed system.
