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.

Study of Control Strategies for Shunt Active Power Filter for Harmonics Suppression

Excessive use of nonlinear and time varying devices results in harmonic currents in the secondary distribution system. The suppression of harmonics is a dominant issue and one of the practical ways to compensate harmonics is shunt active power filter (SAPF). The core part of the SAPF is control techniques used for reference current generation. This paper presents a comprehensive study of three control strategies namely instantaneous reactive power (p – q) theory, synchronous reference frame (SRF) theory and instantaneous active and reactive current (id - iq) component method for SAPF in a three phase three wire distribution system. These three control methods aims to compensate harmonics, reactive power and load unbalance under sinusoidal balanced supply voltage conditions. Simulation results present a relative investigation of three control techniques based on current THD and load unbalance.
