Design of shunt hybrid active power filter for compensating harmonic currents and reactive power

Abstract

For the past two decades, tremendous advancements have been achieved in the electricity industry. The usage of non-linear loads in the daily life has affected the power quality of the system and caused the presence of harmonics. To compensate the harmonic currents and reactive power in the system, the design of shunt hybrid active power filter has been proposed in this research. The design of the filter has included several control systems of instantaneous active and reactive power (p-q) theory and PI controller to investigate the performance of the filter. The robustness of the designed hybrid power filter has also been benchmarked with the other filter topologies available in literature. The hybrid power filter will combine passive power filter and active power filter configurated in shunt connection. The result of this research showed that the total harmonic distortion analyzed is below than 5% according to IEEE-519 standard requirements and reactive power is compensated proved by the increase in power factor. The shunt hybrid active power filter is designed, and simulation result is analyzed by using MATLAB-Simulink environment.

Study of the performance of fault-tolerant multi-level inverter included in shunt active power filter

“…To achieve these advantages, some scientists are interested to the application of the SAPF in different situations in the grid network, Ouchen et al [5] applied the predictive direct power control for the SAPF, in another study, they incorporated the fuzzy logic technique in the SAPF associated with photovoltaic system to improve the results of the predictive direct power control [6], Dash et al [7] included the harmonic mitigation for the SAPF to reduce the current [8] improved the performance of the SAPF by applying the fractional proportional integral controller. There are other studies that have contributed to the application of the filter techniques that help to reduce the harmonics, among these Saleh et al [9] conducted a comparative study between the nearest level control and the selective harmonic elimination for multi-level inverters, Alhamrouni et al [10] focused on the designing of a topology that contributes in compensating both the reactive power and harmonic currents. Therefore, the SAPF is considered as an ideal resistant to the non-linear load [11].…”
