Electronics Nuclear engineering In recent years, power electronics equipments have been widely used in industry. These types of load create an intolerable power quality issues which is harmonic distortion at the main power. In order to overcome this problem, active power filtering with various topologies has been presented in previous studies. This project proposes a single-phase hybrid active power filtering using multilevel inverter topology. The proposed topology interconnects the passive filter with active power filter through point of common coupling (PCC). The topology chosen for active power filtering is the modular structured multilevel inverter which offers wide range of advantages over basic configuration of active power filter. The hybrid topology also provides advantages over non-hybrid active filter which is able to compensate both higher and lower order of harmonics. This project also proposes a nonlinear control scheme which is unified constant-frequency integration. This control scheme is able to avoid the complex calculation of current reference that is often used in most proposed hysteresis current control. Its simpler configuration utilizes one-cycle control theory which integrates the input voltage cycle-by-cycle which results in more precise current compensation. This report describes the highpass filter design, multilevel inverter circuit topology and its control scheme. The system is verified using MATLAB/Simulink simulation package that offers wide range of application in power system. Comparison analysis shows the performance evaluation of each compensation circuit from basic H-bridge inverter circuit to nonhybrid multilevel inverter circuit and lastly the proposed hybrid configuration. Simulation results shows that the total harmonic distortion of the source current have been reduce abruptly from 124.54% to 6.61% after compensation using the proposed hybrid configuration. 2011-06 Thesis http://eprints.utm.my/id/eprint/32816/ http://eprints.utm.my/id/eprint/32816/5/NurHudaRamlanMFKE2011.pdf application/pdf en public masters Universiti Teknologi Malaysia, Faculty of Electrical Engineering Faculty of Electrical Engineering |
