چکیده
This paper presents a new and simple control strategy to determine reference compensation currents, under balanced and unbalanced source voltages which using the voltage source inverter for harmonic filtering of a three phase shunt active filter. The proposed control system is able to compensate the harmonics and reactive power of the non linear loads. The proposed approach is compared with a renowned shunt APF reference compensation strategy. The simulation of the system is done using MATLAB-SIMULINK and the results show that the proposed method is more effective than the existing one. In addition, the new approach demonstrates the substantial improvements in the filter performance during unbalanced supply and during load transients. The proposed control system is also very simple and robust. Moreover, it is very easy to implement this algorithm in a digital signal processor and testing results on an experimental shunt active power filter are presented to validate the proposed algorithm.
