Description
Summary:Power Distribution system is polluted by harmonic and reactive power disturbances due to the large usages of non-linear loads (Computers, Laser printers, SMPS, Rectifier etc.). Harmonics cause a number of undesirable effects like heating, equipment damage and Electromagnetic Interference effects in the power system. Active power filter (APF) or Active power line conditioner (APLC) is a suitable solution to compensate for the adverse effects of harmonics and reactive power simultaneously. Synchronous reference frame (SRF) theory is adopted for extracting fundamental components. In this paper, a comparative study of the performances of two current control strategies namely the hysteresis current controller (HCC) and adaptive hysteresis current controller (AHCC) is carried out and superior features of AHCC are established. Results of simulation studies on the performances of HCC and AHCC are included to demonstrate the effectiveness of using adaptive hysteresis band.
