  4. Abstract:
  5. This paper presents a newr control strategy for the shunt active filter in three-phase three-wire svstems with zero sequence voltages. An extended method based on instantaneous power theory in a rotating reference frame is developed for extracting the compensating signals for highlv/randomly varying loads. Since voltages at the point of common coupling contain low frequency interharmonics, conventional methods can not be used for dc voltage regulation. Therefore, a new method is introduced for this purpose. A three-phase electric arc furnace model is used to showT power quality improvement through reactive power and harmonic compensation by a shunt active fi'lter using the proposed method. Simulation results are plrovided to verify the system performance.©2004 IEEE
