| Abstract | ||
| Abstract: T h is paper presents a new control strategy to improve the performance of the shunt active power filter (SAPF) in three-phase four-wire system when operating under an unbalanced system .The compensation algorithm is based on pqr theory. This scheme requires the service of a phased-locked loop (PLL) to make the system insensitive to the distortions that are generally present in the utility voltages. A three dimensional hysteresis current controller is used to track the compensated current references. Computer simulation results are given to illustrate the system performances based on the proposed control strategy. | ||
