Abstract :
This paper introduces a new adaptive notch filtering (ANF) method for detection of symmetrical components. This is a powerful tool for synchronization of converter-interfaced distributed generation (DG) systems. The technique is simple and offers high degree of immunity and insensitivity to power system disturbances, harmonics and other types of pollutions that exist in the grid signal. The proposed technique is capable of decomposing three-phase quantities into symmetrical components and tracking the frequency and amplitude variations. Theoretical analysis is presented and the performance of the method is evaluated through simulation.
