Adaptive Generalized Delayed Signal Cancellation Method for Phase-Sequence Estimation

The aim of this paper is to investigate the implementation of an adaptive generalized delayed signal cancellation (DSC) method for estimation of phase-sequence components. The proposed approach overcomes the intrinsic problems of the digital implementation of the classical DSC algorithm due to non-ideal selection of the sampling frequency and variations in the nominal system frequency. The derived algorithm is extended for estimation of harmonic components in the measured signal. The effectiveness of the proposed estimation method is validated through experimental results
