| Abstract |
This paper investigates issues related to practical
implementation of the Delayed Signal Cancellation (DSC)
method for on-line detection of positive and negative sequence
components of three-phase quantities. The detection error due
to non-ideal sampling frequency is calculated. Furthermore,
the effect of the DSC method on estimation when harmonic
components are present in the input signal is analyzed. It is
shown how harmonics transfer through the DSC and how a nonideal
sampling frequency affects the estimation of the harmonics.
Experimental verification of the analytical results is presented. |
