Abstract
This paper proposes a new positive and negative sequence detector for fast system´s protection. The proposed detector scheme uses Savitzky-Golay filters, to get a filtered version of the signals´ time derivatives. A comparison, using simulations and experimental tests, of the proposed detector and of a second order generalized integrator (SOGI) based detector, shows the advantages of the former.
