Abstract

This paper presents a new Walsh function(WF) based method for the evaluation of reactive power (RP) component from the instantaneous power signal in sinusoidal conditions. Proposed method simplifies the multiplication procedure to evaluate the reactive components from instantaneous power signal. The advantages of the proposed method have been verified by the simulation studies. One of these advantages is that in contrast to the known existing methods which involve phase shift operation of the input signal, the proposed technique does not require the time delay of the current signal to the pi/2 with respect to the voltage signal. Another advantage is related to the computational saving properties of the proposed approach coming from use of the Walsh Transform (WT) based signal processing method. Validity and effectiveness of the suggested method for evaluation of the RP components of the electrical power have been tested by use of a simulation tool developed on the base of Matlab .
