Algoritmo para detecção instantânea do ângulo de fase aplicado ao compensador série.

Abstract

This work proposes an algorithm to detect instantaneous phase angle based on sequence components. The method of weighted recursive least squares is used to estimate the components of positive and negative result. The phase angle is determined at each iteration, from the fundamental component of positive sequence. The operation of the algorithm is presented considering power quality conditions which are usual in the electric power system. Experimental tests under such conditions are presented and analyzed. he estimated value of the phase angle is applied to the series compensator control strategies to perform the voltage restoration and harmonics compensation. The results of the algorithm operation and the application to the compenstor are are presented and analyzed.
