Localização e operação cooperativa de filtros ativos de potência em redes de distribuição.

Abstract

This work has as objective the study through simulations and practical implementation, of optimum localization techniques and cooperative control for power compensators and in distribution networks. The study considers the limits of total harmonic distortion and individual harmonic distortion, defined in the ieee-519 standard. The active power filter, in the "Shunt" configuration, operating with voltage sensing control, was selected as compensator for the evaluated scenarios. By means of simulations, a simplified algorithm of optimal location was developed, which determines a location solution considering the following criteria: i) less effort of filters, ii) amount of compensators to be installed in the distribution network, and iii) . The solution generated by the simplified location algorithm determines the optimum coupling point of the active filters available, together with the harmonic current level considered in the optimization problem, which each filter must inject into the network in order to satisfy the criteria of the standard IEEE-519. Analyzes carried out confirm the effectiveness of the optimal localization technique by the simplified algorithm, as well as the cooperative operation of the filters, in which the control action derives from the optimal localization algorithm. In these analyzes, it was observed whether the optimal points and calculated compensation currents were valid, emphasizing that for the data to be valid the results must satisfy the norm
