Localização, dimensionamento e controle de compensadores ativos em redes de distribuição.

Abstract

This paper proposes a method for allocating and sizing multiple current-constrained active power line conditioners (APLCs) in power distribution networks. The location and size of the APLCs are optimal with respect to the power distribution topology regardless the load consumption pro le as long as the distributed power demand does not exceed the power rating at each one of the points of common coupling (PCC). The optimization problem is stated in terms of the total harmonic distortion (THD) and the individual harmonic distortion (IHD) observed at each PCC and takes into account constrains like minimum line losses, minimum compensation current and minimum quantity of APLC units. The constraints aims at satisfying speci c power quality requirements like the ones prescribed in IEEE 519-1992. Simulation results are presented to demonstrate the feasibility of the proposed approach as well as to emphasize its distinct features in comparison with similar and well known methods. The stability analysis ensured that the optimal points are stable fot the controlled current source based on voltage detection regardeless the power elements variation. The APLCs control operates to damp THD and IHD constrains cooperating with each other without any communication. All studies, locatication, sizing and control, were tested in a real time plataform and proved to be feasiable.
