摘要：

Among a series of parameters, power quality studies are concerned with voltage unbalances, which represent the voltage magnitude and phase deviation from nominal values. In order to determine the influence of the network's parameters on voltage unbalances, and to provide exact Solutions to reduce or even eliminate them, the present study develops and presents two methods. First. a sensitivity analysis is used to determine the influence of each parameter. and then analytical solutions are developed in order to provide the changes needed for correction. The quantification index considered is the symmetrical components method. (C) 2009 Elsevier B.V. All rights reserved.
