Description
Summary:The aim of this work is to provide both utility and customer planning engineers a methodology for aiding them to achieve compatibility between industrial processes requirements and the quality of the electrical supply, taking into account the influence of voltage sag on the latter one. By applying this approach, new indices for both supply system and load buses can be drawn. They can be used by end-users planning engineers to choose the best location in the supply system, where new sensitive load consumers are to be connected. The paper also presents an example, based on a real case, which illustrates the applicability of such a methodology.
