    Abstract

    Due to the high competitiveness of the power market along with cost reduction of new technologies, currently there exists a worldwide tendency for using novel electric power generation resources. In this way, according to technical and economic analyses, the insertion of such generation can be suitable not only within transmission networks, but also at medium and low voltage levels, within the distribution networks. However, this Distributed Generation (DG) makes some parts of the feeder lose its radiality. It has direct influence on the protective devices coordination installed on the feeder. DG placed on the distribution feeders affects the voltage profile and shortcircuit current levels, system stability, and may result in islanding of some network areas. Thus, an expert computational system for performing protection projects for overhead distribution feeders that present -or not- distributed generation (DG) is proposed. In order to assess the computational system efficiency a real-life distribution feeder is used.
