摘要:At the current stage, in electrical distribution systems from Republic of Moldova, take place a significant number of unplanned disconnections, which considerably reduce quality and continuity of the distribution process and power supply. Knowing the evolution of these disconnection for long periods, offers the possibility to elaborate a credible prognosis, which helps to establish solutions to ensure the reliability of these systems. In this work, is presented a study regarding evolution of unplanned disconnections from electrical republican distribution systems and the results of this study allow developing the insurance mechanism of the reliability indicators and quality of power supply, forRepublic of Moldova.
