Possibility of application hybrid solutions for improving SAIDI coefficient in medium voltage lines

Abstract

The purpose of this work is to analyze the indicator of the duration of interruptions in the supply of electricity SAIDI (System Average Interupption Duration Index) given by power distribution operators (DSOs). The topic is so important for the Polish economy that it can be treated as a social problem that can not only reduce the quality of life, but also the economic development of small towns and villages where power outages are much longer than in cities. However, at the same time investment activities aimed at improving the quality of electricity distribution in Poland represent a very high chance for the development of new innovative technologies. The article presents not only related aspects with medium voltage network automation, but also due to their technical and economic capabilities, modern devices. The key in the article is the effective solution to the problem of reliability in Poland and the presentation of selected directions of investment.
