The impact of selected variants of remote control on power supply reliability indexes of distribution networks

Abstract

Ensuring reliability and continuity of energy supply is the main goal of local governments and distribution companies. The continuity of energy supply means capability of a power grid to supply agreed amount of energy, of specific quality, without power cuts. The expectations concerning the quality of supplied energy and ensuring its continuity are constantly growing, and any power cuts have significant impact on comfort of life and manufacturing and service sector. To increase reliability of energy supply and improve condition of a power grid in the distribution companies, the works are conducted to increase power supply reliability indexes.The main goal of this publication is to present a problem of discontinuity of energy supply and actions aiming at improvement of power supply reliability indexes. An analysis of discontinuity of energy supply presented in the article is based on data obtained from a selected department of a distribution company. Based on actual data, the impact of location of remote-controlled controllers on the value of SAIDI and SAIFI was presented. Four variants of remote control on the sequence of a medium-voltage cable line were analysed.
