Efficiency of Decentralized Sectionalizing System for Overhead Distribution Networks

Abstract

The solution of urgent problems in 35 kV networks, which is sectionalizing of overhead distribution networks of medium voltage in order to increase the reliability of consumers power supply, is considered in this paper. The share of 35 kV networks is high, and almost half of distribution network supply centers are 35/10 kV substations. The length of 35 kV overhead lines in Rosseti, JSC alone is 115.286 km. For oil and gas production enterprises, as well as for a number of industrial enterprises, 35 kV class remains the main one in the power supply system. The purpose of this work is to analyze the efficiency of using SMART 35 kV reclosers in 35 kV networks. To analyze the efficiency of using reclosers in this paper, we assessed the reliability of consumers power supply in medium voltage class networks. The main indicator of power supply reliability is the amount of power undersupply to consumers.
