Improving the Reliability of Power Supply Systems
Keywords:
recloser, sectioning, reliability of power supply, disconnection of consumers, reliability indicators, automatic reclosingAbstract
The article considers the possibility of improving the reliability of power supply systems. It has proposed to use sectioning devices - recloses for organizing ATS and AR, under voltage protection, overcurrent protection, protection against single-phase earth faults, and connection of new consumers. The level of reliability and quality of power supply of the distribution network assessed, which is carried out according to the indicative indicators SAIFI, SAIDI, RNRE and ARAE, which characterize, respectively, the number and duration of outages in the network for the period under review, the relative efficiency of reconstruction and the average efficiency of the use of reclosers.
