Abstract
Efficiency improvement of modern production is associated with uninterrupted power supply to consumers. Power supply reliability to consumers is ensured by reliable operation of power lines. The number of outages depends on their condition and operation quality. An increase in the number of outages affects the further degradation of power line state, significantly reducing the resource of lines and equipment; and it takes a lot of time to find faults and eliminate them. Monitoring of power outages in overhead power lines will reduce the time of emergency elimination.1
Highlights
The need to implement power outage monitoring was predetermined by the analysis of the condition and fault rate of 10 kV radial overhead lines in the Oryol region
The cross-section of this wire is two steps lower than currently recommended for trunk sections under the condition of providing mechanical strength. This fact alone is one of the reasons for the increased number of line faults. Another reason is related to the fact that the main part of the 10 kV overhead lines (60%) was built before 1990 and their service life has already exceeded the standards
If in 2014 emergency outages amounted 67.4% of the number of planned outages, in 2017 they made up 81.1%
Summary
The need to implement power outage monitoring was predetermined by the analysis of the condition and fault rate of 10 kV radial overhead lines in the Oryol region. Analysis of the condition and fault rate of overhead lines in the Oryol region includes: analysis of the length of lines, technical condition of 10 kV overhead lines, indicators and main causes of line breakdowns. These indicators characterize the dynamics of the state of overhead lines and make it possible to forecast their faults [1, 2]. Implementation of power outage monitoring in 10 kV overhead lines will allow attending personnel to eliminate faults as soon as possible and to prevent them [3,4,5,6]
