Abstract
Power system of the Kemerovo region is unique in terms of the number of hazardous production facilities (coal mines, coal pit). To ensure trouble-free operation of hazardous production facilities and the normal operation of other consumers, it is necessary to ensure reliable operation of regional electrical grid networks. Based on reports on technological disruptions in electric networks of the Kemerovo region in 2015, performed analysis of accidents in 6-110 kV electric networks of Kuzbass power system. The statistics of the technological disruptions in terms of voltage classes, damaged elements, causes of occurrence, time to recovery and the number of outages of household consumer, are given. Conclusions were drawn about the high level of accident rate in 6-10 kV electrical network.
Highlights
The Kemerovo region is a large industrial region and plays an important role in the economy of Siberia, but of the whole Russia
The study analyzed more than 5000 technological disruptions (TD) that occurred in 6-110 kV electric grids of the power system of the Kemerovo Region
About half of all TD occurred in the period from May to August
Summary
The Kemerovo region is a large industrial region and plays an important role in the economy of Siberia, but of the whole Russia. The basic industries of the region are the coal industry and metallurgy, as well as the chemical industry, power engineering and machine-building branch. In the Kemerovo region located a lot of large industrial enterprises, some of which are hazardous production facilities. For trouble-free operation of such consumers it is important to ensure reliable operation of their external power supply system and the power system of the Kemerovo region as a whole
