Research of Loadings Character in Electrical Networks of Open-Casts Mining

Abstract

Calculation of loadings and losses in electrical networks of open-casts is bound to the difficulties caused by irregularity of individual production schedules of rope shovels – the main and most power-intensive consumers. The computational method according to load charts is presented. It allows to consider irregularity of loading manifestation during an shovelling cycle that significantly increases accuracy of calculations of losses in net-works in comparison with calculation for mean squared current.
