The operational availability of mining shovels is the focus of this paper. The hypothesis is that energy quality is responsible for the frequent shutdowns of the shovels. Previous engineering studies have highlighted a large presence of harmonics and reactive power in the mine loop electric system. A common solution proposed was to use a combination of active filters, larger mobile substations, shorter...
This paper presents a solution to energy quality problems in an open pit mine distribution system. Specifically, mine shovel operation is frequently disrupted by energy quality issues. A number of alternative approaches to deal with this problem include: the use of reactive power compensator technologies (i.e. passive filters; electronically switched capacitor banks and static VAR compensators), imposing...
