Investigation of Electric Power Processes During Mining Excavator Operation

The results of the analysis and experimental study of power consumption during the operation of an electric excavator in a quarry are proposed. The features of accounting for electricity consumption in the mechatronic complex with a complex power consumption mode, including energy recovery, are considered. The costs of direct and recuperated energy were experimentally determined at various time intervals at the career excavator EKG-20 in the operation mode. The specific power consumption of the excavator, the ratio between consumed and recovered energy were determined, and also the estimate of the part of the recovered energy used by the electric equipment of the excavator's own needs was obtained.
