Analysis of a Quarry Mobile Diesel Generator Station During the Moving of an Excavator

Abstract

The results of calculation and analysis of an autonomous quarry station with a voltage of 6.3 kV for powering excavators and drilling rigs during movement are considered. Structurally, the station is made in the form of a removable module of a closed design, which is installed in place of the standard body of the base truck. The module has two compartments and a transition pad. A diesel engine and its support systems (fuel, air, cooling, lubricating, and starting) are installed in the front compartment. A transformer and a high-voltage cabinet are located in the rear compartment. The system of electrical equipment provides all types of protection to ensure the safe operation of the station. The results of station power calculations for the movement of various excavators are presented. To control the mobile station, modern means of automation and remote control were used. A specialized computer provides remote start-up and shutdown of the unit, engine support, adjusting the parameters of the regulators, measuring the parameters of the generated electricity, recording processes during the run, generating a history file, remote monitoring, including using the Internet. The control of the electric equipment of the excavator during the movement provides for speed limits when moving uphill or downhill in accordance with the energy capabilities of the diesel generator station.
