An automated system for remote energy monitoring of mobile objects with electric drives

The impact of higher voltage and current harmonics on the operation of electrical systems

“…The implementation of variable-frequency electric drives to improve the energy efficiency of the technological processes at mining enterprises can result in a multiplied economic effect, provided that introduction and further operation of the electric drive systems are performed in a correct way [5]. Apart from the energy saving, the efficient management of the energy conversion and transmission processes through variable-frequency drive allows achieving the following results: improving actuators' performance through brand new solution for technological problems via process automation; reducing maintenance and repair costs for the processing equipment due to the more seamless transition processes and elimination of the surplus energy diffusion in the drive unit's parts and elements; increasing the operating life of electric motors and actuators [6].…”
