The article analyzes efficiency of variable frequency drive (VFD) in the conditions of diamond mining. The aim of the study is to formulate and formalize the problems of introducing and operating a variable frequency drive in diamond mining with a view to further development and implementation of methodological recommendations on VFD efficiency improvement. Achieving this goal requires studying and analyzing VFD operation in various process installations in diamond mines. The use of VFD to increase energy efficiency of industrial processes with the appropriate approach to implementation and subsequent operation of electric drive system can produce multiplicative economic impact, which conditions wide application of VFD in mining. The analysis of VFD operation in process installations of dredge, processing plant and underground mine of ALROSA reveals both positive and negative effects. For example, with the use of VFD on a pulp pump at the processing plant, electric energy consumption was reduced together with the cut down in maintenance and repair costs of the pump and pipelines due to smooth transition processes and elimination of hydraulic shocks. The negative experience VFD introduction and operation is the replacement of frequency converters of dredge actuators in 2017. The new frequency converters installed on the dredge nasal shunting engines lacked capability to provide torque control (vector control), which was essential. These examples confirm that selection of VFD system should take into account many factors that will ensure its effective introduction and use on a specific process installation. In this regard, the authors propose solutions to the above problems through the development and implementation of scientifically and practically sound methodological recommendations on selection and preventive diagnostics of VFD, which should be a framework of the intelligent database for introduction and operation of variable frequency drives in diamond driving.
