Advanced technology to conserve resources and energy efficiency for complex automation of electric industrial machinery oil and gas industry

Aspects of frequency controlled drive use in automation of the energy saving technical process are reviewed. Oscillograms of automatic switch of the motor power supply from the inverter to the main supply and vice versa are shown.
Materials and methods
Implementation experience. Processing of the experimental studies results.
Results
Variable frequency drives with asynchronous and synchronous motors have been introduced in the automated control systems of JSC "Transneft" technological equipment
Сonclusions
The use of a frequency-controlledautomation not only saves energy, but also allows to shift to new resource saving technologies.
