THE INVOLVEMENT OF INFORMATION TECHNOLOGY IN THE OPTIMAL FUNCTIONING OF ELECTRIC DRIVE SYSTEMS

The implementation of sustainable development in Romania and the abrupt increase of prices for fussil fuels have imposed more serious activies for the examination of the energy consumption in different industrial sectors. Here, the asynchronous electric motors represent the main loads; therefore the energy consumption in electrical drives has to be careffuly watched. The achievement of various procedures to improve energy efficiency, compulsory imposes an energy balance who aims to illustrate the existent profile of energy consumption . The study presents an industry case study about estimation of operating systems functioning that use variable speed motors, highlighting the necessity and appropriateness of using informatic instruments that provide calculations needed to elaborate energy balance and by that, to determine the measures to increase energetic efficiency.energy efficiency, electric drive, energy balance, power factor, informatic instruments
