    The goal Options to increase energy efficiency of electrical drive at each particular level: selection of motor and other components within the drive in the design stage, drive parameters tuning during the commissioning, energy efficient motor control and energy optimal control of the process driven by the drive in consideration. Electrical drive impact to supply network: negative effects elimination.
    The outcome The ability to analyze the electrical drive from the electrical energy consumer point of view and aspects of the supply network connection. Preparation and training for the analyses of energy efficiency of the electrical drive and the driven technological process as a whole with the use of modern technical, technological and software tools.
    Contents of lectures Energy optimal control of induction motor. Electrical drive as a consumer: harmonics, active, reactive and distortion power, power and displacement factor. Passive and active filters. Active rectifier. Energy efficiencient control of process with electrical drive of rewinder, belt conveyors and pump. Energy efficient electrical drive with permanent magnet synchronous motor. Energy management.
    Contents of exercises Demonstration of energy saving potentials in pump or fan applications and in material transport application of drives. Measurement of active, reactive and distortion power in electrical drives with DC and induction motors, harmonic analysis of supply current, demonstration of drive impact to supply network. Regeneration of energy in electrical drives, experimental verification of energy savings.
