      Condition Knowledge gained on courses that form the core of Power engineering department, Power converter and drives and Power systems on School of Electrical Engineering.
      The goal Students are introduced with methods of considering Electrical drives as a consumer of electrical energy. Options review for electrical drive energy efficiency increase in the design stage, during commissioning and by optimization of the process driven by the drive in consideration. Methods of analyses of the influence the drive has on the supply grid and means for mitigation of negative effects
      The outcome The ability to analyze the electrical drive from the electrical energy consumer point of view, and aspects of the supply grid connection. Preparation and training for the analyses of energy efficiency of the electrical drive and the driven technological process as a whole.
      Contents of lectures Active, reactive and distortion power, power and displacement factor, analysis and measurement methods in electrical drives (EMP). Energy Efficiency (EE) of process. Speed control. Application of optimal control strategies. Rectifiers for multi-motor drives. The influence of unbalances and voltage dips to the EMP. Reactive power compensation and harmonics mitigation. Control of power converters
      Contents of exercises Demonstration of energy savings potential in pump or fan applications, in bulk material transport, with measurements. Active, reactive and distortion power measurement in controlled electrical drive (EMP) with DC and induction motors. Regeneration of energy in EMP, experimental verification. Harmonic analysis of EMP supply current. Demonstration of influence of controlled EMP to grid.
