Department of Energy Technology Engineering

The course aims to equip students with the necessary knowledge to understand the electric drive systems, as one of the major electricity uses fields. The aim is to gain knowledge about the structure, operation, control, selection criteria and use of automated or non-electric drive systems in power plants, systems and facilities, as well as their contribution to energy saving.

Course Description

Theory: The use of electricity in motion and the requirements of the drive systems. Structure of electric drive systems. The system electric motor, drive transmission mechanism work machine (load). Torque, stability, transient states. Brief reference to the functional behavior and the electric motor control authorities. Classification. Motivational systems without electronic devices control. the driving systems with electronic power converters. DC motor system with inverter controlled AC or DC electronic voltage regulators. Systems of three phase induction motors with electronic converters control the alternating voltage or kyklometatropeis or frequency voltage source converters or power or converters control with slip power recovery. Systems modern AC motors kyklometatropeis, systems testing bonding modern engines forced or natural transition. Motivational systems with other types of electronically controlled engines. Applications of programmable controllers in motion. Mathematical analysis, permanent and transient behavior, starting, braking, protection. Control without or with closed loop control via computer. Comparisons and selection criteria. Uses of systems to electric transport, electric and hybrid vehicles, lifts, hoists, overhead conveyors, buildings and industrial facilities, heating, cooling, air conditioning, other energy units etc. Contribution systems to save energy.
Laboratory: The laboratory part of the course includes configurations of electric drive systems with or without electronic power converters, testing of systems in steady state and transient state under various conditions, technical control applications with or without a computer.

Expected Course Outcome At the end of the course, students will be able to
• To know the structure and operation of the electric drive systems.
• To know the behavior under various conditions as well as the used control techniques.
• To know the selection criteria and application fields in energy units and facilities, as well as their contribution to energy savings.
