Educational Goals

The aim of the course is to provide basic practical knowledge as regards various applications of electronic systems for energy management and saving in industrial production processes. These systems are currently more frequently used and applied in industries with high electrical and thermal energy consumption. In addition, the area of energy saving and relative techniques in industry, is an area of great significance for the operation of modern industries, as energy is a key part (and in some cases the most important) of the daily operating expenses and therefore of the cost of the end product. The course introduces and presents modern practices for electrical energy management in industry as well as targeted interventions and solutions for the improvement and more efficient use of energy. Areas that will be covered include the introduction of electric vehicles, power electronic converters for special purposes, high efficiency power supply units, UPS systems, power quality and harmonics issues in industry, active filters technologies, electronic control of reactive power, induction heating, heat and electricity cogeneration systems, BMS systems and efficient utilization of energy storage systems. As a selective course, it offers valuable experience and expertise to the new industrial and management engineer, as regards a developing field of electronics applications with focus on the management and saving of energy. The consistent and successful completion of the course, has the expected outcome to enable the student to:
a) understand the importance of energy and the systems for its management and saving, as a key component of every production process.
b) know about the latest technological developments as regards systems that efficiently manage energy offering solutions to industry.
c)be in a position to understand the problems of non-efficient energy use and to be able to propose, design and study specialized approaches.
d) assess basic technoeconomic information and results of energy management and saving systems.

General Skills

Practical application of knowledge, search, analysis and synthesis of information and data using appropriate technologies; Adjustment to new situations; Decision making; Autonomous work; Team work; Work in an interdisciplinary environment.
