Electric Power Engineering

Course Description

Importance of energy, energy supply, energy conversion constraints. Energy forms and sources, classification of energy forms. Renewable and non-renewable energy sources. Transformations of primary energy forms into more usable forms and transformation of electrical energy into other forms of energy. Engineering thermodynamics and power cycles. Fossil fuel, nuclear fuel, solar thermal and geothermal energy. Use of hydro and wind energy. Photovoltaics, fuel cells and other direct energy conversions. Electrical energy and power system: generation, transmission, distribution and usage. Planning of electrical energy consumption. Energy efficiency and electrical energy storage. Environmental impact during generation, transformation and consumption of energy (environmental pollution and climate change). Sustainable development and energy.

Forms of Teaching

Lectures

Teaching the course is organized in two teaching cycles. The first cycle contains seven weeks, mid-term exam, and the second cycle contains six weeks of classes and a final exam. Classes are conducted through a total of 15 weeks with weekly load of 4 hours.

Exercises

Exercises are held each week with an hourly load.

Laboratory

Laboratory exercises are held every other week with an hourly load.
