Electrical Power Generation
FEKT-BKC-VEEAcad. year: 2020/2021
The course acquaints students with the conversion of different forms of energy from natural resources into electrical energy and heat. During the course the students will get acquainted with the different types of energy in the nature and especially with the technological processes of its transformation into electrical and thermal energy in thermal, nuclear and water power plants. Part of the subject is a brief introduction to the issue of function and use of renewable energy sources.

Planned learning activities and teaching methods
Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.
Teaching consists of lectures, laboratories and numerical exercises. The communication platform of the course is on e-learning. Students will complete laboratory assignments defined by the Guarantor's Decree for the current semester. One technical excursion is planned.
Assesment methods and criteria linked to learning outcomes
Point scoring of written and oral examination is held under the rules of FEEC.
During the semester, students pass three control written tests, laboratory tasks and voluntary individual tasks. Requirements to get the credit are to obtain at least 20 points from 40 possible and NONE of the required activities (laboratory tasks) is evaluated with 0 points.
The final exam is evaluated by up to 60 points and is divided into written (arithmetical problems - 30 points) and an oral part (30 points). Necessary requirement to pass the examination is to obtain at least 15 points from the written part and at least 10 points from the oral part.
