Learning outcomes of the course unit
Students gain knowledge in the field of measurement, control and regulation of energy systems. They get to know the basic types of control circuits in energetics, their key components and the issue of appropriate use of these components.
Prerequisites
Boilers, Heat turbines and turbocompressors, Heat turbines I., II.
Planned learning activities and teaching methods
The course is taught in blocks. In the first half of the semester there will be only lectures that have the character of an explanation of the basic principles and theory of the discipline. In the second half there will be an exercise, which is focused on the practical mastery of the material covered in lectures.
Assesment methods and criteria linked to learning outcomes
Exam – written, oral part. The exam will be divided into two parts with a total achievable number of points of 100. Each part of the exam will have a achievable 50 points and will be divided between the examiner.
Credit – conditions of award: participation and active work on exercises.
