Course detail
Operation of District Heating Equipment
FSI-FSC Acad. year: 2021/2022 Summer semester
The course focuses on power stations (power plants, combined heat and power plants, pure heat plants) in centralised and decentralised configurations. It is followed by lectures on their implementation into the distribution grids, elementary conceptual design process, calculation of heat losses and overall energy consumption.

Learning outcomes of the course unit
The students will have basic understanding of the energetics in the Czech Republic and will be able to conceptually design combined heat and power plants.
Prerequisites
Knowledge of Thermomechanics, Fundamentals of Power Engineering I and II. Heat engines.
Planned learning activities and teaching methods
The course is taught in a form of lectures that have theoretical character containing basic principles of given subject.
The calculation classes will be based around Open Source program OpenModelica. During the semester, video-lectures will be regularly released on University Moodle website. The videos will contain theory to each section and their implementation into the program. There will be individual assignments corresponding to covered topics. At the given scheduled time for the class there will be computer lab available, where individual consultations can take place.
Assesment methods and criteria linked to learning outcomes
Credit requirements: active participation in the classes. Submission of all assignment in the field of calculations of energy equipment.
Requirements for the exam: written part in the form of questions and examples, oral discussion on a given topic
Aims
The main aim of this course is to get the students acquainted with the energetics in Czech Republic, with the construction and operation of power supply stations (mainly power plants and combined heat and power plants) and their integration to the power and district heating grids.
Specification of controlled education, way of implementation and compensation for absences
The presence on lectures is recommended and will be delivered according to the schedule.
Calculation classes: submission of all calculation assignments
