Summary of the subject: The theoretical foundations of the thermal process of stationary steam and gas turbines are highlighted. The general principle diagrams of steam and gas turbine installations of heat energy facilities, and thermal and nuclear power plants are presented. Methods of design selection and thermal calculation are considered. The main features of their operation in stationary and transient modes of operation, the technical characteristics of modern types of steam and gas turbines are presented. Regulation and protection systems are described. Basic information about condensing devices is given. The principles of designing capacitors, their thermal calculation, as well as auxiliary equipment of condensing units are considered.

Assessment methods and criteria: Examination control is carried out during the examination session in written and oral form.
Current monitoring of practical classes is carried out with the aim of identifying the student's readiness for classes in the following forms:
• a selective oral survey before the start of classes;
• assessment of the student's activity in the process of classes, submitted proposals, original decisions, clarifications and definitions, additions to previous answers, etc.
Examination control is carried out in the form of a written and oral survey and/or test control.
The final control is carried out based on the results of the current control and semester examination control.
Критерії оцінювання результатів навчання: Semester control - exam
Current control (30%): written reports on calculation works, oral examination.
