Training objectives
- The aim of the course is the study of the unsteady behavior and of the control of energy systems (steam power plants, gas turbines, cogeneration systems, hydro power plants) and of fluid machines (pumps, compressors and internal combustion engines).
The course provides the physical-mathematical background and the methodologies for the analysis of the unsteady behavior and of off-design operating conditions for the above-mentioned machines, in order to evaluate the most proper control logics. Particular attention is paid to system modeling in unsteady conditions, by presenting examples of model implementation in Matlab® environment and carrying out practical lessons in the IT lab. Prerequisites
- Fundamentals of mathematics and physics.
Energy systems.
Fluid machines. Course programme
- The course is composed of 60 hours of both classroom lectures and tutorials.
The main topics developed during the classroom lectures (48 hours) are:
• Mathematical models of unsteady flow in open systems (4 hours)
• Dynamics and control of compressors and operation at off-design conditions (12 hours)
• Dynamics and control of energy conversion systems (steam power plants, gas turbines, CHP systems, hydro power plants) (26 hours)
• Dynamics and control of internal combustion reciprocating engines (6 hours)
During the practical lessons carried out in the IT lab (12 hours), the students will develop simulation models of selected energy conversion systems in Matlab® environment. Didactic methods
- Lessons will be highly interactive and supported by lecture notes and references to specialized books.
Several practical lessons will be also held in the IT laboratory, to develop simulation models in Matlab environment. Learning assessment procedures
- The oral exam aims at checking the level of achievement of the previously mentioned didactic goals.
To pass the exam, a candidate has to exhibit basic knowledge on all course subjects and ability to implement simulation models; the mark (in the range from 18 to 30) depends on the understanding and rigorousness about course topics. Reference texts
