Computer Modelling and Simulations
FEKT-BPMSAcad. year: 2017/2018
The course deals with computer modeling and simulation with emphasis on energy use. The aim is to manage major computer programs to support simulation. In the classroom, the students gradually learn the main methods of creating computer models and ways of implementing simulations with these models. The emphasis is generally focused to explanation for theories such as the physical domain, the relationship between the differential and flow variables, generalized laws of electromagnetism. Exercises take place practically on computers and students learn directly apply the theory in practical examples.
Learning outcomes of the course unit
The student will be able to:
- analyze real physical system and identify the inputs, outputs and state variables
- explain the difference between static and dynamic system
- describe the importance of physical domains and their main value
- create a simple simulation program in MATLAB / Simulink
- create a simulation program in an environment DYNAST
- choose a suitable computer program for the job in the energy sector
The student who select the subject should be able to explain the basic laws of electric circuits. General knowledge is required at the level of bachelor's degree, but it is advisable to have higher knowledge with work on PC in Windows operating systems.

The aim of the course is to improve students' practical skills in working with the computer to solve simple physical problems related to electrical engineering and power engineering. Students should acquire skills that enable them better address many problems that occur later in the study of power engineering. Emphasis is focused on understanding the principles and fundamentals of mathematical models and simulation process.
With only practical instruction on computers students receive routine habits, which they use in both study and practice. They will be able to make an informed choice, which method and computer program to choose for solving a specific problem, which appears to be a key element.
Specification of controlled education, way of implementation and compensation for absences
Computer exercises are optional, but students during training earn points for activities and solutions of short tasks. Term project is mandatory and is a condition of submission graded assessment.
