Skill Praxis M - HEN

• Hidroenergetika, Semester 4, position 1

The goal of professional practice is that students in addition to theoretical work within subjects at the faculty get to know and experience the jobs in factories, institutes, laboratories and similar commercial enterprises and thereby gain insight into the activities to be performed. During the practice, students must keep a diary in which they enter a description of the tasks performed, and write down their conclusions and observations. Following the practice, students must write a report that is to be discussed about with the subject teacher.

On successful completion of this course, students should be able to: 1. Write a report with a completed skill praxis, 2. Describe the operation and organization of the appropriate energy system or facility, 3. Demonstrate acquired practical experience and skills, related to specific jobs in the appropriate energy systems or facilities, 4. Acquire and develop team skills in work environment (communication with colleagues, professional ethics, etc.).

The course content is practical work, which consists of spending working time in certain organizations that perform various activities in mechanical engineering. The choice of a theme as well as a business or research organization is made in consultation with the concerned teacher. Students may perform their practice in: design and energy consulting profession organizations, organizations that produce and maintain power equipment, organizations that build and maintain power plants, waterworks companies and laboratories of the Department of hydraulic machines and power systems.

In the design and consultancy organizations, students are introduced to the process of design and analysis of power plants, acquire practical knowledge of engineering graphics, use of modern computer programs for designing and analyzing equipment and facilities, implementation of measures for rational use of energy and environmental protection and others. In organizations that produce and maintain power equipment they are acquainted with the process of equipment production, technological lines of production, quality control, and others. Within the companies for the construction and maintenance of power plants they acquire knowledge about the organization of construction, layout of equipment and technological systems in plants, and others. In power plants they get to know the appropriate processes, technology systems, fixtures and equipment, methods, process analysis, measurement of process parameters, operating the plant, and others. In the laboratories of the Department of hydraulic machines and power systems they can become familiar with the available equipment and measuring equipment.
