3239 Electrical Part of Power Stations – Course Work
ECTS credits: 4
Weekly classes: 0lec+0sem+0labs+2ps
Assessment: project defence
Type of exam: course project presentation
Departments involved:
Department of Electrical Power Engineering
Faculty of Electrical Engineering, Electronics and Automation
Lecturer:

Abstract:
The objective of the course work is to improve student’s knowledge in designing the electrical part of distribution
power system 110/6-20 kV.
Course pre-requisites: Electro technical materials, Theoretical electrical engineering, Electrical machines,
Electrical measurements, Electrical apparatuses, Electricity supply networks and systems and Technique of higher
voltages and Short circuits.
Outgoing connections: Relay protection, Electric equipment, Electricity supply.
Course content:
Electrical research involving: choice of the primary (major scheme) of the power station; calculating the current
during normal regimes and short circuit in the distribution systems high and middle voltage; choice of exploitation
regime for work of the star centre for the networks high and middle voltage.
Choice of: commutation apparatuses (circuit-breakers and disconnectors); current and voltage measuring
transformers; flexible and hard connectors for electric circuit for high and middle voltage; insulators; fuse for
protection of the circuits "own needs" and "measurement"; serge arresters for protection from overload. The
graphical part of the course work includes: full one line scheme of the PowerStation; preliminary plan for covered
distribution system; diagrams of cells for middle voltage; scheme for control, measurement lock.
Teaching and assessment:
The designing of the course work is performed through individual assignment, which includes: the parameters of
the distribution system high and middle voltage of the power station; calculated powers and length of the network’s
middle voltage, powered by the PowerStation; the relays supply turn-off times.
The course work is handed over at the end of the term. The final exam mark is complex and depends on the
design and the defence of the course work.
3240 Electrical Drive
ECTS credits: 5
Weekly classes: 2lec+0sem+2labs+0ps+1ca
Assessment: exam
Type of exam: written
Departments involved:
Department of Electrical Power Engineering
Faculty of Electrical Engineering, Electronics and Automation
Lecturers:
Assoc. Prof. Dimo Nejkov Dimov, MEng, PhD, Dept. of Electrical Power Engineering, tel.: 082 888 659,
E-mail: dnd@uni-ruse.bg
Abstract:
The subject acquaints the students with the mechanics and energetics of the electrical drive, electromechanical
characteristics of the DC and AC electrical drive as well as different operating modes of the electrical machines.
The purpose of the subjects is for the students to receive practical and theoretical knowledge of different kinds of
electrical drives and their application.
Course pre-requisites: Mechanical Engineering, Mathematics, Physics and Electrical machines.
Output links: Electrical Equipment and Electrical Transport.
Course content:
Mechanics of the electrical drive. Energetic of the electrical drive. Electromechanical characteristics of DC and
induction electrical drive. Special electrical drives. Electrical drives with static power converters.
Teaching and assessment:
The theoretical basic issues on all topics from the syllabus that are presented at the lectures are further practiced
during the laboratory exercises through investigation of the examined electrical drives and formulation of individual
reports and through the course assignment. Students should prepare in advance for the laboratory exercises. The
exam is conducted in written form and consists of two subject questions. The final exam mark depends on the
mark from the laboratory exercises and the course assignment, which has to be submitted before the start of the
exam session.
