Course abstract

The aim of the study course is to acquire types of centralized and autonomous electricity supply technologies, specific character of direct voltage transmission, specific character of agricultural objects power supply, designing and valuation of electrotransmission lines, power supply automatization and control, simulation of power supply technologies using MATLAB subprogram Simulink.

Learning outcomes and their assessment

Knowledge - types of power supply sources for industrial and agricultural installations and their characteristics, the construction and application principles of the apparatus, the electricity networks and the principles for their operation and control - tests 1 and 2.
Skills - to carry out engineering calculations and, according to the relevant criteria, choose the type of connection of power plants and the equipment needed — home works 1 and 2.

Competence - selection of the type and parameters of the power supply sources and the justification thereof, selection of the electrical connection and justification thereof - home work, examination.

Description of the organization and tasks of students’ independent work

1st homework. To design and calculate the equipment for connection of small HPP, wind and solar power plants to common electrical networks.

2st homework. To develop and calculate the equipment of biogas cogeneration for the station and the replacement of the diesel generator for connection to the common electrical grids.

Criteria for Evaluating Learning Outcomes

The assessment of the study course exam depends on the cumulative assessment of the exam assignment and the study course test papers and homework. A test or an exam is passed if at least 50% of the test questions are answered correctly. The homework assignment is evaluated in accordance with the assessment procedure specified in the assignments of homework. The exam mark is calculated as the arithmetic mean of the exam assignments and the average semester mark, which is calculated as the arithmetic mean of the marks of tests and homework taken from the study course.
