Course lecturers



Introduce students to the function and basic features of an electric power system as well as the basic elements (generator, transformer, transmission line and cable and consumer). Train students to independently calculate currents and voltages in simple power grids as well as to perform power flow calculations using computer programmes.

Course description

Introduction. Basic principles and characteristics of an electric power system (EPS) - definition and function of an EPS, basic elements, historical development and future trends. Electric power grid (or simple grid) - types, tasks and operation of an electric grid, electrical parameters of a grid, definitions of an active and a passive branch in a grid, definition of power in a grid, three-phase grid and single-phase equivalent. Generator - function, basic principles, electrical parameters and equivalent circuit. Power transformer - function, basic principles, electrical parameters and equivalent circuit. Transmission line - function, basic principles, electrical parameters, equivalent circuit and mathematical models for short, medium and long transmission lines. Calculations of current and voltages in a grid - method of absolute impedances and per-unit method, two-port network and basics of power flow calculations.

Course assessment

Conducting university questionnaires on teachers (student-teacher relationship, transparency of assessment criteria, motivation for teaching, teaching clarity, etc.). Conducting Faculty surveys on courses (upon passing the exam, student self-assessment of the adopted learning outcomes and student workload in relation to the number of ECTS credits allocated to activities and courses as a whole).

Overview of course assesment

Learning outcomes

1. define a power system and describe its main features and elements

2. define and explain the electrical parameters of the main elements of a power grid: generators, transformers, transmission lines and consumers

3. describe and draw three-phase and single-phase equivalent circuits for generators, transformers and consumers

4. describe mathematical models for short, medium-long and long transmission lines

5. describe the following methods for calculating currents and voltages in a power grid: absolute impedance method, per-unit method and two-port method and perform the calculations using these methods

6. describe and calculate power flows in a power grid using a computer programme

7. measure electrical quantities for transmission lines under different conditions using a laboratory transmission line and transformer simulator
