Course Contents
The course is devoted to fault calculations in electrical power systems, the economic operation and control of power systems and an introduction to power system stability.
For network calculations and the description of symmetric and asymmetric faults the general method of power invariant symmetrical components is introduced.The economic operation involves the minimization of fuel costs, while the power system control deals with the primary and secondary control on the generating units to enable stable operation and maintaining a proper grid frequency. The stability of the power system after faults is studied through the method of the equal-area criterium.
Study Goals
Students will be introduced with methods for computation fault currents and load flows. For this, symmetrical components will be studied. Power system components will be studied and adequate models for transformers, synchronous machines and transmission lines will be presented. Network calculations and short circuit analysis are studied by applying admittance and impedance matrices of the circuits. Symmetrical components and transformation from n-phase system into n separate 1-phase systems will be presented as an important tool to determine unsymmetrical fault currents (single-phase fault current, double-phase and double-phase-to-ground fault currents). Additionally, the course will be supported by computer exercises done with the commercially available software package Vision©.
Education Method
Lectures. The number of hours that the students need to spent on this is about 14h a week. This is important since it is expected students to learn symmetrical components well, so that they do not have difficulties in the future.
Literature and Study Materials
John. J. Grainger and William D. Stevenson: Power System Analysis, ISBN 0-07035958
Assessment
Oral. Students normally get theoretical questions and problems. Problem solutions are important to see if the students govern the theory well.
