| Recommended semester: 7th - 9th semester |
| Scope and form: Lectures and exercises in calculation, simulation and in the laboratory. |
| Evaluation: Project report
|
| Examination: 13-scale |
| Previous course: 53256 |
| Prerequisites: 50280 / 45120 / 53114 / 92200 |
| No credit points with: C4711 / 53256 |
| Aim: The course is designed to give the students insight in the application of power electronics in the electric power supply, for example DC transmission of electric power, dynamic compensation of reactive power, improvement of the curve shape, circuits for distribution of the power in the distribution network, and connection of renewable energy systems to the grid. The course further allows the students to design power electronic circuits for very high power applications in order to assess the limits of power, working frequencies and harmonics that determine such properties as can be obtained by using the circuits in the disrtibution network. |
| Contents: Description of mode of operation and properties for various semiconductor components which may be used as electronic switches in power electronics. The arguments for using DC transmission of electric power. Description of fundamental proporties for grid-commutated and self-commutated inverters. Description and comparison of different snubber circuits for self-commutated converters intended for high power usage. Design of three-phase converters for applications in power electronics in the distribution network. Series- and parallel configuration of converters with associated possibilities of reducing higher harmonic currents or voltages. Description of possible applications of power electronics to compensate for the reactive power in the distribution network. Discussion of the possibility of controlling the power-flow and line voltage. Further presentations include the possibilities of simulating these and other circuits with the intention of predicting the effect of such power circuits on e.g. the dynamic stability of the network. Discussion of driver circuits for various power semiconductors. |
| Remarks: New course, replace the old course 53256, but is considerable expanded. |
