Electric Power Systems and installations 1 (ELK220)

This course introduces students to three-phase analysis and modelling of transmission lines, transformers, loads and the power system in general. The course also introduces students to low voltage installations aspects such as dimensioning, safety and regulations.

The content of this course is related to both fundamentals of power system analysis and introductions to low voltage electric installations.

Power system analysis:

The three-phase system with associated transmission and distribution networks, as well as associated switching facilities with transformers, lines/cables and other components. Analysis of stationary conditions that includes voltage drop and power calculations, inductance and capacitance in cables, as well as modeling of transmission lines. Load and short-circuit calculations including load distribution calculation of active, reactive and apparent power. Circuit diagram for electrical installations, including one-line diagram. Documentation in accordance with applicable norms and regulations. Introduction to the use of digital tools for calculation and simulation of electrical installations, including Matlab. There will be practical laboratory work.

Installations:

Introductions to low-voltage distribution systems (IT, TT, TN) topology and dimensioning of circuits. Circuit drawing for electrical installations, including single-line and multi-line diagrams. Safety measures for installations with regard to safety for people, fire and operation, with a focus on induced voltages, overloads and short circuits. Calculation of fault currents. Introduction to regulations and guidelines, including the Electricity Supervision Act.
