Introduction to Electric Power Systems

• Identify differences between a simple electric circuit and a three-phase power system
• Explain the structure of a power system
• Describe power system components and explain their functions
• Select appropriate models for power system components
• Calculate power system quantities by means of the per-unit system
• Determine operational limitis in a power system
• Calculate balanced three-phase short circuit currents
• Explain the power flow problem and approaches to solve it
• Summarize operation principles of a power system in terms of control of voltage, active and reactive power
• Design a realistic power system
• Evaluate the overall performance of a power system under different operating scenarios by means of a power flow program

– Power grid
– AC circuits, 3-phase systems, power considerations
– Components in the grid like transmission lines, cables, transformers, generators and more.
– Power flows and tools for simulation
– Symmetrical faults

The topics from the text book can be supported by topics from related areas.

In the project, a realistic problem will be defined and has to be solved by means of the numerical simulation program PowerFactory (load flow) with graphical user interface.

Basic knowledge within AC-circuits and main AC components.

a) Lectures and group exercises in connection with the lectures
b) Assignments to be handed in every second week
c) Power Flow simulations. Group projects, where the power system will be investigated by modelling of af minor, realistic grid. Participation in the project and quality of the work will be evaluated by a number of peer-to-peer meetings.
