EG2020 Power Systems, Basic Course 7.5 credits

The course is given in English, and treats models and computation methods for power systems. The models and the methods are general and can be applied to industrial power system and local distribution networks as well as to national transmission networks. In the course assignments these models and methods are applied to solve realistic problems with computer programs written in MATLAB.

The following areas are treated in the course:

Symmetrical phasors: Three-phase systems, one-phase equivalents, the per-unit system, circuit theorems, admittance matrixes, impedance matrixes, load flow analysis, models of components in power systems such as lines, generators, cables, transformers, loads etc.

Unsymmetrical phasors: Symmetrical components, calculation methods, models of transmission lines, transformers, generators etc.

Load flow analysis: Problem formulation, models, solution methods.

Power system dynamics: Stability of dynamic systems, Lyapunov functions, modeling of power system components for transient stability analysis, stability of power systems, equal area criterion, rotor angle stability, voltage stability.

Upon completion of the course the

student will be able to

• Describe how a power system is designed and operated.
• Explain static and dynamic states in a power system.
• Explain the various causes of power system collapse.
• Create computational models for analysis of both symmetrical and unsymmetrical conditions in power systems.
• Perform load flow computations with the help of the Newton-Raphson method.
• Analyze the load flow results.
• Create computational models for analysis of power system dynamics and stability.
• Apply the theory to real-life problems.

Courses in electrical engineering 45 (HEC), courses in mathematics (including complex numbers, algebra and numerical methods) 30 (HEC), also documented proficiency in English B or equivalent.

Course compendia

If the course is discontinued, students may request to be examined during the following two academic years.

• TEN1 - Examination, 7.5 credits, grading scale: A, B, C, D, E, FX, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

One written examination, 7,5 cr.
