Power System Analysis, part 1

The course concerns the fundamental models and methods utilized in power system analysis. The generality of these models and methods makes them equally applicable to analysis of small-scale industrial power systems, local distribution grids, and national transmission systems.

Innehåll och lärandemål

Kursinnehåll *

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:

• Balanced system: three-phase systems, single-line equivalent, the per-unit system, circuit theorems, admittance matrixes, impedance matrixes, models of components in power systems such as lines, generators, cables, transformers, loads etc.
• Load flow analysis: problem formulation, models, solution methods.
• Optimal load flow and sensitivity analysis: reactive power dispatching to decrease power losses.
• Unbalanced system: symmetrical components, calculation methods, models of transmission lines, transformers, generators etc.
• Fault analysis: system models, and calculation of fault currents where there is an unbalanced fault.

Lärandemål *

Upon completion of the course the student should be able to

• explain static state in a power system,
• create computational models for analysis of both symmetrical and unsymmetrical conditions in power systems,
• perform an optimal power flow for reactive power dispatching to decrease power losses.
• analyze the system performance where there is an unbalanced fault, and also calculate the corresponding fault current.
