Course content

Power system analysis in steady state operation and during grid faults. Building power system models based on nodal admittance and impedance matrices for analysis of large networks. Formulation and application of regular power flow and optimal power flow methods. Modelling and analysis of the power system during symmetrical and unsymmetrical grid faults. Symmetrical components. Component modeling (transformers, lines and cables) for positive-, negative- and zero sequence. Alternative earthing systems. Basic principles for power system protection.

Learning outcome

The main objective of the course is to learn about power system behaviour under symmetrical and unsymmetrical faults, including basic principles for protection against such faults. Additionally, the students will learn basic principles for formulation and application of optimal power flow.

Learning methods and activities

Lectures, compulsory exercises, compulsory laboratory work and a compulsory project work using computer programs. Portfolio evaluation is the basis for the final grade in the subject. Parts of the portfolio are final exam (75%) and project work (25%). The final grade is given on standard form as a letter code. The course is given in English. If there is a re-sit examination, the examination form may change from written to oral.
