Course content

The main objective of the course is to learn how to perform power system analysis in normal operation and 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 outcome

Knowledge:
After completing this course the candidate shall understand:
- methods for power system analysis in steady state operation and during grid faults,
- the principles for regular power flow and optimal power flow methods,
- the main principles for modelling and analysis of power systems subject to symmetrical and unsymmetrical faults,
- the mathematical formulation and use of symmetrical components.
- modelling of transformers, lines and cables in the positive, negative and zero sequences based on physical models,
- the impact of different earthing principles,
- the basic principles for power system protection.

Skills:
After completing this course the candidate should be able to:
- establish and use power system models based on nodal admittance and impedance matrices for analysis of large networks,
- define, establish and solve equations for regular power flow and DC power flow,
- define and use optimal power flow methods,
- use simulation tools for regular and optimal power flow,
- model generators, transformers, lines and cables in the positive, negative and zero sequences as a basis for analysis of symmetrical and unsymmetrical faults,
- perform power system analysis subject to symmetrical and unsymmetrical faults.

The student will also have increased his/hers abilities to:
- work independently and in groups,
- use instruments and equipment in the laboratory.

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 (80%) and project work (20%). 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.
