About the course
Course content
The course lays the foundation for exploring the ways and means to perform power system analysis in normal operation and under symmetrical and unsymmetrical faults. Models of generators, transformers and transmission lines essential for such analyses are assembled. Additionally, principles for the formulation, solution, and application of optimal power flow are established. Computer-aided analysis of the performance of large-scale power systems is one of the central learning objectives.
Learning outcome
Knowledge:
After completing this course, the student will be able to recognise, analyse, comprehend, and assess:
- methods for power system analysis in steady state operation
- principles of modelling and analysis of power systems subject to symmetrical and unsymmetrical faults
- the mathematical description and use of symmetrical component theory
- modelling of generators, transformers, lines and cables in the positive, negative and zero sequence systems
- the significance of different earthing/grounding methods
- the principles and application of regular power flow and optimal power flow methods
Skills:
After completing this course the student will be able to:
- establish and use power system models based on nodal admittance and impedance matrices for the analysis of large-scale power networks
- model generators, transformers, lines and cables in the positive, negative and zero sequence systems as basis for the analysis of symmetrical and unsymmetrical faults
- perform analysis of power systems subject to symmetrical and unsymmetrical faults
- define, establish and solve equations for regular (AC) power flow, DC power flow, and optimal power flow
- use simulation tools to perform comprehensive short circuit studies, load flow studies, and optimal power flow studies
The student will also have increased the ability to:
- work independently and in groups,
- use instruments and equipment in the laboratory.
Learning methods and activities
Lectures, exercises, laboratory work and project work. The course is given in English.
Compulsory assignments
- Laboratorieøvinger
Further on evaluation
Portfolio assessment is the basis for the grade awarded in the course. The portfolio comprises a written final examination (50%), a mid-term exam (20%), and specific individual and group work (together 30%). The results for the constituent parts are based on %-points obtained, while the grade for the whole portfolio (course grade) is given by the letter grading system (A-F).
If there is a re-sit examination, the examination form may change from written to oral.
If the student receives an F as a final grade even after the re-sit exam, then the student must retake the course in its entirety. Submitted work that counts towards the final grade must also have to be retaken.
Recommended previous knowledge
