Fault types. Analysis of balanced faults. Direct and symmetric-component analysis of unbalanced faults, and their relation and limitations. Core principles used for protection, including some signal-processing aspects. Future challenges, including consequences of increased renewable generation.
FEI3340 Fault Analysis and Protection Principles in Electric Power Systems 10.0 credits
Advanced studies in Power System Protection and Safety. Analysis of faults in balanced and unbalanced conditions is covered more thoroughly than in the corresponding second-cycle course, including students' own numerical implementations. Fundamental principles and blocks of protection systems are also studied in more depth, including use of established simulation programs and own implementations. Students further specialise in subareas of relevance to their research interests, with reading, project work and seminars; this specialised study is finished with a report, which is welcomed to be in the format of a paper in a conference or journal.
Information for research students about course offerings

Content and learning outcomes
Course contents
Intended learning outcomes
After taking this course the student should be able to demonstrate the ability to:
- Describe analytically, and implement numerically, methods for circuit solution of faulted power systems.
- Implement in software a protection algorithm for sampled data.
- Contrast good and bad points of different protection principles for various applications.
- Define and discuss ways in which changes in power systems, in particular the move towards a sustainable energy supply, affect the demands on protection systems now and in the future.
- Search, select, and critically evaluate suitable sources for obtaining new, detailed knowledge about a research topic within the course's scope.
- Present their new knowledge accessibly in oral and written form.
Literature and preparations
Specific prerequisites
Completed master-level education or equivalent. Students are typically expected to be doctoral students in subjects within the Electric Power area.
Recommended prerequisites
Courses or equivalent experience corresponding to EI2439 Power System Protection, particularly EG2100 Power System Analysis. Familiarity with power system components is helpful. Circuit solutions will required for ac and transient state, and matrix algebra will be used for numerical solutions of networks.
Equipment
Nothing beyond availability of a computer.
Literature
Course material will be specified further for each round of the course. It is based on several books and many further resources of published articles and manuals and the course's own notes and assignments.
Examination and completion
If the course is discontinued, students may request to be examined during the following two academic years.
Grading scale
P, F
Examination
- EXA1 - Examination, 10.0 credits, grading scale: P, 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.
The common part of the course is examined based on several assignments and on a final written examination. The specialization is examined based on the final report and on the presentation and discussion at seminars. The subject of the specialization is defined by the student, and must be approved by the examiner before getting started.
Other requirements for final grade
All the four parts of examination must be approved in order to pass the course: assignments, written examination, presentations and final report.
Opportunity to complete the requirements via supplementary examination

Ethical approach
- All members of a group are responsible for the group's work.
- In any assessment, every student shall honestly disclose any help received and sources used.
- In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
