• consequences of faults in components of electric power systems
• electric hazards to people and property
• overcurrent protection in low-voltage systems
• electric shock protection 
• instrument transformers and other sensors
• different generations of protection relays
• system earthing and earth-faults in medium voltage distribution networks
• protection principles in distribution networks including time and overcurrent 
• protection of transmission lines: differences from distribution 
• differential protection and distance protection 
• transformer faults and protection schemes
• generators and motors 
• new challenges: sustainable development, new types of generator, DC-networks, higher speed, new algorithms, more communication

After passing the course, the student shall be able to

• give an account of basic concepts in power system protection
• solve standard problems from the major part of the course content.

To obtain higher grades, the student shall be able to

• with progression in both completeness and width, make clear and justified assessments and calculations from all parts of the course content including problems that require synthesis from different parts of the course content and qualifying courses.

Also recommended is the course EH2741 Communication and Control in Electric Power Systems.

The course is not suitable for students who have not already studied at master's level in electric power engineering.

All literature needed for the course will be provided through the Canvas page, as files or as links.  The main sources are some books available electronically through KTHB.  Additional sources are manufacturer brochures and specific course material such as slides, assignments and solutions.

Report writing can be done with free choice of program.  Several tasks in the course are intended to be done in Matlab or  Simulink (Simulink is a part of a full Matlab installation).  These can be obtained through KTH Software Download (here) for Linux, Mac and Windows.  If you want to use alternatives you're free to: e.g. Octave or Python for programming types of task, and some other power-system or circuit simulator for simulations. However, Matlab and Simulink are recommended in order to fit with the guidance given in the tasks.

Students at KTH with a permanent disability can get support during studies from Funka:

Funka - compensatory support for students with disabilities

A, B, C, D, E, FX, F

• PRO1 - Project Work, 3.0 credits, Grading scale: P, F
• TEN1 - Written Examination, 3.0 credits, Grading scale: A, B, C, D, E, FX, 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 course's credits are split equally between tasks PRO1 (Pass/Fail) and an examination TEN1 (A-F).  When both are passed, the final course grade is the grade from TEN1. 

PRO1 will be passed if a mean of 50% or more is obtained over all the tasks except the lowest-scoring one. The tasks are the weekly assignments, and one further task requiring attendance of guest lectures.

The TEN1 grade will be based 1/3 on the score from the longer project about distance protection (not included in the weekly tasks), and 2/3 on the score from the final written examination. 

• 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.
