Intended learning outcomes

After the course the student will be able to:  

  • Know basic terminology and concepts for reliability analysis.
  • Analyse a system including the following methods and techniques for reliability analysis:
    • Network method for analysis of systems of independent components,
    • Methods for identifying critical components
    • Marcov modelling
    • Life time modelling
  • Perform power system analysis including aspects of:
    • Need and access to data from fault and disturbance
    • Availability of test systems for power system reliability analysis
    • Adequacy and security assessment
    • Protection system reliability
    • N-1 criterion analysis
    • Load point and system indices
  • Perform analysis of the power system as part of the energy system with aspects of:
    • Reliability evaluation for the Smart Grid developments.
    • Reliability worth analysis and an overall knowledge on laws and regulations to give incentives for reliability levels.
    • Life cycle cost analysis (LCC) and basic investments and risk analyses based on results from reliability and LCC evaluations.
    • Formulate a reliability based maintenance plan for maintenance management outgoing from reliability centred maintenance and have knowledge of quantitative developments like the RCAM (Reliability Centered Asset Management) method.

Course main content

This course will give a thoroughly introduction of fundamental reliability theory and basic models for analysis. The theories are generic and applicable for any technical system. This course is focused on application for electric power systems and its equipment. Examples will be given from real case studies and own research studies. The application examples include: generation (hydro, nuclear and wind), transmission and distribution and main components (cables, lines, circuit breakers, transformers) and usage and storage (smart meters and electrical vehicles). The overall objective of the course is that the participant after completed course shall be able to use reliability theory as a tool for decision support for design, operation and planning of electric power systems.


The course is divided into the following parts:

  1. Intensive course week with lectures and tutorials covering all the course material.
  2. Self-tuition and working on assignments.
  3. Examination in written exam.


Entry requirements for this course is equivalent to master exam in Electrical Engineering, or corresponding and with basic knowledge in statistics methods.

Supplementary information

The course was held in 2013 in collaboration with KTH School of Electrical Engineering, the Norwegian University of Science and Technology (NTNU), Department of Electric Power Engineering, and the Aalto University, School of Electrical Engineering. Such a joint course gives opportunity to increase the teaching capacity, cover more topics in depth, and attract a broader group of participants.


Course syllabus valid from: Autumn 2013.
