Subject description


  • Enrolment into the program.

Content (Syllabus outline):

  • Basic principles of reliability, safety, risk and their mutual relationship.
  • Basics of probability theory, set theory and Boolean algebra.
  • Measures of reliability and safety of facilities and devices. Risk criteria. Risk informed decision making.
  • Methods for assessment reliability and safety – theory and examples: loss of load probability, distribution indices (system average interruption frequency index, system average interruption duration index), effective load carrying capability, fault tree, event tree.
  • Common cause failures – methods and examples.
  • Improvement of reliability of power systems and devices: redundancy, independence, separation, fail-safe principle, single failure criterion.

Objectives and competences:

Students will obtain basic information about safety and reliability in electrical power engineering. They will learn the basic methods and indices about assessment of reliability. They will get knowledge about importance of reliability of particular components and overall systems and their impact to safety and economics of specific facilities or systems. The safety culture will be emphasised and responsibility for safe and reliable use of energy will be stimulated.

Intended learning outcomes:

Ability of assessment of improvement of reliability with consequent increase of related costs. Judgement of efficiency of future investments to real power systems considering improvement of reliability indices and consequently increased costs.

Learning and teaching methods:

  • lectures or individual consultations,
  • supervisor of seminar work.
