Reliability evaluation of transmission systems

Key Words: Reliability, transmission system, availability, reliability block diagram, markov analysis, fault tree analysis, radial configurations. Energy is an indispensable source for humankind. It continues its existence all of our lives as lighting, producing, heating etc. The electrical energy has an important place in these energy types. The reliability conception has been developed for transmitting the electric energy which is very important for our lives to the last costumer as uninterrupted and clear. Reliability refers to the ability of power system components to deliver electricity to all points of consumption, in the quantity and with the quality demanded by the customer. In this thesis study, the meaning of the reliability is described and the conceptions of the reliability are explained. By using reliability calculating techniques, the assessment of the reliability is done in energy transmission systems.
