Abstract

The paper describes a method for the reliability and safety assessment of wind turbine control and protection systems. This enables the qualitative and quantitative reliability analysis of these systems and calculates an appropriate set of reliability indices. The method for the probabilistic safety assessment of these systems includes the event-tree approach for identifying all possible unsafe events of wind turbines operation and all scenarios that can lead to them. The Markov procedure is used for the modelling of all failure modes. This method is compatible with the existing respective international safety standards and criteria; it can be used by designers, manufacturers and certification institutes. The analysis of a part of the control and protection system of the CRES wind turbine in Agios Efstratios is also included.
