An Approach to Optimizing the Structural Reliability and the Reliability of the Control and Safety System of Wind Turbines
From the past experience one may anticipate that the reliability of the control and safety system of wind turbines (WTBs) for electric power generation is too low compared to the structural reliability. May the failure probabilities of these two sources of failure be balanced and may the total probability of failure be possibly reduced (optimized), then it must be expected that the price of the turbines may be reduced. Such a result would especially be relevant to the planned enlargement of the Danish offshore wind turbine farms. In this paper we explore whether such an imbalance is really present.
