Reliability analysis of a power electronic integrated generator for wind energy conversion systems

This thesis presents a novel design for off-shore wind turbines. Reliability analysis of AC to DC power converter architectures that are utilized in this wind energy conversion system is performed with Markov reliability and availability modeling. The three architectures under investigation are: the baseline, based on a sole active rectifier; the proposed, comprising an active rectifier and three passive rectifiers; and the proposed outfitted with electromechanical bypass relay switches. The models are used to determine reliability, system failure rate, and availability of all three architectures. Sensitivity analysis of various component failure and repair rates on the reliability metrics just mentioned is also performed. An averaged high-order model of the wind-turbine is presented and reduced using singular perturbation analysis. The reduced-order model is used to calculate the expected power output of the off-shore wind turbine.
