A review on reliability methods for wind farms

Abstract

This is a review paper that the reliability evaluation methods for wind power systems are reviewed and compared. The paper is helpful for knowing about the state of the art in the area and selecting a suitable method for reliability evaluation of wind system. A common set of reliability methods and procedures used in wind energy applications systems are reviewed. A quantitative measure of reliability estimation using these methods is essential for making intelligent decisions in the operation of the wind system. These methods have been classified into some categories easy to understand and to insure that the reliability requirements have been met. Several methods have been developed to address these objectives but no unique method can address all the objectives. Reliability methods present both advantages and shortcomings and are the basis for the recommendation that have been made along the qualification and quality assurance in order to improve design and manufacturing robustness.
