- Abstract
ABSTRACT Many engineering systems incorporate prognostics and health management (PHM), which consists of technologies and methods to assess the reliability of a product in its actual life-cycle conditions to determine the advent of failure and mitigate system risks. Wind turbines are among the systems that incorporate PHM to reduce life-cycle costs and increase availability. Although cost-benefit models that quantify the value of implementing prognostics within systems exist for wind energy systems, they do not specifically quantify the value of decisions after a prognostic indication. This paper introduces maintenance options as a means to quantify the value of decisions after a prognostic indication. A case study on a US land-based wind farm is discussed. An analysis of wind turbine maintenance data is presented, and the maintenance options methodology is then demonstrated to establish the value of the wait-to-maintain option. The value of waiting after a prognostic indication is determined using a model that quantifies the benefit that results from a PHM implementation that allows the decision maker to delay maintenance actions, thereby using the remaining life of the system components rather than throwing it away.
