Reliability applied to the Preventive Maintenance on Wind Farms using Weibull distribution with a Financial Approach

Abstract

This article aims to describe the most adequate methodology in terms of period of time for the preventive maintenance items in a wind farm. The methodology is going to analyse parts of wind turbines that present constant events of corrective maintenance and determine the best period for a preventive action in order to optimize maintenance costs and maintenance time that is directly linked to the wind farm owner profit. The components that present more unpredictable failures will be recommended to an improved schedule of preventive maintenance based on historical record analysis applied to probability methods, bringing positive financial results in terms of maintenance and energy generation.
