摘要

本文针对风电机组运行到达机组设计寿命时

是否仍具有剩余使用寿命进行了研究。提出了基于定制化载荷分析和可靠寿命复核的风电机组剩余使用寿命评估方法

分别计算机组结构承载部件在认证设计条件下和现场条件下的等效疲劳载荷和许用循环周数

结合延寿因子和不确定度计算来评估机组结构承载部件的剩余使用寿命。将该方法应用于评估某老旧风电场750 kW风电机组的使用寿命

结果表明

该750 kW机组运行达到设计寿命后

各结构部件均存在剩余使用寿命

机组可至少延寿运行5.5年。

Abstract

This paper studies whether the wind turbine still has remaining service life when it reaches the design life. Based on customized load analysis and reliable life review

a method of residual service life evaluation for wind turbine is proposed. The equivalent fatigue load and allowable number of cycles of the wind turbine are calculated respectively under the certification conditions and the on-site conditions

and the remaining service life of the wind turbine structural components are evaluated by lifetime extension factors and uncertainty calculation. This method is applied to evaluate the service life of a 750 kW wind turbine in an old wind farm. The analysis results show that

after the 750 kW wind turbine reaches the design life

all components have a remaining service life

and the wind turbine's service life can be prolonged by at least 5.5 years.
