Calculation system, wind power generation system, or calculation method of remaining life or fatigue damage of windmill

摘要

An object of the invention is to provide a computing system capable of estimating parameters such as remaining life with high accuracy from operational and environmental information, a wind power generating system, and a method of calculating the remaining life or the fatigue damage quantity of a windmill. In achieving the above object, there is provided a computing system for acquiring the remaining life or the fatigue damage quantity of a windmill rotated by wind. The computing system includes a computing device configured to acquire relations between operational information or environmental information about the windmill on the one hand and the remaining life or the fatigue damage quantity of a predetermined member included in the windmill on the other hand, the relations being acquired by use of distortion information about the windmill.
