摘要

台灣的風力機廠牌與機型多元且多樣化，使得維修為一大問題，若風力機發生問題因而閒置時，對風場投資回收或風能資源利用都有不利之影響。維修若受制於原廠，會使維修之時程無法掌握，有受制於人之虞，因此，建立自主性風力機維修檢測技術為重要之工作。
本文將以Vestas V47 660 kW風力機葉片積層作為基礎，從已知之積層疊序設計材料試驗，並進行修補之試片試驗，因應不同之破壞模式探討修補之效果，並於試片有限元素模型中使用膠合元素以及使用者副程式模擬葉片修補後之力學行為。最後維修葉片實體，藉此建立FRP風力機葉片之維修程序，使得葉片的有效運轉率提高。

The wind turbines used in Taiwan come from different manufacturers. The maintainance and repairs will cause problems because the schedule is controlled by the turbines manufacturers. The idle wind turbines for malfunction are unfavorable for the investments and the utilities for wind resource. Therefore, capabilities in inspecting and repairing the wind turbines are very important.
This study investigates on the simulation and process of the blade repairs. A 660 kW wind turbine blade is taken as an example. The material tests which include the specimens of base laminate and repaired specimens from the laminations of the 660 kW blade are designed. The efficiency for different repairing methods is investigated by the material tests of repaired specimens. Then finite element model with cohesive elements is used to simulate the structural behavior of the repaired specimen. Based on this, the capabilities in repairing damaged blade are established, which will be beneficial to availabilities of wind turbine blades.
