能源安全、永續發展與環境保護，為近年來國際間備受矚目的議題，世界先進國家無不投注大量資金發展再生能源系統。在此風潮與趨勢下，風力發電成為台灣極具潛力的新興能源之一。然而，在政府及民間企業大力推廣風力發電建設之際，西元2008年9月28日於台中彰濱工業區裝設之大型風力發電機組疑受薔蜜(Jangmi)颱風之強風豪雨侵襲，造成位於場區內5座大型風力發電機之葉片產生表面剝離與裂縫。為探討本事故致災因子及葉片剝離破損之觸發機制，本文以個案分析方式，首先針對工程文件進行資料複核與研析，並統整國外類似案例，歸納風機葉片災損事故之常見災因。接續，根據資料複核的內容，進行風機葉片結構力學行為模擬，分析研判可能之致災機制，並提出災損防阻建議。研究成果期能應用於實務所需，防止爾後類似的工程事故，並可回饋利害關係人於風險管理強化與防災因應策略研擬。

Issues such as energy security, sustainable development, and environmental protection have been a major topic of international discussions in recent years. Developed countries worldwide are investing substantial sums to develop renewable energy systems. In addition to this trend, wind power generation has revealed potential as a major energy source in Taiwan. However, an accident occurred just as the government and private enterprises began heavily promoting the construction of wind power generators. On September 28, 2008, five large wind turbines (WTs) located in the Changhua Coastal Industrial Park in Taichung sustained heavy damage from fierce winds and heavy rainfall brought by Typhoon Jangmi. To examine the causes of this damage, specifically, delamination and cracking in the WT blades, this study first reviewed and analyzed data in related engineering documents. Similar overseas cases were also reviewed to identify the common causes of turbine blade failure incidents. The structural mechanics of WT blades were then analyzed with behavioral models to identify the mechanisms of the damage. Hopefully, the analytical results of this study can help prevent similar engineering incidents in the future and provide a reference for stakeholders devising strategies for improving risk management and disaster prevention in wind power plants.
