風力發電做為綠色能源之一，近年來廣受世界各國採用，以取代傳統石化燃料發電。行星齒輪系因其結構緊緻，普遍被選擇做為大型風力發電之傳動系統。為減少大型風力發電系統設計、製造及維修成本，本論文提出一風力發電齒輪傳動系統動力模型，作為模擬分析之工具。此工具除在設計階段對參數提供模擬外，並可針對參數進行優化，減少齒輪傳動系統失效頻率，進而提升風力發電系統運轉效益。
本研究以剛體向量法與牛頓第二運動定律進行齒輪傳動系統運動與動力分析，考慮加速度對於傳動系統負載之影響，以承載2MW風力發電系統進行模型建立。利用動態特性驗證模型可信度後，加入葉片機制，取得各齒輪元件的運動及負載情況。接著，將負載結果導入AGMA規範下應力分析，試以求得齒輪傳動系統各元件應力、安全性及系統可承受之最大陣風。為驗證其可用性，本文依商轉中2MW風力發電系統導入實際風場數據情境進行應用，在不影響齒輪傳動系統的空間要求下，提出齒輪參數優化流程，得到一組優化後設計參數，由此參數分析結果，可將系統可承受之最大陣風速提升22%。

Wind power is green energy which has been extensively used worldwide as a replacement of traditional fossil fuel energy. Due to the compact structure of a planetary gear train, it is predominantly utilized as transmission systems for large wind turbines. To reduce the time and cost for designing, manufacturing, and repairing large wind turbines, a simulation model was proposed as an analytical tool for gear transmission systems of wind turbines. In addition to simulating the dynamic behavior of a transmission system, the gear design parameters can be optimized with elevated safety factors. As a result, the frequency of failure may be significantly reduced and the operational efficiency of wind turbines can be improved.
This study was conducted to investigate kinematic and dynamic behavior of 2MW wind turbines, based on the analysis of vector method of rigid body and Newton's second law of motion. Firstly, the reliability of the simulation model was confirmed with the dynamic characteristics of a 2MW transmission system. To obtain the movement and loading data of the gear transmission system, wind field data and blade-pitch control mechanism were imported. With the loading data, the contact and bending stresses will be analyzed using the AGMA strength equation, thus the safety factors and the maximum wind gust limit of the gear transmission system were derived. Lastly, In order to verify the versatility of the simulation model, this tool was further applied to an existing 2MW wind turbine with realistic wind field data for its gear transmission system. With the same transmission system space, the optimized design parameters were generated hence the wind gust speed limitation can be enhanced over 22%.
