風力發電用永磁發電機的開發

摘要：風力發電用永磁發電機（PMG），是在轉子上裝有永磁體的多極低速發電機，可直接與風輪連接而運轉，具有維護性能優良的特點。本PMG的開發中，選定最佳的磁體尺寸與配置，對各部的溫度進行研討，利用FEM（有限元法）分析手段對運轉中的外力及由磁力引起的PMG變形進行了研究與檢測。而且，通過實際的負荷試驗測定了電氣特性等，已確認質量可靠，設計參數完全符合要求。 敘詞：風力發電 永磁體 發電機 電氣特性 Abstract：PMG for wind-power generation is a kind of multi-pole low-speed generator with its rotor having PM installed. This allows for the direct connection of wind wheel, thus enjoying the advantage of easy maintenance. By this research, optimal manget size and configuaration are selected, temperature of each part is fully matched, and FEM analysis tool is used to look into and test PMG distortion resulting from outside force and magnetic force when it is in operation. Furthermore, real loan testing measures the electric features and verifies that the PMG is reliable and parameters completely meet related requirements.
