風帶式微型發電機特性模擬與實作

目前風力發電的技術主流是以旋轉式的葉片(含水平軸及垂直軸)帶動齒輪箱及發電機來發電，大型風機可以高效率及低成本的情況下來發電，但小型風機的效率較低而且每瓦的成本也比大型風機高，造成小型風力發電機推廣不佳。本論文主要目的是研究一種新式的微型風力發電機，此發電機為美國人Shawn Frayne在2008年所發明的「風帶式發電機」。「風帶式發電機」的特點為每瓦成本低、發電效率高、不需要使用特殊材料、容易維修改善、沒有旋轉零件的磨損以及低噪音等。本論文將透過電磁理論來模擬「風帶式發電機」的相關電力特性，研究參數變化對其電壓輸出的影響，並實際製造出一台「風帶式發電機」，透過此發電機的實際所測量之數據來驗證模擬結果的正確性及補足模擬不足之處。測試結果顯示本論文模擬結果能正確預估實測數據。並可協助微調各種參數，以提昇「風帶式發電機」的效能。

Current mainstream of wind power technology is using the rotary blades (including horizontal axes and vertical axes) to drive gearbox and generator to produce electricity: The large wind turbines can produce power energy with high efficiency and low cost, but the efficiency of small wind turbines is lower than that of large wind turbines, and the cost per watt is higher. It leads to ineffective promotion result for small wind turbines. The purpose of this thesis is to study a new type of micro wind turbine. This generator is called "windbelt generator" and invented by the Americans Shawn Frayne in 2008. The characteristics of "Windbelt generator" are low cost per watt, high power generation efficiency, need not use special materials, easy maintenance and improvement, no wear of rotating parts and low noise. In this paper, the electromagnetic theory is utilized to simulate the electric characteristics of the windbelt generator and to study the effects of parameter variations on generated voltage. In addition, windbelt generator is actually built to verify the accuracy of the simulated results and make up the inadequacy of simulation. Test results show that the simulation can predict the experimental test data. And the parameters can be tuned to improve the performance of “windbelt generator”.
