垂直軸風力機磁浮轉盤磁塊架構最佳化分析

本文主旨乃針對「垂直軸風力發電機」的「磁浮載重磁盤」內部磁塊，以不同間距配合環狀、塊狀磁塊以固定轉速作「磁抗力」與「抗重」作模擬分析，進而結合實際運作時狀況，探討其穩定性。本研究所使用之磁塊及其模擬進行方式，基本上是依照「行政院原子能委員會核能研究所」計畫案中－「前瞻型中小型風機系統」－分析方式執行；主要是依其實體結構，由上、下載盤之「環狀磁塊」及區分為八等份之面積、體積、大小之環狀磁塊，並以相同模式嵌入磁盤，再以Ansoft Maxwell 3D（磁浮分析軟體），依據永久磁鐵之相吸、斥力原理進行，進而檢視整體「風力發電之機組」各零件之負荷；記錄結果並分析求得其最佳值。

The purpose of this study mainly focuses on the simulation and analysis of ”magnet resistance” and ”anti-weight” with various gap, shape, and fixed speed in the inner magnet of ”magnet load disk” of ”Maglev vertical axis wind turbines”. Most importantly, discussing its stability by involving with actual factors during real world operational conditions. The entire analysis process is in accordance with one of the projects of ”Institute of Nuclear Energy Research Atomic Energy Council”, ”Advance vertical style of small and medium wind power system”, the analysis is on the basis of its physical structure starting from the identical area, volume, and size of eight equal portions in the upper-side and lower-side load disks of ”ring magnets”, then continuously embedding different magnet disk with same procedure. Ultimately, according to the original principle of permanent magnet (attraction/repulsion) by using Ansoft Maxwell 3D (a magnetic analysis software) to accomplish the work. The results indicate that the most valuable parameters of its stable state (including loading) in every part of components can be obtained from simulations. In addition, the optimal situation for this system can be obtained and is useful for future reference.
