都市大樓之小型風力機噪音與振動分析與評估-以虎尾科技大學第三綜合館頂樓為例
Analysis and Estimation of Noise and Vibration for the Small Wind Turbine Installed in Tall Bulidings-The Third Comprehensive Museum Attic in Formosa University as an Example
摘要
風能屬於取之不完、用之不盡的能源；近年來，除了沿岸大型風力發電機之外，中小型風力發電機之發展已日益進步。但當風力發電機運轉時，其所產生的震動及噪音將對附近居民生活造成影響；因此，對於風力發電機運轉時所產生的震動及噪音研究是值得探討的。 本研究主旨在探討裝置於虎尾科技大學第三綜合館頂樓，兩台不同類型風力發電機之間的差異。觀測機種為：一、風技綠能科技股份有限公司生產之WT2000型號水平軸式風力發電機；二、新高能源科技股份有限公司生產之DS300型號垂直軸風力發電機。 本研究實際觀測環境風速範圍為4~14 m/s，對上述機種進行一系列有關於振動與噪音之記錄；針對風力發電機振動狀況，以NI CompactDAQ儀器進行紀錄，並使用手機紀錄不同的風力發電機構型在不同風力大小時的噪音值。 本研究利用統計的方式進行紀錄，綜合數據歸納出結果，並進一步對量測與紀錄之結果進行分析計算及評估。可從結果得知不同的風力發電機構型對環境造成噪音影響，以及使用軟體彙整振動狀況，製成振動反應頻譜；以利未來在作風機安裝取捨時可依照數據做為安裝考量標準。

Wind energy belongs inexhaustible in supply and always available for use ;In recent years, in addition to large wind turbine along the coast, the development of small wind turbine have become increasingly progressive. But when the wind turbine operation, vibration and noise generated by the wind turbines will affect residents living nearby；Therefore, the vibration and noise studies for wind turbines operate when generated is worth exploring. This research aims to examine the device difference between two different types of wind turbine, which are provided in Formosa Un iversity, the third comprehensive museum attic. The detection models selected for the following two : (1) WindTek Green Energy Technology Co., Ltd. Production - WT2000 model Horizontal Axis Wind Turbine(HAWT)； (2) Hi-VAWT Technology Corp. Production - DS300 model Vertical Axis Wind Turbine(VAWT). The ambient wind speed range of actual observation is 4~14 m/s, and have a series of these models on vibration, noise and generation of records. The ambient wind speed range of actual observation is 4~14 m/s, and have a series of these models on vibration and noise of records. For different wind conditions, in order to record the instrument of wind turbine vibration condition by NI CompactDAQ , and use the cell phone to record different wind Institutional size at different wind noise values. In this study, statistical approach to record, summarize the results of comprehensive data, and further on the results of measurement and analysis of records of calculation and assessment. Different from the results that the wind Institutional noise impact on the environment, and the use of the software compiled vibration condition, made vibration response spectrum; to facilitate future trade-offs in the style of installation as the installation of data can be considered in accordance with the standard.
