中文摘要 | 根據25個氣象測站長期地紀錄每小時平均風速(1961-1999),本研究分析臺灣地區風能密度與風力發電機特性資料,評估其風能潛勢。預測風能潛勢可分成兩個必須的階段。首先根據臺灣全島的年平均風速分佈與風能密度分佈,以分析臺灣全島風能潛勢的空間分佈資訊。模擬結果發現新竹以南臺南以北的西部沿海一帶、澎湖離島地區、蘭嶼離島地區、恆春附近與東北角一帶等,頗具風能開發的潛力,年平均風速值均達3 m/s以上,其中以澎湖離島的年平均風速最高,約為5-7 m/s左右。進一步再以萊利分佈建立風速及風能的數學模式,預測2種不同風力發電機的風能產生量,並討論其影響因子包括切入風速、率定風速及切出風速等。本研究選取5個位於臺灣西部地區風速較大的氣象測站,將這些測站的每月風速資料與每月風力發電機特性資料作比較,以求得臺灣各地區適當風力機選擇的分析結果。本研究結果可提供做為設置風力電廠的參考,使乾淨的風能得以發展,進而減少對環境的污染。 |
英文摘要 | Wind energy characteristics and appropriate wind turbine selection in Taiwan have been analyzed based on a long-term measured data source (1961-1999) of hourly mean wind speed at 25 meteorological stations across Taiwan. A two-stage procedure for estimating wind resource potential is proposed. The yearly wind speed distribution and wind power density for the entire Taiwan is firstly evaluated, which indicates that there exists outstanding wind resource (the yearly mean wind speed is larger than 3 m/s) in the areas along the western coastline between Hsinchu and Tainan, southern peninsula, northeastern corner, and several small surrounding islands, especially the Penhu island having the yearly mean wind speed over 7 m/s. A mathematical formulation using the Reyleigh wind speed distribution is further established to estimate the monthly wind energy generated by a wind turbine operated at linear relation of power between cut-in and rated wind speed and constant power between rated and cut-out wind speed. The monthly wind energy characteristics for five meteorological stations with high winds are investigated. The results show the general availability of wind energy potentials across Taiwan, which can be used to locate the appropriate wind power plants. |
