複合材料風力機之研製---總計畫(II)

Abstract

本總計畫延續上年度的工作，研究將所開發之複合材料風力葉片及盤式發電機組 立一由複合材料風力葉片、盤式發電機、塔架、交流電安全控制器、變頻器、直流電 安全控制器和蓄電池所組成的風力發電機系統，供各子計畫進行與系統功能及可靠度 相關的試驗。本總計畫下含三個子計畫，其中子計畫一「風力機系統設計與保固之研 究(II)」是研究風力機系統的流場及風壓分布，並探討葉型參數對風力機發電效率的 影響；子計畫二「風力機關鍵零組件之研製(II)」是研究複合材料葉片的結構完整性 及修補與延壽技術；子計畫三「風力機試驗平台與可靠度試驗程序之建立(II)」是研 究系統中重要元件的可靠度及系統中噪音的成因識別與防治。本總計畫將協助各子計 畫建立長期監測的系統，藉量取風力機系統的風速、風壓、振動、應變、噪音、發電 量（功率）及損傷等數據，以建立系統參數的資料庫，供系統效率及可靠度評估、系 統修補及延壽，噪音防治等課題的研究。本總計畫將整合各子計畫的研究成果，提出 一小型風力發電機系統的設計與試驗準則，可作為未來規範訂定的參考，亦可供將來 設計新葉型或較大型風力發電機系統之參考。

In this year’s project, the composite blades and disk-type generator developed and fabricated in the previous project will be used to fabricate a wind power system which is composed of three composite blades, a disk-type generator, a tower, an AC safety switch, an inverter, a DC safety switch, and a charge battery. The wind power system is then set up for long term testing and health monitoring. This project contains three sub-projects which will use the wind power system to perform different tests and measurements. Sub-project 1 with the title ”Wind turbine system design and health maintenance study(II)” studies the aero-dynamic characteristics and efficiency of the wind power system using the measured data. Sub-project 2 with the title “Fabrication technique of wind turbine critical parts(II)” studies the endurance property of the composite blades and develops repair techniques to extend the life of the blade. Sub-project 3 with the title “The development of testing procedures for quality assurance of wind power system(II)” studies the reliability and noise control of the wind power system via an experimental approach. This project will assist the sub-projects to collect the required data through different types of measurements. Finally, this project will integrate the results obtained by the sub-projects to propose design and testing criteria for small composite wind power system. These criteria can also be used as reference for designing larger composite wind power system.
