摘要:	本計畫首先將自行設計，研製一套3D 掃瞄量測系統，來量測在使用中之風機系統(Whisper 500)葉片外形輪廓，以得到翼剖面之模型。從所獲得之葉片3D 尺寸，本計畫一方面將分析其翼剖面所構成葉片之效益與精準度，並利用現有的數學模式，求取風能轉換效益，並配合中小型風力發電機現有效益(0.85~0.95)，求取實際之風機全系統效益，提升原有系統之轉換能量；另一方面以現有之3D 資料庫求取本實體量測系統所量得之數据，利用最小平方和法求取其間之實体差異，作為改進量測糸統之精度，進而提升其性能並降低未來3D 實體量測系統成本使之進入產業界更有吸引力。以量測現有之Whisper 500 双槳葉片為目標，本計畫先依須求自製一長行程線性量測平台,其組件包括:3.0 米X 軸移動台、光學尺、3D 取像探頭、探頭支撐架、 PID 控制器、及無刷直流馬達等共六項次糸統。本量測系統特色為: 設計可量 0.5 米至3.米複材或特殊材貭之多曲度葉片、創新之控制PID 光機电整合控制介面、以簡易之一般無刷直流馬達透過自行撰寫之軟体以省电式晶片控制各項介面信號、利用NI 影像擷取卡作影像斷點補償、配合線雷射光投影之非接觸式影像探頭等。葉片實際之3D 實體，利用雷射影像掃瞄探頭將取得之影像透過二值法、濾波及細線化技術得到葉片各截面的曲線，並由座標映對法轉換成3D 空間之資料，其中包括不連續資料之恢復及斷點之補償，來達到三維的逆向還原，求取原始資料。再利用曲面擬合法重建葉片之三維資料，最後經由既有建妥之氣動力資料做比對，以獲得所需之風力性能數據, 做實際比對，以求取葉片最佳性能、最大轉換效率、與最高可靠度，為最終目的。 The project goal is to develop a 3D Scanning Measurement system (SMS) to scan and measure the profile of a wind turbine blade (Whisper 500 Wind Turbine System). Using the data from measurement to: (1) analyze the accuracy and efficiency of wind turbine blade, (2) analyze the whole wind turbine system efficiency to increase the amount of power conversion efficiency (0.85~0.95) and (3) get the variance and standard deviation between the database and the blade to improve the accuracy of SMS, Not only can the SMS performance be improved the performance of SDSWN but also the system cost can be down so as to attract the commercial competitiveness in the future. The target for the developed SMS is to measure the blade of a Whisper 500 twin-blade wind turbine system. The primary objective is to design and fabricate an long travel linear measurement platform, including 6 subsystems: (1) a 3.0meter X-axis moving platform, (2) a linear scale, (3) a 3D scanning head, (4) a head supporting frame, (5) a PID controller and (6) a brushless DC motor. The special characteristic techniques are: (1) to measure the FRP wind turbine blade length from 0.5 m to 3m with multi-curvature, (2) to design an innovative double-loop integral PID controller with opto-mechatronics interface, (3) to develop a line laser projector with non contact image sensor and to output image signals, (4) to compensate and smooth the image discontinuous data, and (5) to study the signal synchronous loop design for synchronizing signals from double-loop control,(6) to control a DC motor with a energy-saving chip connect several interfaces. Using the laser image scanning head and image processing techniques can acquire following goals: binarization, noise removal and line thinning. After the completion of sectional 2D airfoil curve fittings, 3D world coordinates of the cloud data of the full wind blade can be obtained through the function mapping method with respect to the image coordinates. Finally, the surface-matching method from commercial library tool will be used to reconstruct real 3D shape of the blade. Those measured data will compare with the ideal data stored in the data base. The shape error can be calculated. This project not only can get the best solution of the wind turbine transfer energy but also can auto-tuning the measurement parameters and improve the SMS performance.
