- 摘要
- 本研究首先以國際電工委員會(International Electronic Committee, IEC)所公布的風力機設計規 範IEC 61400-1或IEC 61400-3-1中，針對數種不同設計載重組合中的設計風況內容予以定義上的說 明。接著採用四種不同的方式，分別為風洞實驗、由美國再生能源實驗室(NREL)所開發的FAST程 式的TurbSim模組(FAST V8版)、由丹麥科技大學(DTU)所開發的HAWC2軟體、基於MDSRFG的模 擬風場等四種，重現設計風況的風場歷時，針對代表風場特性的平均風速剖面、紊流強度剖面、紊 流積分尺度剖面、擾動風速頻譜、以及擾動風速交頻譜等，進行與IEC規範的差異性比對。本研究 結果顯示，FAST的FAST V8版TurbSim模組及DTU開發的HAWC2有其不足之處或受限於規範風況的 定義，相較於此，基於MDSRFG的紊流產生模式則可以藉由調整風場參數來模擬各種流場。最後， 本研究所採用的複數風扇風洞則能針對多數地穩態風場及部分的非定常氣流進行物理模擬並提供給 縮尺模型進行氣動力量測試驗，可作為一種進階的驗證工具。

- This study has adopted four approaches to simulate wind conditions specified in IEC 61400-1 and 61400-3-1 codes for wind turbine designs. These four simulation approaches include the physical simulation technique via wind tunnel facilities and three numerical simulation techniques. For the physical approach, an actively controlled multiple-fan wind tunnel and a conventional boundary layer wind tunnel at Tamkang University are utilized for the flow simulation. The Cobra probe is used for wind speed measurements. For the numerical approaches, the TurbSim module in the open-source program OpenFAST developed by the National Renewable Energy Laboratory and the HAWC2 developed by DTU are conducted and compared with the self-developed MATLAB program based on the MDSRFG theory. For those stationary wind conditions, such as NTM, ETM, and EWM conditions, vertical wind profiles of mean wind speeds, turbulent intensities, and turbulent length scales are compared with the IEC codes and the speed spectra and co-spectra. Simulated wind time history signals by the multiple-fan wind tunnel are also compared for non-stationary wind conditions, such as EOG and EWS conditions. Results show that the TurbSim and the HAWC2 approaches do not reproduce the wind conditions fitting with the IEC codes very well. However, the self-developed MATLAB based on the MDSRFG theory can almost reproduce the IEC wind fields in genuinely good quality. Although the multiple-fan wind tunnel cannot reproduce the horizontal EWS condition and the EDC/ECD conditions, it shows a good agreement in simulating the vertical EWS condition and the EOG condition. The multiple-fan wind tunnel provides a good reference tool for validation of the wind field simulation and the further possible aerodynamic force measurements.
