dc.description.abstract | 本研究旨在發展台灣離岸風場的風場功率輸出與風場控制之模擬。本研究以在歐盟風能計畫(Aeolus FP7)中丹麥奧爾堡大學(Aalborg University)發展出的SimWindFarm風場模擬軟體,於MATLAB/SIMULINK上進行風場全系統動態分析與設計。模擬使用丹麥科技大學(Technical University of Denmark, DTU)發展的10MW風機為原型風機,將風機系統結合風場模型與尾流模型,並加入風機控制系統以及風場控制系統,在台灣離岸風場資料下進行模擬。模擬的風場架構為一固定風向以及平均風速之風場,風場高度固定在風機輪穀(hub)的高度,並在二維的矩陣頻譜的介面上表示其風場模型和風機間的尾流效應。在固定風場布局(layout)下,研究整體產生的輸出功率。並設計不同的風況輸入風場系統,使用控制策略理論:部分分配控制與比例分配控制對風機的輸出進行控制,達到在整體台灣離岸風場系統的輸出功率變化與穩定之分析與模擬。 | zh_TW |
dc.description.abstract | This study aims to develop simulations of wind farm control and power output in the offshore wind farm of Taiwan. The study uses the software SimWindFarm that is a wind farm simulation software developed under the European Wind Energy Project (Aeolus FP7) by Aalborg University in Denmark. MATLAB/SIMULINK is used to carry out the dynamic design and analysis of wind field system. The 10MW wind turbine developed by the Technical University of Denmark (DTU) is used for the wind turbine model in the simulation. The wind turbine systems, wind farm models, and wakes models are used together to implement the simulation with wind farm control systems and wind turbine control systems by the data of offshore wind farm of Taiwan. The wind field model is on the basis of the fixed wind direction and constant average wind speed, and the height is fixed at the height of hub. The wind field model and the wake effect of wind turbines are shown by two-dimensional matrix. Under the fixed wind field layout, the simulation is carried out to investigate the output power produced by overall systems. Finally, the different wind conditions are used as the input, and control the output of wind turbines by the control strategies as partial distribution control and proportional distribution control. The simulation and analysis of variation and stability of power output for Taiwan offshore wind farm system was realized and verified. | en |
