台灣政府要推動產業創新和轉型，認為海上風力發電是一個很好的選擇。經過幾十年的實驗，各個領域的海上技術經驗已經成熟，特別是在歐洲，風能已成為許多國家的重要電力來源之一。根據國際機構4C Offshore統計，全球前20處離岸風能最佳潛力場址有18處位於台灣海峽，政府預計於2020年新增陸域及離岸風力發電量652MW，而中長期計畫則將在2025年時達到累計發電量4,200MW，因此為了獲得台灣西部離岸風力發電場的可靠離岸風場資源信息，本研究選用WindPRO軟體進行分析，使用在軟體中的幾個模塊，包括Meteo,Park,Optimization模塊等等，透過WindPRO軟體的分析，可以計算出風向，風速，年度發電量和尾流損失以及透過不同的優化方式來找出最佳化的風場排列方式，而其中尾流損失計算是選用N.O. Jensen Wake Model。將選取兩塊相鄰的彰化地區離岸示範風力發電場址，來探討兩塊風場所造成的交互影響及尾流效應，進而透過擬真的分析，可以得知最恰當的風機間距，得知該如何得到最佳之風場效益。

The government of Taiwan would like to promote industrial innovation and transformation, and believes that offshore wind power generation is a possibility. After decades of experiments, the experience of marine technology in various fields has been matured, especially in Europe, wind energy has become one of the most important power sources in many countries. According to the international agency 4C Offshore statistics, the top twenty offshore wind energy potential sites are located in the Taiwan Strait, and the government is expected to add land and offshore wind power of 652MW in 2020, while the medium and long term plan will reach the cumulative power of 4200MW in 2025. In order to get reliable offshore wind resource information of offshore wind farms in western part of Taiwan, this study uses WindPRO software to analyze and use several modules in the software, including Meteo, Park, Optimization module and so on. Through the analysis of WindPRO software, the wind direction, wind speed, annual power generation and tail loss can be calculated and the different optimization methods are used to find out. The optimal arrangement of the wind field, and the calculation of wake loss is N.O. Jensen Wake Model. Two adjacent offshore wind power sites in Changhua area will be selected to discuss the interaction and wake effect caused by two wind places. Through the pseudo true analysis, the most appropriate fan spacing can be learned and the best wind field benefits can be obtained.
