摘要

台灣地區在西部沿海、東北角、屏東半島與離島擁有適合發展風力發電的土地，但受到季風氣候的影響，導致每年的弱風期（4-9月）風力發電產生的電量不如預期。另一方面，台灣地區位處亞熱帶，陽光充足、日照時數長，在每年的弱風期恰爲發展太陽能發電的最佳時期。因此本研究擬擷取風能與太陽能在不同時期的優勢且互補其不足之處，探討在台灣地區結合風能與太陽能發電之可行性。本研究以常被使用的小型Jacob10風機，做爲風能結合太陽能發電先期評估的機型，並在考慮使用較少數量的太陽能而板與複合發電系統穩定度之下，搭配2倍風機率定功率的太陽能陣列。本研究選取新竹、梧棲、恆春與成功四個測站，分別代表台灣地以北、中、南與東部區域，並利用各測站1996-1999年的逐時風速與1996-2004年平均月累積日射量，估算此四個測站風能與太陽能並聯後的總發電量，以及分析其整年度與弱風期的供電穩定度。研究結果顯示，四個地區僅靠風力發電機在弱風期的月發電量約爲500kWh，一旦加入太陽能陣列發電時，所有月份的總發電量都提升至2000kWh以上，甚至有些弱風期月份的總機電量會大於強風期月份的總發電量，可見太陽能發電確徒補助風力發電在弱風期發電量不足的現象，平衡全年度之發電穩定性。

Taiwan has significant wind resource in the areas along the western coastline, southern peninsula, and several small surrounding islands. However, the efficiency of wind turbines during weak wind periods (from April to September) is much detracted because of the climatic features of the Asia monsoon. On the other hand, Taiwan is located in the subtropical region with sufficient solar radiation and ample sunshine duration during weak wind periods. As a result, this research is to analyze feasibility of integrating wind energy and solar energy as a hybrid energy system in Taiwan. Double rating power of PV systems is used to fit wind turbine systems. Thus, 180 solar panels Kyocera-KC-120 and Jacob 10 wind turbine are integrated as a hybrid energy system to take advantages of both systems. Four locations (Hsinchu, Wuchi, Chengkung and Hengchun) in Taiwan are selected as the study eases, representing the northern, central. eastern and southern area of Taiwan, respectively. A measured data source of hourly mean wind speed (1996-1999) together with a monthly accumulated data source (1996-2004) at these four locations are studied and discussed. The result shows that the monthly energy outputs are about 500 kWh without using PV systems, but the monthly energy outputs are about 2000 kWh with the hybrid energy system during weak wind periods. It can be concluded that the hybrid energy system can improve the efficiency of wind turbines and keep the power supply stable during weak wind periods.
