本研究利用風力能與太陽能做為夜間路燈照明的能源,白天利用太陽能與風力能發電儲存於蓄電池,晚上提供路燈電力,並利用風力繼續發電補充電能;設計250W的永磁發電機與太陽能並聯運轉;在設置條件相同時,太陽能發電輸出主要受到太陽能板的種類與面積所限制,在同樣陽光下,大幅改進並不容易。故本研究主要在設計製作永磁式風力發電機,並探討與太陽能並聯運轉的供電品質。因風速係隨高度增高而增強,但一般照明設施之高度太低,所以風能相對較小,須要低轉速即可發電的高效能風力發電機,為達到最佳化,將配合業界生產技術能力,使理論與實驗數據相互印證,以提昇小型風力機的設計製作能力。
In this research, the utilization of the wind and solar energy for street lamp is investigated. The electrical energy generated by above renewable energy source store in battery. Because the energy generated by the solar cell limited by the area, it is difficult to improve greatly. To compensate the energy at night, the wind turbine is necessary. In general, the street lamp is not installed too high. In this research, a 250W permanent magnet generator(PMG) designed for low speed operation is proposed. In addition to the conventional lab test, the PMG undergo the field test at the tower in SJSMIT campus. The performance of PV-wind integrated system is also examined to validate the feasibility.
