摘要: | 本研究旨在探討傳統獨立型太陽光電系統與脈衝充電技術的結合,利用脈衝充電提升蓄電池的壽命,並藉由脈衝充電無需限流的特性確保太陽電池的發電效率。
本研究主要分為兩部分,第一部分是如何改良原有的獨立型太陽光電系統以導入脈衝充電技術,並根據脈衝特性發展兩種太陽能脈衝充電方法,包含利用兩組電池的交錯脈衝充電和利用電容儲能的電容儲能脈衝充電。第二部分則是藉由實際搭建傳統獨立型太陽光電系統、交錯脈衝充電系統和電容儲能脈衝系統實際連續運作,探討何者有較佳的太陽能發電量與發電效率。由實測結果可以發現,當每日總輻射量4000Wh/m2以上時,交錯脈衝充電系統有最佳的充電效率與較佳的發電效益。 The purpose of this study was to combine the stand-alone solar PV system with pulse charging method. The pulse charging method is used to enhance the lifecycle of battery and ensure that the power generation achieves high efficiency by solar panel because of the unlimited charging current which is the characteristic of pulse charge. First, according to the characteristic of pulse charge, we explain how to improve the traditional stand-alone solar PV system through pulse charging method and have two approaches to implement the combination, including the interleaved pulse charging which has two sets of battery and the capacitor-energy-storage pulse charging which use the capacitor to store energy. The second part of this study, we build three real systems that include the traditional stand-alone solar PV system (i-sCon 3), the interleaved pulse charging (i-sCon 3+P) and the capacitor-energy-storage pulse charging (i-sCon 3+C), and then we run these three systems for several days trying to find out what system has the best efficiency and the maximum amount of electricity generation. The results revealed that the interleaved pulse charging (i-sCon 3+P) system has the best charging performance and the maximum power generation. |
