臺灣博碩士論文加值系統

　　本論文的目的是設計與實現一套具有換流器故障偵測功能的太陽能馬達驅動及市電並聯系統，此系統是由太陽能電池、充電器、電池組、直流截波器、換流器及數位信號處理器所組成。其中，我們利用基於梯度法之最大功率追蹤法則使得太陽能模組可持續地輸出最大功率，太陽能電池的輸出功率被用來對蓄電池充電及供給換流器所需的直流匯流排電壓。在本論文中，我們使用均勻充電器來對串聯電池組充電以延長蓄電池壽命，在換流器的調變方法方面，我們使用電壓空間向量調變法以減少電流諧波，並且可使換流器的直流匯流排電壓有效地被利用；同時本論文亦利用換流器之輸出電流來偵測換流器之故障狀態。又利用電壓源換流器，使太陽能電池所產生的電能可直接與市電並聯供電，可解決夏季尖峰電力不足的問題。
最後，利用實驗結果證實本論文所製作之系統特性與理論分析結果相近，因此可驗證本系統之可行性。

　　This thesis presents the design and implementation of a photovoltaic energy motor drive system and utility grid connection system with the inverter fault detection function. The system is composed of the photovoltaic modules, batteries, DC chopper, voltage source inverter and digital signal processor. This system uses a maximum power point tracking technique based on the gradient method to continuously apply the maximum power of the photovoltaic modules. The output power of the photovoltaic modules is used as the input voltage of the battery charger and the voltage source inverter. The charge equalization technique for series connected battery strings is adopted to charge the batteries. The voltage space vectors pulsewidth modulation method is used to minimize the current harmonic distortion and effectively utilized DC bus voltage of inverter. Moreover, a diagnosis method based on the output current of the inverter is used to detect the inverter faults. Utilizing voltage source inverter, the photovoltaic system can deliver power to the utility, and it can help to reduce the summer peak power supplied from utility equipment.
Finally, the experimental results are provided to show the performance of the photovoltaic system and verify the feasibility of the proposed system.
