  • 近年來由於環境汙染與石化能源所剩無幾的情況下,再生能源逐漸成為各國發展的重點,其中又以太陽能最具優勢,其優點有能量取之不盡用之不竭、發電過程安靜無汙染。基於此,本文研製一台具三階段能量管理及遮蔽狀況下最大功率追蹤之太陽能電源系統,三階段能量管理可增加太陽能板利用率及系統穩定度。改良的擾動觀察法可克服太陽能板被遮蔽時所造成的影響,所提太陽能系統的操作原理與設計亦被詳細的分析與討論,最後實作一台2 kW的電路進行測試,實驗結果顯示本文提出的方法確實可行。


    In recent years, because environmental pollution and fossil energy will be run out soon, renewable energies are becoming the focus of the development worldwide. Among them, solar energy is the most attractive. The advantages of the solar energy are quiet, clean and inexhaustible. This thesis aims to study and implement a photovoltaic power supply system with three-stage energy management and maximum power point tracking (MPPT) capability under partially shaded conditions. The three-stage energy management can increase the utilization of solar panels, and raise system stability. A modified P&O MPPT method is also realized to overcome the problems due to solar shading effect. The operating principles and design considerations of the studied photovoltaic system are analyzed and discussed in details. A 2-kW laboratory prototype was implemented and tested. The experimental results are shown to verify the feasibility of the proposed scheme.
