網路監控獨立型太陽能之功率追蹤控制系統
Internet Monitoring System for Power Point Tracking on Stand-Alone Photovoltaic Control System
摘要
本論文主旨在以網路隨時監控獨立型太陽能最大功率追蹤系統。當日照強度及溫度改變時，系統經由擾動與觀察法得到最佳的最大功率輸出點，再以LabVIEW擷取其輸出資訊，讓使用者能透過網路隨時掌握太陽能電池的效率。 本論文主要是由數位信號處理器DSP TMS320 F2812做為控制核心，運用其高速的信號處理速度進行控制運算，並以LabVIEW 人機介面來設計網路監控系統，隨時監控太陽能電池的輸出資訊。本論文是以擾動觀察法為基礎，藉著週期性地增加或減少負載的大小，改變太陽能電池端電壓及輸出功率。反覆擾動、觀察及比較，進而使太陽能電池達到最大功率點。

This thesis monitored the system of maximum power point tracking (MPPT) for stand-alone photovoltaic control system on the internet. When the sunlight intensity and temperature changed, the system will achieve the maximum power output by using perturbation and observation algorithm and access the information of output by LabVIEW. Then users can get the efficiency of solar cell on the internet everywhere and anytime. In this thesis, the major control system is using digital signal processor TMS320 F2812 to design the program. Controlling and counting with high-speed signal processing speed design a human-machine interface (HCI) by LabVIEW to monitor the output power of the solar cell on the internet. This thesis is based on perturbation and observation algorithm, by increasing and decreasing the load cyclically to change the output power and terminal voltage of solar system. Keeping perturb, observe and compare to make the solar cell achieve the maximum power point.
