[[alternative]]Study of Stand-Alone Photovoltaic Power System Monitoring

碩士電機工程學系[[abstract]]本研究旨在利用獨立型太陽光電能發電系統，透過所設計監測系統來了解其特性及掌握運作狀態。本研究發電系統主要是由3組陣列太陽能板、太陽光電能充電器、鉛蓄電池、換流器、自動市電切換系統(Auto Transfer Switch, ATS)等所組成。監測系統主要使用LabVIEW軟體開發，包含太陽能板電壓／電流、充電電壓／電流、放電電壓／電流以及發電度數監測系統。本研究之太陽光電能板總功率為3.99 kW，最大充電電流可達25 A，而太陽能板產生之最大電壓可達300.5 V，最大電流為1.85 A。透過監測軟體配合硬體感測結果顯示，每日發電量可達3.12 kWh。經實驗結果得知，本監測系統能將發電資訊及數據完整的記錄，更可提供日後研究參考之依據。[[abstract]]ABSTRACT This study designs and implements a monitoring system for stand-alone photovoltaic power system. The users can understand the characteristic of the photovoltaic power system and its operation stats through this monitoring system. The stand-alone photovoltaic power system consists of three groups of array solar panels, solar chargers, batteries, inverters and an Auto Transfer Switch (ATS). The monitoring system utilizes LabVIEW software to monitor solar panels voltage / current, charge voltage /current, discharge voltage / current and provide the reading of generated electricity. In this study, the total power of solar panels is 3.99 kW, the largest charging current can reach 25 A, the largest voltage is 300.5 V and the largest current is 1.85 A form solar panels. From the experimental results, the generated power can reach 3.12 kWh every day. Furthermore, the proposed monitoring system can record the information and data of the generating electricity completely, and they can be as the reference for the future research work
