由於近年來能源問題,逐漸受到各國所重視,而太陽能是一種免費、無污染且又取之不盡、用之不竭,是一種可以利用來發電的一種相當好的能源。而目前的太陽能發電效率普遍都不高,所以如何增加太陽光電能發電系統的發電效率是值得研究的。本研究以獨立型太陽光電能負載研究與分析為主,分析負載與系統匹配的問題,以及負載諧波對太陽光電能發電系統的影響。並對負載消費電力、蓄電池容量的設計與太陽光電池模組串、併聯數,做整個獨立型太陽光電能發電系統一完整規劃。及分析獨立型太陽光電能發電系統的規劃與設置時應考慮的非技術性障礙,瞭解這些系統規劃與設置將有助於獨立型太陽光電能電力的發展。根據本研究分析太陽能板的輸出端電壓隨負載因素變化最大。因此為了穩定太陽能板的輸出電壓,本研究設計一降昇壓轉換器將不穩定的直流電源轉換為穩定直流50V電壓輸出給於後級換流器轉換為交流形式使用。建立出一最完整穩定的獨立型系統,並經由實驗之結果及測試數據證明所預期之效果確實可達成。
Due to the energy crisis, renewable energy sources have been suggested as the possible solution. Among these sources, solar energy is free and without pollution, and the supply is inexhaustible. Therefore it is a fairly good energy to generate electric power. But up to now the efficiency of solar cell is still very low, for that matter how to make the photovoltaic array works in maximum power point is worthy of research. This study focuses on the analyzing of load matching and harmonic problems of stand-alone photovoltaic power system. We propose a stand-alone system design, including the series and parallel numbers of photovoltaic modules, battery capacity and converter design, discuss the tackling of untechnical problems, and measure the performance.
