大量的化(hua)石能(neng)源應用導致全球范(fan)圍內的環(huan)境污染問題(ti)不斷惡化(hua)，因此(ci)需要在(zai)減(jian)少(shao)化(hua)石能(neng)源使用的同時開(kai)發利(li)用清(qing)潔能(neng)源 [1-2]。近年來(lai)，隨著我國對節能(neng)減(jian)排問題(ti)日漸重視，電(dian)(dian)(dian)力行業加強了對風電(dian)(dian)(dian)、光伏發電(dian)(dian)(dian)、核電(dian)(dian)(dian)與(yu)水電(dian)(dian)(dian)等清(qing)潔能(neng)源領域的投資 [3]。

　　其中，光伏發電具有清潔、環保、資源分布不受地域限制等優點 [4]。近年來，隨著光伏發電技術的高速發展及國家政策的大力支持，光伏產業得到了很大程度的發展 [5-7]，當前光伏發電呈現出“規模化分散開發、低壓接入、就地消納"的局面，光伏發電技術成為較成熟的一項新能源發電技術 [8]。單相防逆流電表用于光伏并網系統CE認證

　　在我國當前的電力系統中，配電網是從輸電網獲取電能并將電能配送到用戶的重要環節，具有點多面廣的特點 [9]。將光伏電力融入到現有配電網中，可以實現配電網重構，而配電網重構是優化主動配電網運行方式的一種有效途徑 [10]。單相防逆流電表用于光伏并網系統CE認證
