大量的(de)化(hua)(hua)石能(neng)源應用(yong)導致全球(qiu)范圍內的(de)環境污染問題不(bu)斷惡化(hua)(hua)，因此需要在減少化(hua)(hua)石能(neng)源使用(yong)的(de)同時開(kai)發(fa)利(li)用(yong)清潔能(neng)源 [1-2]。近(jin)年(nian)來，隨著我(wo)國對節能(neng)減排(pai)問題日漸重視，電力行業(ye)加強(qiang)了對風電、光(guang)伏發(fa)電、核電與水電等清潔能(neng)源領(ling)域(yu)的(de)投資(zi) [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]。三相檢測電表用于分布式光伏并網系統

　　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]。三相檢測電表用于分布式光伏并網系統
