摘　　要：为提高光伏建筑一体化建设中光伏逆变器应对电网电压跌落的能力,提升建筑供电可靠性,本文以单相光伏并网逆变器为研究对象,提出恒定峰值电流控制的逆变器低电压穿越方法,实验结果表明该控制方法在电网电压不同跌落程度下具有较好的控制效果。In order to improve the ability of dealing with grid voltage drop for PV inverter in building integrated PV, and improve the reliability of building power supply, this paper studies single - phase grid connected PV inverter, and proposes a low voltage ride through method for inverter with constant peak current control. The experimental results show that the method has good control effect under different voltage sags.
