基于电压前馈的光伏逆变器低电压穿越控制策略
LVRT Control Strategy of PV Based on Voltage Feed-forward Control
摘要
Abstract
Low voltage ride through technique has become one of the most important technologies of PV inverter. A grid voltage feed-forward control method was presentd, which can effectively restrain the over-current while grid voltage drop down, and as far as possible to the power grid to provide reactive power support. Experiments prove that the method is rapid and accurate judgment voltage low voltage fault, realizes low voltage safety through of the PV inverter.
