摘要
Abstract
The influence of the grid power quality to the PV Inverter step-up transformer is analyzed in the actual operation. The formula for added loss calculation is given considering the influence of harmonic current, which is verified by an actual small-capacity transformer. The difference between PV inverter step-up transformer and ordinary power transformer is confirmed. The vector group for transformer is analyzed, and the reasonable vector group ofYd-11 is determined.关键词
