Analysis of grid-connected PV inverter low voltage ride through testing scheme
摘要
Abstract
By analyzing and comparative test for LVRT test schemes based on passive-impedance network and the grid simulator, this paper deals with the diversity in terms of the main circuit topology, voltage dip range and accuracy, instantaneous overload ability and control stability etc. The analysis and testing results show that LVRT testing scheme based on the passive-impedance network can be very closer to the actual operation condition with stable output voltage waveforms.关键词
