摘要：The rapid development of photovoltaic (PV) generation systems has made the low voltage ride-through (LVRT) techniques, which is stepping forward fast, more and more important. This paper presents a review of LVRT techniques for PV generation systems, which mainly focuses on the critical techniques of fault detection and grid synchronization, current control and dc-link voltage control under various voltage dip operation conditions and overall solutions for a large-scale PV station with detailed illustration. Besides, the development trends of low voltage ride-through techniques for PV generation systems are discussed as well. © 2014 IEEE.
