Title: Discussion on synchronization strategy for digital longitudinal current differential protection
Abstract: One of prerequisites for the digital longitudinal current differential protection is to make sure the synchronization of both sides.Based on the analysis of different synchronization problems happened inside the digital longitudinal current differential protection,influences of various technical strategies for synchronization on protection algorithms are compared,from which synchronization strategies for different technical sections are independent and related to each other.As to the current vector synchronization of both line sides,with their own advantages and disadvantages,the absolute synchronization strategy,emphasizing on synchronization sampling clock,and the relative synchronization strategy,emphasizing on the influence of communication time delay,may cooperate in some cases.
