N2 - In this paper, the protection latency time between traditional and intelligent substations are compared and analyzed. In traditional substation, the analog information such as current and voltage are tranmitted to the protection and control devices via electric cable, while in intelligent substation the introduction of digital protection devices and intelligent substation prolong the protection time, which brings safe threaten to the cutoff of power system fault. The compositions of operation latency time are compared in each link and two major different time latency links are analyzed in details, and the mechanism of time latency is investigated and the effective meausures to reduce the protection latency time are proposed. Finally, the experiment of protection time comparison between two is carried out and the results prove the validity of theoretical analysis.
