【Abstract】 Delay uncertainty problem may happen in the transferring process of the distributed relay system which takes substation Ethernet to be communication networks. Introduction was made to the transmission time delay constitute and its characteristics. Simulation software OPNET was adopted to carry out communication time delay simulation for the typical distributed relay system, the results of the analysis verified. Detailed strategy of reducing time delay uncertainty was given to lay the foundations for the corresponding product in the distributed relay system.更多还原
