Design and Simulation Based on 101 Protocol Transmission Mode in Distribution Network

For making remote 1 0 1 protocol adaptable to compatible application requirement of different transmission modes of modern electric automatic equipments,this paper states development history of IEC 60870-5-101 protocol,characteristics on link layer of unbalanced and balanced transmission modes of 1 0 1 protocol and necessity of transmission design for balanced mode of 1 0 1 protocol.Meanwhile,aiming at blank space in application of balanced transmission mode,it proposes selection mode design scheme for a kind of intelligent transmission mode and simulates field operational environment to proceed parameter configuration.In addition,it carries out simulation study and experimental testing.Experimental results indicate that parameter configuration is reasonable and feasible and by simulating testing and message analysis,it is able to greatly improve effectiveness for field fault diagnosis of distribution intelligent control devices in power grid communication system.
