Design And Application Of Relay Protection Remote Control On Power Supply Enterprise

Relay protection device is to protect the network security. With the"Beijing-Tianjin-Hebei integration", Baoding area economy make a spurt of progress,electricity demand growth is particularly evident, in recent years the grid scale doubled. Gridscale rapid growth necessary to bring the frequent changes of network mode, the workload ofthe operation of relay protection device of rapid growth, caused by the operation of relayprotection device existing restricted "electric power dispatching control integration"scheduling.Facing the increasing pressure, the remote control of relay protection has become theinevitable trend of development, but due to the lack of uniform and reliable protocol model,the existing technical scheme change the original system too big, in a short period of time cannot effectively popularized in large area.Based on the above reasons, this thesis firstly research on the relay protection, substationmonitoring system, dispatching automation system, relay protection and fault informationsystem, power line channel protocol model, channel equipment etc，In-depth comparison,research and analysis relay remote control program. Then,design a set of technical scheme, iscompatible with existing equipment, only need a small amount of upgrading, can realize thelarge scope of coverage. Finally, through the pilot operation proves that the design scheme iseffective, can bring great social and economic benefits.
