The research of feeder automation based ONn IEC61850

To accelerate feeder automation detection and fault solution, this paper applied the communication protocol and related technologies of IEC61850, proposed the information exchange among the feeder terminals, and improved GSE model which provided a function of fast and reliable input/output value in the whole system. Adopting the layered IP network communication theory, it divided the entire network into the backbone network and the branch network, and constructed a three-layer FA architecture. The three layers respectively were master station layer, slave station layer and terminal layer. Logic nodes supplied by IEC61850 were used to accomplish the modeling of TTU information in the paper. And then, it discussed the realization of terminal self-describing. Finally, this method was applied in the DAS, and it achieved the purpose of accelerating the detection and fault solution and improving the power distribution reliability.
