Research of IED communication equipment in digital substation

WANG Bo,YOU Da-hai,XU Guang-wei,XIAO Wei-qiang(Huazhong University of Science and Technology,Wuhan 430074,China)  
IDE is the pivotal equipment in substation integrated automation system,and is an important factor of sustaining substation to develop toward digital substation.For resolving communication problems among IDE equipment,a digital substation communication model based on IEC61851 communication protocol is brought forward in the paper.The model can realize the data sharing among IEDs,it is suitable for equipment mutually operation,network expansibility and high dependability,it is adaptable to the characteristic and requirement of digital substation network too.This model offers a reference for the realization and development of IDE network.The paper describes IEC61850,three layers network configuration of digital substation automation system and how to communicate among IEDs by using IEC61850.
