Modeling of the Intelligent Electronic Device According to SCL in the IEC61850

IEC 61850 is the latest substation automation network communication standards promulgated by the ISO.SCL is the substation configuration language recommended by the IEC61850.The use of SCL can describe the device configuration information clearly and can realize sharing of different equipment.Based on the research of the development trend of current transformer substation,this paper introduces the rules of communication model in line with the IEC61850 standard,and describes a simple model according to the requirements of the SCL model construction.The model is tested with its correctness confirmed.
