The standard of the communication networks and systems in substation-IEC61850,and the substation configuration language(SCL) recommended by IEC61850 are introduced.The object-oriented self-description function involved in SCL technology is analyzed.On the basis of it,the static configuration of a simple substation is completed,and then the dynamic display and longdistance access of the substation data are researched based on Web browser.As SCL and the IEC61850 general model are combined,the configuration information of the substation and the device are clearly depicted,furthermore the configuration management of the substation is easily realized by transmission of the SCL file.It is available for reference in understanding the trend of the substation communication technology and developing the substation communication system conformed to IEC61850.
