IEC 61850 is the latest and the only effective international standard on substation automation communication. The grid-connected interface device for distributed photovoltaic power generation combines relay protection, measurement and control, power quality control, telecontrol, harmonic control and other functions of distributed photovoltaic power generation equipments. It manages the distributed photovoltaic power generation equipments as a whole and is an important interface device that realizes plug and play. It is necessary to the smart grid that grid-connected interface device supports IEC 61850. In allusion to the information model construction and information interaction of grid-connected interface device for distributed photovoltaic power, distributed energy control field related logical devices and logic nodes defined by the IEC 61850-7-420 are introduced into the IEC 61850 information model of traditional power distribution terminal, and information model and information exchange model of grid-connected interface device for distributed photovoltaic power based on IEC 61850 are given.
