To solve the problem of information acquisition and exchange, a comprehensive monitoring information model based IEC 61850 is proposed for DER accessing in the grid. The model adopts the object-oriented abstraction method to abstract the logical devices as function node, analyzes the supervising information of 10 kV distribution network of DER grid-connected and finally defines the data objects as logic function nodes. In the end, this paper makes the PV DER grid-connected as an example, chooses typical logical nodes in the generating subsystem and the electric combined point to illustrate the monitoring information model of different grid-connected patterns.
