The Research of CIM Modeling for Transformer Protection and Input Loop of the Power Secondary Networks

In view of existing situation of the inconsistent power system model, a method of CIM modeling for power secondary system is given, based on better understanding and the analysis of the primary system CIM modeling. Combined with the particular characters of the secondary system, it establishes CIM model for the transformer protection and the input loop of the secondary networks. Then it shows the method is proper and feasible. Some important issue about further research is put forward as well.
