Based on the modeling framework introduced， an analysis is made of the IEC 61970 and IEC 61850 standard series， which focuses on their abilities of modeling. In view of the specific characteristics of substation and control center application， the levels and scopes to be coordinated are provided: for the principal level， it is suggested that the association between the measuring and protecting equipment， as well as some new data models for the protecting equipment， be added; for the design level， a basic data model in conformity with the IEC 61850’s logical node be added， along with its necessary derivations that are needed to describe the solution at the design level; for the implementation level， the extension to RTU model in IEC 61970 is inevitable， and a new model with respect to remote setting and server should also be added.
