An information architecture of condition monitoring substation equipment system is proposed based on IEC 61850 and IEC 61970 coordination. Problems of model construction， expansion and adaptation of substation equipment information are analyzed to coordinate IEC 61850 and IEC 61970. An equipment condition monitoring and integrating platform（CMIP） supporting the unified information model and unified communication interface is designed and implemented. With this platform， comprehensive condition information of both the primary equipment and secondary equipment can be conveniently gathered and shared with other application systems.
