Application of CIM model for enterprise wide power system model for Planning, Protection and Operations

Powerlink Queensland is currently in the advanced stage of implementing a CIM-based enterprise-wide network asset model maintenance system. This model allows a single common repository for the planned and operational network model for use by planning, operations, EMS and protection. Planners are able to enter future projects with multiple possible scenarios with the capability to move the projects or phases in the project as required. The CIM model defined in IEC#61970 has been enhanced to incorporate full representation of sequence models, mutual couplings and power system dynamic data. This parallels the effort to develop a CIM for planning reference being led by EPRI in the US. In addition, the CIM-based database is also being used as a centralized plant register for other corporate applications such as a switching sheet program and outage management system. Automatic export of the model is also provided to the EMS so that newly commissioned plant is automatically added to the model as planned projects are placed in operation.
