The transmission network data stored in the energy management system (EMS) can be utilized. A transmission network planning analysis system based on EMS is proposed
which provides a multi-graphic views support platform of integration of graph
model and database based on IEC 61970 standards. In this system
a planning transmission network model based on the network model
dynamic graphic and database of on-line EMS can be expanded easily
and the function of security verification and economic analysis are also implemented fully and practically for planning network. The system architecture
main functions
support platform and some key techniques are described in detail. The system proposed has been put into real practice in Shenzhen Power Supply Bureau and proved practical.
