Development and application of power grid model integrated server system

In general, power system dispatching adopts partitioned network monitoring mode and detailed power network models are built only for dispatching systems at different levels, and the rest part of power network external to the monitored part is represented by equivalent network, so there is obvious discrepancy between the equivalent mode and actual rest part. To meet the demand of different power network application and analysis systems, a power grid model integrated service system is designed, which not only possesses three core function modules, i. e., model splicing, measurement merging and graphic display, but also the application functions such as custom-made model, transient model matching and applied analysis of power network are extended, in addition, a unified Web service interface for the third party system is provided. Practical application shows that the designed system can meet the requirements for power network models and data from various power application systems.
