Design of Database Integration of Grid Online Monitoring System Based on Middleware
Mao Chen-lin · Power System and Clean Energy · 2012
With the development of smart grids,the on-line monitoring system for major equipment and transmission lines has become an effective means for the operation and maintenance of the power transmission facilities in large substations.With increasing of on-line monitoring systems,however,theinformation isolated island problem has become more and more prominent,which directly complicates the management.Therefore,there is an urgent need to integrate these independent on-line monitoring systems and realize sharing of the information,namely,realize the integration of heterogeneous data.To this end,this paper,firstly introduces the characteristics of the data integration for the on-line monitoring systems for power grids and then the middleware data integration.Based on an analysis of the main goal of the heterogeneous data integration and the key problems,the paper proposes a data integration solution based on middleware and the heterogeneous database for XML and JMS so as to realize the data source query,sharing,and publishing among the heterogeneous data of all kinds of the original on-line monitoring systems.
