Research On Application Of Message Oriented Middleware In SCADA System

With the development of dispatching automation system,SCADA system, electric energy metering system and other dispatching software used in electric power system may be produced by different companies, because the data model, interface for accessing and the platform are different, data can't be acquired by other dispatching software from SCADA system easily. In this article, Message Oriented Middleware(MOM) based on Publish/Subscribe model is introduced into SCADA system, the structural model of MOM is designed, the working mechanism is elaborated, its function is encapsulated into COM(Component Object Model) by the technique of component, and five standard interfaces are provided for the using of application procedure, the accuracy of MOM is confirmed at last ,and the result is well.A problem-solving version that can make dispatching software and SCADA system exchange data is provided, the system's extension is enhanced greatly.
