Java']Java-based applications for accessing power system data via intranet, extranet and internet

This paper demonstrates the development of a Java-based application that can be used for information exchange by a variety of market participants, such as generators, brokers, market operators, and network owners. For an illustration, a SCADA Laboratory Applications Program (SLAP) has been implemented. Java Graphical User Interface (GUT), Object Management Group's Common Object Request Broker Architecture (OMG's CORBA) and multi-tiered Client/Server Architecture are some of the software technologies used. A three-phase design approach, which ensures a high probability of success for developing the Java-based application for data access via Intranet, Extranet and Internet, is also presented. Based on this Java-based application, an open geographical distributed environment where power system data can be shared reused and accessed from anywhere can be created at a much reduced cost.
