چکیده
With the deregulation of the electrical power industry, there is a strong need for power SCADA system to interoperate with other information systems. The inleroperation between SCADA and all other systems not only needs the information sharing, but also the business or transaction-based information integration. This paper presents a Web-based architecture for power SCADA system, which is a multi-tier distributed framework using J2EE technology. This architecture combines pervasive browser with flexible user-specified application client, supports Web-service integration and transaction control, and provides a unified security policy. With the advantages of J2EE platform, this new Web-based SCADA system seamlessly integrates traditional SCADA with the enterprise information system, and exhibits more flexibility, scalability, and security than precious Web-browsing-only SCADA system.
