Intranet-based supervisory control system for power systems

摘要

We have developed an intranet-based supervisory control and data acquisition (SCADA) system for power systems. Its basic architecture consists of Internet technology and it has the same advantages, such as ever-growing use for fully interoperableinformation interchange, that Internet technology has.In the process of realizing the intranet-based SCADA, middleware was developed in order to resolve concerns about real-time performance and availability of the system. This middleware enables a system to replicate the real-time distributed databases ofoperators, the Web browser to display with sufficient rapidity, and the system to automatically recover from a failure between geographically separated servers on the intranet.
