Paralleling the rapid penetration of the Internet and corporate intranets, protection and control system for power systems have been quick to exploit these technologies to make the remote control and monitoring of power systems more convenient. By leveraging these networking technologies to achieve a new level of openness, Hitachi, Ltd. has now succeeded in developing a protection and control system that features an IEC (International Electrotechnical Commission)-compliant network protocol: a standardized interface in the area of protection and control systems for power systems. In addition, a compact protection and control unit was developed that incorporates Web server functionality and has the ability to be controlled and monitored over general-purpose browser software, and we are now evaluating the unit for use with various applications. Finally, efforts are also underway to develop a maintenance support navigation system that supports operations and maintenance work using an intelligent (ubiquitous) controller.
