Research output: Contribution to specialist publicationArticle


The information & control system currently used in electric power systems is a client-server-type distributed system connected by networks. It offers remarkably operational improvement compared to conventional systems. Sophisticated supervisory control technologies are applied using enhanced-performance hardware. The information & control functions of individual servers enable analysis and assessment of on-line data from a range of perspectives. The system is designed for maximum compactness through the application of compact hardware. Furthermore, high-speed large-capacity network, real-time distributed-database structure, and sophisticated human-interface system assist operators of electric power systems to make decisions and contribute to secure electric power supply.
