Operational Applications in the Power Delivery System

Abstract

The operation of the electrical power system requires the exchange of information between different constituents of the system. The exchanged information is constantly evolving from simple signals such as commands and binary status data toward more elaborate forms such as coded measurements, control messages, and enriched situational information. Power system operation also necessitates the interaction of human operators across the system as well as their interaction with field-located power system components or remotely located operational information systems. From original control room voice communication covering power plants, substations, and load dispatch centers, the power system operation is moving to more elaborate modes of communication such as mobile data systems, remote access to field assets, and field worker access to central support platforms and information systems.
