Operational Applications in the Power Delivery System
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. The evolution of information exchange across the power system needs to be assessed in order to determine the size, type, and perimeter of the telecommunication network that the Electrical Power Utility (EPU) should implement whether this is achieved through the deployment of a dedicated infrastructure or through provisioning of services over the network infrastructure of a telecom provider. Figure 1.1 provides a basic model defining “user applications” interacting through a communication service delivered over a dedicated telecom infrastructure or provisioned through an operator (procured service). The Service Access Point is the point of delivery, monitoring and management for the communication service and the interface between service user and provider. Communication services in the EPU are generally identified with the applications they serve (e.g., SCADA or protection communication services). This is indeed based on a common understanding of the telecom service provider and the application owner of the communication requirements. This is true when dealing with long-established power system applications delivered by internal telecom facilities. The same cannot be assumed when new applications are being introduced or when provisioning services from an external provider.
