A channel and inventory system for power system telecommunications at Swedish national grid

This paper describes the development of a channel and inventory system (CIS) for power system telecommunications. The system is novel, since no other similar systems have been found. The system is based on a software shell, originally aimed for the process industry, but here developed for telecommunication purposes. The system is in full operation at Swedish National Grid and it has been accepted on a wide scale. This paper highlights the approach for using a supplier based on rapid prototyping. The solution relies on an object-oriented structure, where a worldwide web interface generates adequate user information, which is invaluable for fault location, fault handling, and telecommunication planning. The CIS possesses several flexible properties, which can be expanded and further developed.
