Abstract

The electric power utilities are continuously working on improvements of the network system, such that numerous different technological, environmental and economical requirements from authorities and customers can be satisfied. For this purpose the electric network system is redesigned and reinforced although the increase in demand for electrical power is moderate. In particular, an increasing focus on aesthetic and environmental requirements have implied that overhead lines are replaced by cables, and old high polluting power plants are renewed with more environmentally feasible production units, and production from new renewable energy sources. The challenge of the future network design will be to meet these requirements by application of new high effective technologies in the network system. The new high temperature superconducting power components represent a new generation of system components for application in the electric utility networks because these devices have an inherent capability of operating at higher power ratings while exhibiting lower losses than conventional components. The superconducting fault current limiter (SFCL) is such a new system component with a peculiar limitation characteristic that is unknown in the conventional fault current protection scheme. It is therefore expected that an introduction of SFCL in the electric power supply system can result in considerable improvements with concern to power supply quality, voltage quality and network flexibility. This paper discusses the results of a questionnaire survey within the Danish electric utilities. The survey describes the expectations within the Danish electric utilities regarding the application of SFCL in the Danish transmission and distribution network with concern to needs, characteristic ratings and criterions of operation.
