Introduction
The Swedish transmission system is a vital part of the electricity system. The
transmission system transports massive amount of energy from areas of production
to areas of consumption. We base many important functions of our society on the
fact that the transmission system always work. So far it does work!
Sweden has an old transmission system that was built very robust with large
margins. Electricity has gradually become a more and more popular way of
transporting and using energy. Therefore, the margins are shrinking and thereby
also the robustness is challenged. Svenska kraftnät, the Swedish transmission
system operator, is taking many different actions to increase the robustness. One
such action is to closely monitor the condition of components in the system.
Condition monitoring is nothing new and is performed in many ways. In order to
make the monitoring efficient, it should be automated. Automatic condition
monitoring is normally based on data analysis using different kinds of algorithms.
The work leading up to this midway seminar has been focussed on a few algorithms
that has been successfully demonstrated to work in the Swedish transmission
system.
