Abstract	There is a great potential for phasor measurement applications in Scandinavia, mainly due to the long distance power transmission and limited transmission capacity expansion possibilities. Smart control, based on phasor measurements, can be used as an alternative to additional transmission lines, to increase power transmission capacity. Also the matter of damping is more and more becoming a key issue, since load is slowly increasing and the de-regulation has caused an increase in fast and unexpected changes of generation dispatch and load flow. In Sweden an extensive optic fiber communication network has been installed along the transmission lines (mainly inside and around the ground wire at the top of the tower). Two test recordings have been performed to show the capability of synchronized phasor measurements. In Iceland phasors could be suitable input signal to damping equipment designed to mitigate system wide oscillations. An other test was made to see the "natural oscillations" between Sweden and Denmark during a 2 week period of very weak connection between the two areas. The Swedish railway is to a large extent fed by a 130 kV 16 2/3 Hz transmission line (/spl sim/1000 km). Transformers and converters then feed the contact line and the trains. Static phasor information would be a good input signal candidate to optimize the parallel converter operation.
