在斯堪的纳维亚，相量测量应用有很大的潜力，主要是由于长距离输电和有限的输电容量扩展的可能性。基于相量测量的智能控制可以用作附加传输线路的替代方案，以增加电力传输容量。此外，阻尼问题越来越成为一个关键问题，因为负荷缓慢增加，放松管制已导致发电调度和负荷潮流的快速和意外变化增加。在瑞典，广泛的光纤通信网络已经沿着输电线路安装（主要是在塔顶的地线内部和周围）。已经进行了两次测试记录，以显示同步相量测量的能力。在冰岛，相量可以作为阻尼设备的合适输入信号，以减轻系统范围内的振荡。另一个测试是在瑞典和丹麦之间的两个星期的非常弱的连接期间，观察这两个地区之间的“自然振荡”。瑞典铁路在很大程度上由130 kV 16 2/3 Hz输电线路（/spl sim/1000 km）供电。然后变压器和变流器为接触网和列车供电。静态相量信息将是优化并联转换器操作的良好输入信号候选。
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.
