Application of Synchrophasor Measurements for distribution networks

Wide Area Monitoring with Synchrophasor Measurements has become of great interest in supervision of stability for transmission systems. With the acquisition of the phasor measurements using Phasor Measurement Units (PMU), a new quality of insight into the dynamic behavior of the electric power network has become possible. The value of this method is increasing because of more dynamic requirements for the system caused by renewable power infeed such as wind and solar and energy trade. The renewable power infeed goes to a quite high amount into the distribution networks so that at that level, also the dynamic processes are increasing. The distribution networks are taking over more tasks that have been reserved for transmission networks in the past, so the supervision is also important for the distribution level. This paper discusses applications for that. An example for the use of synchrophasors for energy accounting is given. Finally, the status of standardization is presented.
