Gridradar offers a supra-regional insight into the state of the electricity grid in real time. For this purpose, Gridradar uses measuring stations across Europe, its own and cooperative so-called "Phasor Measurement Units" (PMUs for short). By means of Multi-GNSS, we ensure an exact temporal alignment of the PMUs.
The power grid is constantly in motion, power plants suddenly change their mode of operation, grid elements fail, large consumers unexpectedly shift production - all these effects have an impact on the grid and can be measured via the frequency, among other things.
Weather phenomena, such as storms or the approach of a cloud front, also constantly change the feed-in and consumption situation. As a result, load flows shift unexpectedly both regionally and supraregionally. Physical load flows can not only be simulated, but can also be measured using the phase angle difference. We are continuously expanding our monitoring system; the denser the measurement network, the more precisely load flows can be monitored.
The data from this wide area monitoring system is automatically evaluated in a powerful, geographically distributed analysis system. This guarantees the availability of the information even if there are failures in the system. The map shows the current load flows.
