Micro PMU
Overview
Measure and understand the complex and dynamic power flows in distribution grids and microgrids with the microPMU.
The microPMU is like a microscope that has micro-second resolution and ultra-precise accuracy needed for distribution grid applications.
The microPMU is ideal for projects that need ultra-precise synchrophasor measurements for investigating stability and impedance questions. The microPMU can also be used for real-time control applications using the IEEE C37.118.2-2011 interface.
Applications
- Monitor and understand stability of microgrids or distribution grids, and backup power systems
- Event identification and characterization
- Topology change detection (open/closed state of switches)
- Detection of cyber attacks rehearsals at substations
