The microPMU Wall mount package is a field solution to deploy ultraprecise phasor measurements in distribution and smart grids. This technology enables the analysis of the effects of the high penetration of renewables on distribution and microgrids.

The microPMU Wall-mount Package consists of:

•  IP44 rated enclosure and internal wiring
•  terminal blocks for easy external wiring
•  microPMU synchrophasor instrument (millidegree/2PPM accuracy)
•  GPS-R synchronization module and antenna
•  Internal power supply and UPS battery backup 1 hour
•  microPMU self powers from its measured voltage

The microPMU

The microPMU is a synchrophasor that high speed records and streams real-time stamped data measurements of electricity, including voltage, current, and frequency, as phasors at different points on a utility electric grid transmission system. Use a synchrophasor for wide area measurement and control to understand complex and dynamic power grid applications in utility distribution grids and microgrids.

How Powerside’s Synchrophasor Technology Works

Powerside’s microPMU works like a microscope with micro-second resolution and accuracy needed to understand the distribution of power grid applications. The microPMU data provides grid operators with a precise and high-resolution image and pmu measurements of the power grid in real-time.

Powersides’ microPMU takes PMU measurements at 30 observations per second. Each measurement is time-stamped according to a common time reference using GPS. The time-stamping of the measurements allows data from different locations and utilities to be time-aligned (synchronized) and combined together. This data provides a precise and complete overview of the entire gride interconnection.

This time-sensitive information helps to alert the grid operators to grid stress early on, potentially avoiding power outages and maintaining power quality.

It’s easy for system operators to install. It can be installed in electrical panels, on distribution poles, in pad mount transformers, and more.

The microPMU is also ideal for smart grid projects that need precise synchrophasor measurements to investigate grid stability problems and to answer questions on blockages.

The basic system building blocks of an application are GPS satellite-synchronized clocks, phasor measurement units (PMUs), a phasor data concentrator (PDC), communications equipment, and visualization software. Some applications for the microPMU include:

•  Stability of microgrids or distribution grids, or power generation systems
•  Event identification and characterization
•  Topology change detection (open/closed state of switches)
•  Detection of cyber-attack rehearsals at substations
