Record Phasor Measurement Unit (PMU) Data for Analysis

EPM 9900P PMU/Synchophasor Functionality

The EPM 9900P meter has been enhanced with Phasor Measurement Unit (PMU) functionality meeting the IEEE C37.118.1a-2014 standard. A PMU device measures time-synchronized, phasor (magnitude and phase angle of voltage and current) and related data from a specific location on the electrical grid. The data from multiple PMUs are transmitted to a phasor data concentrator (PDC), which aggregates and time-aligns the data for real time and post analysis.

Collection of Synchrophasor data is useful in applications such as:

• Aggregation of instantaneous, time synchronized voltage, current, and frequency at specific locations on the grid for easy greater wide-area system operator situational awareness
• Determination of stress points of the utility transmission system
• Detect and aid in restoration an islanded section of the grid after a storm or major outage disturbance
• Collection and integration of PMU data for visualization in an Energy Management System (EMS).
