Data Quality Management Platform

DataNXT is an advanced Synchrophasor Data Quality Management platform. DataNXT performs data validation and conditioning to solve data quality problems like Drop-outs, Time synchronization issues, Bad/Frozen signal values, Communication errors, and Measurement calibration issues.

Use Cases of DataNXT

Determining Data Availability and Data Quality

DataNXT helps to find out the amount of data is missing and how much of the data is good, bad or uncertain.

Key Features

  • Data Distribution (Outputs)

  • User selectable multiple outputs can be configured for sending data to different applications. Example, down-sampled data for EMS, full resolution for Visualization, Archiving and Reporting
  • Reporting

  • A highly customizable, web-based, high-performance, real-time Data Quality Reporting tool capable of generating manual (ad-hoc) and periodic automated reports with emailing capability. A wide range of User-customizable reports are available
  • Detecting Errors

  • in Synchro-Phasor Data based on User Configured Validations
  • Flagging Data

  • using Standard based Quality Codes for Achieving and sending to Real-Time Applications
  • Extended DataNXT Capabilities Include:

    • Time Synchronization and Concentration (PDC Functionality) of Phasor data from multiple Sources – PMUs, PDCs
    • Linear State Estimator (LSE) – For Advanced Model-based Validation and Conditioning
    • ICCP Output Adapter – For EMS Interchange
    • DNP3 Output Adapter – EMS/SCADA Input
    • PI Historian Adapter – For Archiving
    • Input Stream Failover – For Input Stream Backup
    • Redundant PMU Selection for Output – Based on PMU Status Flag and Latency

About EPG

Electric Power Group, LLC (EPG) has been pioneering the development and deployment of synchro-phasor technologies since 2000. Our principals have extensive experience in running and managing utility grids, investigating root causes of major blackouts (WECC 1996, EI 2003), and leveraging this deep domain knowledge to develop industry leading synchrophasor technology applications for wide area real time monitoring, visualization and situational awareness.

The EPG team has extensive hands-on experience with synchrophasor standards, networks, system architecture, deployments and performance analysis through work at EPG for leading ISO's and utilities including PJM, NYISO, ERCOT, CAISO, MISO, BPA, TVA, SCE, AEP, LADWP, SRP, Duke, Dominion, NYPA and other companies.
