DataNXT

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.

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.

Finding Root Causes

DataNXT identifies the root causes of bad and uncertain data.

Identify the Sources of Bad/Uncertain Data

DataNXT pinpoints to the source of the problems – Which TO’s, communication channels, PMU’s, signals are sending out bad, uncertain or invalid data?.

Finding Issues with Timing of Data

When was the data missing, bad or uncertain and for how long?

Conditioning Bad Data

Making data usable for down-stream applications: Replace data with last good value, user entered value, NaN (Not a Number), LSE determined values

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
