Highlights of 2020 Changes – System Center

Open PQ Dashboard User's Group - April 9, 2020

A new application to manage configuration data in an integrated way for all applications in the openXDA suite of toolsWill include a “configuration change” alarm for substation measurement devicesProvides integration with other corporate tools to reduce configuration burden and improve configuration quality Work Management (Maximo) for asset

attributes (e.g., structure locations) Planning (FAWG) for equipment electrical

characteristics Active Directory for contact management

6

A new asset-centric model has been implemented in openXDAProvides the ability to designate spare breakers and switch out breakers serving linesAllows voltage measurements to be associated with all equipment attached to the busAlso includes modeling of line segments – each with their individual impedance characteristicEach segment can be connected: To another segment To 2 other segments (a tap) To the substation

Highlights of 2020 Changes – Automated Analytics

Open PQ Dashboard User's Group - April 9, 2020

Currently, these assets can be modeled:LineBreakerBusTransformerCapacitor Bank

7

Version 3.0 supports the expanded openXDA asset information model

Highlights of 2020 Changes – Event Visualization

Open PQ Dashboard User's Group - April 9, 2020

This list-based tool provides an e-mail like interface to find and preview multiple dimensions of event data

Planned for late 2020 this new tool is a portal into openXDA data for key-accounts and industrial customers

8

PQDIF Explorer Verifies PQDIF Files Displays Meta-data in PQDIF files for

investigationPQ waveform data parser Can read COMTRADE, SEL and PQDIF

files Displays waveforms for visual analysisPQio Converts data from PQDIF to PQDS

format EPRI PQDS format is easy to read, csv-

like file format for PQ data

GPA Helper Tools – PQio, PQwdp and PQDIF Explorer

Ability to interrogate substation devices using vendor specific, proprietary protocols ION meters Dranetz 61000s

FTP-based polling is included in the open-source version of openMIC.

Ability to horizontally scale into a high-availability, load-balanced systemAbility place devices in a substation where there has been a breaker operation at the top of polling queueAvailable at the cost of standard maintenance for openMIC

Highlights of 2020 Changes – Data Acquisition

Open PQ Dashboard User's Group - April 9, 2020

10

Devices where data can be downloaded via FTP in standard PQDIF or COMTRADE format.Non-standard files that openXDA can parse: EMAX event files APP trending data files

(coming summer 2020) SEL CEV and SEL EVE -- for most relay

models SEL Trending Data Files

(coming summer 2020)

openMIC EE (coming summer 2020) Dranetz 61000s ION Meters
