PQView® 3.65.1 Released

2010-05-12T18:09:40Z

PQView 3.65.1 is available for download. We completed nearly one hundred changes to PQView in upgrading from version 3.64.0 to 3.65.1. Here are some highlights:

PQView Launcher: A shortcut to a new application now appears rather than the traditional shortcuts to the Power Quality Data Manager and the Power Quality Data Analyzer. PQView Launcher allows you to use PQView without having write permission to the “Program Files” folder where PQView is usually installed, which provides better compatibility with Microsoft Windows Vista and Windows 7. It also allows you to have more than one PQView application open at a time. For example, you could have three instances of PQDA open at one time, each connected to a different PQView database. PQView Launcher can be used to “trust” folders when using Microsoft Access 2007 or Access 2010; a database in a trusted folder can be opened without any warning messages from Microsoft Access.
PQView Agent was upgraded to work on Microsoft Windows 2003 Server and Windows 2008 Server.
Updates to Data Handlers: The following data handlers were updated: IEEE Std 37.111 COMTRADE Folders, IEEE Std 37.111 COMTRADE Folders with No Mapping, Dranetz® PASS/PNDS Databases, Dranetz® ESS/InfoNode, Electro Industries® Communicator Log, and SoftSwitching® I-Grid® Web Site.
Data Handler for Electro Industries Communicator Log: This data handler was redesigned to load data log samples in batches. This change means that large volumes of data will be imported up to 400% faster than when using PQView 3.64.0.
PQ Event Roll: We modified the functionality of the Auto Zoom checkbox. When checked, the time axis of all charts in the same PQ Event Roll window will be zoomed together. That is, when one chart with time values for an x-axis is zoomed, all other charts will have their x-axis zoom modified to match the zoom of the chart that was just zoomed. This feature has been requested by many users in the past.
Optional Fault Location Add-in Module: The add-in module was updated to show the distance to fault in miles or kilometers when non-default values of line parameters are specified. This makes it easier to use the add-in module with transmission line data. For distribution circuits, the Fault Viewer was updated to allow one-line diagrams to be displayed that show only the line segments with phases that correspond to the fault phases.
Derivation of ANEEL Indices: We revised the module in the PQView PQ Data Manager used to derive indices required by the Brazilian Electricity Regulatory Agency (ANEEL). We also added an ANEEL report in the PQView PQ Data Analyzer.
Steady State Trends Window: You can create a new derived chart that cross tabulates the values in the trend chart by day. This allows each day being plotted to be overlaid on top of each other day.

PQView was featured in a recent article written by Tennessee Valley Authority and EPRI for T&D World Magazine.

User Group Presentations from Knoxville Meeting in 2006

2010-03-12T16:40:53Z

Presentations from the 2006 PQView Users Group Meeting in Knoxville are now available on-line.

The meeting focused on PQView 3.27. The archive includes presentations describing how to import measurements from Schneider Electric ION Enterprise® Databases, the I-Grid® Server, Square D® System Manager Databases, Dranetz-BMI Power Xplorer® files, Dranetz-BMI InfoNode® Servers, and Fluke Scenario databases. It also includes a presentation on the ONS Approach for Power Quality Management at the Transmission Level in Brazil. Two cases studies were presented. One was a study on power system interharmonics from a cycloconverter, and the other was the first use of PQView as part of an automatic distribution fault location system.

User Group Presentations from New York Meeting in 2005

2010-03-05T23:01:17Z

Presentations and photos from the 2005 PQView Users Group Meeting in New York are now available on-line. This meeting was hosted by the Consolidated Edison Company of New York and was held on April 5 in Manhattan.

The archive includes presentations from both the user group meeting and the user training workshop. The meeting focused on PQView 3.22, PQWeb 3.2, using the built-in IEEE COMTRADE Viewer in PQDM, importing data directly from InfoNode® servers, importing IEEE PQDIF files from the I-Grid® web site, and running the imbalance analysis module in PQView.

User Group Meeting Presentations from 2004

2010-02-26T21:56:17Z

Presentations from the 2004 PQView Users Group Meeting are now available on-line. This was the ninth annual PQView Users Group Meeting and it was held in Knoxville, Tennessee, USA.

The archive includes presentations from both the user group meeting and the user training workshops. The meeting focused on PQView 3.19, PQWeb 3.2, the built-in IEEE COMTRADE Viewer in PQDM, importing IEEE PQDIF files, and importing from Fluke/RPM Scenario databases. We presented an overview of PQView use in Macau and in Guangzhou. A special case study was examined in which we used PQView to analyze waveforms with 2.5 million samples.

Electrotek Survey for Standard Desktop/Laptop Computer Configuration

2010-02-19T16:31:30Z

Results from Electrotek's "Survey for Standard Desktop/Laptop Computer Configuration" have been posted on-line. The purpose of the survey was to collect information about the typical workstation computer and laptop computer used by PQView users today and in one year. The results will direct planning and design of new PQView software.

PQView 3.64.0 Released

2010-02-15T17:51:20Z

PQView 3.64.0 is available for download. This is the first version that includes support for Microsoft Access 2007. This release also features more than one hundred updates to PQView Agent, PQDA, and PQDM. The following data handlers were updated: Dranetz-BMI PASS/PNDS Databases, IEEE Std 1159.3 PQDIF Files, IEEE Std 37.111 COMTRADE Folders with No Mapping, Landis+Gyr® MAXsys 2510 Text File Folder, and the SCADA Database for APC. Version 3.64.0 features more SCADA integration functions and an optional incipient fault location function.

User Group Meeting Presentations from 2003

2010-02-09T20:34:03Z

Presentations from the 2003 PQView Users Group Meeting are now available on-line. This was the eighth annual PQView Users Group Meeting and it was held in Knoxville, Tennessee, USA.

The archive includes presentations from both the user group meeting and the user training workshops. The meeting focused on PQView 3.11.0, PQWeb 3.1, importing IEEE COMTRADE Files, importing IEEE PQDIF files, and importing Cooper V-Flicker PST Text Files. The meeting also had a presentation on power quality sag indices used by Tennessee Valley Authority, a case study by Duke Power relating the experience of running PQWeb on a hosted web server, and an overview from American Electric Power on a PQDIF Translator for General Electric HHF files produced by the KV meter. Electrotek presented case studies on using PQView for analyzing wind energy applications, and also presented the results from a small survey on changing levels of voltage total harmonic distortion (THD).

From the PQView Users Group Workshop, we have posted the three training modules: Adding RMS Voltage Variations from Value Logs, Exploring the New PQDM Options Form, and Query String Properties for the Event List of PQWeb 3.1.
