User Group Presentations from New York Meeting in 2010

Presentations from the 2010 PQView Users Group Meeting in New York City, USA are now available online.  The posted files include an overview of changes in PQView in 2010, an overview of PQView's role at Con Edison in New York City, and how PQView is being used by Shanghai Municipal Electric Power Company to support the Shanghai World Expo.  Two product spots are included, including demonstrations on displaying power quality data using OPC tools and visualizing fault data using ESRI software packages.  TVA presented results from a fault waveform signature analysis project, and EPRI presented initial results from a transmission capacitor analysis project.  EPRI also presented a summary of IEEE PQDIF translator projects.

Training modules from the 2010 Advanced PQView Workshop were also posted, demonstrating how to import data from GridSense PowerView text files, Dranetz InfoNodes, and Schneider Electric ION Enterprise databases.


PQView 3.68.1 Released

PQView 3.68.1 is available for download

We completed nearly two hundred changes to PQView in upgrading from version 3.66.0 to 3.68.1.  Here are some highlights:

  • PQView Users Group Meetings: During August and September, more than ninety users participated in PQView training sessions in New Zealand, Australia, China, and New York.  This PQView release includes many changes specifically requested at these training sessions.
  • Charting Libraries: We upgraded the charting engine used for interactive charts in PQView.  The new charting engine renders charts about 60% faster, which will be most evident when making a chart with hundreds of thousands or millions of data points.  The chart engine now uses modern Windows charting technologies such as GDI+, antialiased text, and antialiased graphics.  The most noticeable enhancement is an optional zoom window that will appear at the bottom of each chart once you zoom in.  The zoom chart shows the entire chart and highlights the area that is currently zoomed.
  • Updates to Data Handlers: We updated the data handlers or modules used to import from the following data store formats: IEEE COMTRADE Folders, Dranetz ESS/InfoNode, Schneider Electric ION Enterprise, Unipower PQ Secure databases, SoftSwitching I-Grid, OSISoft PI System, PQView databases, and SEL Report Files.
  • Updates to PQView Agent: We modified the way in which PQDM instances shut down when launched from PQView Agent.  As an option, you can have PQDM terminate itself after a data source import initiated by PQView Agent.  This option prevents PQDM instances being left stranded after a Microsoft Access automatic restart.
  • RAS Support: We made major improvements in PQDM when used to download Dranetz InfoNodes using dial-up networking (RAS) connections.
  • Proxy Server Support: We added support for specifying proxy server settings when downloading measurements from InfoNode and I-Grid servers.
  • Fault Viewer: The Fault Viewer in PQDA now features a command button that can export one-line diagrams to applications associated with KML files (e.g., Google Earth)..
  • ANEEL Calculations: The derivations for indices required by the Brazilian National Electrical Energy Agency were modified to include monitor availability as part of the precarious and critical voltage ratio.
