2010 Lillestrøm User Group Meeting Presentations

Presentations from the PQView User Group Meeting in Lillestrøm, Norway on 16-17 November 2010 are available to download.  Photos from the meeting were also posted.

PQView 3.69.3 Released

PQView 3.69.3 is available for download.  Here are some highlights for this release:

• Installation Program Update: The PQView installation program now creates the computer ID used by PQView at the end of the installation process.
• Data Handler Updates: We updated the data handlers used to import from the following data store formats: Dranetz ESS/InfoNode servers, Qualitrol QIS databases, and Schneider Electric ION Enterprise databases.
• PQDIF Updates: The PQDIF data handler library was updated to allow client applications such as the PQView PQ Data Manager and PQDiffractor® to write harmonic and interharmonic channel group ID values in PQDIF files.  Also, the time required to export PQDIF files from within PQView’s PQ Data Manager was decreased significantly.
• RMS Voltage Variations Analysis Panel: This version includes several new tools for deriving SARFI indices, including command buttons for creating SARFI single-site and system summary tables and an overhauled SARFI Event Analysis window.

PQView 3.69.0 Released

PQView® 3.69.0 is available for download.  Here are some highlights for this release:

• Data Handler Updates: We updated the data handlers used to import from the following data store formats: IEEE COMTRADE files, Dranetz ESS/InfoNode servers, GridSense PowerView CSV Folder, Qualitrol QIS databases, SATEC PAS Databases, and Schneider Electric ION Enterprise databases.
• PQDIF Data Handler Updates: The PQDIF data handler was updated to be more compatible with a wider variety of PQDIF files that are compliant with IEEE Std 1159.3.
• CYMDIST Data Handler: We added an option to the CYMDIST data handler to convert from custom coordinate systems such as state plane to coordinate systems based on latitude and longitude.
• GroundedPower Monitoring Data Files: We added a new window for importing from text files generated by the Tendril/GroundedPower web system.
• Virtual Sites: You can now derive data for virtual sites that have voltages transformed by one to four transformer connections.  The transformer connections available include Wye/Wye, Delta/Wye, Delta/Delta, Wye/Delta, and Ungrounded Wye/Delta.  The nominal base voltage for the output voltages can be specified in line-neutral or line-line.
• PQ Event Viewer: We added event list and event roll shortcuts for events that have been processed by the optional Sag Direction Answer Module and the Capacitor Switching Answer Module.
• Harmonic Statistical Summary: We overhauled the window that displays harmonic statistical charts and updated it to allow three-phase summary charts.
• Microsoft Graph:  We upgraded numerous non-interactive charts that were dependent upon Microsoft Graph.  Microsoft Graph was the chief charting engine used by PQView 1.0 and PQView 2.0, but was replaced with a faster interactive charting engine in PQView 3.0.  The remaining charts in PQView that still use Microsoft Graph were renamed as  obsolete.  If you are using a chart marked obsolete, let us know, because they will be removed from a future version of PQView.

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 on-line.  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 3.66.0 Released

PQView 3.66.0 is available for download.

We completed nearly sixty changes to PQView in upgrading from version 3.65.1 to 3.66.0.  Here are some highlights:

• Microsoft Access 2010: This version of PQView includes support for the just released Microsoft Access 2010.  We also posted the free Microsoft Access 2010 runtime edition for download.
• Microsoft Access 2007: Some users reported problems using PQView with Access 2007.  We discovered that there was a defect in the original release of Access 2007 that prevented launching PQView.  Microsoft corrected the problem in Microsoft Office 2007 Service Pack 1 (SP1).  In PQView 3.66.0, the PQView Launcher and PQView Agent applications will show a warning message if your computer is using the original release of Access 2007, and will advise you to install SP1 or SP2.
• Updates to Data Handlers: The following data handlers were updated: PQView 2.x/3.x Databases, IEEE COMTRADE Folders (No Map), Dranetz-BMI PASS 8010 PQNode Database, and GridSense PowerView Text Files.
• Data Handler for GridSense PowerView Text Files:  The data handler was updated to import waveform samples and rms samples from event files.  Previously, you could import data log measurements only.
• SEL Report Files: We added a new window for importing from report files created by Schweitzer Engineering Labs (SEL).  The only report supported by the window with this release is the Load Profile (LDP) report.  We plan to expand on this window in the future to import other SEL report files, including EVE, CEV, and SSI.  Until then, there is a separate data handler specifically designed to import EVE files.
• 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).
  Fault Analysis Window: We added three new charts: distribution of maximum voltage, maximum voltage per fault event, and maximum voltage per fault event in a time line display.  The fault data for this report is added by the optional Reactance-to-Fault Add-in Module.
• Follow-On Fault Analysis Window: We added a new window that analyzes faults that “follow” other faults measured by a site at the same station.
