PQView 3.73.0 Released  

PQView® 3.73.0 is available for download.

This release includes nearly 150 changes to PQView.  The changes result in improvements in all major components of the PQView application. 

Icons for PQView PQ Data Manager and PQView PQ Data Analyzer: The graphics for the program icons and splash screens for PQDM and PQDA were updated.  They now use the same theme used for PQView Agent.

Support for Microsoft® SQL Server® 2012: We made more changes to allow PQView applications to open more quickly when used with databases hosted by SQL Server 2012.  Also, the PQView23.sql script shipped with PQView was modified slightly to be more compatible with RTM edition of SQL Server 2012.

PQView Database Library: We made more than nine changes to the PQView Database Library that is used by an increasing number of third-party software engineers to query measurements from a PQView database.  Some of the changes include the important bug fixes in the subroutines that return statistics.  We also added properties that allow you to filter steady-state samples and harmonic samples based on valid minimum and maximum values.  New methods were also added for determining compliance for rms voltage, line frequency, negative-sequence unbalance, voltage THD, voltage fluctuations, and individual harmonics.

PQView Agent: You can now use PQView Agent to send overdue data source e-mail notifications.  That is, a PQView Agent instance running on one computer can send an e-mail notification if the data source owned by another computer is overdue for import.

Data Handlers for IEEE PQDIF Files: We made many improvements in the IEEE Std. 1159.3 PQDIF data handlers, focusing on improving our support of more types of data that can stored in a PQDIF file, and on better handling of errors encountered in PQDM during import of PQDIF files that do not completely follow the IEEE 1159.3 standard.

Data Handlers for IEEE COMTRADE Files: We improved the data source importing code for IEEE COMTRADE files, making it easier for PQDM to log problems with COMTRADE files noncompliant with IEEE Std C37.111-1991/1999. 

Data Handler for Dranetz InfoNode Servers: You can now specify the maximum number of PQDIF record chunks to download from an InfoNode server during an import session.  The default used to be 1000, but was upgraded to 5000 in PQView 3.70.0  Starting with this release, you can specify larger numbers of PQDIF chunks to download as an option. 

Data Handler for SoftSwitching Technologies I-Grid Web Site: We added options in the Data Source Setup that allow you to deselect import of Transient Events and Power Up Events. These options are not enabled for an existing data source, so be sure to mark them in your existing PQView database if you want to continue to import these characteristics.

Data Handler for ISO System Loads:  We added a new data handler to download and import data from the following Independent System Operators in North America: Electric Reliability Council of Texas (ERCOT), ISO New England (ISO-NE), New York ISO (NYISO), Ontario Independent Electricity System Operator (IESO), and the Pennsylvania-New Jersey-Maryland Interconnection (PJM).

Silver Spring Networks Integration: You can now import voltage, current, and energy data from Silver Spring Networks export files. Silver Spring Networks provides services for collecting and managing data from smart energy meters. 

Other Data Handlers: We improved other data handlers in this new PQView version as well, including the modules used to import from the following sources: BTECH Battery Validation Manager, Electro Industries Communicator Log, and Schweitzer Engineering Laboratories® (SEL) EVE Folders.

Compliance Reporting: The functionality associated with the Compliance Setup Window in PQDM, which began in 2007, is finally completed.  The window allows you to create a configuration file usable by PQDM to create XML and HTML compliance reports.  The compliance setup includes the ability to specify two compliance intervals, which would allow computation of special compliance indices like “precarious voltage” required by ANEEL in Brazil.  Also, the PQView PQ Data Manager can now produce a compliance summary report for rms voltage, negative-sequence unbalance, voltage fluctuations (Pst and Plt), voltage THD, and individual voltage harmonics.

Steady State Trends Window: You can now specify the list of specific harmonics to display using commas, semicolons, and hyphens.  For example, if you set the harmonic text box to the string “1,2,3,10-12;21-25”, then the following harmonics would be trended: 1,2,3,10,11,12,21,22,23, and 24.  You can also specify another code to display inclusive lists of just the odd harmonics or just the even harmonics.  Also, you  can now display numeric site property values from a drop-down list box on the trend, histogram, and profile chart as horizontal or vertical line annotations.
