PQView / PQWeb Users Group

The PQView® Users Group is intended to assist power quality engineers in managing and analyzing power quality data. The user group's purpose is to support and inform the PQView user and to provide a forum for communication and sharing of ideas among its members.

PQ Knowledge Development and Transfer (Formerly PS1D) 

Management of power quality issues has never been an easy task, but it has grown even more difficult with deregulation, reregulation, increasingly scarce technical and strategic tools, and a conspicuous lack of unbiased resources for information, collaboration, advice, and problem solving. Moreover, with the ever-increasing use of sensitive digital and electronic equipment in today’s economy, end-use customers are not only demanding higher quality power, but also are calling upon utilities to help resolve PQ problems within customer facilities.

This supplemental project offers a number of benefits for members, including leveraging contributions by at least a 20-to-1 ratio, access to EPRI experts and industry peers, access to high-impact resources, such as documents covering a wide range of PQ topics, and access to MyPQ.epri.com, a comprehensive electronic PQ resource providing 24/7 access to more than 500 PQ case studies, PQ technical documents, PQ standards references, indexes, conference presentations, and a wealth of other resources.

PQView® Upgrade Project Opportunity 

PQView® Upgrade project opportunity: Introduction and discussion of a new supplemental project opportunity for broadly upgrading PQView.

PQView® was initially developed over 15 years ago in collaboration with utilities. Since that time, PQView has become a leading industry tool for managing large databases of power system monitoring information and for visualizing power quality data. It is used by many utilities as the foundation for collecting information from a variety of different monitors, managing the database of disturbance and steady state data, reporting on performance, and providing alarms and notifications for problem conditions.

This research initiative focuses on development and implementation of an enhanced PQView database, modernizing PQView’s architecture, and improving PQView’s Graphical User Interface (GUI). Work undertaken in each phase will be scaled – with input and guidance from project funders – to reflect overall funding. Phase 1 of this effort will create PQView Explorer v1 and PQWeb Explorer v1 – usable software that will comprise and deploy enhanced PQView capabilities as they are created.

Call of the Month for July 2015
Via EPRI’s PQ Knowledge (PQK) Power Quality Hotline, a PQK member asked for an update regarding the possibility of concentrations of photovoltaic (PV) installations causing emissions that interfere with nearby equipment, such as digital revenue meters. This topic had originally been introduced in the May 2011 PQ Hotline Call of the Month, and the PQK member inquired whether there were any conclusions that came out of that episode.
PQ News Builder

For EPRI PQ Knowledge funders, we have created a tool that enables you to download articles related to power quality, including high-resolution images for printing or PDF file. You can select articles on a variety of topics from our Power Quality Database and download content in HTML or RTF format, which opens in Microsoft Word.

Assessment of Retrofit Energy Saving Device (RESD) Technologies 

Retrofit energy saving device (RESD) technologies have garnered attention with a variety of performance claims including reduced energy costs and power quality mitigation. This project will undertake the evaluation of one or more RESD technologies to compare performance in the lab and field to performance claims.
