Program 1 Research Portfolio
Electric utilities worldwide consistently report that power quality (PQ) is a fundamental component of the three key utility business performance metrics: system performance, economic performance, and customer satisfaction. By applying EPRI's extensive PQ expertise, the Power Quality research program may help to improve these three metrics, allowing PQ managers and transmission and distribution (T&D) asset utilization and system planning professionals to use PQ-related technology, knowledge, and expertise to help improve their organization's bottom-line performance.
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.
Supplemental Project Opportunities!
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.

Call of the Month for April 2015
Via EPRI’s PQ Knowledge (PQK) Power Quality Hotline, a member asked how transformer configuration affects different kinds of faults in a three-phase electrical system. For example, faults may be phase-to-ground or phase-to-phase, transformers may have various primary and secondary winding connections (delta or wye), and the fault may occur anywhere within the system (near the source, along a feeder, or near the load). How do all of these variables determine voltage magnitude and phase angle at different points within the system?
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.

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.
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.
