Supplemental Project Opportunities!PQ Knowledge Development and Transfer
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 4 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 December 2015 Via EPRI’s PQ Knowledge (PQK) Power Quality Hotline, a PQK member asked whether RMS voltage data from an advanced metering infrastructure (AMI) or smart revenue meter could be used to locate a fault. This Power Quality Hotline Call of the Month explores examples of using the voltage-drop method for fault location and discusses the possibilities of obtaining this data from AMI meters.
Year-at-a-Glance Calendar for Program 1 Activities
White Paper on Advanced Settings for Distributed Energy Resources
The EPRI White Paper titled Recommended Settings for Voltage and Frequency Ride-Through of Distributed Energy Resources discusses the implications of recommended advanced settings of distributed energy resources to support power quality, reliability, and the grid.
EPRI Industrial PQ Training Videos
As a follow-up to our Industrial Power Quality training classes, we have posting these complementary training videos to help solidify the concepts for both the utility members and their customers.
Video 1: Visualizing PQ Drive Parameters for Improved Voltage Sag Ride-Through
This video demonstrates the voltage sag susceptibility of AC drive systems and how to improve the drive’s robustness through parameter changes.
Video 2: Understanding PLC Voltage Sag Ride-through: AC and DC Powered Systems
This video demonstrates the differences in voltage sag ride-through between an AC powered PLC system and a DC Powered PLC system.
Video 3: Power Conditioning to Enhance Control System Voltage Sag Ride-Through: The Constant-Voltage Transformer
This video shows how a CVT can be utilized to harden the voltage sag response of an automated control system.
2016 EPRI Power Quality and Smart Distribution Conference and Exhibition
Join us this June 2016 at Georgia Tech as we look to manage the increasing complexity of the evolving Smart Grid. The Electric Power Research Institute (EPRI) and Southern Company invite you to the 2016 EPRI Smart Distribution and Power Quality (PQ) Conference and Exhibition. Also, utilities, industry representatives, and electric power end users are invited to participate by sharing their unique perspectives on the importance of addressing quality, reliability, and optimization of the power-delivery and end-use 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.
