Recent Trends in Power Quality Improvement for Industrial Systems


Presented by: David D. Shipp, Thomas J. Dionise, Tamer Abdelazim Mellik

Lunch will be provided between 12pm and 1pm.

This tutorial will cover the fundamentals of power quality as it relates to power systems feeding electronic loads and how these problems manifest themselves as control issues, lockups of computers, extremely slow operations, failed components and other nuisance conditions. The major elements to be covered will be harmonics, electronic grounding and voltage disturbances. The tutorial will cover harmonic generation, control and basic mitigation techniques, IEEE 519 and where it applies. It will address electronic grounding, national electric code requirements, basic techniques involving single point grounding, electrical noise elimination and ways to recognize and mitigate grounding problems. The tutorial will explore voltage disturbances involving sags, swells, outages, impulses, switching transients as well as mitigation techniques such as Sag Ride-Thru and Drive Ride-Thru Devices, Surge Protective Devices, Un-interruptible Power Supplies, — and their various types. A session will cover how these power quality issues accompany variable speed drive applications — both on the input to the drive and the output to the motor — including motor failures, and drive input/output filtering solutions. Additionally, switching transients as related to power quality will illustrate how these problems result in equipment failures, both immediate and over time. Multiple real world examples and practical solutions will be presented throughout the tutorial. The attendee should be able to recognize, design and mitigate the more common problems associated with power quality issues after attending this tutorial.

David D. Shipp, PE, (IEEE – S’72-M’72-SM’92-F’02-Life F’14 / SPE M’95) received the B.S.E.E. degree from The Oregon State University, Corvallis, Oregon, USA in 1972. He recently retired from Eaton Corporation’s Electrical Services and Systems where he was a Fellow Engineer and prior to that, spent 26 years with Westinghouse doing similar responsibilities. He presently is a consulting engineer with his company Capstone Power Systems Engineering and a Life Fellow Engineer in the Institute of Electrical and Electronic Engineers (IEEE). He has spent many years performing the engineering work associated with his present-day capabilities, which include a wide range of services covering consulting, design, power quality, Sine wave filter designs, arc flash, grounding, switching transients and power systems analysis topics. He has written over 90 technical papers on power system analysis topics including 12 for the Society of Petroleum Engineers. Approximately 25 technical papers have been published in IEEE/IAS international magazines and two in EC&M. Several papers have been awarded prize paper designations. Mr. Shipp is currently a key member of the IEEE I&CPS-sponsored Working Group on generator grounding. He is very active in IEEE at the national level and helps write the IEEE Color Book series standards. He has spent 27+ years working with the oil and Gas industry solving ESP electrical problems involving life extension / extending ESP run times. He takes solutions learned from other industries and works with the ESP industry to retrofit these solutions into their unique environment. He has been awarded 2 Meritorious Awards for Engineering Innovation in the Oil and Gas industry from Hart’s E&P Magazine. He occasionally serves as a legal expert witness

Thomas J. Dionise, PE


Thomas J. Dionise, PE, (S’79-M’82-F’19) received a B.S.E.E. degree from The Pennsylvania State University, University Park, in 1982, and the M.S.E.E. degree with the Power Option from Carnegie Mellon University, Pittsburgh, PA, in 1984. He is currently a Power Quality Advisory Engineer in the Power System Engineering Department, with Eaton Corporation, Warrendale. He has 37 years of power system experience involving analytical studies and power quality investigations of industrial and commercial power systems. In the metals industry, he has specialized in power quality investigations, harmonic analysis and harmonic filter design for electric arc furnaces, rectifiers and drive applications. He has co-authored 40 papers, several of which received IAS Transactions, Magazine and conference Prize Paper Awards. Mr. Dionise is the Past Chair of the IEEE Metal Industry Committee and member of the Generator Grounding Working Group. He is a licensed Professional Engineer in Pennsylvania
