Engineering and Social Challenges Presented by Computers, Internet, and Communications Technology

John Bell, Wisconsin Electric Power Co.

John will present the background of a variety of computer technologies, their use, and how they have changed us. What are the strengths and weaknesses of our current level of computer technology? How and why will it improve? And, to serve whose needs? What good is the internet? What needs is it satisfying now and what can be done better? What obstacles, technical and social, are going to prevent us from realizing maximum benefit from our technology. How is our social order and structure changing in the face of this computer and communication technology? Are we ready for this? Do we really want it? Does technology define and control society or does society control technology?

John Bell graduated from Iowa State University with a Computer Science Major and full minors in Electrical Engineering, Physics, and Mathematics. John Worked on the staff of the President of the United States at Camp David for President Nixon and President Ford.

For the last 20 years, John has worked at Wisconsin Electric Power Company in the computer application development area. The first ten years work was mostly on large-scale engineering analysis programs run on a mainframe computer. Then the next five years, he was a lead scientist on an EPRI artificial intelligence project to convert paper drawings and maps to computer vector format. This technology would scan in E-size engineering drawings and then try to recognize lines, arcs, circles, and hand printed text at any angle. Engineering symbols were then recognized from the lower level geometry and text. The last five years, John has worked on web technology projects. This includes building up web servers and applications.

138 kV Swan Transmission Line and 138 kV to 24.9 kV Root River Substation

Mike Smalley, Wisconsin Electric

Swan Project - Residential, commercial, and industrial electrical load growth was increasing steadily in Southeastern Washington County, southwestern Ozaukee County, Northeastern Waukesha County, and Northwestern Milwaukee County. Three distribution substations were serving this load. All three existing substations are projected to be overloaded by 1998. To address this problem, a single transformer 138 kV to 24.9 kV distribution substation was proposed to be located at approximately 124th Street and Brown Deer Road. Previously, a second single transformer 138 kV to 24.9 kV substation was installed at approximately 68th Street and Bradley Road. The electrical source to the substations originated from an existing 138 kV double circuit transmission line.

Root River Project - An addition to the Franklin Industrial Park (60th Street and Ryan Road) was expected to add 25 MVA of peak load to the area. The three nearest substations could initially support the load if the loads were redistributed, however, shortly thereafter, all three substations would be overloaded. Additional load was expected in the area in the near future from new industrial parks and from anticipated load growth along the lake parkway. To address the near and long term loading, a new substation was proposed to be located between 27th Street and 76th Street South of Oakwood Road.

Mike Smalley received his B.S. degree in Electrical Engineering Technology from the Milwaukee School of Engineering in 1991 and the M.S. degree in Electrical Engineering from the University of Wisconsin - Milwaukee in 2000. He is a registered Professional Engineer in the State of Wisconsin. Mike a member of the IEEE Insulated Conductor Committee and serves on the Association of Edison Illuminating Company's Cable Engineering Committee. He has worked at Wisconsin Electric since 1991 holding engineering positions in the Nuclear Engineering Section, Transmission and Substation Engineering Group and is currently a Senior Engineer in the underground distribution materials and standards group.

Electrical Fast Transients ... How to Test and Suppress

Tom Moyer, Amplifier Research

Tonight's presentation will review a common and reproducible basis for evaluating the performance of electrical and electronic products when subjected to repetitive Electrical Fast Transients or classically known as EFT. Measurements are usually performed on the power supply, signal and control ports of your product. These transients may disrupt the operation of, or cause damage to the product. Testing is performed based on IEC 1000 - 4 - 4 testing standard. The EMC Directive of Europe requires this test to be performed on all products. 

Mr. Tom Moyer of "Amplifier Research - EM Test" will review this phenomenon and discuss methods of testing for EFT. A discussion on design and product suppression techniques will follow the demonstration. All that attend tonight's meeting will also receive a complementary IEEE-EMC coffee mug.

Numerical Electromagnetics applied to Clinical problems

Dale N. Buechler, Assistant Professor, Dept. of Electrical Engineering and Computer Science, University of Wisconsin-Milwaukee

Numerous advances have been made in recent years in the area of numerical electromagnetics. These advances, together with the rapid development of computer hardware over the last decade, have allowed researchers to begin to accurately solve very large problems, such as those typically encountered in the medical field. This talk will give an overview of numerical techniques commonly used for the solution of large electromagnetic problems, and will discuss current medical applications of numerical electromagnetics and potential application areas. The speaker will include some results from his research involving the calculation of the induced electric fields in the human body.

Dale N. Buechler was born in Inglewood, CA, on May 11, 1962. He received the B.S. and M.S. degrees in electrical engineering from the University of Arizona in 1984 and 1986 respectively, including completion of the Clinical engineering option. From 1984 to 1993, he was involved in clinical research in the Radiation Oncology Departments at the University of Arizona, the University of Wisconsin-Madison, and the University of Utah. In 1997, he completed his Ph.D. in electrical engineering at the University of Utah with a specialty in numerical electromagnetics. He is currently an Assistant Professor in the Department of Electrical Engineering and Computer Science at the University of Wisconsin-Milwaukee, where his research interests include numerical electromagnetics, medical instrumentation, electrophysiology, and bioelectromagnetics

Computer Simulation of Inter-laminar Insulation Failure and EL CID Testing in Large Electric Machines

Robert E. Rettler, ReGENco LLC

Maintaining the integrity of inter-laminar insulation in stator cores is important for the reliable operation of large electric machines. This presentation will demonstrate the computation of eddy currents induced where the inter-laminar insulation is imperfect, and simulates the commonly used Electromagnetic Core Imperfection Detection (EL CID) testing technique. The evaluation and analysis of EL CID data requires that the engineer must draw on previous experience with these tests and compare the new data to that which was previously encountered. Through the use of two-dimensional finite element analysis, additional insight into the core condition can be obtained. To illustrate the new finite element modeling techniques, a 1960's vintage Allis-Chalmers 200 MW generator stator is modeled. Through numerous simulations of this stator model, various fault scenarios are demonstrated. The computed results are shown to agree qualitatively with expected EL CID test results.

Robert Rettler received his BSEE degree from Marquette University in 1989 and his MSE degree from the Milwaukee School of Engineering in 1999. He currently works at ReGENco LLC in West Allis, WI. ReGENco provides turbine and generator aftermarket products and services for equipment of all manufacturers. As a Generator Engineer, he provides technical direction to utility and industrial customers of turbo-generators. He also provides engineering support on ReGENco generator rotor and stator service projects. He began his power generation career in the Engineering Department of A-C Equipment Services (ACES) in 1991. He transitioned to Siemens Power Corporation (following the purchase of ACES by Siemens) until the closure of their Milwaukee Office in 1999. Prior to joining ReGENco LLC in the spring of 2000, he was employed by Cooper Power Systems.
