Power System Harmonics Mitigation

Date: Thursday, October 23^rd, 2008

Location: SRP Information Services Building (ISB), 1600 N Priest Dr, Tempe, AZ 85281

Speaker: B. Ben Banerjee, SquareD

Topic: "Power System Harmonics Mitigation"

Typical power distribution systems at industrial facilities contain substantial non-linear loads. For example, a typical Water/Wastewater (W/WW) facility will have several electric motors as a large percentage of connected loads. In order to achieve energy conservation and mainly for process improvement and automation, many of these electric motors are fed by Variable Frequency Drives (VFDs). Depending upon the type and size of W/WW facility, one may see Ozone Generator System (OGS), UV System (UVS), and other Renewable Energy Measures like Solar Electric (Photovoltaic System or PV) as connected loads. The VFDs, OGS, UVS, and PV are all Power Electronics based equipment, non-linear in nature, and are harmonics-producing loads. This presentation will look into the power system harmonics present in industrial facilities, specifically covering topics such as:
Definition of Non-Linear Loads
Harmonics Fundamentals
Sources & Effects of Harmonics
6-Pulse & 18-Pulse VFDs
IEEE 519 Harmonics Standard
Various cost-effective mitigation techniques
Active Filters
Other application issues

Speaker Bio:
B. Ben Banerjee (IEEE M' 72) holds B.E.E degree from the University of Calcutta, India and M.E.E degree from the University of South Carolina, Columbia, SC. Presently, he is working as Power Quality Sales Application Engineer in PQ Solution Group of Square D Company, San Francisco Field Office. Prior to that, he worked for seventeen years, as Power Conditioning & Advanced Motor-Drives Manager, in Power Quality Business Group of Electric Power Research Institute (EPRI), Palo Alto, CA, where he was responsible for technology & application development for power quality mitigation hardware system, advanced energy storage for power quality solutions, and advanced motors and drives system for end-use sectors.

Prior to joining EPRI, he was Order Engineering Manager for Square D Company, Columbia, SC. In this position, he was responsible for the design and applications of products such as LV and MV MCC, motor controllers for material handling, & VFDs. He has participated in NEMA Standards Subcommittees, organized EPRI-sponsored National motors & Drives Steering Committee, and is the author/ co-author of several IEEE technical papers. His work at EPRI has generated more than thirty patents for EPRI and about eighty EPRI technical reports.
