IEEE PES Central Indiana Chapter is happy to host a technical seminar on power quality given by Mr. Larry Conrad, who has over 40 years of industry experience in power reliability and quality, on March 21 at AES Indaina's Morris Street Office with free food and beverage. One professional development hour (PDH) can be offered based on requests.

Note: This seminar was rescheduled from its original planned date (March 5) due to logistic issues. Sorry for the inconvenience and look forward to seeing you on March 21.

Abstract: Voltage sags occur many times more often than electrical supply interruptions. Sags can be very disruptive when utilization equipment suddenly shuts down due to the momentary voltage reduction. The lights blink, processes quit, and workers scramble to clean up messes, recover, and return to nominal operation. This seminar will explain what sags are, what causes them and how to estimate their frequency and severity. It will also provide known strategies for minimizing and possibly eliminating their negative effects on utilization equipment.

Larry Conrad

Biography:

Larry Conrad is Owner/Manager of Conrad Technical Services LLC. He provides consulting services in electric power to electric utilities, renewable energy, and electrical design firms. Before forming Conrad Technical Services, Mr. Conrad was employed for thirty-six years in the electric utility business retiring as Director of Asset Management at Duke Energy. He is a registered Professional Engineer with B.S. degree and a M.S. degree in Electrical Engineering from Rose-Hulman Institute of Technology

Mr. Conrad served in leadership roles for asset management, power quality, reliability, emergency preparedness with a focus on distribution systems. He has always maintained special expertise in the important relationship between utility supply and utilization equipment behind the meter. Recent years include scripted hosting capacity calculations for utilities in California and New York. He helped AES Indiana lead the industry in making large solar sites work on distribution systems and shared the knowledge with others.

Mr. Conrad invented predictive voltage sag analysis published in the IEEE Gold Book. He set the framework with European utilities for the IEC 61000-3-2 Class D millennium amendment that reduced harmonics worldwide. He participated in development of the first IEEE Distributed Generation interconnection standard 1547 and was on the ballot committee for the current revision. He a member of IEEE PES Distribution Subcommittee and a long-time contributor to the IEEE 1366 reliability reporting guide. He has also served as chairman of the IEEE Volt Var Task Force focusing on conservation voltage reduction and chaired the harmonization of voltage flicker standards between IEEE and IEC. He is a long-time member of and now chairman of ANSI Committee C84 which sets the voltage standard C84.1 for the USA. C84.1 sets the preferred voltage ranges for transmission systems all the way to the wall outlets in homes.
