Comments on Power Quality Engineering - an Assessment of Present Status

Speaker(s): 
Date: 
January 31, 2005 - 12:00pm
Location: 
Bldg. 90

This will be an informal presentation of the present status of electric power quality engineering in the United States.  A review of the main problems, power quality standards, and solutions shall be given.  The dynamic voltage restorer, transient voltage regulator, and sub-cycle transfer switch as power quality solutions shall be described for industrial applications.   Momentary voltage sags have become the most problematic power quality issue, and the analysis and categorization of these events using the CBEMA curve will be described.  The origin and engineering basis of the CBEMA curve is based on operating experience and dynamic response of single phase rectifier loads.  The seminar includes a discussion of the CBEMA curve as a power quality tool as well as how to assign costs of power quality events based on IEEE Standard 1159 and the CBEMA curve.
