DESCRIPTION:Prof. Ali Abur (Professor at Northeastern University\, Boston\
 , MA\, USA)\nAbstract: This talk presents a method to detect permanent err
 ors in utility data bases related to branch parameters. The method will fi
 rst be described for systems explicitly containing fully transposed lines 
 and symmetric branch models. It will then be extended to three-phase non-s
 ymmetrical mixed-phase power networks. The first method uses output of exi
 sting state estimators to enable detection and differentiation between err
 ors in analog measurements and branch model parameters. The main advantage
 s of the method are that it does not require modification of existing stat
 e estimators\, it is a stand-alone application which can be executed on or
  offline\, does not require any user intervention or a priori selection of
  a suspect parameter set\, and can identify all existing erroneous paramet
 ers in a large-scale power system data base while differentiating them fro
 m any existing measurement errors. Modal decomposition and compensation me
 thods will be used to extend the method to three-phase systems. The talk w
 ill also cover an alternative robust state estimation method which can sim
 ultaneously estimate the system states and parameter errors. The talk will
  provide results obtained by applying the developed techniques to syntheti
 c as well as actual power systems.\n\nBio:  Ali Abur obtained his B.S. de
 gree from Orta Doğu Teknik niversitesi\, Turkey and both his M.S. and Ph.
 D. degrees from the Ohio State University\, Columbus\, Ohio. He was a facu
 lty member at Texas A&M University until November 2005 when he joined the 
 faculty of Northeastern University as a Professor and Chair of the Electri
 cal and Computer Engineering Department. His research and educational acti
 vities have been in the area of power systems. He is a Fellow of the IEEE 
 for his work on power system state estimation. He co-authored a book and p
 ublished widely in IEEE journals and conferences.
