【主讲人简介】

Kenneth Martin is a principal engineer with the Electric Power Group (EPG).  He has over 40years experience in the electric utility industry, first at the Bonneville Power Administration (BPA) in communication, precise timing, instrumentation, and testing.  He started working with synchrophasor measurement with the original PMUs in 1987 and conducted the first PMU tests.  He developed the phasor measurement system at BPA including building the first phasor data concentrator, and supported similar developments at many utilities.  Mr. Martin chaired the development of the IEEE C37.118 Synchrophasor Standards from the 2005 original, through the 2014 amendment.  He was a lead for the IEC 61850, part 90-5 and is the convener for 60255-118-1 developing the joint IEC-IEEE measurement standard.Mr. Martin is a Fellow of the IEEE and a registered Professional Engineer.  He has authored or co-authored more than60 articles and technical papers.

【内容简介】

Phasor measurement systems have become widespread in the United States. The majority of the used is for operation analysis and model validation, with some use of visualization applications, but none for mission critical operation. This project is developing three real time applications that will use phasors for mission critical applications. Real Time Contingency Analysis uses a current model to determine the vulnerability to future failures. A new application is being developed that will use the solved model provided by linear state estimation and phasor measurement. System phase angles from phasors can be used to assess angle differences caused by power flow. The second application uses the overall angles to detect line losses that weaken the grid. Another problem that can be difficult to assess is power flow through a corridor that includes many lines. The complex voltage and current measurements from phasors at the edges of a corridor can be used to assess the overall voltage stability across the grid. This is the third application that will be discussed. The presentation will give an overview of these applications and discuss some of the implementation challenges.
