Enhancement of power system security using synchrophasor data

This research project investigates how to improve the security of operation of a power system using

measurements taken at several locations of the power system. In the past, there was no technology

available to synchronize these measured data, and thus the applications were limited. Now, the

technology has advanced and the measured data can be synchronized using Global Positioning

Satelittes (GPS). We investigate two different approaches for enhancing system stability and thus

security. In one approach, the synchrophasor data is used along with traditional Supervisory Control

and Data Acquisition (SCADA) systems. The combined data set will then be used to determine the

transient stability margin of the operating state of the power system. This will allow the system operator

to operate the power system with the desired stability margin. The other approach is to use the

synchrophasor data in a feedback system to enhance the transient stability and oscillatory stability of

the power system. This improves the stability margin…
