Power System Stabilizer Design
July 12, 2017

PSC’s Anupama Konara to speak at 2017 IEEE PES general meeting.  Utilities need to tune new and existing Power System Stabilizers (PSS) to ensure stability of their power systems as network topologies evolve and new system stresses emerge. PSS act on generator excitation controls to provide positive damping to low frequency oscillations. PSS tuning involves determining settings that work under multiple operating conditions and is typically validated using computer simulations.

PSC’s Anupama Konara will be presenting a new PSS design technique this July at the 2017 IEEE PES General Meeting in Chicago, IL. While there are several methods that facilitate a design of a robust PSS, the eigenstructure assignment method provides an efficient means for solving the optimization problem due to smaller solution space. Phasor measurement units (PMUs) are installed at several utilities around the world for real time monitoring of power systems. A future application of synchrophasor technology is the use of remotely measured signals in feedback control applications such as PSS. Anupama will also demonstrate how remote signals can be used to design more robust power system stabilizers.

The 2017 IEEE General Meeting will be held on July 16-20, in Chicago, IL. More information about the conference can be found at pes-gm.org.
