Oscillation Monitoring and Control of the RTE Power System Using Synchrophasors (S-81G)

Summary Recent advances in design of fast oscillation monitoring algorithms have paved the way for real-time detection and analysis of electromechanical oscillations from wide-area synchrophasor measurements in large power interconnections. The oscillations if left unmitigated can lead to unwanted tripping of transmission lines and generators that could cascade into devastating blackouts. Oscillation monitoring algorithms developed at Washington State University have previously been implemented and tested in North American power grid and in India. In this project, we will study oscillation phenomena in the RTE portion of the European power grid by using available synchrophasor data. Suitability of ambient versus ringdown analysis algorithms for analyzing recent oscillation events in RTE will be investigated. Oscillation analysis results using transmission level PMUs will be compared with corresponding results using distribution level Phasor Measurement Units (PMUs). The effectiveness of the oscillation algorithms will be tested and improved by using simulated PMU data from dynamic models of the RTE system wherein the expected answers are known from small-signal analysis of the dynamic models. New oscillation analysis and control algorithms will be developed in the project as needed in collaboration with RTE to address the oscillation issues in RTE.
