Estimation of Oscillation mode Using ESPRIT Method

Power system transients cause problems and disturbances that might be harmful to generators. However, very little have been done to systematically understand and analyze power system transients. There is also a lack of computational effective methods as transients are short and associated with a wide range of events and system conditions. This paper addresses to propose a signal processing method, ESPRIT, for the analysis of a range of transients due to disturbance. Experimental results are included to evaluate the usefulness of ESPRIT in power system transient analysis.
